In our previous blog post we shared about uneven tyre wear and what causes it. In this post we are exploring about new tyres and benefits of changing old tyres.
The tyres life span is measured by the driver’s handling, the road conditions, the climate and there is no guarantee that how long the tyre last.The regular care for your tyres like alignment,suspension specification,uneven tyre tread,air pressure can extend your tyres lifespan.
The life span of tyres can increase or decrease based on the driver’s handling, the road conditions, the climatic conditions.
If your tyres crossed 40,000 km or 5 years in use, kindly check your tyre’s condition by a professional.
Occasionally your tyres can last more than 7 years but as a precaution replace them with new tyres and use your old tyres as spares.
How Your Tyre Gets Damaged?
One of the main reason your tyres gets damaged quickly depends on your driving; sudden breaking, and driving on the damaged roads can get your tyres damaged easily.
Your car’s Wheel rim should match your tyre size else it can damage the whole wheel system and can cause uneven tyre wear.
Even the climate changes can also affect your tyre’s condition due to variation in temperature on summer and rainy season.
Your tyres can also be damaged by speed bumps, sharp objects and obstacles.
Check the air pressure when you go for a long drive because if it is not maintained according to the manufacturers recommendations , the vehicles tyres will wear out fast .
Benefits Of New Tyre:
New tyres give the potential for the higher acceleration on the highways and better grip for your vehicle to stop (ABS can work more effectively) and turn, you don’t have to hesitate or be scared of tyres skidding during rainy days because new tyres provide better grip.
The tyre’s performance is based on the tread designs and quality of your tyres. Tyres are changed according to your vehicle’s type(Hatchback, Sedan, Suv) and based on your weather condition for better performance.Better grip translates into better performance.
The Uneven tyre wear causes wobbling and vibration which can affect your mileage badly.New tyres don’t wear out early and you can drive comfortably and it can improve your vehicle’s mileage as there is no pressure on the tyres.
Uncomfortable tyres can spoil your mood for driving, but new tyres are with strong tread, design. Which makes your long ride smoother and better. Compared to your worn out tyres, new tyres are less noisy.
Changing your old tyres won’t cost much for you. It is an one-time investment since you’re going to replace your tyres for once in 7 years ; we are not going to replace all tyres at the same time. For a comfortable and safe ride check your tyres regularly.
Tip : keep a spare tyre good condition with proper tread, it might come in handy at times.
Cars have become part and parcel of day to day sustenance but buying one is not a takeaway for everyone. Not all are gifted to get a brand new eye-candy to boast off, and some may have to settle with second-hand products. But why should one feel bad about getting a used car if it looks good, runs well and satisfies the needs? Here are a few pointers to check on before deciding on purchasing a used car.
The type of car, the purse amount and the type of usage must be taken into account before deciding to go for a car.
The type of car would essentially mean the number of people most likely to travel in it
The type of usage would mean long or short drives and the type of terrain the car would be subjected to while being driven.
Once the model is fixed up in mind, second-hand purchases become quite easy because there would be a single-minded set of questions to be asked to various people regarding that model only. Always ask two or three authorised dealers before fixing on an estimate.
Open the bonnet:
Cars appearing like this from behind might have problems in the front like this.
So it is always better to have a compartmentalised view of the car before deciding to go for it.
The heart of the vehicle should be checked thoroughly, mostly with the help of a mechanic or a person with adequate hands-on experience with automobiles. The flywheels would get rusty after prolonged usage. Checking the engine also means investigating every small component associated with it right from the bearings to the valves.
The belt drives associated with the engines are also mandatory checkpoints. These belts are usually toothed and hence any deformation in the tooth would mean the car has been used too much. The degree of elasticity of the belt would also transform to the quality and quantity of usage. When the belt is slightly pulled and released, the vibratory oscillations should not be more than 1 to 1.5 centimetres.
Usage and distance:
This is one important perspective while buying a second-hand car. If a car is assumed to run for about 30 kilometres a day, it would mean 30 * 365 = 10,950, which can be translated to approximately 11,000 kilometres a year. So if a car (if it is not a taxi) has run more than 75,000 kilometres (which roughly equals 7 years of usage), there are high chances that that particular model has become obsolete. So think twice before buying these kinds of models, because used cars would require a lot of maintenance (at least initially) and hence the spares should be readily available.
Appearance and body:
The car must be examined visually and also by touch. There are certain minor bumps and dents which might not be visible to the naked eye but on sliding the hands over the exterior of the car, one might be able to sense the minor glitches.
The paint and coating also matters; if the car looks old after a sneak peek into the bonnet but it has been painted, there might be recent accidents and paints would mean effective cover-ups. So make sure the paints are used only for the aesthetic needs and not to deceive the buyer.
Tyres, which literally set the wheels in motion, are potential sources of implied information. The distances shown in the odometer of the vehicle can be duped but the tyres would show up variations. Tyres are usually meant to operate for around 25,000 kilometers before replacement. Even if the odometer is being reset (in the case of a digital one) or tampered (in the case of a mechanical type), the tyres can act as good measures of guesstimating the approximate run.
For detailed information, the owner’s service log may be examined to check the history of services. This would give a clear-cut picture of how many services the car has undergone, which would eventually decide if one can buy it or not.
This is where the steering and ABC (acceleration, brake and clutch) of the vehicles come into play significantly. The gears should be shifted by keeping the clutch partially pressed (this condition is called as half-clutch position); this would indicate the smoothness of the transmission system. While shifting, if the gear lever becomes rigid, or if it is harder for shifting, then it means the transmission needs to be looked into.
Also, the vehicle shouldn’t give a rugged feel while driving. Unnecessary wobbles and a roaring noise (typically like that of a note sustained in a bass guitar) at speed ranges of 50 to 70 kilometres per hour would imply the car might cause several problems like engine failure in the near future.
The differentials of the car can be put to test by performing slight turns. If the opposite pairs of tyres (right in the case of a left turn, and left for a right turn) tend to be a bit draggy during the turn, the car might very well be towards its finals stages.
Power steerings are not susceptible to failure very easily; they usually give warning signs before they fail permanently. The initial warning signals would be a freakish screech heard every time the steering is turned to beyond 50 to 60 degrees. This is a minor stage which can be overcome by replacing the steering fluid.
Another way to know the steering effectiveness is to serve it using a single hand. If there is a difficulty in taking a 60-degree turn within 10 meters at 20 km/hr, it is a warning sign that the steering might give in.
Once the deal is settled, make sure to get all the required papers like RC book, insurance documents and other ownership transfer details from the owner so as to avoid any legal disputes and issues.
Cost and quality are two factors separated by a thin line, especially in the case of used car purchase. Be informed, look close and don’t fall for word magic. Think for a second to buy a second-hand car. Vrooom !
Hot On Wheels is a saying dedicated to the blitzing drivers who make rough use of their tyres of the automobiles. As it is commonly seen with almost all components, fatigue becomes an issue with tyres also, especially since they are being constantly exposed to continuous contact with the road, thereby developing frictional heating. This might result in faults or tears in the tyres, eventually making them unfit for on-road drives. Replacing the tyre is one important measure that needs to be done regularly with periodic maintenance and monitoring.
After deciding to fit in a new tyre in your vehicle, there is a particularly very important criterion that needs to be looked into, so as to get the maximum effectiveness from them. This aspect deals with the size and overall dimensions of the tyre to be incorporated. Retrofitting is an easy procedure but care must be taken regarding the diameter and thickness of the rubber materials.
There are mainly two different types of size defects related to tyres. They are oversizing and undersizing. Both result in the improper or inefficient functioning of not only the tyres, but also bring to question the whole dynamic balancing of the vehicle. This would make the tyre susceptible to mechanical wear and tear, irreparable losses and wobbling of the body while in motion.
Oversizing is the condition where the tyres diameter is higher than what used to be the original dimensions of the default tyre. This would affect the speed range of the vehicle, and the speedometer readings might mislead to wrong conclusions. This is because the speedometer is usually calibrated to the standard dimensions of tyre for every revolution.
If the size of tyre is increased, the time taken to complete a single revolution will be increased. Hence, the number of revolutions per minute (rpm) would correspondingly decrease. This would cause drastic effects in the gear shifting pattern of the vehicle. For cars with automatic transmission system, the gear shift would significantly get affected because it works on sensors that sense the cycles of rotation. Now if the cycle gets modified, the sensors might sense ambiguous speed ranges, thereby affecting the performance of the vehicle.
On the other hand, undersizing (the condition where the dimensions of the tyre retrofitted becomes smaller than the required size) might lead to enhanced difficulties with the rim. Small size of the tyre would mean that it would be fitted over the rim by exerting extra force. This always makes the tyre subject to extra pressures within them even when they are idle (cold pressures). Moreover, the load bearing capacity of the vehicle is usually vested to be borne only by the tyres. If their load gets reduced, it might put unnecessary weight on them thereby making them susceptible to more problems, and also taking a toll on the overall efficiency of the vehicle concerned.
So it is always a better practice to check for the exact dimensions of the tyre to be fitted in before getting it fixed into the vehicle. Tyres are one of the most important companions when you are cruising on road, make sure they are fit enough to carry the momentum forward, quite literally.
For any vehicle owner, one of the most frequently occurring problems is the one that are related to the tyres of the automobiles. Be it two wheelers or their big brothers, this tyre wear and the eventual replacement becomes a periodic issue to be addressed. Since this happens at prescribed intervals (until and unless the vehicle meets with a calamitous accident), the rhetorical question of whether to buy a used tyre or a new one comes into existence every time there is a slight non-repairable loss to the bottom-most foundation of the vehicle. Here is a guide that would help you decide better.
Some of the most important factors that come into play while choosing the vital decision are the distance travelled, the tread depth, the tyre dimensions, the price range, and finally, the brand.
The common running distance for a car tyre is anywhere between 60,000 kilometers and 1,60,000 kilometers. The maximum limit is a bit far-fetched and is feasible only under ideal conditions of temperatures at around 30 degree Celsius and the road terrains being very flat and uniform with less curves and potholes.
While choosing a used tyre for a car, it is always a good practice to go for those that have run a distance close to the lower limit (that is, 60,000 to 75,000 kilometers, or roughly between 40,000 and 45,000 miles). However, this is a difficult criteria to find out because the number of punctures fixed and mended cannot be ascertained straightaway by looking at a used tyre.
Coming to bikes, the distance range is from 12,000 to 20,000 kilometers. So the safety limit of buying would be between the lower limit and upwards until 15,000 kilometers (No tyre owner can be expected to sell it before at least the minimum prescribed distance has already been covered)
In some of the recent tyre models, the year of make is inscribed at the side of surface. This might be a great indicator to estimate the distance traveled, keeping in mind the average distance the tyre would have covered every day. Common day-to-day travels can be estimated to be around 30 to 40 kilometers for ease of calculation.
Though all these are great guesstimates, they are based on mathematical gambles which may or may not work out. So the other factors must be duly taken into account, too.
The price bracket:
First of all, it is common knowledge that the used tyres come at a very lower price relatively in comparison with the new ones, especially for the four wheelers. The general advice would be to go for the used tyre purchase if the deal can sealed at the price that is one-third of the actual price of the new one. Even this 1/3rd ratio is feasible only for tyres that are close to their lower limit distance of travel.
For tyres which are found to have run more than 50 kilometers a day, it is not advisable to go for the old ones, especially if the tyres have covered greater part of their lifetime within the local driving limits; this is because while driving within the localized region (for example, amidst city traffic or a congested region), the tyres might have to take a lot of turns, and they would also be forced to excessive fatigue due to comparatively more braking, which produces a lot of heat due to the frictional contact between the road and tyre.
So considering the cost being spent, it is okay to go for a used tyre for about 30% of its original cost, if its driven distance is near the lower limit. Else, it would be sane to opt for a new tyre.
Even if the tread depth is within the range, any deviation from its usual pattern (the pattern is based on whether the tyre has symmetrical or asymmetrical tread) makes the tyre still unfit for reuse. Retreading is an option that can be considered here but this technique would be possible again only if the tyre fulfils the distance and cost criteria as mentioned in the earlier sections.
There are unaware mistakes that tend to happen because of the slight negligence of the buyers of used tyre who fail to take note of the minute difference in the outer dimensions of the tyre. This might lead to either oversizing or downsizing. Both of them have their own pros and cons associated with it. Go for them only if you know about Oversized and undersized tyres
To sum up, the purchase of tyres depends upon the longevity expected from the purchaser and the type of vehicle that is under consideration. It is also dependent on the type of usage and the turfs in which the vehicle would be driven.
Tip: If only one of the tyres need to be replaced, try to fit the used tyre in the rear wheel in case of a two-wheeler. If the front tyre gets damaged and is in the hour of change, use the undamaged rear tyre for the front and fit the used one in the rear axle.
For four wheelers, since the Indian regulations instruct the drivers to “Keep Left”, it would be safe to go for the used tyre to be fit in the right rear side as the first choice. This is because during the turns (both left and right), there will always be more pressures relatively on the left pairs of the tyres. So the right side that has less pressure exertion is a good choice. It is also necessary to note that the rear pairs have comparatively lower pressure ranges. So the right rear is the first and best choice for replacement.
