Rules for tyre upsizing-April 2024

Introduction

Swanky large tyres undoubtedly look cool and also enhance the overall appearance of your car. However, there are some ground rules for tyre upsizing. Upgrading to larger tyres, or tyre upsizing, has several advantages – it improves the car’s handling and cornering abilities, and offers better stability. Off-road vehicles use bigger tyres to gain some ground clearance and improve the footprint, thereby providing better grip.

At the same time, there are disadvantages too. For one, larger wheels are heavier and hamper the performance of the vehicle. Also, with an increase in the unsprung weight, the ride is not going to be as comfortable as it was before. Nevertheless, if you are ready to take the plunge, here are a few things you need to keep in mind before going for tyre upsizing.

Load Holding Capacity

Firstly, check the load holding capacity of the replacement tyre. Manufacturers finalise specific tyre for the car taking into account various factors, including the load-bearing capacity. As such, always ensure that the load-bearing capacity of the replacement tyres is equal to, if not higher, than that of the stock set of tyres. Loading up the car with excess weight can cause the tyre to burst, potentially causing an accident.

Speed Rating

Although a majority of the tyres out there will be compatible with road-legal cars, it is a good practise to check the speed rating of the replacement tyre. Just like the load holding capacity, the speed rating of the replacement tyre must also be similar or higher than the original set. In case it is lower, you might be capable of restraining yourself throughout the time you drive the car. But it would not really be a good idea to hand over your vehicle to someone who isn’t aware of this limitation and can be at risk. Hence, always make sure the speed rating of the new tyres is at least as much as that of the original set.

No contact with the car’s body

At all times, ensure that the tyres do not make contact with the car’s body. Every car is engineered to be compatible with certain tyre sizes, and going above these limits can cause the tyre to rub against the fender. Special care has to be taken to check whether the tyre has free movement even when the car is fully loaded and while going over uneven surfaces.

Sidewall and width proportionality

It is very important to maintain proportionality in sidewall and width. The thumb rule while tyre upsizing is - if the width of the tyre is increased, the sidewalls of the tyre must be proportionally decreased. In case you are opting for a wider tyre, then you will have to reduce the profile of the tyre proportionally. On the other hand, going for a higher profile tyre means that you will have to make do with a skinnier set of tyres. Opting for a bigger wheel necessitates going for a wider tyre.

Recalibrate speedometer

The speedometer and electronics of the car are configured taking into account the circumference of the tyre. Therefore, a change in the tyre size calls for recalibrating these. So either ensure that the circumference of the replacement tyres is the same as before, or consult a professional to have the speedometer and electronics reconfigured.
