Rules for tyre upsizing

Generally, tyre upsizing is shared among all. You can see many car owners frequently fixing wider tyres in their vehicles. If you see Car buffs, they drive their cars straight to a tyre shop for an immediate upsizing. Some do it for aesthetic purpose, whereas some consider tyre upsizing for obtaining improved driving dynamics. Even though the job seems easy, you shall find many factors while going for tyre upsizing. Since even a tiny change in your tyre directly plays a role in safety and performance, the job should be done with professional advice. Let us read the rules of upsizing tyres.

Speed Rating

Always check with the speed rating of your replacement tyre. Ensure that your replacement tyre’s speed rating should be higher or similar than the original. If it is lower, you should be limiting yourself throughout the driving time of your car. A person who is not aware of such limitation and made to handle your vehicle, it may be held up with a dangerous situation to that driver. So, always ensure your new tyre speed rating is at least as much as the original pair.

Proportionality of Sidewall and width

It is always recommended to maintain the correct ratio in sidewall and width. There is a thumb rule that has to be applied during tyre upsizing i.e., if the tyre width is increased, the tyre sidewalls must be comparably decreased. If you are going for wide Tyres Saltcoats, then the tyre profile must be reduced proportionally. If you decide to go for higher-profile tyres, you shall adapt to a lean set of tyres. A bigger wheel always requires a wider tyre.

No intact with the car’s body

Make sure that your tyre is not making contact with the body of the vehicle. Every vehicle is designed to be adjusted with specific tyre sizes, and going beyond the limits can make tyres to rub in opposite to the fender. You shall take special care to check whether the tyre is free to move even in the loaded condition and passing on uneven roads.

Recalibrate speedometer

Since the speedometer, electronics, and other configurations of the car are taken into account the tyre circumference, altering the tyre size can be called for recalibration. Hence, either be sure that the perimeter of replacement tyres is identical as before or get advice from a professional to get your speedometer & others configured.

How is tyre upsizing performed?

This is performed in two ways by installing wider tyres, retaining the original wheels of the car, and altering the tyres and wheels.

Both methods are easy to perform. However, they have pros and cons. The second method is more striking than the first as changing the tyres' specifications, especially for more significant wheels, upgrades the look of your car. It improves your overall handling, traction, and safety of the ride. Increased weight due to the fixing of larger wheels and a higher level of traction due to the larger width contribute to decreasing your vehicle's acceleration. Comparatively, the second method is more costly since altering wheels with tyres is always expensive.

Upsizing and benefits

Better braking

The braking system makes a significant difference between a safe and dangerous journey. Wider tyres support cars to stop in the minimum distance with decreased time. It makes you feel secure while travelling along with your beloved family.

Improved grip

Wider tyres will have broader contact with roads. It allows the weight of your vehicle to distribute in a better way to make your car more fixed, particularly at high speeds.

Superior cornering ability

To hold the centre of gravity, it is essential to increase the tyre width and decrease the sidewall height. Tall sidewall tyres produce more contracts compared to low-profile car tyres. It will make the car feel unstable when turning your car at high speeds. Better traction level is offered by upsizing, and it thus reduces such stated risks.

Overall, the broader tyres guarantee you improved balance, excellent stability, and good traction
