A Guide To Using Upsized Tyres In Your Vehicle

While performance plays a significant role in determining how attractive a vehicle is, its aesthetic qualities seal the deal. Fitting larger tyres can spice up its appearance, giving it a sporty or rugged look that many drivers like. But most automobile and tyre manufacturers recommend that you mount tyres that match the rim specifications perfectly. So, should you consider upscaling at all?

Merits Of Upscaling:

While the motivation behind upsizing lies in stylising their vehicles for most motorists, there are also some technical advantages. Handling and cornering are enhanced, accounting for the increased stability and traction of the car. Off-road tyres demand larger tyres for better adhesion on the rough terrains.

Demerits Of Upscaling:

Despite its benefits, there is a reason manufacturers suggest against sizing up. Such tyres add to the weight of the vehicle, affecting its performance. It might even throw its balance off, making your rides bumpy and uncomfortable.

The pros of upsizing can outweigh its cons if you follow a few ground rules. These include:

Getting The Right Upscaled Size

The markings should look something like this: 175 / 70 / R-13. Each of these letters and numbers represents a detail about the tyre dimensions. You should know how to read these to determine the correct tyre size. Here 175, measured in millimetres, indicates the tread width remaining in contact with the road surface. The 70 that follows right after implies the height of the sidewall. It is calculated as a percentage of the tyre width.

Checking The Load Index

Every tyre has its load-bearing ability, exceeding which can put a critical strain on it. Tyres that match the car specifications are fit to carry its entire weight. So, when you are upscaling, you have to make sure the new tyres are too. In terms of load index, the value should be greater than or equal to the recommended one.

Checking The Speed Index

The maximum speed at which you can run a tyre is known as its speed rating. When you buy a pair or a quartet of tyres, ensure that their ratings equal the original or recommended ones.

Not Touching The Vehicle

If you decide to go for larger tyres, make sure they do not stay in contact with the car’s bodywork. Pay close attention to how they interact with the fender while going over bumps and speed breakers.

Proportioning The Sidewall And The Width

The height of the sidewall and width should always remain in constant proportions. If you go for a broad set of tyres, each of their sidewalls must be reduced.

Adjusting The Speedometer

The speedometer and other electric components of the vehicle are calibrated to the original equipment. So, if you switch to a set of bigger tyres, they have to be readjusted to cater to the change.

Final Words:
