Tyre upsizing means changing your regular tyres with wider tyres so as to enhance the tyre performance.

There are two things that can be done to upsize a tyre:


  • Selecting a wider tyre and/or

  • Choosing a larger wheel.


There are several advantages of upgrading the tyres to a larger size. Tyre plus sizing improves:

  • The handling of the vehicle along with its stability and its cornering abilities.

  • For off-roading vehicles, bigger tyres for achieving some ground clearance and enhancing the grip of the car or the bike.

  • The last advantage is, of course, the attractive look these tyres give to the vehicle.


There are also a few disadvantages of sized up tyres. The larger the wheels, the heavier the car becomes and it starts hampering the performance of the vehicle. The ride also gets uncomfortable at times due to an increase in weight.

Upsizing works on the concept of increasing the wheel size and decreasing the profile of the tyre so as to achieve greater look and performance and maintain its original size as well.

There are three types of tyre upsizes:

After looking at all the pros and cons of increasing the size of tyres, if you plan to upsize tyres, there are few things that you have to check:

  1. Check the Load Holding Capacity


It is important to check the tyre load holding capacity of the new tyre. Makers choose a particular tyre for the vehicle considering different variables, including the tyre load bearing limit. One must always make sure that the load-bearing capacity of the substitution tyres is equivalent to or higher than the stock of tyres. Stacking up the vehicle with overabundance weight can make the tyre burst, possibly causing a mishap.

    

  1. Check the Speed Rating


It is also very important to check the speed rating of the replacement tyres. Much the same as the load bearing limit, the speed rating of the substitution tyre should likewise be comparative or higher than the first set.

 

  1. Check the Proportion of Sidewall and the Width


The thumb rule while tyre upsizing is - if the width of the tyre is expanded, the sidewalls of the tyre must be relatively diminished. On the off chance that you are selecting a more extensive tyre, at that point you should decrease the profile of the tyre relatively.

 

  1.  Improve the Speedometer


As the speedometer and hardware of the vehicle are arranged considering the boundary of the tyre, replacing the tyre size can call for recalibrating of these. So one must ensure that the outline of the replaced tyres is the same as the old one, or one must counsel an expert to have the speedometer and gadgets reconfigured.

     

  1. No contact with the car’s body


It is important to ensure that tyre doesn't touch the vehicle's body at all. This is the primary thing you have to guarantee. Each vehicle is built to be good with certain tyre sizes, and going over these points of confinement can make the tyre rub against the bumper. This should not happen.

Tyre upsizing/Tyre plus sizing calculation method

There is not much scope to increase the total diameter of the tyre that comes originally fitted in your car.

Total Diameter = Wheel/Rim Diameter + Sidewall

For a safe upsized a tyre, one should only increase the total diameter by 3%. Therefore, one should calculate the diameter of the originally fitted tyre and the new tyre and compare them.
