Upsizing / Tuning

What is it for?

TireHub helps you choose the best tires and wheels to tune up your car! Select the original sizes and check the complete information about the tires, wheels, conditions and guidelines for upsizing it according to the law.

Suitable for

Professionals.

Purpose

Present the best conditions and models of tires and wheels to tune up your car.

How to use it

First select the size of your original tires and wheels, then select the size you want to install and check the ideal conditions for customization below.

On-Vehicle Analysis

We can estimate how the new wheel/tire assembly will fit into your vehicle by analyzing the distance (clearance) of the new suspension component assembly, the distance to the fender and wheel box, thus anticipating possible impacts between the components. We can also predict the impact on vehicle performance and stability by analyzing the change in static radius (ground height) and the difference between the speedometer and the actual speed. To do this, enter the data of the vehicles original wheel and that of the new desired wheel.

Does it fit or not?

Suspension Clearance 165.15 mm

Assembly closer from suspension components in 16.52cm. Risk of contact between components.


Fenders Clearance 57.15 mm

Assembly closer from fenders components in 5.71cm. Risk of contact between components.

Wheelbox Clearance 0.00 mm

Same condition as original.


Static Radius 0.00 mm

Same condition as original.


Speedometer after Modification 100.00km/h

Pressure Corrections

When changing tire and wheels sizes, the front and rear axles pressures of the vehicle must be adjusted. The following calculations provide the minimum pressure required to operate in the new condition, but these pressures may require additional adjustments to suit the vehicles dynamic behavior.

Pressures for unloaded vehicle

Original Pressure PSI
Front Axle - Unloaded

Original Pressure PSI
Rear Axle - Unloaded

New condition

Minimum Pressure after Modification 0 PSI
Front Axle - Unloaded

Minimum Pressure after Modification 0 PSI
Rear Axle - Unloaded


Pressures for loaded vehicle

Original Pressure PSI
Front Axle - Loaded

Original Pressure PSI
Rear Axle - Loaded

New condition

Minimum Pressure after Modification 0 PSI
