Method Used for Tyre Upsize Calculation

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

    Tyre Dimension Measurement
    Total Diameter = Wheel/Rim Diameter + Sidewall

This total diameter can only be increased by 3%, for a safe upsize of tyre. So, we calculate the total diameter for each tyre size and then compare this with the total diameter of the size that is originally fitted in your car.
If the difference lies within this range of 3 %, then only we would recommend that tyre.
