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.

Hi Anubhav,

Thanks for writing in!

An easy way to reduce unsprung weight is to replace stock wheels with special lightweight wheels. As you are looking for lightweight tyre under 11 kg, I would suggest you go for Goodyear Assurance TripleMax - 205/65 R16 95H. It falls under 11kg category and is a good option to go with considering the starting price.

What could be recommended tyre size for Qualis FS 1 (Manual steering)? Present tyres are Bridgestone L607 175 R14. However not getting the same now !

I would recommend 195/70 R14 91H for your car as this is the most suitable size to provide good grip and stability. You can consider buying Yokohama A.Drive AA01.
