Question regarding wheel sizes?
Hi guys,

I've been told over the yrs not to put too large a wheels into the car as it'll affect the axle and the diffs.

But my question is if I keep the total diameter of the wheel+tire same but I just change the wheel from 14" to 16" would it matter? What's the logic behind this? I thought moment of inertia would be based on the weight and radius of the wheel+tire height and not just the wheel height.

Let me know.

thanks guys.

Cheated on my いたずらな女の子 and now I can't get enough of her..

Question regarding wheel sizes?
I don´t think the moment of interia is the problem with bigger wheels. Its the overall gearing.
If you change to bigger wheels with a low profile tyres, while your outside diameter stays the same you won´t change your gearing, same stress on drivetrain than before.
Therefore if you change from, lets say 185/60/R14 to 195/45/15 you will reduce stress and the car will get handle better, during the low profile.

BTW low profile tyres can look very stupid, if your car is not low enough...

It'll always look stupid if it's not low enough. Tongue
