If my car understeers at 80kph with 205F/205R on a given corner then it will still understeer at 80kph on the same corner with say 205F/245R. It is just that i will be able to get more grip from the rear. This is not my concern tho. I need to know how i can reduce the effects of bump steer/trameling without changing my wheels. Someone please give me an answer to THIS question. I don't care about under and over steer. No, your car will just understeer MORE. When the front tyres approach the point where they loose some grip, the back wheels will not. The front slip angle will be greater than at the back and you will understeer. You can't really argue with physics. There is a good book on the subject written by a car engineer called 'handling and roadholding' I think - you should read it. You SHOULD be concerned with understeer etc as it will have a big effect on what your car is like to drive. By all means put huge fat tyres on the back - I really don't think it will be as fun to drive anymore. May as well buy a fwd. If you have a monster engine and you HAVE to have wider rear tyres, worry about it then. BTW Porshes etc are designed like that from the factory to work with their suspension. Also, I read that the ra6x celica has a 52/48 weight distribution, which is pretty near optimum for a rear wheel drive. [Report message to a moderator]
