Excuse my ignorance but why would it lose traction in the wet?
Maybe I should explain why all the questions
I have a classic panda fitted with 165 tyres. My daughter wants a car with lighter steering so I'm going to fit 135 tyres which were standard on the panda. I have two wheels with 135 tyres on and was wondering about fitting them while I get the other wheels refurbed. I don't want to put my daughter in danger so hence the questions. (She is not a fast driver and has never got even close to any limit of grip.)
