well yeah for a start it's illegal to run two different sizes and then also the steering/handling will defo be all over the place because of the tyres aswell.
lol, no its not illegal, several cars run different size tyres front and rear as standard!
As long as there on the same axle it's ok, not ideal on a clio though.
Not if there on the front and the back, as in 205's on the front, 195's on the back it will be fine! As said, a lot of bmw's, elise's etc are like that anyway!
nice one! still not gonna help this guy's cause though and should be sorted asap imo!
^ABS does go mental if you lean on it, if you have ESP it really s**ts itself with different tyre sizes front and rear
I'm not sure how it would make a difference really? I could never tell the difference when running odd or same all round and I have ABS and ESP. I'd say the difference would be far worse if say you had cheap s**tty 205 on the front and good 205 on the rear.
different overall circumference? one pair of wheels would be travelling slightly faster/slower than the other set??
