Tyre Size Issues

tj9 · 04-06-2010, 07:33 PM

I recently went to my dealership and they changed my two front tyres for me free of charge.

Unfortunetly... They changed the two front tyre to a 225/40/18, cant quite remember what the original fronts were, i think it was 225/35/18 if im not mistaken. Anyway, on the back is a 245/35/18.

Would this setup affect the car in the long run with a higher profile in the front?

Thanks

With the stock 18" wheels and ZSP, you should have 255/35-18 in the back and 225/40-18 up front. So the fronts are correct, but the backs should be slightly wider. Running 245s in back won't harm anything (it will actually very slightly reduce understeer), I would still take it back and request they do it correctly.
