I meant to be getting Goodyear F1's on the rear tomorrow but I have Bridgestone Potenzas on the front. Is this combination ok?

Im getting the Goodyear's at £80 each.

 

good price but i prefer potenzas all round can get the car round a corner side ways and still get the feel back no bother

 

Do not put different tyres on front/back. I had Potenza's on front and Goodyear Eagles F1 GS-D3's on back for a while and the car handling was a bit scary at times - tramlining, often a floaty unsafe feel on differing cambers. Since I put Goodyear's on front to match the back, the car is so much more assured. Also GSD3's came out well in car mag group test on wet and aquaplaning - Potenza's maybe better in dry. Also best to try and keep similar tread depth all round so whatever are your best tyres, might be cheaper to get two more of the same.
