At the moment I've got Continental Contactsport 2 205/50/R17's on all four corners. The back pair are practically new but the fronts are down to (as the tyre guy put it) "about 1,000 miles left, just under 3mm". I've read previous posts about these tyres getting skitish below 3mm and definatley agree. Anyway, even with 15% off I was quoted, like for like,

You can run with the 205/50 on the front and the 225/45 on the rear....I've done and so have many others.

Agree with SkodiRS, I had the same issue when I changed to 225/45/17 Toyos, basically stuck the Toyo's on the back, ran the Conti's on the front till they needed replacing. I didn't encouter any problems.

i'd definitely say don't just put the cacky tires on the rear - it's really tempting as the fronts wear down faster but it's asking for trouble. you'll go round a corner one day and the rears will just *let go*. ideally you rotate them for even wear, but no-one ever actually bothers doing this obviously as it's pure mither.

as long as the same tyres are on either side of each axel it's all good.

Has anyone ever just stuck on 205/45/17s? Much cheaper than 50s.. slightly better acceleration too. Although your speedo will be slightly out.
