I'm looking to get rid of the runflats on my 135. Finding tyres is proving to be aproblem. The rears are fine 235/35 18 these seem to be availble in all brands, including my prefered choice of michelin ps.The fronts on the other hand are proving to be a little troublesome, 215/40 18. I have looked on the usual places on tinternet but as yet I can only find cheap brands or pirelli. any ideas?
Appologies for another tyre thread, but needs must as they say.

You can get P Zeros, Conti Sport Contact 2s (and 3s) in that size. I run the CSC3s - Very decent tyres.

I need to put runflats back onto my 135i to p/x it. Interested in swapping for my P-Zero Neros?

What you want is 225/40 front and 235/40 rear, works perfectly.

Michelin PS3 or Eagle F1 Asymetric seem popular although Falken etc are available if you are on a budget.

Take a look over at Babybmw.net this has been discussed loads of times.

I just got back from the launch of the Continental Sport Contact 5 and one of the track cars was a 135i.

Unfortunately there were no competitor tyres to compare against directly, but I can tell you the tyre felt good on the vehicle and withstood some epic abuse (think 10 laps of pure drifting without falling apart)

Conti never do it as they believe it's too easy to rig. Instead they provide comparisons with their older products.
