I have had this problem in the past. On the standard width sport alloys I started off using Hankook Sport Ventus 102's inexpensive, good grip in wet but would only last about 5,000 miles due to fairly soft compound. Then tried the Ventus 104's and they were better, in fact they lasted twice as long.
I then got talked into trying some Dunlop Sport DSST 01's (runflat spec) had them on the rear for about a year and they wore beyond the wear marks before I noticed.
I then switched to the wider 10" rears and after having alignment checked by Dr Bones I have been running Dunlop SP 8080's which as far as I am aware are designed for use on BMW M3's and Z4's after 6 months or so I still have loads of tread and wear as far as I can see is fairly even. Quite frankly the best tyre I have used for years. They also keep the rear end on track so no more 'drifting' on roundabouts in the wet!!.
In a nutshell try some Dunlop SP8000's or the SP 8080's.
thanks for the input , but i have standard 11" rears.275/35/18,quoted £628 for 2x275/35/18 and 2x 245/45/18 on Pirelli, is that too much??
Got my Dunlop SP 8080's for £250 for the pair - no questions asked if you know what I mean.
can u get me any.......front and rears?
