255 for the front does sound to wide, and I personally would have narrower tyres on the front it will improve the handeling. Standard I believe is 225 when I get mine I will run 225 on the front but up to 255 on the rear for the mean wide look from behind.

yes 255 is ridiculous, it has no advantages, and apart from catching on arches vertically will needlessly restrict the steering lock for parking (or for catching slides....). Sagaris has different inner arch design completely to cope with this size.

Widest you can get away with if sticking to R888's with their vertical 'shoulders' is 235 and that still has some minor clearance issues. Also the wheel size should be 8" (or 8.5" max) on fronts, 8.5 - 9" on rear. smile

Tailslide is, as usual spot on.
The R888s have a very square shoulder and will definitely rub the front wheel arches. I have R888s fitted to my Tuscan and the 255s initialy rubbed on the rear arches prior to raising the ride height and stiffening the shock absorbers slightly. On the front the best compromise is to fit 225 section tyres, if you select 40 ratio rather than 35 this will keep the rolling radius virtualy the same as the 255s. The 40 ratio do not seem to tramline or hunt cambers to the same degree as the 35s and the higher ratio also helps to calm the steering responce as well. As tailslide stated,the 225s need to be fitted idealy to an 8.0" wheel as they are too narrow to fit the standard 8.5" front spider. It may be you could squeeze a 235 section on the standard rim but whether they would give sufficeint arch clearance I am unsure.
What I can say with confidence is that the r888s are fantastic and definitely worth the hassle and expence involved. The grip and traction the provide in dry and even damp conditions are in a different league to normal road tyres, just dont push too hard in the wet !
