| No, I stuck with Diablos both 180 and 190. I do recall noticing in the past that certain manafacturers tyres were wider than others for any given width. I think Dunlops were always wider (or appeared so) than others. If the tyre is slightly wider than another make it makes sense that if its profile whether it be a 50 or 55 is accurate then the rolling radius of the tyre will be larger and so nearer to the exhaust.
I spoke to a few people when I had trouble with mine and nobody has heard of this problem before. JPM reckons I must have a short wheelbase 996R! |
