tyre rubbing exhaust

UNDERSTOOD HOWEVER
THE 190 WAS FITTED AS STD TO THE 996R ON THIS RIM? AND DIDNT RUB THE EXHAUST, SO IS THIS SOME kinda Phenomenon

so what ive found out is...

that tyres have differing profiles(or should i say shapes )dispite what is written on the side of them,
the dunlop 209s that i was running have a profile which runs closer than say a supercorsa.
come to think of it i had a prob b4 when running a 208 and it started rubbing the rear hugger, just the tyre wasnt on there long enough to cause an issue

Martin H did you cahnge tyres when you discovered this

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!

well i cant really make much sense of it, as thinking about it the bostrum rep 998s came with dunlop 208s or were they 207's anyhow the problem exists.

potential soloution of a 16.5 rear rim being considered

had similar problem with tyre not cleraing hugger but that was defo hub positioning....it was at 7 oclock not 4 oclock...just chnaged from 180 to 190 so I'll have a look later, might explain why I'm so slow of the tyres rubbing

Are you running a full 998S exhaust, or 998S downpipes with a different link pipe and cans

Bungi · 14-Jul-2006, 15:09

running a full 50mm Termi system kev

What tyres are you running???? if it is a Dunlop then you will find that it grows when hot and used at speed due to the profile of the tyre & it will rub the exhaust even a 45mm system, try a differant tyre & see how you get on.
