You have a 5.5" rear wheel.

Regards.

How does one know that their wheel is 5.5"? Is it marked in some way?

I'm pretty sure its cast into one of the spokes Col.

As for mixing tyres, I ride mixed tyres all of the time (always use bridgestone front), and have never had an issue.
I also can't tell the difference between 180 & 190 on the rear. Change the width or profile of the front though and its a whole different ballgame

Done it with several tyres, sometimes works really well.


Sometime doesn't, tends to depend on difference in profile and carcass weight v suspension & geometry settings. Probably though, the single biggest factor in making it work is matching the hot tyre prssures for each tyre type / make - thats the trial & error bit were it gels or goes horribly wrong.

i noticed a real difference on my old 916 which came with a 190/50 fitted,i couldnt get it to drop into the corners like i wanted/expected, fitted a new 180/55 to it and it felt a completely different bike and handled like a dream round cadwell. everyones different but i thought there was hell of a difference

...and if you bung a 200/55 on and zoop ovr a humpback bridge in wales, this'll happen!


incidentally, it hasn't slowed the steering but i'll never get closer than 10mm to the edge - on a 6" wheel it's curved round a bit too much. Not a size i'd normally go for, but 2 x rears and a front D211's for 47 on ebay was too good to resist.....

My rear has had it (underlined by its stepping out on a clumsy downshift in the wet on Sunday), and I'm looking fwd to making the shift from 190/50 to 180/55. It certainly doesn't fall into corners at present.

(I fancied trying the new Rosso Corsa (which replaces the Diablo Corsa III), or maybe the Mich Power Pures, but there's still lots of tread on the front, which is a Diablo Corsa (pre-III). The Corsa III has the same tread pattern as the Corsa, but the Rossa Corsa is different, so unless I elect to chuck a perfectly decent front away I think I need to put a Corsa III on the back, even though it's being replaced. Um, thanks for listening...)

There is a 25 cashback deal on Diablo Rosso corsa's at the mo.

here

http://www.pirelli.co.uk/en_GB/brows...FlyerApril.pdf

I'm gonna get a set for cadwell. Probably 190/50 or (thats what pirelli recommend) just a bit worried that a 190/55 won't clear the exhaust on the 998r, might even stick with a 180/55 as that what's on at the mo, I just can't tell the difference.

Just used a set of Corsa III for a trackday and 4000 plus miles on the road, they are squared off after a long road trip but still life left in them for bimbling about on the road, well impressed.

You certainly are not. Not long ago I posted in another place as follows:

"As an aside, what bone idle sod is in charge of product naming at Pirelli? I'm thinking of some new boots on my 998. I know from changing tyres on the SS last year that the Diablo Rosso was replacing the Diablo. Or at least some dealers say it is; others insist they'll be available in parallel. But the Rosso is newer, ok, must remember that. I go check. Now there's a new tyre, the Rosso Corsa. I thought there was a Diablo Supercorsa SP - there is, aaaaaagh. And of course there's the oh-so-easily distinguished Supercorsa Pro. Is that the 3-compound one? No sir, that'll be the Diablo Corsa. Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaagh.

So in their sports range alone there's a Diablo, a Diablo Rosso, a Diablo Rosso Corsa, a Diablo Supercorsa SP, a Dragon Supercorsa Pro, and a Diablo Corsa III. Simples.

I'm going to switch to Michelin 2CTs just cos I can remember their f***ing name.

Thanks, I feel better now."
