180/190

Col996s · 30-Aug-2009, 12:17

Thanks guys.

My front tyre has plenty of life left in it. I assume it's quite acceptable to mix manufactures, front and rear.

not usually mate, tyres are designed to work as a pair

you could mix tyres from the same brand ie diablo front and a corsa rear but its usually a big nono to fit say a pirelli front and a bridgestone rear, one companys idea of a 180/55 profile is different to anothers as is the tread pattern

on my 916 i found a 180/55 was better than a 190/50 for fast road/track riding

Agree with the not mixing - have done it & regretted it....

Also check you have clearance for a 190-55 as they can foul the exhaust

Col, as I said, 5.5" rear wheel = 180/55 ZR17, 6" rear wheel = 190/50 ZR17.

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

Its marked on your wheel Col, in one of the 5 spokes.

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.
