Tyre/Wheel - Can I fit a bigger tyre?

Will a 180 tyre fit on a 6.25" rim,or do you have to go to 190?

It depends ...

Some tyre profiles are more sensitive to rim width than others. Dunlop, for example, says that their 180 slick works fine with up to a 6.25 inch wide rim. In the past, both Michelin and Dunlop have stated that a 5.5 inch wheel is suitable for 160 through 180 tyre widths. Different tyre manufacturers specify different rim widths for their tyres.

In general, you'll expect to use a 190 on a 6.25-in rim.

Whats the best combination for a 190/50 then?Keep the 120/70 or go to a 120/65?

Have you thought of using 190/55's?

Yes mate,i am open to suggestions.I have posted the quandry in the 851/888 section!!

I read somehwere that the new 190/55 gives the same speed of turn in as the 180/55 which would be perfect.

But what front?

I'd stick with the 120/70 front and pair it up with a 190/55 rear.

Had a 120/65 front on my ZX6R, and I didn't like it, just felt like it was going to tip in a little sooner. Couldn't imagine what a 120/60 would be like!

Dunlop also do a 190/60 which I've heard good things about...
