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

[Shazaam!]

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?

[khu996]

Have you thought of using 190/55's?

[Jasper]

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?

[khu996]

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...
