Will these tires fit?
« on: March 17, 2015, 10:53:36 AM »
 I have a set of Yamaha wheels I want to use. I'm looking at the Shinko 705 tires; sorta dual sporty type.

 The wheels are, best I can measure, 2.75" wide rear (19") and 2.50" wide front (18").

I can find the front tire in a 110/80-19. The rear is listed as a 4.10-18 or a 120/80-18 (essentially the same, right?).
Would the Shinko 705's work, or would they be a bit too wide for the rims?
Would those sizes be too much of a squeeze?

I was measuring outside to outside with a tape measure. Using my calipers and measuring to the "witness mark" of the old bead on the inside of the wheel beads, I get ~2.10" for the front and ~2.5" for the rear. The slightly larger tires I listed above ought to work then, huh?

I am currently running a Shinko 705 110/80 19 with a 2.15 rim on the front of my FT500, but the 705 120/80 18 rear tire was not rated for tubeless use, IIRC, so I ended up using a more aggressive tread Shinko 700 130/80 18 on the rear 2.5 rim.
Don't fix it if it ain't broke!

 Do you have any pictures of how they look on the bike?

 I'm now considering the Avon Distanzia. I can get the front in a 100/90-19, which is pretty much the stock tire size for the XS650.

 The rear is available in 110/80-18 and 120/80-18. Which would be the best fit for the ~2.5" rear rim?

The Ascot stock tire sizes were 3.50-19 (2.15 rim), 4.25-18 (2.5 rim).
I would have preferred a 120 rear over the 130 I ended up with, but it seems to work well as a dual purpose tire.

I'd go with a 110 front and a 120 rear. Are these spoked wheels or mags?
