Tire sizing options...

[joshga]

Hello everybody today I have a question. On my xs400 the tire that is on the front is a 3.0 s18 and the rear is 120-90-16. what size tires could I change to and still fit the wheels? All I need to know is what will fit the wheels... Im already changing fenders and stuff so thats no worry. I know the tire diameter cant be changed but what can be different? any help would be great!

You can fit a 130 on the back if you remove the chain guard and maybe a little shimming with the brake stay arm ( at least last what I had to do). It was what came on my bike when I got it and it was a new tire. I did go back the the stock size because it fits better and weighs less for reduced rotating mass. The front will take up to a 120/90-18. But with bigger heavier tires it will not perform as well as the stock set up. But if you are going for looks then have at it

Are you trying to keep the vintage look or update to newer tire designs. A couple vintage-looking options are the DUNLOP K81 and HEIDENAU K34 and K36.

What I am trying to do is make an enduro... On road off road bike. I want a pretty aggressive tread and pretty fat tire!

If anyone knows of any 17 inch rear spoked wheels for sale with a drum brake that wouldn't be to much hassle to mount up to this bike let me know!
