Default Tires

I was watching trials riders on unicycles tonight and they use a 20 X 2-1/2" tire that might make cutesy wheels for a motorbike. Just a thought.

Default Re: Fat tires

Rebuild the rear end or at least spread the original stays. There are extra fat tires I have seen with extra fat rims that would take a custom rear end. The primo set up I think. Surley is offering a fat rim called Large Marge for the Pugsley frame and fork.
The Endomorph tire is 94mm wide (3.7") x 740mm tall (29") on our rims. It’s the highest-volume production bicycle tire on the market at this point. And, at 1260 grams, our 60 tpi tire weighs 300–400 grams less than lower-volume 3"-wide DH tires. Most 3" DH tires hover around 1600 grams.

Pre-war fat tire bikes are the best for this, the 24x3 tire isn't as tall as a 26" tire/wheel combo...just a little smaller, it still gives the appearance of a 26" wheel!

Another option is to build your motormounts offset. I built mine 1 cm off to fit hookworms. I also had to dish the rear wheel , and spread the reart chainstays, and use a long rear axle. Might need wider crank arms or an adapter. But it is doable.

Those Surly wheels and tires would be flipping sweet on a MB. They're pretty expensive though, plus the cost of a frame to clear them.

Default Tires

I need to replace a 26" x 1 3/8" tire and was wondering if I could put a bigger tire on the rim.

I always see tubes coming in sizes that will fit a number of different tires and would like to know if it's the same with tires. The rim is a narrow one for road bikes, but will, say, a mtb tire work on it?
