17.5 x 8.5 inner tubes

[brien]

Ok...so I have replaced my widow maker rims with 17.5" rims.

Coker tire tells me I can use these inner tubes with their 17.5 x 8.5 Bias ply but they have offset valves.

Does anyone else know of any other sources for a 17.5 inner tube?

Why? Those are tubeless wheels. Shouldn't need tubes. The valve installs in the rim itself. Stu
