What tyre size ?

[juancarlos66]

I have 26 x 1.90 tyres on my bike at the moment, these are the ones it came with. Can I fit a different size (2.0) or do I have to stick with the same ?

Thanks.

Yes you can, with a couple of caveats. Internal rim width will affect the profile. Moving to a 2.0 will be fine but if you're looking at 2.3 and up your rims really need to be 19mm or more to get a good profile on most tyres. The other caveat is that your frame and front fork will be rated to a specific size, any bigger and they could rub and cause wear. What bike is it? Again, a move to 2.0 is unlikely to be a problem, but best to check.
