Best fix for screw in tire?

[bwringer]

Cheng Shin HiMax can be used with or without tubes -- they are marked "TUBE/TUBELESS".

If you go tubeless (which is preferable) you MIGHT have to modify your wheels to accept the tubeless valve stems. This is NOT difficult to do ... just time consuming, as it involves grinding down the area around the valve stem hole so that a tubeless stem will seat properly and not leak. I've helped do a few over the past few years with excellent results. If you're lucky your bike may already have been converted.

If you don't have the tools, time, or confidence to do it yourself you can probably get the tire shop to do it for you.

Regards,

I never did this modification. I just used a straight metal valve stem with a gasket (supplied with the stem) on both the inside and the outside of the wheel. No grinding was neccessary.

Last summer we had to do some grinding on either Dom or Ryan's (don't remember who switched) wheels ... a gasket wouldn't have worked on these particular wheels because the surface right up to the inside of the hole was sharply tapered. We dremeled out a very nice flat surface for the inside of the valve stem to seat and everything was golden. We also did a VERY VERY thorough job of cleaning and smoothing the inner lips of the each wheel to prevent rim leaks and as far as I know there have been no problems. I forgot to mention this important additional step, but then one would hope that any time a tire is replaced the inner rims would be thoroughly cleaned as a regular part of the job...

The rim will be marked tubeless if is in fact a tubeless rim. Tire shops will not install a tubeless tire on a tube type rim either. I was told they couldn't by law. It's possible they don't want the liability as well but was told that by more than one shop. The year of your bike could be either as they were switched arounr that time period or a few years before. But you may have olde rims from previous stock too.
