    Tube tires run tubeless on Crossmax ST...

    I know this has probably been covered on here like a thousand times but I just purchased a set of 2011 Crossmax ST wheels. Never run tubeless before. Simple question... can I run my current non tubeless tires (Maxxis Larsen TT 2.35, Maxxis High Roller 2.35) on these rims? And do I need to use sealant of any kind or do these rims work with these tires without it? Any other advice?

    You can run tubes by removing the valve on the wheels and simply mounting the tires and tubes like any other wheel. Attempting to run non-tubeless tires without tubes will require sealant, probably a air compressor to mount them, and may or may not work.

    No I was asking about NOT running tubes.

    Using any standard tire without tubes is a crap shoot. May or may not work.

    The trouble with common sense is it is no longer common

    IMO, stand rims are hands down the best for running tubeless with standard tires. UST rims (like your STs) work better than standard rims, but it's still tricky to get a standard tire tubeless on them and some just don't work. Sealant and a compressor is your best bet and keep your pressure on the high side for a few rides until you get a feel for whether they are likely to burp.

    I've had good success with maxxis and wtb, mixed with schwalbe, and conti haven't been worth the trouble. Many new tires are out with tubeless ready beads though, which work perfectly on ust rims.

    Other advice: Run one of the many "tubleless read" tires out there. Lots of good ones that have reasonable weights. I could never go back to tubes. UST of course work well, but tend to be heavy. Specialized makes some very good tubeless ready. Captains and Purgatory are very nice tires. Just rode some Conti Trail Kings today, and those very nice. 2.4" on front was a huge tire, if you're into that.

    I run Rocket Ron Performance tires (non UST) tubeless on my Crossmax ST. They work much better when new and I use Stan's.
