stpauls Report post Posted February 21, 2015 (edited) Around 2010 there were many reports of IRC rear tubeless tyres, when inflated to 3-4 pounds, going flat as soon as the bike hit a small step or a root. Many people put this down to the tyre bead being too loose, so the tyre would loose the airtight seal when it hit an obstacle. I understand that this problem still existed a few years later. Have IRC fixed this problem yet? Edited February 21, 2015 by stpauls Quote Share this post Link to post Share on other sites
breagh Report post Posted February 21, 2015 Fitted one a few months back went flat at next two trials. Don't think they like the later rims. Quote Share this post Link to post Share on other sites

the addict Report post Posted February 21, 2015 Don't bother unless it's a old rim !! Spot on that, the new 4rt rims on the standard bike wont keep them inflated, mine came off the rim just riding around, X Lights now with no probs, shame. Quote Share this post Link to post Share on other sites
