the addict Posted November 19, 2014 Report Share Posted November 19, 2014 (edited) Recently bought a new IRC rear, went down 4 or five times on Sunday as well as jumping of the rim? I could maybe understand hitting a big step but we rode mainly mud sections and roots. I have since heard there has been a problem with them or some of them, and as these are my preferred tyre has anyone found any tips about keeping them on the rims or preventing them deflating? Thanks Edited November 19, 2014 by the addict Quote Link to comment Share on other sites More sharing options...
the addict Posted November 19, 2014 Author Report Share Posted November 19, 2014 (edited) I've inflated the tyre and its kept 60lbs of pressure in it since Monday, but I'm pretty sure it did this fine when originally fitted.

john.b Posted November 19, 2014 Report Share Posted November 19, 2014 They do not stay on the newer type rims, chuck it and buy a Michelin X lite. Grip just as well as an Irc. Quote Link to comment Share on other sites More sharing options...
steve Posted November 19, 2014 Report Share Posted November 19, 2014 Unfortunately it would seem IRC tyres have problem with certain rims. I love the grip and prefer them in our centre but can't get them to stay up on my Gas Gas. Had the problem a couple of years ago and ended up putting a tube in as couldn't afford to throw a good tyre away. Went onto an XLITE but more money and didn't last that well. Made some enquiries at the dealers and was told IRC had changed the profile so tried another this year - No different. A tel-tale sign is when you fit the tyre it pops on so easy and takes very little pressure to inflate, it doesn't go with a big bang like a Michelin does.

copemech Posted November 20, 2014 Report Share Posted November 20, 2014 Just, keep the 60 in and will be fine! 2 Quote Link to comment Share on other sites More sharing options...
vmeldrew Posted November 20, 2014 Report Share Posted November 20, 2014 Yep I've got one sitting in the garage, been used twice and that was enough, unless you carry a pump around with you. Always seems to go down after a jump or hitting an object quite hard. Funnily enough it was a right bitch to get off the rim though. How they can sell this rubbish I don't know. Has anybody tried to return one? Quote Link to comment Share on other sites More sharing options...
guys Posted November 20, 2014 Report Share Posted November 20, 2014 (edited) The IRCs inner diameter seems to be a bit larger than Michelins. I tried to mount a Michelin on my Bultaco rim and it wouldn't get on the bead seat, no matter how much pressure I applied. Bought a IRC and it popped up the bead seat with no problem. But now the IRC won't stay in it's place, it tends to rotate on the rim although I've used new tire locks.

Has anybody tried to return one? I returned one to BVM (before new management/ownership), they took it back in exchange for a Michelin without any problems. At the end of the day it was "not fit for purpose" which is a real shame as I found they worked really well and seemed to last a little longer than the Michelins.

4stroke Posted November 20, 2014 Report Share Posted November 20, 2014 Just recently gone onto tubeless IRC using a 315r rim and had no problems at all! Running lower pressure than I ever did with the tubed setup. Quote Link to comment Share on other sites More sharing options...
anotherfive Posted November 20, 2014 Report Share Posted November 20, 2014 Same happened to me. Had two wheels one with IRC and the other with X lite. Have ditched the IRC but did like the grip. Could you tape the rim with electricians tape to give it a slightly larger diameter? Quote Link to comment Share on other sites More sharing options...
