Gazzer996 Posted November 20, 2012 Share Hi Guys, I've got a Momsen, with 29 Crest wheels, and have had endless tyre issues, namely them jumping off the rim, I have tried new rim tape, different tyre sealant, and different types of tyres (6 tyres on the back rim) 2 on the front, Have also tried different pressures from hard to soft, same result,most recently the tyre popped off the rim while i was inflating it (pressure on the gauge 2,8) I have tried the following tyres, Continental (standard on the bike); Maxxis UST, and now hutchinson. Any ideas as to why im having all these issues?Am trying to go to tubes now, and see if i still have the problems, ThanksGareth Link to comment Share on other sites More sharing options...
Gazzer996 Posted November 20, 2012 Share was pumping to 2.8 for road use, not offroad. Link to comment Share on other sites More sharing options...
Bianchi Posted November 20, 2012 Share What width is your rim?I've heard about some guys having issues with rims that aren't wide enough for the tyres.It's the only plausible explanation for the tyre popping off when you're inflating it (since there's no sidewards pressure on it from cornering, etc).

SaKiwi Posted November 20, 2012 Share What is your weight? Crest has a weight limit. Link to comment Share on other sites More sharing options...

dirtrider Posted November 20, 2012 Share Bought a pair of Botragers from the Solomons bargain bin . Popped them onto Shimano rims with a bit of Insulation tape for good meassure . Pump them to 4 bar with compressor . Took a spin around the block , deflated and added plenty of Stans . Up to 4 bar again , did the 94.7 and this morning had to let air out for my offroad ride . Sound like you rims . Link to comment Share on other sites More sharing options...
dee_biker Posted November 20, 2012 Share I have the same bike, same rims, 2.4 tyre (as wide as they come). I don't have any issues, and throw them around quite a bit. Sounds to me like a faulty rim or tyre. Link to comment Share on other sites More sharing options...
kennyg Posted November 20, 2012 Share i had a set of crest where the was a flattening of the bead holder that meant no tyre could stay on the rim... The first time it happened was at 2.8 bar too, and I needed new pants, as I had just started walking away and the tyre slipped off with a bang.

Rapunzel Posted November 21, 2012 Share same problems with crest rims after inflating a new tire to 3 bar (to assist the tire to seat properly). Now when putting a new tire on, I just inflate to about 2 bar and leave it to settle in on it's own which takes about 10min. Haven't subsequently tried pumping to 3 bar but I think that if the beading is properly seated on the rim the chances of it blowing off again are slim to none.

EVOBIKES ONLINE STORE Posted November 21, 2012 Share Get GEAX - problem solved. Ramrod 1 Link to comment Share on other sites More sharing options...
NINER_boy Posted November 21, 2012 Share Get GEAX - problem solved. GEAX doesn't fit on Stans. You can get them on, and in the process damage your rim, but you will need a scissor to get them off! Ride Stan's rims ONLY, and no tyre issues (other than Geax not fitting).ContiBontragerVredensteinSchwalbe, these fit the best! Link to comment Share on other sites More sharing options...
EVOBIKES ONLINE STORE Posted November 21, 2012 Share Uhmm - nope you are wrong... And read the OP's post -this specific set of rims cause 3 different makes of tyres to pop off... GEAX will be a TIGHTER fit therefore he won't have these issues. Link to comment Share on other sites More sharing options...
