    bad luck or bad technique?

    Todays ride went alright despite the fact that I had a rear tire blowout on a drop of moderate size, about 4-5 feet. The kicker is that I blew the rear tube the day before doing something similar...now after todays ride, the rear tube seems to be holding up after I replaced it, but now the front tire is gradually loosing air...I'm (was) running a hair over 32ish psi in both tires... Should I increase psi, or should I invest in some heavy duty tubes? Or am I just having really bad luck with my tires? 210 /w gear.

    Seems like a tire problem rather than tube. I'm 235lbs and run XC tubes now with no problems so far. And generally I run around 30-35psi. I used to run lower psi w/ DH tubes and never flatted really, but dented my new wheels so F-it, going w/ more pressure from now on.

    any recommendations for tubes? I was using some cheesy bontrager standard presta. I was taking a look at the maxxis downhill tubes http://www.jensonusa.com/store/produ...a+Dh+Tube.aspx . They seem nice and overbuilt for the purpose.

    tires are maxxix minnions 2.35s. They are brand new, I don't see how they could be a problem?

    i'm 240ish -

    i run kenda 2.3-2.4 XC style tubes in 2.5(folding beed kenda blue groove) and 2.35(folding beed kenda nevegal) and pump up to 45-50psi. which is really high and most people hate it - but i've gotten used to it and it works out pretty well - most of the time - still blow tires every now and again. and i don't have to ride wet roots.

    If you're hitting drops and riding downhill at your weight I'd say at least a 2.5.
    But I really have no idea man, 2.35's seem like they'd be okay. Maybe it is a tube deal, but I wouldn't see why. Try a DH tube and see if you're problem is fixed.

    Maxxis 2.35 are single-ply's, that could be the problem

    The IRC DH tubes are possibly the thickest you can get, kinda like a moto tube in thickness. Panaracer DH tubes are a happy medium on weight & thickness. I have flatted both using Maxxis folding bead tires, but it was from hitting something wrong, getting off line. Adjust tire pressure for different conditions. Local trails i can get away with 24 front & 25-26 rear, places like Dville pump them up to 32 front 34-36 rear.
