    Do single ply tires have a place?

    I was riding some new trail in so cal today, and botching most of it since it was all new to me and I managed to pop my rear tire. I'm pretty sure I knew exactly when it happened, which was on a very small rocky edge I came down on and heard a pop/snap sound like when you kick a rock in your tire. I was running 45 psi.

    Sure enough, a minute later I was down in the first turn.

    I'm running 2.35 minion DHF/DHR which are single ply tires, with normal inner tubes. My LBS convinced me to go this route based on the fact that I do some light climbing, and the single ply 2.35's are way lighter. Sure they're lighter, but can they actually hold up for light DH use? I'm 175lbs and ride a Foes Fly. I need more traction but I'm afraid to drop pressure for fear of MORE flats.

    They are great for XC... not so much for DH or FR. Even further, i'd question them on a serious AM bike. My favorite was to go is to run UST tires. even if your are still running tubes. thick sidewall, but not as stiff as the DH casing ones. They are about as heavy as the DH casing ones if I remember correctly.

    get yourself some Specialized Pin'it 2.5 umma gummys.. never look back (btw I ran them on my foes when I had it.)

    sure they do. It all depends on what kind of trails you ride. On most trails out here in the PNW there are hardly any rocks - i could easily get away with single ply front and rear.
    Since I'm too lazy to change tires for the occasional rockgarden DH trail, I ride single ply front, dual ply rear (both minion 2.5" - had to buy the front tire in germany, since maxxis doesn't sell 2.5 inch single ply tires in the US for some reason).

    Haven't had a flat with that setup since 06.

    agreed on that set up. a lot of people do that out here in rocky Colorado as well.

    I can't help but wonder if its something I'm doing wrong, because I didn't even have much speed when it happened.

    Obviously I'm not about to drop 60lbs so I can ride without flats, so what is my best bet for riding the rocky california stuff and still staying light?

    The problem is the stuff is just so loose you almost have to run a 2.7 front at least, I wasn't hooking up at all with my skinny tires.

    i would just go with some dual ply tires. They are heavier, but you won't get any flats. thats for sure.

    if you want bigger and more bad a$$ tires, i've said it before and i'll say it again. Specialized Pin'it 2.5 umma gummy tires. Ran tubelss. say goodbye to pinch flats, and say hello to ungodly traction, that outlasts minons substantially.

    yeah 1 ply...but at 45 pounds I think it was just the one in a thousand shot....keep riding them....if you continue to have problems (I don't think likely) then switch

    Do DH tubes do anything but weigh you down and prevent every 9th thorn from puncturing? Seems like marketing...

    Single's are OK on the front, no luck with them on back though. I run the same setup as tacabuya, single front and dual rear but my rear is a tubeless version. That keeps the weight reasonable and minimizes pinchflats. I weigh approx. 185 and am able to run 35-40 lbs. in back no problem.

    I've got seperate wheelsets for XC and DH and run both tubeless. The XC set has single ply 2.35 Kenda Nevegals, never pinch flat anymore. When I was running tubes I was using 1.9-2.2 width tubes and it would pinch flat regularly unless I ran them at around 45 psi. At 45 they were bulletproof though, yeah, sounds like a fluke to me.

    DH tubes are alot thicker, I ran them for a while and they never pinch flatted, even when running at 20 psi or lower. They are really really heavy though!

    they keep you from getting pinch flatted as easily since the tube is thicker than standard. this is good for places with rockgardens, or as we say in the good old USA, "rock shacks." like, "imma shred through this rock shack right quick little chillun baby."

    Funny, I seem to have the worst luck with the heavier DH tubes.
    I have been using specialized AM tubes with good results. I run a Panaracer Fire FR singleply on the rear and it holds up well and flats rarely at 40psi. I have been running doubly ply Maxxis Mobster 2.7's on the front but just cause they were cheap and sticky.


    I met a guy on the trail who had a a big slash on his rear tire running tubeless with slime of some kind. He didn't have a spare tube and he only had a compressed air cartridge which promptly ran out because the tire wouldn't seal. I only had a schrader tube and his rim could only use a presta tube. He was SOL and had to walk his bike a long way back to the trailhead.
    So always carry a spare tube and a hand pump when running tubeless!

    I have popped so many single ply rears even with DH tubes. I recently went to DHR 2.5 rear and DHF 2.7 front, with DH tubes and they will never pop

    Yes, a DH tube weighs as much as a house, and a decent XC tube weighs about 150g.

    I've been trying to find a way out of this compromise as well since the trails that have gnarly downhills that are likely to knock your tires up a bit are the ones that have huge climbs at the start.

    Is complete UST the answer?
    I was thinking of a bombproof wheelset that would still be quite light (including tires). Thought about Mavic 819's or Stans Flows infront with 823's in the back on Hopes and go all tubeless. 2.5 front and 2.3 rear. The only tubeless tires that I can think of that are proven the michelins which are expensive and hard to get here and the Maxxis minion UST's which are also expensive and weigh a ton!

    Mavic 823 is pretty tough, not the lightest, but not as heavy as some suggest with the eyelets. I've run 823's for a while now & they are still good & straight.

    I'm toying with going for 819's, they are circa 510g with the eyelets (weighed them up myself) so offer a good weight saving over the 823. I'm pretty smooth so they should hold up well.

    You may struggle with a 2.5 on an 819 rim, its way too wide. 2.35" is alright though.

    Interesting about the Michelins - you are aware that DH16 2.2"s are nearly 200g's heavier than a 2.35" Maxxis UST? They don't seat anywhere near as well as Maxxis either.

    I run single ply Maxxis Minions on my AM bike out here in the sharp rocks of Arizona with basically no problems other than the occasional burping. I run them converted to tubeless using Stans, so even if they do puncture or tear, they seal back up right away.

    I gave up on tubes on all my bikes last year, they are just a pain in the a$$ with all the rocks, at 1 point I had 10 flats in 1 week. Since going tubless I have had 1 flat in a year on a total of 4 bikes.

    I've been having good luck running single ply Maxxis ADvantages in 2.4 setup tubeless. I've torn one sidewall in a freak incident but otherwise they have been fine. The 60a durometer is a nice balance between traction and rolling/wear resistance. It's pretty darn rocky here in UT so tires tear up fast when they're not up to the job. Where I was blowing out Kendas constantly, the ADvantages are serving me well for days of long climbs mixed with DH style descents.

    Err sweet intense by the way.

    how tall are the advantage compared to minion 3c,i did try a minion 2.35 but just to narrow and skitery and the 3c just to heavy,i do know that the 3c minion is taller than my buds high roller.

    i did have maxxis dh tubes but just so heavy so i have put maxxis freeride tubes in and 40 psi which is helping the rolling resistance just the tyres are killing me on the ups.

    Better than the TimberWolf is a tough call because other than the weight the T-Wolf is awesome. The Dissent is 2nd by a tad, im using the Kevlar with DH tubes at 24-26psi depending on conditions. Never had a problem with them folding under my 185lb weight. I also tried the Prowler & that tire slid all over the place in the loose like being on marbles but was decent in the moist giving a little slide then hook up.

    I ran a Timberwolf at Pacifica today regular tube at alittle over 30psi in the back, no pinchflats .

    Everytime I put one up front it washes constantly, sucks in the wet balls in mud.
    In the back it just sounds like a tank tread!

    I weigh 215 & run single ply tires with Kenda medium duty 1.2mil thick tubes. Run my 2.4 / 2.25 tires @ 32-40 psi on a minimum 28mm rim. Run a standard tube (less than .9mil), rim less than 28mm or pressure below 30 and it's pinch flat city. For DH I run DH tubes 2.0mil with 2 ply tires - ran single ply tires & DH tubes but it is hit n' miss for pinch flatting.

    I run 2.35 single ply mobsters on the slopestyle/slalom bike.

    I think it brakes and climbs well and corners very well. I am timid and these things gave confidence. My bike came with OEM ADvantage which have a wire bead and I wonder if they have the 60a rubber or a harder OEM rubber like 70a. I only question this since I got a new one to replace one which I cut.

    The sidewalls are thin but this is a known factor going in. My current heavy DH tire favorite is the Specialied Pinn'it. I live in dry, dusty, rocky, hard pack SoCal where the "hard pack" is so hard it is really more like light tan asphault. The ADvantage is my current fav for AM lighter weight setup.
