What is a good tire pressure for rocky singeltrack?. I was running 30lbs, and felt like I was being bounced all over the place. Later on I got a flat. Wasn't sure if it was a pinch flat. Any recommendations? I ride a ridgid Vassago Bannersnatch with 2.1 WTB tires.

35-40 for me. Most of my riding on the 29er is done at the Allegrippis trails so it's not overly rocky.

It depends... 30 sounds a bit high. Might have been a fluke that you got a flat. Sometimes speed and a pinch at the wrong angle are enough to cause a hiss/pop.

I am in MD and typically run high 20's on tubed 29er WTB 2.2 tires and haven't gotten a flat on them yet.

I normally run 25-30 tubed. I get a flat about once every month to every other month. I switch between rigid and a minute29. if you ride rigid on really rocky terrain, seriously consider some nice wide 2.25 to 2.4" tires. I ride 2.1 with my race setups and they feel narrow. size matters.

I run 35 or so with tubes. I rarely get flats.

I find that running in the 30's equates to less traction. Through mud, loose dirt/gravel, etc. it is worth slightly increased flat potential to get grippage. I have tubed Conti mountain kings on one bike and tubeless Schwalbe racing ralph's 2.4F/2.25R on another bike.

OP how much do you weigh? 30lbs of pressure is a lot different if you weigh 150 vs 200 lbs

I would like to hear opinions/suggestions on this as well. I recently added my first 29er hardtail to the fleet. Since I have been riding a 26" wheels with 5" of travel front and rear, this is totally different.

My first ride on the bike yesterday was a bit too harsh for my liking (I could tell the rear tire was too high of pressure but I started purposely high to avoid pinch flats).

I'm 220lbs and will be trying out 37psi tomorrow morning (with tubes for the moment). Thoughts?

I am 220ish, and run mid 20s front, and 30ish rear. Rarely pinch flat. Tires do feel slightly squirmy at times, but I ride full rigid, so every bit of suspension helps!

I'm 190# and haven't had a flat yet on either my tubed HT 29er (1 year) and tubeless DS 29er (3 mos). I never exceed 30 PSI and always run the front lower than the rear.

Thanks for the info. I'll give it a try this weekend.

I've been running about 24 psi on my 2.5" Racing Ralphs, great handling/bump absorption and no flats yet. The only thing is that I get a little tire rub as the rr. tire sags a bit at this pressure. I will probably go down to a 2.3 or 2.4" version soon.

The width of the tires makes a huge difference, a 2.5" 29er can handle 30 lbs of pressure a lot better than a 2.1. Also rider weight and riding style can affect pinch flats as well. I'm 145 lbs and run at least 35 PSI in Kenda Smallblocks, 29 x 2.1 and have not had a pinch flat yet.

If you are looking to run a very low PSI, heavily consider getting wider tires with a tubeless set up. Wide tires are better suited to low PSI, as are tubeless tires or tires set up with Stan's.

what would you guys recommend the tire pressure to be for someone whos 160 for trails/winter commuting

I ride tubeless at 220lbs front is 27psi rear is 25psi
