Is anyone running tubeless tires? What kind of air pressure are you running? It's all about feel mostly and the terrain. I weigh about 150 fully dressed and usually run about 30psi
I'm 185 and run 32 PSI.

| Has anyone tried Mibros? I weigh about 160 with my gear and I run 35 psi on a smooth trail. If it gets rougher I add some air to avoid pinch flatting. This is with tubes though. |

| I just got a set of mountain king 2.2 tires and they are worth every last cent. The best off road tire I have ever bought. They do ride alittle slow. As far as climbing and being in the mud, awesome. |

| I'm (cough, cough) more than a shade over 200 and I run < 30 lbs in my 29x2.3-2.4 tires and 35 in my 29x2.1s. That's with tubes. I get maybe one or two pinch flats a year at worst, but the traction is great. |

| I'm around 175 i run close to 40psi on my tubeless system, if i run into major traction issues then i'll do the usual bleed off on the trail. On my park bike i run atleast 65psi. Overall on both bikes if the tires are too low i notice alot of rolling resistance, this maybe the tires but i'm not sure. I'm looking at trying some new tires for my MTB, just waiting to see which one's are getting all the rage, still seems it the nevegals. |

I really like the IRC trailbear in both 2.25, and 2.5 There great except a little on the heavy side. I have some Exiwolf's on my 29'r which I am also fond of. I'm gonna try out some IRC Mythos to lighten things up a little for race season.
Anyone have an opinion about using a mythos front in the rear? I wonder how that would work out. Recommended? Not?

I have heard of people using the front tire on the rear for more speed, but I haven't tried it myself. It's funny that you mentioned it because I was wanting to try it yesterday, but I was running too late to switch tires. I'll try it whenever it dries out and let you know. |

I've done it and in the summers dry conditions it works pretty good.
As good as the new schwalbe's are working I might actually go up to 40 or 42 PSI for even lower rolling resistance. I can see how lower pressure helps with traction but if the rolling resistance goes up due to low pressure are you really going faster???? |

I know someone who has taken that theory to the extreme Rico. I was test riding a guy's bike and he had 60 psi in each tire. If the course was super smooth you could run very high pressures, but the tires didn't grip good enough for me. I believe the argument is the added traction provided by the lower pressures outweigh the added rolling resistance. I think it all depends on what course you're riding. |

Think of it like dialing in suspension. If its too stiff, you're bouncing around and not getting the benefits of the suspension. Too low a pressure, its a cushy ride but you waste energy and bottom out. I've found, for me, 30-35 psi (depending on tire, course etc) works best. Any higher pressure the tire is bouncing off everything (which is especially awesome in corners), any less, I slam the rim or pop the bead.
The tread pattern has more of an impact on rolling resistance than psi. A Maxxis Ignitor just isnt going to roll as fast as a Larson TT. In other words, like the suspension, the right tool for the job works better everytime rather than trying to over compensate. |

Put in 25 miles today with 35 psi down from 40 and it handled the same but could definitly feel the lower PSI or my legs just sucked from playing tennis for 2 hours with my sister. haven't played tennis for 15 years but still had some great games and actually beat her a few times and she plays all the time.
Overall I thought my cheapo IRC mythos rocked,which they did but these schwalbe's truly rock in SC terrain, which is similear to KY besides the few sandy spots in the turns. |

I may not have the years of experience of some of you but I have been through several sets of tires. IMO, the best all around tire would be the Specialized Enduro Sport from around 2002-2004. They don't make this design anymore but I LOVED it.
Durable, hooked up well, rolled smoothly and carried my big butt over anything I was willing to attemp. They handled surprisingly well in loose stuff also.
If they were still around I'd be putting them on my rides today.

| The South Carolina trails sounds like the Caney Loop trail at Cave Run during the summer. We have sand pits in curves that will cause crashes even if you know they're there. Are the Schwalbes' wearing fast? I know you were concered about that earlier. |

I put in about 60 miles on them and they show very little signs of wear so far. Once I put in some miles here in KY on some rough ground with rocks I'll be able to tell a diffrence. |

I run the wtb weirwolf 29x2.55 and the exiwolf 2.3 on a rigid two niner it is a good setup for me I go for about 200lbs. I run the tires pretty flat also, so fetz has something to do in the truing dept.

| I'm a big fan of the Weir (f) /exi (r) combo. Trailbear are an excellent am/fr aggressive tire. Old school firexc can't be beat. |
