    Flat Tires

    Just moved from the mountains to the city about a month ago. I've been riding on the street but it seems that everytime I go out and ride, I'm getting flat tires. Pulled off the knobby tires, got some k-rad's, lined them with an old downhill tube still getting flats. Riding a kona stuff...I'm 210 lbs., am I just to big for street??

    Pump them jokers up. I've got K-Rads (2.3") and I run mine with at least 65 pounds. What kind of flats? Pinch flats? or just debris? I'm only about 165lbs so I'm not stressing them as much but, I've only had one flat. It was a pinch from coming up short on a sharpedged ledge. Also, take the tire off and look for a spoke that may be rubbing or poking through.

    TXhucker has great advice. If you are riding urban and jumping etc, you need some high pressure. I weigh 140 and I roll 40# per tire at a minimum, and that's really on the low side- I should be doing 50-55 for safety's sake. If you are getting thorn holes, try the anti-flat tubes and maybe some tire slime. They are heavy but cut down on flats.

    I used to have a wheel that would always go flat for no reason. Finally I stripped tire and tube off and found a sharp sliver of Aluminum floating around from when I drilled out my presta holes. It was slicing open tubes from the inside! Worth a look maybe.

    You definitely want to pump those suckers up. As mentioned, inspect the inside of the tire and rim for any debris. If you have a rubber rim strip, you may want to use a nice cloth one, or even double up on them.

    I have my DMR Moto Diggers sitting at 90. I've gotten my Hookworms up to 110 before.

    Thanks guys. I'd only been running about 35 lbs. of pressure. I also picked up a massive downhill tube, so hopefully it won't pinch as easy. Broken hub and wheel this weekend, so I guess, I'll start a new thread.

    You could also try picking up a rim that is hard to pinch like a double track or double wide

    Are those rims wider than a normal rim?
