What kind of tire pressure should I be running with? I've had a couple of flats over the past few rides. When I look at the location of the hole afterwards I see they line up with my spoke positions. The rubber piece is covering the spoke holes. Too much pressure?

if they're lining up with your spoke holes and are on the inside (along the rim strip) portion of your tube, then it maybe time for a new rim strip. The other option is to run 2 rim strips.

Get a cloth rim strip, solved all my spoke flats.
I run around 25 to 30 ish on the front with a 2.35 nevgal xc tubes xc tires, and have yet to get a flat while running the local DH's.
Out back is a little higher(hardtail) from 30 to 35 with some cheap wallmart tire I had laying around and xc tubes again. Just learn to be smooth and avoid the sharp rocks where you can.

By the way I'm 150 and riding a dirtjump bike while keeping up with most everyone on the DH runs, which are super rocky and bumpy as can be. And everyone else seems to laugh at my xc tubes but their the ones getting flats.
