Sensitive to tire pressure

[thstone]

29 front is not too low. Factory spec is 29F/36R. This will result in understeer so some owners increase the front pressure a few pounds (31-32) and lower the rears a few pounds (34-35) to try and balance out the handling a bit. Ultimately, it depends on what you like.

I'd go with weekly. My 18s are a little wobbly and bent on the insides, but seem to hold pressure fine. I still do it weekly. If you are feeling a bit lazy, go to wal mart and get one of those electronically controlled air pumps with the PSI settings. I like to do completely cold readings, so I've always used a bike pump (good workout) but this little thing has been a joy. It turns off when the pressure has been reached, and is very accurate.

edit: also 32/36 is much better than factory specs. Car rotates like you want it to.
