I would shoot for around 30-31 psi hot.

I started out with 34 cold and eventually settled on 31 cold for a slightly better ride. Having 18's all around the sidewall is kind of small so a small change in pressure is noticeable (at least to me).

Thanks All....
It won't get very warm here now for 6 months or so...
Ugh!!
So maybe I'll bring it down to 30 cold??
Just wondering if it will hurt the overall tire life or not?
Anyone have some significant miles on them with the 30 cold PSI?
