I just got a set of 37x12.5R17 put on my Mojave. They are great! What pressures are people running these at? I'm at 36 PSI now but can't really do a chalk test too easily with all the snow.

I don't have these same tires but have been running 37's for a few months now and I'm down at 32psi for even tread wear.

I'm running 30psi front and 25psi rear.

All the pressures are great but I find that everyone's mileage will vary, best to just chalk em and find out what pressure you should be running yourself.

Are you running a full sized spare? If so how did it fit? Any mods needed to get it to fit?

These are -12mm offset but they also sell a 12mm offset which would be about 1 inch closer to the fender.
