I am running 50 psi. I have 33" tires and the guys at the shop say there is no way they would run 30. It makes for a better ride but the tires wont last as long. My truck doesnt ride rough either and I am running nitrogen.

 

Had my pressure light and message come on today and I was wrong, I run 50psi all around

 

275x55r20 Goodyear LS2s. Junk tires. Probably the worst I've ever had.

Around town I have 30 front and 28 rear. If I'm going on a long trip I use 38/36. If I'm towing I put 42/42 in it.

They feather something fierce. They squeal if you have anything less than 42psi in them. The traction is pathetic.

 

I run 30F/28R in mine.

I had the dealer reprogram the TPMS so that they don't trigger as easily. This can be done with a Tech 2.

 

I agree 100%.... I really wish GM would go with a different tire.... they use the LS Series tire for way too many vehicles.

 

35 here in everything I run unless I need to run more air for towing. I never run 50 as that's the MAX cold pressure the tire should be put at. No reason to run the tire at it's maximum pressure all the time.

 

30-32 for me. i have 43,000 miles on them and will try to make them last another 10,000. this is the longest any tires ever lasted with me driving!!

 

80psi is the max for any tire that I have seen, most require you dont fill past 40 psi to seat the beads. The maximum pressure for my tires is 80 and I would bet 80 for yours too.

 

80 psi? That thing should ride like poo. It aint real bumpy?

 

It probably would be but I run 50psi and the ride isnt harsh
