Default Tire pressure for Dodge Ram?

I recently bought a set of BF Goodrich A/T's for my 1997 (1500) Dodge Ram. The tire size is LT265/75R-16.

The people where I bought the tires (Discount Tires) said 35 PSI is the correct pressure for normal driving on pavement/hihghway. This seems low to me.

Any thoughts or recommendations? (BTW, I do air them down when going off-road)

Thanks
Jason

That 35PSI seems about right. When in doubt, consult the door dataplate.

yeah 35 is the standard pressure we set at discount tire. you can have them put any pressure you want. 35 is correct, however it is a little too soft for me so i run 40psi. i have the same tire size as well.

standard pressure Discount puts in
32psi in cars (stock size)
35psi in trucks (stock size)

i noticed you are running LTs so they are obviously heavier due to the ply number. i would air them up so they arent soft

I do 36 PSI when the tires are cold. That way they warm up to 40 PSI.

people running with 50 PSI are pusing it pretty far.

I know that my wife's grand cherokee had a monitoring system and it went crazy when I used the wrong side of the gauge to fill the tires. Pumped them to 48 PSI.

50 PSI + 5600lb truck is not a good mix.

go 36 PSI, max 40 PSI

what you also need to do is understand your Load Range because that will let you know the ply number of the tire. also look at the Max PSI on the tire as well. after you understand these two areas, then you can take a look at if your new tire size your running and see if it is stock or not. if it is stock, the door jam is a good guide, if it is not the tire store should help. will you be carrying heavy loads, towing? if you don't like that heavy of a tire, you can get the P265/75/16 instead of LT.

I would stay under 40 unless towing, gives better traction in rain and usually gives a good wear pattern, if you tow a lot then I would raise the pressure to around 50 if the tires will allow that, I run my M/Ts at 34 and it gives a nice soft ride and they are wearing good for what miles I have put on them.

Well, the guy at Discount tire told me that they are supposed to be at anywhere from 50-85! He said 85 if I was towing. They are at 70 PSI now. I guess I need to drop it WAY down? I have BFG All Terrain 10 ply tires and they are 275-70s
