Hey guys, just got a set of bfg's(from 1loudlx here on mud)great tires and great deal.My question is about tire pressure,The place that mounted them put em at 30 and i think thats to low.They kind had a bulge at the bottom.Tire is d rated and can handle 65 but thats gotta like a brick.So what do you guys run your 285's at.Going on road trip sat. morn so any help would be much appre.


thanx

For paved road use I used to run the same size MT/R's between 35-40psi depending upon load.

35 Cold should give you a nice solid ride on the Highway once warm - but as Spress mentioned - it depends on the load you add. I think 30 is too low

I think 30 is low too. I run my MTRs at 40 on the street.

I'd run those at about 35 to 40.

for best mileage on pavement go to the highest pressure you're comfortable with (but not more than max of course) and that won't overly wear the center (have a look and see if the sides still touch the ground). For long freeway drives, I've done 50 or 60 (if loaded) with the MT/Rs.

Here is an interesting thread from 6 months ago about D/E load rated tires.

Tire engineer from Bridgestone calculated 38 psi for my 285/75R16 Revos using the actual axle weights of the 100 and the tire load formulas. I've been running that since with perfect wear and a nice ride.

I would drop BFGoodrich a line and have them calculate the ideal psi for you or at least ask them to send you the load table for your tires (they don't seem to have them up on their website). To do that they'll need your tire info (Model and size) and the crusier's weight data (GVWR and the GAWR for each axle).

Thanx

As always thanks for your help,I just put about 650 miles on my truck this weekend.Ran them at 40 and did fine,think I,ll try 38 dont know if it will really be a diff or not.Also threw a wheel weight about 20 miles into trip so had a little wobble but thats just my luck.

Thanks
