Recommended Tire Pressure
Got some BFG ATs installed several months (E rated with max 80 psi capacity) on my '10 factory 18" rims and was wondering what anyone with a similar set up puts in their tires for air pressure. Raised them from 40-45 last night and notice a stiffer ride which I don't mind.

I failed to mention that in my original posting. I don't know what he set them at when they were mounted. What a various amount of opinions on the subject after I searched online. Some set the front higher than the back, some do the opposite, some say anything over 50 psi is silly unless you're hauling big loads but lots of folks recommend at least 50 psi because running a tire designed for up to 80 psi could be damaging to the sidewall. I'm going to try 50 psi for my upcoming trip and see.

This isn't true. I had mine mounted at Tire Rack and the front right was 58, the front left was 55, the right rear was 50 and the left rear was 52. They just pump air into them and send you on your way.

OK, obviously a monkey did your tires. I was going under the "assumption" that a professional that took pride in his work did a good job on his. Not trying to sound like an a$$ here, but it's a damned shame when you have to go behind every fricken thing that you pay for just to make sure all is well.

My 2010 KR has Michlein's LTX; has max pressure listed on the sidewall at 44 PSI. Truck came to me with 42 PSI, each wheel. Seems to ride OK; but have no idea how much belongs in there. Kind of curious as to why one tire(above) max pressure is 80PSI and mine is almost half that.

I'm running mine right at 50 psi for fuel economy. I run heavy equiptment for a living so the "stiffer" ride doesn't phase me at all. Hopefully these piece of crap P-275/65-18 GS-A's wear out soon. I'm planning on replacing them ASAP, like before the end of Sept. for a real tire. My driveway is blacktop millings and the tread likes to throw little rocks up into my wheelwells for a mile after I leave the house.

If you look on your driver's side door jam, the "Factory Recommended" pressure is listed there (Working at Discount Tire aka America's Tire Co. was my second job ever). For my '10 FX4 Screw, it's recommended to be at 35 psi COLD. I personally run 40 psi COLD, as I want better fuel economy (After tracking mileage, I gained between 1 to 2 mpg which is a 5 to 10% improvement) and it shouldn't wear the middle of the tread that much faster than the shoulders (but the middle will wear a little faster at that pressure). Just a minder, the Factory Recommended settings are usually a compromise between ride quality, load capacity/handling, and fuel economy. If you up the pressure, your ride will become more harsh, but you will gain fuel economy and load handling. It's almost like in NASA: there's faster, better, and cheaper. You can have any two.
