Home Forums Gear Hunting Trucks and Four-Wheel Drives BFG AT KO2 tire pressures?

With the 265/65/18 Hankook ATMs I have on my truck now, 5 pounds less than the 50 PSI max listed on the sidewall data, in cool/cold weather. Summertime, 8 pounds less.

Had a set of BFG AT KOs on a half ton 4x4 back in 2002. Ran 'em at whatever the max sidewall pressure was. At maybe 50K miles and running the truck hard on a four lane, one front tire literally exploded. Ain't owned a BFG since. FWIW, they weren't worth all that much in deep mud or snow and that truck saw plenty of both.

In my 63 chevy i run 25 lbs.

In my 2015 f150 i run 40 but air them up when pulling a trailer.

Preach!

Amen!

I've had good service from Cooper AT3s on my previous truck and them ol' Hancooks on my current ride They replaced the useless Goodyears that came on it new..

My first 4x4 was an '80 K10 Chebbie short box. Forget WTH they were called back then, but put a new set of fairly wide Firestone "off road" gums on it. Buddy had a set of Wranglers with a similar tread style on his '81. Both sets of tires shared the same problem: Hit an inch of standing water at speed and it was white knuckle time,

Tire makers eventually figured out it was a good idea to design a tread that actually allowed water to escape, so the sumbeeches didn't hydro plane..

Sorry,

Have been out of town.

The tires are BFG AT KO2, LT305/65R18 124/121R on a Silverado 1500 Trail Boss

5 pounds under max pressure on the sidewall.

Not BFG's but Brigstones on the wife's new SUV. 20's and H rated and it rides terrible at the door jam recommended 35 psi. H's are 134 mph rated tires and why do I need that on something that isn't going even half of that speed during its lifetime? I run Michlen P rated 20's on my truck and at 35 psi they ride just fine. S rated 19" Michelin tires on the same model older SUV and they ride way better than those Brigstone H's. I might be wrong, but aren't people looking for a smoother, quieter ride from their new car? I miss those 15, 16, 17 and 18" wheels with the more flexible tire sidewalls.

Update: I talked with a tire guy today and he said that I could reduce the tire pressure down to around 32 psi for a better ride, but he said that he wouldn't ever drop it lower than 30 psi.

They are about 38 PSI now. Might bump it up based on the responses. Just want to maximize the tread life as they are not cheap.

Do the chalk test

^^^^

That. Let the tire tell you how low it will let you run in pressure, for ride quality with and E rated and a 1/2 ton. Otherwise, you’ll be running it too stiff for a good ride or the suspension to like it, or too soft for good wear. ....at least that’s been best since a tire bud had me doing it for when I put bigger/stiffer tires on my lighter Toyotas and such.

44 psi on a 2014 Tundra

On our 2012 Tundra with 213,000+ miles on the odometer, I am on my third set. FWIW. I have been running them at 40 psi on the highway, but air them up to 50 when we go somewhere off road with a lot of rocks. I have never had a problem, but my wife has ruined two over the years while driving on rough backcountry "roads" that are not regularly maintained.

Jeep xj and cj.....31 x 10.50s.
35 on street. 15 -20 wheeeling ( reg 8 inch rims ).
Reg BFG AT and KO.....even wear....lucky to het 30k out of a set.

Ride good. Did ok offroad to 50%.

Switched to Goodyear MTR. Sucked on wet pavement, but better everywhere else. 40k amd no flats. Cost more.

Got cheap Mastercraft going on the Jeep this week
