Exclamation BFG All-Terrain 265/70/17 E Load Pressure?

Bought a set of BFG T/A KO's 265/70/17's. Tire shop accidentally gave me E-load (10-ply) instead of C-Load (6-ply). There's about a $20 per tire difference, so I'm probably going to keep these. I have been running pressures anywhere between 45-50 psi, but still can't determine where I should be at. Will the higher pressures "spike" my TPMS?

Have you noticed mpg drop with those heavy tires? I have D rated tires and I keep them at 45 which is good for highway on MTR's, the noise is less noticeable.

Mileage maybe dropped 2MPG city. I haven't taken it on the highway yet. I guess I'm running about 18lbs per wheel heavier than the stock GY's. The E-loads are 8lbs heavier than the C-loads.

I would not run over 45 max. If you do your jeep will ride like total crap because its not heavy enough for the max 80 psi that trucks with load range E tires use.

Re: BFG All-Terrain 265/70/17 E Load Pressure?

The best thing to do would be to return to the tire shop and get them to put the right ones on. You cannot really benefit from the durability/load/heavy duty stats of the 10 - ply tires and you have the extra weight and stiffness to deal with. But if you are keeping them I still wouldn't go above 40 to 45psi.

I run the E-load as well, I have had no tire pressure sensor issues or spikes. Had my tire pressure sensors recalibrated as well at the dealer.
I think the tire is rated for 40 psi.

Re: BFG All-Terrain 265/70/17 E Load Pressure?

There is nothing wrong with using a Load E tire on a WK, The only problem you will have is the ride will be harsher. I plan to get BFG AT KO 265/65/17 for my jeep soon because it is closest to stock size that fits in the all terrain besides the 245/70/17. Both tires for some reason are only offered in load range E but yet there is not one single HD pickup truck that uses the 265/65/17 as a tire. The 245/70/17 is used alot on dodge and chevy but not the other size so why the hell is it loaf E who knows.

All Load range E tires are rated for 80 PSI max (i work at a big tire shop so ive seen them all) but in a WK i would not run over 40 psi. 35 psi would be fine too.

Re: BFG All-Terrain 265/70/17 E Load Pressure?

Thanks NHWK05! It's comforting to hear some expertise input. I'm keeping an eye for contact on the edges and 40 seems to be good so far. I'm trying 44 on the front to compensate for the Hemi engine weight and getting full width contact. Is this a good idea or not?

Re: BFG All-Terrain 265/70/17 E Load Pressure?

You can do that if you want but you should not have to. Stock WK Hemi tire pressure is 35psi and with the added strength of a 10ply tire 35psi should be more then enough. The only benefit of running 40 to 45psi would be tread wear. being an E load tire rated to run 80 psi they should last a little longer at 45 psi then 35.

Most guys with 3/4 ton trucks dont even know that they are supposed to be 60psi front 80 psi rear.

Re: BFG All-Terrain 265/70/17 E Load Pressure?

C load rage is what ever your manufacturer recommends for pressure on the door sticker. 35 psi will be fine.
