Default 285 65 18 Trail Grapplers!

Stock wranglers wore out at 38k, and couldn't come soon enough. I never liked them...

Just got 285/65 18 Nitto Trail Grapplers installed. No rubbing anywhere, and completely stock suspension and wheels!

What tire pressure have you guys found wears best on 10 ply tires with these trucks?

Went I had 285's on my 3/4 ton I had to mark the treads with calk and check wear patterns after a short drive (couple hundred yards) to find the best pressure.


Current truck was spec'd for 38lbs with 235/75r17 and is wearing evenly with 38lbs and 265/70r17 tires. Same/similar load ranges, though.

42 to 44 psi (cold) is usually a good place to start on a 10 ply used on a F-150. This would be for daily driving. Carrying a heavy load or towing you always want to add some air...this is depending on the weight you're hauling or towing. Truck look's great...look's like it's leveled in the front!

Thanks, it does look slightly leveled at some angles, but it's stock. Discount tire set them at about 38, and I was concerned it was a little too low for a 10 ply. Drives fine, but I think I'll bump em up to 42 since I never tow and see how they wear before the first rotation.

That tire is probably rated 65 or 80 psi max on the sidewall but you only want to go this high is when loaded to the max or towing heavy like I said. When you check the air pressure always do it cold meaning the tire hasn't been rolling in awhile. When rolling on hot highways it's normal for air pressure to go up about 2 to 3 psi easily. I've had many 10 ply tires and have always found 42 to 44 psi gives the best ride..and tire mileage. Good idea to check alignment if you haven't already.

I have 295x75R18 terra grapplers and after the chalk method I run 44/40 in them. Ride great both on and off-road.

I'll have to be on the lookout for your truck since I am in the Woodstock area every now and then.


I am running 10ply with 40psi getting even wear and great ride.

Sounds good! I just bumped them up to 42 all around. Fronts were at 38 and rears were 36/37 before. It seems to ride a little better at 42...
