If I run 45-50 psi on LT "E" tires will they still be alot rougher riding than P rated stock tires? I had LT "E" terra grapplers on my old truck and they beat me to death. I think I was running higher psi but I am not sure to be honest. I am so confused if I want to to go with Cooper AT3 P265/70/18(32.6") @ 43lbs each or LT275/70/18(33.10") # 56lbs each with my 2" leveling kit..

I recommend a lighter LT tire, like the Firestone Destination AT or Bridgestone Dueler AT Revo 2. Tire weight sucks performance.

 

Yes, they will run rougher no matter what you do, within reason. P rated tires are basicly car tires. E rated tires are heavy duty truck tires. Reinforced sidewall, most run to 80 psi.

 

If you are going to change tire size, you should seriously consider a tuner to be able to correct for the tire size difference. Shift points change, and you will miss the power loss.

Rinkey-dinkey tires on a leveled truck look retarded.

285/70/17 (overall stock height equivalent on bridgestone blizzak winter rubber)




295/70/18 Trail Grapplers

 

So the first picture is with a 32.7" tire?

I think it looks fine that way!!!

 

Unless you load your truck down a lot or pull a lot, E-range tires are a hard ride. I put E-range tires on my 04 F-150 and it might as well just been hard rubber casters instead of pneumatic tires I was running those @ 47psi.

Under a load they weren't bad, but unloaded, which is the majority of my miles, it was fairly rough.

 

I just put 275/70r18 BFG E rated tires on my 2" leveled F150. running 45 lbs air. The wheel I got is particularly light. The weight is about 4lbs heavier then the stock wheel/tire setup.

 

What was your wheel weight?

What does the stock wheel and tire weigh?

I ordered the same size tires as you and some rims and I'm interested to see the weight comparo.

I think the BFGs weigh 57 lbs? Stock SR-A Goodyears weigh 39 lbs?

I just can't deal with a highway tire.

Also, I just sold my 03 Cummins and only ran 48-50 lbs in the front and 42 lbs in the rear with E rated 35s.

I was thinking like 35 psi in the BFGs on my new FX4 F150.

 

Well I am going to stay with the 32.6" tire. Even though I really like the 275/70/18 look I am hoping the 1/2" difference will not make a big difference. The tire is rated for 2,750lbs so it will be more than enough for what I tow and I want to keep a good ride but have a better A/T tire. It is getting done on Friday so I will try and post pics that afternoon but LSU/Bama play saturday so not sure if I will get around to until next week.

Geaux Tigers!!!

 

I put Michelin LTX MS tires on my 03 5.4 screw. They are LT tires and ride just like the passenger tires that came on the truck.

 

What load range are they?

 

I know the Michelin are great tires but I need something more aggressive for hunting.

 

While I haven't run any yet, I would look into the Firestone Destination AT as someone mentioned above. I researched a lot of tires and these look like a very good tire with great survey ratings.

 

I have a friend who has the Destination AT and likes them but I am going with the Cooper AT3..

 

Sorry, I just realized you weren't asking for suggestions on other brands, and you already decided on the Cooper AT3. That's a great tire too.
