I am looking at putting new 285/70/17 Firestone Destination A/Ts on my 17" off-road rims for my 2WD 1500. My truck is driven 100% on road with a load of gravel/wood etc.. about once every month.

Here is my question, "Would the P285s (load rating of 2,833 lbs) be OKAY for my type of driving or should I opt for the LT285s (load rating of 3,195 lbs)"

I understand the "P" tires would provide better ride and quiter noise, but I'm concerned about lateral sway (sidewall movement) and load capability.

Thoughts?

 

I'd stick with the LT's, i would rather have the better more durable tire than the difference in noise lol just turn up the radio.

 

I would get the LT's then you dont have to worry

 

LT's. they'll be load range D or E so you can haul stuff. also much stiffer sidewalls.

 

Do the stiffer sidewalls help limit side-to-side sway?

 

Of course.

 

The P rating will last longer. For the amount of towing you do and no offroad driving I wouldn't spend extra money on LT's. I've got P rating on my truck and they're just fine.

 

why do you want to run a 33" tire on a 2wd truck? did you regear the rear? i'd just assume it would make the truck a little more sluggish..... my 285x75r16s kind of do.......

 

The difference is how many plies are in the tire thus giving it a sturdier tire to carry large loads. Here is a thing about P and LT, and since I just left Discount Tire (worked there since 2005 while going to college) it's still a little fresh in my head.

LT (Light Truck) Metric tires have higher maximum inflation pressures and higher load carrying capacities at higher inflation pressures than P-Metric (Passenger Metric) tires. Conversely, below 35 psi Passenger Metric tires carry higher loads than LT Metric tires of the same size.

For example: A Passenger Metric tire sized P245/75R16 109S carries its maximum load at 35 psi which is 2,271 pounds.

A Light Truck Metric tire sized LT245/75R16 at 35 psi carries a load of only 1,700 pounds. At 50 psi though the load increases to 2,205 pounds. At 65 psi it is 2,623 pounds and at 80 psi it is 3,042 pounds. 50, 65 and 80 psi are the maximum loads for C, D and E load range tires respectively.

If you have a truck that specifies LT Metric tires under no circumstances should you install P-Metric ones as replacements. P-Metric tires will not have sufficient load or inflation capability for your truck.

 

also, i started to really hate working there, but why not buy at discount tire? they do have better deals than ANY tire store plus the managers got a lot of brown sh*t on their noses from helping the customers. hell once i leave GA, i'll shop at discount in the future.
