So, it appears I'm going to be replacing my stock tires on the F150 a little sooner than anticipated as I noticed some unusual sidewall deformations the other day while detailing. Anyways, truck came with LT235/75/r17 Load E tires and the 7200# suspension. I'm considering switching to a 265/70r17 tire and notice a huge price difference between the P-metric tires and the LT tires. Doubt this truck will see much towing, though the occasional firewood and boat launch trip is likely but its mostly a highway commuter with occasion two track use.

Seems like both the D and E range LT tires sport an additional body ply compared to the P-metric tires as well as roughly 1000lbs high weight rating (so about 2000lbs per axle I guess). While I'm sure it would be safe enough to run the p-metrics would I be sacrificing anything in handling or durability? The last thing I want is to pick up a flat on a fire trail because I saved $300 on p-metric tires...

 

IMO stick with LT tires.

 

Kinda shocked Derrick from The Tire Rack hasn't yet chimed in here.........

Cheaper ain't better especially when you're talking about tires! The LT's were factory-installed for good reason. The few hundred dollars you might save one time could be wiped out immediately with a failed tire that causes an accident.

Despite your anticipation of limited or no real loading conditions its probably the occasional use with P-rated tires that would be the real problem.

FWIW I'm running a set of Michelin LTX's on my E250 since '08, 62K miles with no less than 40% of original tread left. Paid about $800 for the set, trouble free since then so not a bad investment IMHO.

Stay safe---it ain't worth it to do otherwise!

 

LT stands for light tuck, the F-150 qualifies.
Cheap 'LT' tires would be better than expensive 'P' tires for a pickup, especially if you're carrying wood etc.
