Another tire load question

[ryanm33]

I know there are hundreds of questions on forums( I have read dozens of them) about LT vs P Metric tires, but i can't find the answer to my specific question. I have an 06 Sierra 1500 that needs new tires (265/70/17). I am looking at the duratracs because they are on sale at the moment. I can get P Metric ($182.00), C ($230.00), or E ($225.99). i understand that E are 10 ply, heavier tire, and more load. A P metric is a passenger tire. My question is... According to goodyear's site the load for the P metric with a load index of 115 is 2679 lbs. The C rated tire is 2469 lbs, and the E rated is 3197 lbs. The truck will be empty 90% of the time. It only hauls a 16' aluminum boat, or a 6x12' tandem trailer I use for home renovations.Will the P metric tire be good enough for me? It has a higher load rating than the C rated tire, but it is $50/tire cheaper. Why is this? Should I spend the extra money on the LT tires? If so, why? The P metric seems more than sufficient to me. I should mention this is a second vehicle and doesn't see many miles and I am not concerned with ride quality

If what you're hauling is within the limits of the pickup, the P metrics will be ok.

 

But my #1 concern is durability, and if that's what you want the E tires are the way to go.

When towing with p rated tires you need to derate the tire capacity by 9%. Though you probably will still be within the tires specs after the derating.

 

As mentioned, a LT tire will be more durable, but it all depends on where you drive. Never off road, probably be fine with the P's. Off road all the time, go with the C or E rated tired for the sidewall protection.

 

Not sure where your at, but I had great luck with the Cooper A/T3's as an alternative suggestion. May be a little cheaper.
