Here's the situation: I have a 2007 Toyota Tundra Crewmax Limited 4x4 with the 5.7L engine, and heavy towing package. The Max gross vehicle weight is listed at 7,020lbs, and the max towing weight is listed at 10,100lbs. I've only towed a max of maybe 6,000lbs before, so it the tires really never made any difference. Now, with a much bigger, heavier tractor, and some implements, I'm looking to add a 10-12K max gross weight trailer (12K only for some extra safety factor, and in case I get a truck with a higher max towing weight). I don't plan many trips, or any long trips, but I want to be able to haul my tractor and implements myself without worrying.
The truck came with P275/65/18 tires, with a load rating around 2300lbs at full inflation (44psi). I've hated the tires since day one (really bad in the rain), and they're just getting to 50K, and while they have some tread left, it's time for them to go. The tires I'm looking at replacing them with come in both P and E ratings, so roughly 2,300lbs and 3,400lbs respectively.
I keep doing the math, and if I assume I'm only loading the trailer, and it's right around 10K, I don't see how I'd go over the limits for the P rated tires. The truck empty is ballpark 5,500lbs, and the tongue weight shouldn't be over 1000lbs, so I'd only be adding 500lbs to each rear tire. They should be able to handle that pretty readily, it would seem
Am I missing something? Oh, BTW, the trailers I'm looking at all have brakes on both axles, and I've got a lot experience pulling heavy loads (drove big rigs, tandem dumps with tag-alongs, cement mixers, etc as a kid).
The E rated tires are actually $8 cheaper per tire, so it's not a cost thing, I'm just wondering how much harsher the ride will be going with the E tire, and there's no way to guess at that. Thoughts?
