Hi, new member here with my first post. I am researching the GX 550 and ran across this thread…. A Load E tire is way too stiff and HEAVY for this truck!!! If you zoom way in on the first pic, you will see that it is Load D (8 ply), max load 2750 pounds, max air pressure 51 psi. IMHO this is a perfect choice, but I can’t find it in the Toyo website. It may be a “dealer only” item, which is not great. There not that many choices for a Load D AT tire in this size. This tire probably weighs around 42 to 45 pounds.
I am running Load E Cooper Discoverer AT3 All Terrains in this same size on my 2013 Land Cruiser 200 (and also ran similar ones on a 1996 LX450). I installed them on the 200 only because I was towing a 6000 pound trailer. They greatly stabilize the ride when towing and run cooler, but the 10 ply sidewalls destroy the ride comfort at all other times, even when running the normal 42 psi. They also destroy the fuel economy…
This Toyo tire is rated 5 stars for winter traction, that is laughable. There are hardly any sipes and the tread compound of a 50,000 mile tire is way too hard for cold temperatures. It does look great and should be a good three season tire, unless you live in the South.
