D, E or F Load for a 35x1250r18?

I have 2020 SR5 I’m looking to get new shoes for and I’m a little confused about the load rating. I understand that an F load is better if your towing stuff. I’m not, but I have added a a lot of weight with upgrades to my truck (front and back bumpers, two roof racks, camper shell and bedliner). I see a D option for the tires I am looking at, but wondering if the extra weight will make them not right for my set up. I’m guessing E Load would be safer but with tires in short supply I don't have that many options to choose from. For the record I’m looking at Toyo Open County AT3, Mickey Thompson Baja Boss AT and Cooper Discoverer AT3 XLT.

 

Load your truck up, go get it weighed at a scale, divide that weight by 4, and your tire rating should be well over that number.

 

E load is the max I would put on a half ton truck. I am currently running E load, only because that is the only choice available in the size tire I run.

D load would be better, C load would be ideal, but few tires that fit our trucks are available in that load rating. Generally tires for our trucks are SL (standard load) or E. I cant imagine running F load tires on a Tundra. They would probably feel like wooden wheels on the truck.

 

You’re better off getting a tread pattern you don’t want than buying F rated tires
