.....When I buy tires, they will for sure be E rated to help with towing as well as better side puncture resistance as the BFG has a 3 ply side wall.
That's a great looking new Tundra.
I agree about the beefier tires. Sometimes with heavy loads my stock P series Bridgestones were tossing chunks of rubber! I got a separate set of LT rated Goodyear Duratracs in the stock size, and no problems whatsoever since. You'll take a handing/braking/mileage/ride hit, but if you need the capacity it's worth the cost. I mount up P series rubber for the summer for road trips and light towing.
My Tundra is just turning 10 years old, and going strong.
Good luck!
