I sold my 5th wheel trailer but am keeping my 99 F350 CC, 2WD. So I won't be loading the tires like I did before.
The Firestones are shot: still has tread but sidewalls cracking badly (at 50,000 miles).
Should I stay with the E load range or is D load range OK? Ds are a little cheaper, and may ride a little softer. I plan to stay with the 265-75-16 unless there is a good reason to go wider. Planning to go with Bridgestone Revos but will consider others if I cn find a lot cheaper. E load range is $162 at Costco (includes lifetime rotation/balance, flat repair, road hazard).
The Revo is an outstanding tire. I would have put a set on this truck but they dont offer it with the proper load rating for the 17" wheel. D rating should be OK without the 5er. I put 285/70/17 Toyo ATs load range D on my F250. Rides much better than before.
I have 265/75/16 Revos on my Ex and I love them. They are "E" load range though. If you don't need the higher load limit, the Revo's come in a 285/75/16 "D" load. They will look alot better under your SD!!
TireRack.com has all the load limits for tires. Figure what you need and then see what the tires you are considering have. I have upsized so much in the past that I sometimes replace E's with D's that have comparable weight limits. Example: On my 15 passenger Ford vans, I remove the 245/75 x 16 E rateds and put 265's in front and 285's in back (all D rated). Part of the weight limit comes from the construction of the tires and some comes from the size of the tire. The more volume inside a tire, the higher the limit.
I replaced the Firestones on my truck with B F Goodrich ATs although the bfgs are D not E the load is not a lot lower. The side wall on the BFGs are 3 ply in stead of 2. The ATs ride better than the old Firestones.
D vs E load range... Go with E when running 265/75/16, the Revo in this size should ride quite well. The heavier weight rating in the 265 size could be a critical factor someday on the road far, far away from home. The issue with 285's (D rated) is possible complications from mounting on a stock 7 inch rim which is narrower than typically spec'ed for a 285- While I do run 285's studded snow tires in the winter on my PSD, I don't do any heavy pulling during those months.
I'm considering getting some new "summer" tires which I will use for heavy towing using stock 7 inch rims. The 265 E have similar weight ratings to a 285 D but just as rlh68050 stated earlier, the 285's sure look better on a SD. With that said, what are the opinions on running 285/75/16 on stock 7 inch rims while pulling heavier loads?
