1999 Ram 3500 Diesel 4X4

So after much reading, eyeballs cramping up, the budget swelling to $5-7000 for some stuff I was looking at :shock: I decided my biggest bang for the buck setup for bigger tires is as follows.

315/75/16 Goodyear Wrangler Duratrac Load Range E (3860 lbs) 64 PSI max
(basically a 35X12.50)

Stuffed on the stock wheels. I was a lil iffy about this but seems tons of people are running em on stock 6" wheels with no reported problems besides maybe being a lil rounded on the tread on some tires.

2" spacers for between the rear duals. Suggestions on brands?

2.5" Top Gun Customz leveling spacer.

OPTIONAL: Either a 1" taller (2" total) block for the rear or some add a leafs to lift it another inch or two.

Seems I won't need longer brake lines or anything else, or am I missing something??? Anyone have any input, good idea, bad idea, you just saw your neighbor chasing a sheep with his pants down and you feel like sharing etc?

Sounds like your list has got it all you may consider a wider spacer though I uses a 2" with my 285's and it does not look like I could squeeze 315's on and still tow a heavy load. Also you stated the tires are load range E but max pressure is 64 psi? They should be 80 psi

Yeah I thought it was a low PSI as well. Specs show an E rating and 64psi max though? Found those specs a few places for this tire. Heaviest I'd normally tow is a 3000lb race car on an open trailer. Maybe an enclosed if I need to tow a buddies trailer with a similar weight race car or something similar but unlikely.

65 psi is what a "C" or "D" has for max psi. That is really weird an "E" has that low of pressure. But I have heard and seen stranger.LOL

Yea 65 is usually a D rated tire. However, big tires a lot of time have a lower pressure rating, it is still a 10 ply tire and can hold more weight than a stock size tire because of the increased surface area.
