Whats the largest i can go on a 16x7? i was looking at 315/75/16s, but i was told they are too big.

Im looking for a mud tire, like the firestone destination MTs. but as large as i can possibly go on the rim. i can take care of the body. and of course, load range E.

So if you have recommendations, i would appreciate that. Thanks in advance

Sorry for the delay,

Is your truck lifted? 16x7" wheels are going to limit how large of a tire you can run. You'll be able to get away with a bigger tire with some 16x8's.

I think your rim width should be about 75-80% of the tire width. I would say closer to 80 just because you dont want to put that much stress on the sidewalls especially if your hauling anything.

Each manufactures has recommended tire widths for each tire size they sell. You want to stick within these recommended ranges so that you maintain your tires manufacturer's warranties and you stay safe. These recommendations can be found on most tire manufacturer's web sites under the sizes and specs for each tire model.

Tire manufacturers will tell you that a 285/75R16 is pushing it - most tech/size data for that tire size will list a minimum rim width of 7.5.

However - many owners with stock 16x7 rims are running LT305/70R16 or even LT315/75R16 with no problems and work the trucks daily. I myself have run 3 sets of LT305/70R16E (2- sets Nitto Terra Grapplers & 1- set Kumho KL71) - work the truck with frequent heavy hauling and towing and have had no adverse problems.

That said - you have to be aware that the tire will balloon more then designed - you have to work the air pressure to get a flat footprint more so then with the "correct" tire manufacturer recommended rim size. There is a risk and no tire manufacturer will warrant any "damage" due to tire failure due to you mounting an oversized tire on too narrow of a rim. Its a choice you make.

But other then that - you can physically fit 285 - 315 on a stock 16x7 rim. But if you have the extra cash - upgrade rims to 16x8 or 16x9.

Thanks, thet helps a lot. i dont really tow anything, so i think if i get the 315/75/16s, ill be able to air down to like 55 and have a flatter footprint
