I know what the OD's are of each size. I just picked an arbitrary number to use. The 265/75-16 is the EXACT same OD as a 235/85-16. I do trust you that the 1" taller tire (1/2" taller truck height) "looks like more", but trust me when I say, they look ridiculously narrow. It's your truck, you can do what you want. But why not get the exact same OD, practically to the tenth of an inch, and have a tire with a decent tread width.

edited - Of course, you have a different width wheel than I do. I have a narrow 6.5" wide wheel. Perhaps with your wheels, the 235's will miraculously appear like 285's!

 

I'm not really wanting a taller looking truck right now (well, I'd love to have that, but I'm not excited about the 0.5" of increased truck height that I'll get with these tires), but rather, I'm excited about how these tires will fill the wheel wells up more (again, just 1", but it looks like more). See how tiny these tires that I've been running on my truck look?





Because these tires that I'm going to were free (my step-dad already had them sitting out in the garage) and I've spent enough money already to pay for the various post-wreck repairs and court fees. If I'd had the $800 in the first place, I would have already been running 315s when I had the wreck.

 

Guys, keep in mind that not all stock wheels are the same size!!!!

Some trucks came only with 16x6.5 tires. If you have 245 tires as the OEM size, DOUBLE CHECK WHEEL SIZE.

If your wheels are only 6.5 wide, then 285 is the largest width to run, and the 235/85 will fit perfectly.

Conversely, if you have the 16x8s, you CANNOT run a 235/85 tire on that rim-- the rim is too wide. If you have the 16x8s, then the 315s are the biggest you should run.

A good rule of thumb is that if your OEM tires are 245, then you have the skinny 6.5W wheels. If your OEM tires are 265, then you have the 16x8 wheels.

YMMV

HOHN,

Can you help me figure out what size my wheels are?

I measured the size of the replacement wheel I bought (which is a factory wheel) because it looks to be the same "thickness" as the dented wheel I have (sat them next to each other--although the dented wheel still has a tire on it). Anyway, the new wheel seemed to be about 9" thick overall. Not sure where the number is supposed to be measured. Thanks.

 

The wheels should be measured from bead too bead. As for which ones you have, check the sticker on your door. It will tells you what size tires and inflations for them. If they say too run the 245 series, then you have the 6.5" wheels, and can safely run 235's. However, if your sticker says your truck has 265's, then unfortuanltey you will run into problems with the 235 series tires.


This is incorrect HOHN....you can put a 235 on this rim and drive away happily. But the second you rub a curb, the bead will likely pop leaving a flat. As well as, the obvious problems with tire wear.

 

You need to cut two length of wood to be exactly 16" (wheel diameter) long.

Put one on each side of the wheel in question and you should be able to measure the wheel width through the hub. It will be either 16x8 or 16x6.5.

Judging by the pic you posted, it looks like 16x8, as I think the 16x6.5s were a different style. Measure to be sure.

If you have the 16x8s, the "perfect" size in terms of fitment is a 285/75. If you want something skinnier, try 255/85.

Look at the tire manufacturer's specs for wheel width and you'll see that they spec an "acceptable range" and "ideal", which is usually in the middle of the "acceptable". For 285s, 8" wide wheel is "ideal" so you can expect best results in terms of treadwear.

Actually guys, the wheels seem to be 16x7.5s. Is that right? Not 6.5, not 8, but 7.5. Here's the door sticker (not the window sticker):



Anyway, bottom line, will my "new" 235/85 R16 tires fit on these wheels?

 

My door sticker says the exact same thing.

But, my truck came from the facory with 265X75R16 tires on 16x8 forged aluminum wheels.

The bigger tire and upgraded rim were noted on the window sticker, no mention on the door sticker.

Measure the rims to be sure.
When I measured my stock wheels, I came up with 16X9 though?
It's hard to measure from inside the bead to inside the bead.

Well SOB. It looks like the wheels I have are in fact considered to be 8 in wheels. And I guess that means that the "new" BFG Wrangler LT235/85 R16 tires will be too narrow. The tire spec page on Goodyear's site says it needs a 6"-7" rim width. So I guess my 8" width is out of the question.

 

OK, so if I want to put 315s on these 8" wheels, what are some good recommendations? I've been giving the Discount Tire website (www.discounttire.com) some good looking...

 

Here's the tire I'm considering going to. It's a BFG All-Terrain T/A KO 315/75 R16.



I think it looks pretty sweet, would fit great on my 8" wheels, and would fill up the wheel wells REAL nice like. Thoughts?

I also like these though. It's a Nitto Terra Grappler AT 315/75 R16.



They're $162 each, compared to $202 each for the BFGs.

 

I am running the bfg at's.They are great tires,but I wish they were e-rated.I think the terra grapplers are.I think next i'm goin eith the goodyear mtr's.We have them on our ranch jeep and they are pretty sweet.But you will love the bfg at's.

 

First off - http://www.4lo.com/ and check out their metric tire conversion calculator... super handy


Secondly, I recently bought a set of 285/75 16 Nitto Grapplers for my Dodge and am pretty happy with them. They fit stock - rims and suspension - and look great. A little loud for an A/T, but who cares

If you are considering ordering tires online, I ordered from www.tires.com and at the time (just befoer Christmas) were offering FREE SHIPPING. At their prices, and with free shipping - it was impossible to pass up the deal. Looks like now they are charging for shipping, but they may offer the deal again soon

 

I'm kind of wanting these Pro Comp All Terrains now...

 

What about these?


The 315's aren't load range E. But I don't load my truck that heavy anyway.
