I'm looking for tires but tirerack.com list my stock tires has either the 235/75R15"s or the 31x10.5 15"s. The problem I'm having is the tires I have now are 265/70R15's my local tire dealers are telling me that most Durangos cam with that size tire. I just want the best size tire for gas mileage and looks but mostly gas mileage. I drive a 2000 Durango sport with the 4.7L engine
 
skinny is best in mpg savings... but you can also look like a big body on skinny legs.. but if you dont care then go as small as you can while maintaining the proper load range for your vehicle/capabilities.
 
265/70-15 sounds like a weird size...these trucks often came with 265/70-16 which is an inch taller. I've seen 265/75-15 before...

Either way, 31x10.5-15 would be a direct swap tire but as mentioned, the 235/75-15's will net better mileage by being lighter, narrower and a tick smaller.

ya I thought it was weird that my local tire dealer said that the 265/70 was a stock size. I looked at my spare today and its a 235/75 so I don't know I'll have to see I got some life on my tires now so I'll see what prices I can get
 
How big can I go stock?

My 02 QC 4X4 has a hodge-podge of 235/75-16's to 265/70-16's on all stock rims. It looks like I can easily go up a size to 275/70-16. They need replacing soon, what is the largest I can go, unlifted? I will occasionally be hauling and towing.
 
You've got mismatched tire sizes on a 4x4 vehicle? WTF. That's just asking for trouble...if 4wd ever gets engaged and you happen to drive on a high traction surface, you'll be putting some serious strain on your driveline.

265/75-16 is a very common tire size and should clear with no issue. If anything, a teeny bit of rub on the front bumper which you can trim or slightly crank the t-bars for clearance.
 
It was an auction vehicle that I just had delivered (it doesn't even run yet) and the tires on it are what came with it. I would never drive ANY vehicle with mismatched tires AND I would never drive in 4WD on traction surfaces even WITH matching tires. I just want to know what I can replace them with.
 
Don't take any offense there, I'm just putting that info out there. I don't know what you know about vehicles...

At any rate, I answered the question. 275/70-16 would be a perfectly fine size, but it's not nearly as common so you'll likely pay more for it.

None taken sir (and I appreciate the intentions). Actually I did misspeak (technically). I do use 4LOW while pulling my boat up the ramp on dry pavement (although slowly and in a straight line). This is my fifth 4WD vehicle. Although this is my first with AWD, 4HIGH and 4LOW. It isn't 2WD, 4HIGH and 4LOW?

How large can it go on the stock 16's? 285, 295...?
 
Well, the stock 16x8 wheels will mount a 305/70-16 just fine, but that's a 33x12.5 tire and it won't come close to fitting on a stock truck.

265/75-16 is about as big as you want to go without a body lift. That would be a 32x10.5.

275/70-16 would be just a tiny bit wider (3/8" technically) than the 265/75-16 but basically the same diameter as stock (265/70-16).

My opinion, 265/75-16 is the tire to run. Very common and easy to get in a wide variety or brands and styles.
 
If diameter is the limiting parameter, then 275/70-16 (31.15) will fit easier than a 265/75-16 (31.64). Both are slightly bigger than the stock 265/70-16 (30.60). The higher aspect tire (75) will give a better ride but I want as big a footprint as possible and that is a lower aspect. Unless there is a BIG price/availability differential I lean toward the 275/70-16. I will have to see what is available at the auction, as that will probably be the determining factor. Getting a set of 4 new (for all intents and purposes) tires of any of those sizes for less than $100 is hard to beat, in which case I would probably take what I could get.
