Default Cooper Discoverer S/T 265/75/16

I have a stock 2006 dakota, just replaced my sway bar links and front tie rods and since those were bad i need new tires also. I am wondering if people think these will fit on my truck.

Cooper Discoverer S/T 265/75/16

Also on a side not my shocks are really bad but i just dont have the money to get them yet. In the process of a move and these tires are all i can afford. Although as soon as possible i plan on getting the monroe shocks x4 and a front leveling kit 2" with 1" back blocks, which will help with clearance, im hoping this happens within 2 weeks. Will that change any minds of people who say NO to these tires on stock?

Also have to get these tomorrow so any responses are welcome.

I know people have run 265 70 16 stock, but the 75% on the sidewall adds an inch to the diameter. I think that would b like a 32in tire under a stock dak. I think u will have some rub depending on tread pattern. With the life...you will have no problem.

I ran 265/75 R16 with no rub, on a stock 06 dakota. They didn't rub. The only reason they did not rub is because I am running the 16x7 steel factory wheels. The 16x8 aluminums will cause the tire to rub.

My sig picture below has the 265/75 r16 tires on them.

Since then I have gone back to factory 245/70r16 for a number of reliability issues that I had. To sum it up, your rolling the dice throwing those larger tires on your truck, the front end rack and pinion system is rather weak, and the additional pull and unsprung weight of the larger tires could cost you some cash in the long run. I can't imagine anyone would recommend it on a daily worker/driver. A toy however, why not.

265/75/16 may fit, some guys can fit that size on their stock trucks, and some have rubbing issues on the fronts. Even with a leveling kit, sometimes there still needs to be trimming. Rears do not matter, they would fit stock. You'll be taking a gamble with a stock truck.

I currently have 265/65-17 (stock). I just put a 2" leveling kit on and am going to 265/70.... I'm not sure a 265/75 would fit without rub even with the leveling kit.

Keaton...remember you have a 1in head start bc of your rim size. So a 265/70/16 is 1in smaller than a 265/70/17. The rest of the numbers are as follows:

265=the width of the tire in mm
70=sidewall height (the percentage of the width)
16=rim diameter

To calculate the height of a tire...

265(width)*70(sidewall height)*2(need to calculate two sidewalls as there is one on each 'end' of the rim) + 16 (rim size)

U need to convert your rim size to mm or your other calc to inch before you add them.

265/75-17 would be a 32.64" diameter tire....the 265/65-17 is roughly 30.5". dont know if I have enough room to add 2" in tire diameter.....going 265/70-17 is right in the middle at 31.6" diameter. I'd love to do with the 75 sidewall....but with only a 2" leveling kit, I can see it rubbing somewhere.

Keaton...I don't think I've ever seen a 265/75/17 tire. Its either 265/70/17 or 275/70/17 or 285/70/17 if u wanna go larger.
