Home Forums Gear Hunting Trucks and Four-Wheel Drives Question about tires on a 2002 Dodge Dakota Quad Cab 4X4

I have a 2002 Dodge Dakota Quad Cab 4X4. It came with 265/70R16 Goodyear Wrangler RT/S tires. I want to put 265/75R16 Dunlop Radial Rover RT tires on it. There about "one inch" taller. Have any of you even put this size tire on a Dakota like this? If so did you have any tire rub or any other problems with them? Dunlop doesn't make the Rover RT in 265/70R16 so I have to go with the 26575R16. I don't think "one inch" is gonna make that much of a difference. Thank's. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />

Most likely there won't be a problem, but you may have to recalibrate your speedometer for that extra inch. As Dodge usually has miles of room under the wheel wells the extra rubber shouldn't rub, but the tire pros at the shop(unless youare a DIYer) will let you know right away if it will work or not. Are you doing this for a little extra clearence underneith?

No,the only reason I'm going to this size tire is that Dunlop doesn't make the "Radial Rover RT" tire in 265/70R16. I can't find a tire that I like in 265/70R16. Like I said the truck came with Goodyear Wrangler RT/S tires, there "all right" in the snow if you don't get to much. I live in Central New York, we measure snow by the foot not the inch especialy up on the "Tug Hill" so I need a "really good" snow/mud tire. I looked at the BFGoodrich T/A KO's, they make them in the 265/70R16 that came on the truck but I've been told they don't "clean out" in mud that good, and there $30 to $40 more per tire. From everything I've read and everyone I've talked to say the Dunlop Radial Rover RT is just as good in the "snow" and a lot better in the "mud" then the BFGoodrich T/A KO. Plus they said the Rover RT will last longer, isn't any louder and handles as good as the BFG's.
By going "one inch" taller that's really only gonna be a "half inch" bigger on each side so thats not much at all, I don't think so anyway. Thanks for the info. If you or anyone else has anymore please let me know <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

I have the same truck & with chains I would never get away with the extra 1". That being said I have never had to chain up, yet <img src="/ubbthreads/images/graemlins/grin.gif" alt="" /> The Wranglers have performed flawlessly for me here in CO. Novemebr hunting in 4"-18" of snow with ice under it. If you never chain up I say go for it!

In case you need to figure out the dimensions of a metric tire:

Take the 265/70R16.

265 is the width in mm. Divide that by 25.4 and you get a nominal tire width of 10.43"

70 is the percent height ratio each sidewall is of the width. 265 x .7 = 185.5, which is the height from the rim to the top of the tread. Since the tire is round, we must multipy 185.5 x2, which = 371.

Divide 371mm by 25.4 and you get 14.6".

Add 14.6" of tire height to the 16" wheel, and you get a nominal tire diameter of 30.6".

So, the formula is:

1. Width in mm/25.4 + width in inches

2. Width x height percentage x 2 / 25.4 + wheel diameter = total diameter in inches

I find this a very useful formula..................

I have an '01 extended cab with the 4.7, automatic and 355 axle.
I put 265/75-16 8 ply tires on it. They were allegedly 1/2" taller. I get some tire rub when turning and the truck is tilting/twisting, though not very bad. The main thing I noticed was that when I tow my camp trailer (23'), the transmission shifts back and forth quite a bit at around 35-45 MPH when pulling a slight to moderate grade. This is a result of the dual range 2nd gear in the truck. It tends to "float" back and forth a lot within the dual range. I also notice a slight difference when pulling hills as a result of the change in effective gear ratio. The speedometer reads about 3% slow. In normal freeway driving I notice that the transmission wanders between 3rd and overdrive, also as a result of the change in gear ratio. The tires that came on the truck were the perfect match for the power and ratio I have. If your truck has the 392 axle, your results may vary from mine.

Do you think the rubbing is bad enough to cause any damage?


So if I'm going 65 MPH the speedometer should read about 63 MPH?


My truck has the same drivetrain as your truck.
