What Size Were Stock 95 Yukon Tires?

What size were the stock 95 Yukon 4wd tires?  My Yukon had a body lift installed by the previous owner with 33" tires.  

 

Going down the highway at 70-75 mph, it has trouble pulling up grades without downshifting to maintain speed.  Do stock 95 Yukons have this problem, or is it caused by the taller tires?  It has 3.73 gears, by the way.

Stock tires would have been 245/75/16's.  The 3.73's are likely the problem.  You'd be better off with 4.10's, but the problem could be any number of things.  The 350 under the hood is pre-Vortec, which was rated at 225HP compared to '96 and up 350 Vortec which is rated at 245HP.  Again, things like the miles, air intake, exhaust, weak plug wires and on and on could be also contributing to the problem -

 

PS - The 33's are equal to a 285 or 295/75/16

Mr. Dave:

 

"Height Kills Ratio"

 

That's just one of those axioms, like "lefty-loosy righty-tighty" ya know.

 

I had the same setup ....3.73 gears and a 1995 350 in a 4wd. My truck's performance was super....until I stuck on a set of 33"s....  Sure the 33's were great in the sand and mud.... But I could do much of the same with the stock tires!

 

Good luck.  PS  I wouldn't change my rear end ratio unless I had a pocket full of cash....you'll have to do the front too ya know!

Thanks for the replies.  I bought it with the 33's on it and really don't want to go to 4.10's.  The truck is in great shape mechanically and the engine feels as strong as its going to in a vehicle this heavy.  So it looks like my only reasonable option is going back to a shorter tire.  Hopefully that will help with mileage too. :(

You could go back to a 265/75/16 and that will certainly help.  You could also try a tall and narrow tire for less rolling resistance, but it will still probably affect the drivabillity some.

Yeah, I've been thinking of going to the 265/75R16's.  It looks like I could go to that size and take the body lift off.  It looks like the only place I would have interference now without the body lift is more because of the width of the tires and not the height.  

 

Anyone know what a stock aluminum wheel and 265/75R16 weighs?

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      4 low is really nice on steep boat ramps.

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
