anybody run this size tire 33x10.5 15

alexfiggy · 01-12-2009, 09:58 PM

i just found some why 10.5 ? does this eliminate the need for spacers on a rim?

I plan to, and yes on stock rims there should be minimal rubbing at full lock. Now whether or not you're going to be jamming them into the fender is another story. They're also better than 12.5 in the snow/rain - less coverage.

i also plan to run this size for the next stage of my build. better mileage, better in the snow & ice and doesn't look stupid wide like 12.5 on 15x10" wheels.

12.5" wide tire sticks out 1" further on each side of the wheel...

I used to run 33x10.50 BFG ATs and I liked them.

Ill be running them when I get my rear axle in, already bought them in fact, I went with them because of the snow/rain superiority as compared to 12.5 and I actually like the tall skinny look.

im trying to figure out what my next tire is going to be i have 31 pro-comp m/t right now?i ordered the 1.25 body lift with 1 inch motor lift i allso have 2 inch spacer lift.i want to get the ome 2.5 lj lift as well.what size tire would you recomend?

I ran 33x10.5 BFG MTs for 15,000 miles. Awesome tire!

with the 42RLE you want 4.88s for 33s.

Just got 2 33x10.5 KM2's. Waiting on the other 2. Gonna put on the stockers without spacers.

I have pretty much everything you have, 3.73s, 42RLE and 33x10.50s. Drive it everyday.

33x10.50's on stock rims will rub on the control arms when turning sharply.

Personally, (having run them in the past) I much prefer the 12.50's.
On a jeep, I don't buy the mileage and traction advantage story.
In some terrain the 10.50's will actually offer less traction.
(I won't explain my experiences here, as it's late...)

Another problem with running 33's on a lifted jeep with stock rims is that you haven't increased the overall track width in conjunction with the increased center of gravity. You're taller, but not wider, so you've created a jeep that is MUCH easier to tip over in off-camber situations or high speed street maneuvers.

Also, when you see a jeep that turns your head because it looks tough, it's because that jeep is running wheels with a different backspacing (or spacers) to get that wider stance that is classic jeep.
Give me some 12.50's on a 15x8 rim with 3.25" to 3.75" BS any day!

Bottom line, get wider!
More stability, no rubbing from turning and that classic tough jeep look.

10.50's on stock rims just look wimpy to me in comparison...

33 x 10.5 on stock 7" wide steel wheels with 5" backspacing. 42RLE and 3.73 gears.
Clearance between the tires and the upper rear spring perchs is your main concern. Most stock wheels have a 5.5" backspacing which makes it really tight.

Another positive point to 33x10.5 vs 33x12.5 is the lower weight and rolling resistance of the smaller (width) tire. It will be easier on the brakes and on acceleration. The BFG KM2 33x10.5x15 is 49-lbs. The BFG KM2 33x12.5x15 is 61-lbs. Unsprung weight makes a difference.

I run 33X10.5 all summer and have 33X9.5 studded and siped for the winter.

You will rub turning without proper backspacing, my 10.5's are on proper backspacing and I love them, my 9.5's on stock and I had to add enough washers that by next winter I will put them on aftermarket wheels with proper backspacing as I do not like the increased turning radius.

12.5's will not prevent you from rolling over, proper backspacing puts your tire center in the same place.

Heavier/wider tires will perform worse on a daily driver - on a 2.5l you will actually notice degraded performance in acceleration when going between two identical Jeeps save tire size. Braking and steering is worse equally on the 2.5 or 4.0 with heavier wider tires.

I will take performance over looks any day and for my Jeeps usage and local terraing the 10.5 was a very clear choice over the 12.5.
