So my neighbors (Dave and Luke) have so graciously pointed out to me that 32s are more expensive than 33s. True. However, I'd rather keep that extra little bit of pep in my poor little 3.3L..
32's VS. 33's

Looks like there is a lot of difference in price depending on where you are. Here the KM2s are a $300 per corner tire. The GYs are $225.

Really??? Where did they look? Every site I've looked at and store I've spoken to it's the opposite.

misread that initially... post deleted.
I did notice that 32s are cheaper than 33s up here though.

I just got a screaming deal on a fifth wheel to go with my four Eagle Alloys, apparently they're not making em anymore and letting em go cheap - $75. Bad news, the 295 70r17 trail grapplers are now 290 per tire. ouch.

Yep www.treadepot.com 33x10.50 are $178 and 32x11.50 are $190 honestly you are not going to notice a power difference.. I mean both sizes weigh the same.. The 33 may help actually gain a few mags back because it turns less times.. When I had stock tires at 70mph I was around 2700rpm now with 33 i am at 2500 rpm. Thats a big difference

But uses more getting up to speed unless you're a grandma with the gas pedal....more rolling resistance too...so, there's got to be a fine line between gaining efficiency due to lower RPM's and losing the efficiency from the extra weight and grip of the tires....

I think the lower RPM would be more than offset by the extra energy needed to turn a bigger circle - longer radius, bigger circumference, etc. However, once at the same speed, perhaps the balance would tip the other way. I wish I remembered how to do math...

congrats NM
My experience is gas mileage stays close to the same when you go larger tires for the same reasons as above. Loss of power is made up by taller gearing.
My Ram was 11 mpg on 29s, 12 on 33s and then 12 on 35s
Jeep was 18mpg on 30.5s 18mpg on 33x10.5s
I just found out the 33" on 17 GYs have been on backorder here for 4 months :weep:. So I have a question for you guys that is perfect for this thread. Would you rather:
a) lose 0.5" and go for 32s
b) pick something other than your favorite tire
c) put yourself on a indefinite waiting list for the ones you want
d) get an even bigger tire and take a bigger hammer to the fender wells. <glances NM's way>

LOL! First question, am I being congratulated on non-specific thinking which approximates actual math? As to your question, I'll give you the lawyer's stock answer: It depends. Can you find the ones you want elsewhere after consulting the interwebs? Is there another tire you can live with? As far as my tire being bigger than 33, it's not by much. the 295 70r17 is essentially 33.4", and promise you there isn't a whole lot more room to be made, thus my decision to add a 1" BL. (Of course, and has been discussed, my 4.5" backspace is a factor). Me, under the circumstances as you describe above, and if there was NO WAY I could get the tires I wanted timely, I would probably settle for another set. There's more than one good tire out there. I love my trail grapplers, (even though they're spensive). Next time, I'll probably go with the duratracs.

Thanks NM... congrats was for the 5th wheel find. Good tip - I will check around and see if I can find another distributor in my area.

I typically order tires online. Either tirerack.com or discounttiredirect.com. Discount tire will price match and sometime do more than that if you order 4 or 5 at at time. Have to call them to get the price adjusted. That's where I got the 32" MT/Rs I'm running now.
I will be going to 33s soon. Although I'm still undecided on brand. I definitely will never buy another set of MT/Rs for a truck that sees a lot of pavement. Which is why I'm leaning toward the Duratracs instead of the KM2s. I've never been a huge BFG fan... And I can't stand the look of the BFG AT tread pattern.
As far as the jump to 33s, it's a no brainer for me. The compromise in fuel economy is negligible and I already think 32s look too small and I'm not even running a full 3" SL yet and once I have that done I know they'll be too little looking.

Less rolling resistance with 10.5

^^that is correct.
However, there is a lot of thought going into something that will make a negligible difference in the end. I think the better choice is to go with the 33s, but that is just me, and every 1/2 inch of ground clearance makes a difference on these trucks. So, while the 33x10.5s were probably a really good option, the 32s are still an alright option. The differences between the two are so small that it likely won't make a difference in the future until its time to find a 32, then that will be a pain, because not near as many tires are available in that size.

I look at it this way.. You lift your truck for it to be taller... Why would you want a smaller tire then? Tires are the single best thing for offloading and the only true mod for ground clearance... Sure it's just a 1/2" but that can make a big difference on the trail.. Plus helps with departure and decent angles... I mean bigger tires look better, can be had easier, more size and company options, really why the debate?

Well what about them?

sure, but, I'd hazard to bet that the difference between a 32 and a 33 is less than an inch on most manufacturers tires, and so the difference in lift is less than half an inch. quality of said tire makes WAY more difference than an extra 1/2" of height.
I will say however, that most 32's I've found are either load range D or E, whereas most 33's are C or less in mud tires....the difference in my personal experience here is this...when you air down those load range C 33's to 12psi you're squatting them a bit. When I drop my load range E 32's to 8psi, they're still riding at full height until I ask them to flex by going over an obstacle.
I'll try to get measurements if I can get GoBUFFS to come over and let me cut air down on his tires for height to bottom of frame at 35psi and at 12psi on his BFG AT/KO 33x12.50's, and I'll do my 265/75R16 BFG KM2's at 35psi and 12psi and see which tire loses more height. On road at full air pressure I promise he's riding higher than me, off road at aired down pressure I bet I keep more height than him, and I know I'm running a MUCH heavier rig than he is too...

Metric sized tires most often come in D and E ranges, and it also helps when you have 16" rims. If you're going to run 33" tires on 15's, most likely they'll be C range tires.

Ahhh yes, finally the second reason for this thread. Up until now it's been opinions and personal preferences. Great, just what I hoped to see. Now, an actual side by side comparison. Outstanding. Now I can make a good informed decision on this product. Waiting for results,
Thanks. :kewl:

eh, yes but no, the 16" wheel makes some difference but, with the 265/75R16 (32's) I'm yet to find any less than a range C, and most are D and E (since it's a common tire size on some of the F250 Diesels...) If I bump to 285/75R16 (narrow 33's) most that I find are C or D. If I bump to an 18" wheel I find the same sizes in a C commonly, and a 15 I find them unrated or a C....but, across the board, 32's are almost always a grade higher than 33's from the little bit of digging I've done...granted, that was also when I bought my KM2's over a year ago, and stuff changes, but, I'm just sharing my experience....
If I can get GoBUFFS over here on my day off, or on a day when I'm off early enough to be able to do it, I'll do the measurements for ya'll...hell, if I can get the neighbor to come out and play too, I'll measure his 35's on his TJ....

When I was ordering tires (285/75/16), I found that my options for load range were always D or E. I never found a C range for that tire size. I still have my 265's on my X right now, and those are load range C. If you're serious about off roading (something I don't think has been mentioned too much), I'd want heavy duty sidewalls. None of those 2-ply sidewalls, I would prefer 3-ply, and reinforcement. And a 10-ply tread would be good too. But, I'd definitely prefer the heavier duty sidewalls.

odd, I don't remember what ones I found that were lighter.....
the km2's are reinforced 3ply sidewalls, and I'd say the heavier load range with better sidewalls is a great protection point, but, may not offset the stiffness of the tire which isn't as good offroad (handles wonderfully on road though)
a quick glance at tirerack reminded me on the lighter load tires...

My tires came in..... go 32s, go 32s, go 32s....holy hell what a stuff job. My 33 test tire did not fit the same as my actual tires.
Looks like a lambo where you can just squeak your pinky finger in all around the tire haha. Will post pics on my build thread this afternoon.
I'm bummed ....couldn't get duratrac in 33 so I went KM2 in 33 and I would trade in a heart beat for the Duratrac 32s already.

I tried to tell ya...just get to cutting and trimming!
Mine are bigger than 33s, and I made em fit. Barely. Of course, I did decide to add a BL (this weekend) just to be safe for a week of crushing it in MOAB next month...
