More footprint for better traction.

Less footprint for more psi on the contact patch.

Skinnier tires are lighter, less mass to start and stop motion.

If your running on soft ground or mud then wide is better. But on harder pack stuff (just like BH said) more psi on the contact patch gives better traction. If there where more choices in 10.5 tires I would choose to run them myself instead of 12.5.. Keep in mind that its easier to clear 10.5 tires then it is to clear 12.5 tires on alot of bodies...

Theoretically a narrower tire will give better mileage. I don't know if you would really notice, though.

I ran 33x10.5s on my last jeep and really liked them. Especially in the slushy snow. They seemed to cut through that stuff easier than my 35x12.5s I've got now.

Can you clarify for me the narrower higher psi concept?

The smaller the contact patch on a vehicle of the same weight, the more psi on the contact patch.

Unrelated to tire air psi.

I've always been a fan of the 'pizza cutter' tires over the fat tires on Jeeps, especially when running a smaller engine with less HP but higher RPM's. Interco makes a sweet 'special service' TSL Super Swamper in the 34"x9.5" flavor.

Put an elephant in high heels and the pressure under his "contact patch" will go up dramatically.

This is also why you sometimes see tractors with big wide rubber treads instead of tires. The tracks put less pressure on the dirt than the tires and cause less soil compaction. In certain situations, farmers prefer a very narrow and taller tire to cut down through the squishy mud to the harder soil below (like in a rice field that has standing water).

super swamper is about the only tire I can find in a narrow tire don't see many swampers on rocks ran a lot of them in mud do the hold up to rocks??

They hold up great is rocks as the TSL has a very tough sidewall. The TSL SX has the toughest sidewall they offer.

Check out the Q78, it's similar to a 36"x10.5" tire, what I run on the trail.

Im not sure how a narrow tire with more contact pressure is going to give more traction. Why use larger tires in racing?

Just depends on the conditions, it's not a steadfast rule.

Moke perfect example... racing tires are very soft compound (for one), but the start of every race they have to heat them up to get them to grip because they don't have enough psi on the contact patch to act properly. We don't have that option with normal off the shelf off road tires..

You grew up in the era that everyone jacked up the rear of their cars and put 60's and 50's tires under them and then thought their cars where fast because they could burn rubber down the entire block, but in reality they raised the back of the car up lightening the contact patch and then added wider tires making the contact patch even lighter per psi.

I don't know how many times we would sneak a 50lb tool box in the back of my buddies car before he went down the track and would actually run faster times because he was getting better traction (more psi on the contact patch)...

Same thing with putting weight in the trunk of your car during snow... You increased the contact patch psi and allowed the tire to bite down and increase the friction area...

Is there a point where you will go the opposite going to thin, you bet but I'm pretty sure you won't have that problem with a jeep between 10.5 vs 12.5...

Interesting. So why isnt everyone running narrow tires?
Perhaps to question the answer to my question:
Why arent more manufacturers making them?

No enough demand... Same reason new 4x4 trucks come with 22" wheels and 40 series tires.... People are more interested in form over function...
