Price: $500.00
Pros: A quieter ride than I expected, wear/treadlife has been good even with lots of road driving. They self clean okay (could be better...) and seem to work alright on wet pavement.
Cons: A pain to clean due to sidewall design. They seem to "grab" road imperfections and I really don't like how they perform in the deep fluffy stuff, they tend to dig to the bottom and leave you stranded on top, typical for a mud terrain but made worse by the sharp tread blocks. NO STUD HOLES
Recommended? Yes

Comments: Great tire, I would buy again. The price was right and these tires look very agressive and will tear *** and bite when they need to, but generally are a liveable street tire otherwise. I chose them over BFG All terrains due to the rim protector, the better sidewall protection, more agressive tread, and similar pricing. They also balanced very well and roll smooth and wear even, something i was afraid of buying MT's, and makes me glad I avoided cheap ones.

Pros: Great look,
Cons: none so far
Recommended? Yes

Comments: I was lucky enough to find a blemish set so i saved about 80 bucks per tire. So far I love these tires. they are great off road and still aren't extremely loud and seem to be wearing pretty well on road.

Price: $1,252.00
Pros: Low road noise, hook up to rock well, hold bead aired down well
Cons: Not great in mud (dont clean well) but I hate mud anyway
Recommended? Yes

Comments: They do very well on the road with little noise and good wet/snow traction. Hook up to rock very well, and hold bead at 10 psi without bead locks. Great tire. My size is 35x12.5x17, 5 tires cost me $1252 out the door, brand new. I'm considering these, the Maxxis trepador, and the Goodyear MTR/K in a 37"

Price: $600.00
Pros: Quiet on-road so far, excellent traction and digging properties. Decent in light snow, digs down to the road. Handles well, rides good, wears good on the street. Awesome looks. Great offroad on the light trails I've had it on.
Cons: No stud holes. Digs too aggressively in deep snow so you get stuck... Not so much a floater without airing down a bunch, to where you need beadlocks.
Recommended? Yes

Comments: An excellent all round tire that seems to be on the verge of being an AT with the quiet ride, and decent handling carachteristics. Its a good looking, good performing, reasonably priced tire that in my opinion is very streetable. The road noise so far has been acceptable, even pleasant. I

It lacks stud holes. Otherwise I would have rated it excellent. I am still very happy with my purchase.

Price: $220.00
Pros: Long life. Beefy side-wall. Clean mud well, do pretty well in the rocks. Relatively quiet for a mud terrain. I like the sidewall blocks.
Cons: Not as much sidewall flex as other tires.
Recommended? Yes

Comments: STT's are a great tire for the DD. They have a stiff sidewall that dosent flex as much as I would like in the rocks, but still handle them pretty well. Aggressive sidewall blocks. Lasted 65k miles. Not too loud for a mud tire.

Price: $200.00
Pros: Look great. Ride great. Have a nice whine to them onroad, seem to do fine as weekend warriors and get us the thumbs up from other Jeepers.
Cons: None so far. Will update if anything comes up.
Recommended? Yes

Comments: So far am very impressed (see Product Pros above).

Our tires are 32x11.50x15 (on stock Jeep Canyon wheels) and have plenty of clearance between the top of tire and fender, which should allow us to actually use the Zone Offroad 4-inch lift suspension lift for suspension purposes instead of just trying to clear larger tires.

There are no rub issues up front but in the rear I can barely fit my pinky finger between the inboard sidewall and the upper coil spring perch. Will need to install at least a 1.25-inch spacer prior to airing down for offroad - but that's not the fault of the tire.
