Matador Rics, your Jeep look awesome man, great job. The more I look at photos of 2-door Jeeps, the more I feel that 33" is the best size tire. 35" look too big for a 2-door IMO. 35's are more suited for a 4-door.

VaderJK12 I am about to install my setup today, the Duratracs came filled at 35 psi. So for a JKU, 33 or 34 psi is best?
04-01-2012 07:19 PM
ESP Yep I'm thinking the wear is pretty much the same for me running them at 32 and you at 34-35. Its mostly 10 like you say. I've lowered it down as mentioned to around 28-30 and it really felt different. Much more sluggish and resistant when coasting and getting up to speed. I'm thinking 32-33 tops is perfect for these on a JK and 33+ on a JKU is gonna get the best results.

Now back to checking DTD and tirerack to see when those BFGs get back in stock.

Plus it just means we can all get those 35s sooner!
:rofl;

Let me ask you this: Where are yours wearing? Does your wear pattern go all the way across on the surface of the tires including the edge tread pattern, or is it more on that center tread pattern? I'd say 90% of my wear is on the center tread pattern--in other words, pretending the tire is a true 12.5" wide, the vast majority of my wear is probably on the center 10".

I am thinking 32 PSI is a good compromise to keep the pressure up for better MPG yet get a little better tread wear

I'm getting the very best wear and fuel economy balance with all four at 32 cold. Check them regularly and drive slowly. It's a very comfortable ride at this psi.
Mine are 30 now.....going to bump 'em up to 32 now. Thanks guys!
04-01-2012 06:35 PM
RedBones 32psi it is.
Thanks.
04-01-2012 06:33 PM
RedBones Well just put mine on Sat and damn it is rough. Got from DTD already on the wheels. Going to check paid tomorrow before work. Wanted to know what every one was running before I go tomorrow.

rics1997 IMO the Duratrac 33X12.5X15 (does not apply to any other duratrac size) should be in a range of 28 to 35 psi. 28-29 would be the smoothest ride yet may decrease MPG's slightly and may cause outer tread wear. 30-32 would be the mid range best for tread wear. 33-35 will make the tire a little stiffer but with this tire it is hard to notice and will give slightly better gas mileage but may also cause center tread wear.

The 33X12.5X15 is the only one in the Duratrac line that has a 35PSI max rating. All other Duratrac should be run at 35psi minimum

Truthfully, these DuraTrac 33s on 15" wheels are so light I'm not convinced the bumpstops are necessary, but they're like $15, so might as well toss'em on.
Yep, they just squished down. Don't ya just love my high-tech choice of words? lol

Do people recommend the Daystar Tailgate Bump Stops? And are they plenty long enough for the 3.75 bs of the MB's? If too long are they easy to trim. The way they are designed they sort of look like they aren't to trim friendly.

They trim very easily, just need a utility knife. Make sure you cut em about 3/8" longer than your measurement, so the spare will snug up against them really well.

EDIT: Like LitleMs said, you probably won't need to trim yours @ all. Mine were w/a bs of 4.5".

I have the MB TKO's with 33x12.50x15 Duratracs. I also have the Daystar bump stops. Mine fit and didn't need to be trimmed. Even if they're a bit too long, they're just squishy enough with that big tire pushing on it, that they don't have to be trimmed.

Come on we all know your jeep couldn't get that kinda MPG even with those pretty new shoes.
