I finally got them on last night! They look awesome! Still waiting on the 5th to get here though. Next will be a lift, I know I want a Teraflex lift, just not sure if I need the shock absorber one or the more expensive one with suspension. Anyways here's some pics!

Sweet! I know you are glad to finally have them all mounted up! It also just hit me that you are going from 29s to 33s. You are definitely going to need a Procal.

A dealership can actually flash his computer to calibrate up to 32.1 tires. They can adjust the speedo up to this size but not higher. Since your new tires are 32.5 it's very close and will be nearly perfect unless you want to get the AEV it's not totally necessary. I did this and I have the same set up. Speedo is dead on with GPS and checked against another car driving the same speed.

I apologize for the leveling kit recommendation, I have been responding to several other "need lift now" threads about them and just spouted that out. If you are looking a BB or a real suspension lift. Teraflex 2.5 with coils and shocks is very nice and would look great with your new tires/wheels. You can get it for about $750 from most vendors here and save money by doing the install your self or with friends.

I got them installed at a Discount Tire shop an they did switch over the TPMS and flash my computer to calibrate it. So far so good, no warning lights lol. No worries about mentioning the lift kit. I was thinking one of these
TeraFlex 2.5" Lift Kits - Quadratec=

But was not sure what to get. I dont think Id want the cheapest one and since I dont really offroad that the second one would be good, but then why not be safe and go for the $730. one?
Also has anyone ever worried about not getting the lift kit put on by the dealer since it could possibly affect the warranty if something happens to the powertrain? At least thats what they were saying when I got the jeep.

I have the TF 2.5 coil lift with shocks $750. Here is a link to the install http://www.wranglerforum.com/f33/teraflex-2-5-coil-lift-install-pics-118697.html

If DT put on your wheels/tires make sure to check your PSI because they ship them at the max cold rating of 35psi and the shops will mount them up and not care. If yours are at this pressure, lower it down. The correct psi for your new tires is 28-30 max cold psi.

Well they didnt come mounted and balanced from DTD but DT did air them up to 35 PSI from what the guy sai last night. So if I let some air out will the "low tire" warning go off? of could I just have them reflash it?

You originally had 225/75/16 tires on it and the stock psi rating that your computer goes by is 35-37psi. If it has not gone off yet it may not still because your new tires are aired to the max right now at 35psi and will certainly go higher once you drive on them or when the temperature goes up outside. You're tires should never be at the max cold rating unless you are about to take on very heavy loads and need a little more cushion. Daily driving and wheeling do not justify having them at the max. In addition, you will cause your new 12.5 tires to wear un evenly and deteriorate in the center by being over inflated. Decreasing your psi to 28-30 psi is the right amount that will allow your tires to have even contact with the road and wear evenly. It is also more safe to do this as you will have a greater contact patch for better traction. Lowering your psi will cause you to have slightly worse mpg because you are moving a greater part of the tires across the surface of the road vs on the center portions when over inflated.

Your TPMS light will illuminate for a while once your set your tires to the correct PSI. It takes a while for it to read the new temperature and set it so that the light will go off but it may come on again regardless. It's a harmless but yet very annoying feature of the system when you go to bigger tires on your Jeep. The AEV procal tuner will allow you to adjust your sensors manually to zero or any desired level you want. Allowing you to go to any size tire in the future or run your current ones and at any level. Very helpful if you air down when going off road. I took the sensors out of my wheels a few sets back and the light has been on my dashboard ever since. I'm getting the tuner to set it to zero but I'm going to wait until I re gear and do a few other things. Not that big of a deal but the light is annoying.

You need to lower your tire pressure or your tires will shoot up to near 40psi for daily driving. Mine did, this is all from experience. :thumb:

Roger that! I'll be letting some air out of them around lunch time then. :) Which reminds me I need to sell my stocks tires/wheels now!
Im not sure if I could stand that light being on all the time though, i'd keep looking at it every 3 seconds!

Good point. But I believe my dealer charges over $75 or so to hook up and do that calibration, so I would just get the Procal personally. Though, it sounds like DTD did some form of calibration for him.
