First pics, quick and dirty... more/better after a wash and wax! It's EXACTLY what I wanted:

Thanks. I couldn't be more pleased with the way it turned out. No more "nose down" attitude and she'll almost pass for stock to the untrained. I'm calling it "stealth expedition-style." Here's before and after:

Thanks to everyone for their help and advice with tires, lifts, etc. I'm happy to report tire clearance in gobs, TPMS lights that dimmed on their own, and ZERO rubbing anywhere. No melt mod, needed to acommodate these tires, lock to lock.

Plus, I gotta give a shout to Revtek customer service and their product. I know there are a lot of shackle fans around but, FOR ME, their combination of spacers BELOW the top plate and AAL/shim out back was the winner.

Thanks for the compliments! I've been trying to contact rock rail vendors with zero success except Shrockworks (8 weeks out). No response from voicemail, e-mail from AJ's or NXrocks.

-TPMS-

So I'm driving back from lunch and the TPMS light comes on. I'm thinking that my luck has run out... the higher pressure these tires are running have finally tripped the sensor. I check the pressure and it goes 50, 50, 50, 27! My shop's a block away so they say they're going to check the seal. They think maybe there's a small leak in the seal around one of the weights. I should be good to go in a couple hours. (fingers crossed I didn't pick something up already)

Does anybody know the acceptable range for the TPMS? Or, does it just trip below a certain psi?


-Tire Impressions-

My impressions on this tire are very favorable, so far. Coming from an A/T, I knew there'd be more noise but this tire's been quieter than I expected. At highway speed, it's barely noticeable. My first light rip through the mud was as expected. I could definitely hook-up quicker and the shedding is awesome. I actually think this tire is very streetable if you're willing to take a little more noise and vibration from the tread at 35-40mph and under. Handling is just slightly more wander-y but that's to be expected with all that add'l sidewall.

I'm very glad I went with 33x10. I was really on the fence between those and the wider meats (285/75) but I'm glad I choose the 255/85.

That pic is a little misleading, the X is parked on slope down to her left. Plus the camera angle is a little womp'd. I'll have them check it out when I pick her up.

I think it also depends on the contact patch the tire creates. If the patch is taller than it is wide, as in tire width, it should hold a track better than a super wide tire that would have a wider-than-long patch.

FWIW, my stock A/T's were like magnets to the tracks in the pavement. If I was on the slope of the grooves at a stoplight, those tires would pull like crazy into the tracks. I haven't spent enough time on these new ones to see if it's more or less noticeable.

OK...

Do guys think I should have him re-do it for 0 deg.? I mean, those values are in a unloaded but settled vehicle. If I throw mom, baby, dog, and stroller in the back, am in negative territory?

Any thoughts?
Hmm, did you get the alignment before this picture?

It's actually odd looking the more I look at it...

if you look at both from and rear tires from the front, as in, looking from the front crouched down, but just off to the side enough that you can see the rear tire, do they line up vertically?

I know "eyeing it up" isn't an exact science or anything, but that's what I did when I put my camber bolts in and I was pretty close lol But toe was off..

Anyways, those figures you posted don't really look familiar. I just got an alignment a few weeks ago. I'll dig out my spec sheet when I get home and post up my results.

But no, you shouldn't get it set to 0 degrees as you're probably close to 0 degrees with you and someone else in it, or even you alone. Being slightly in the negatives when you're fully loaded won't really hurt anything because how often do you ride with a fully loaded truck?

If you think about it, with it set how it is now, you're alone most of the time driving in it right? So you're close to zero. Some of the time if fully loaded, you might be in the negatives slightly. But that's only some of the time.

If you set it to zero, you'll be in the slight negatives driving alone, then even more in the negatives fully loaded. So you'll ALWAYS be in the negatives instead of back and forth under and over zero (which gives you even tire wear).

I think you're fine.

According to the FSM the TPMS trips for these reasons:

- < 193 kPa (approx. 28psi)
- system malfunction (i.e. faulty sensor)

It is designed as a Low Tire Pressure Warning System. There is not an upper limit or range; per se. That isn't to say that you could fill your tires to 100psi and not have a TPMS issue.

The system will alarm for each sensor it recognizes as being below limit; 4 times when you air down for example.

Thanks, guys. The TPMS had fallen off the wheel in question. I'm all set, now

Yes, those pics are post-alignment, as shown in the print out. I think they line up fairly well but there's definitely noticeable positive camber out front, unloaded.

Keep in mind, those specs on my sheet are for the Off Road with the 265/75's and he adjusted me to the middle of that range. I suppose I could have him re-align me a little more to the negative (or close to zero) to compensate for the taller tire but we'd really be splitting hairs.
