Torsion bar keys in an Autoride truck?

[Dusty_Tahoe]

Recently sold my Tahoe for an 02 Suburban, this Sub has autoride with no issues (fingers crossed) but I want to at least put on some taller tires.

Can I still add new keys to the truck or will that mess up the autoride?

Would prefer to get an answer from someone who has done it. Asked on TahoeYukon and got "Sure why not" which wasn't very confidence inspiring

If you have full autoride (Z55 RPO code) you can do it you just need to be pretty precise. Buy 2" shock extenders for the front end, and crank the bars to 2" over stock. The sensors are in the shocks, so they won't know the difference. No need to buy keys since you will have the adjustability for that in stock keys, and you should be buying longer shocks or extensions anyway to get that down travel back.

Just measure a few times from a few spots so you have good reference points, crank, measure, crank, measure.

I have these sitting in my garage to put in this weekend.

Would it be better to use new keys though? I already have them from my Tahoe, obviously if I replace the shocks with new ones that would trigger a service autoride message wouldn't it?

It does the same thing, new keys just let you lift further up. If you replace the shocks with normal ones, yea, you'll get an code.

Gotcha, now next question, since I can't really do an actual lift with the autoride, I want to go with a thinner, taller tire. I'm considering the cooper ST maxx in a 255/80 17 or alternatively 285/70 17s.

Tires will see daily driving and regular beach trips. Right now my stock 265s are doing well aired down on the beach but I do need to replace them fairly soon. I'd like to avoid any trimming, rubbing, etc. hence the reason I'm leaning towards the pizza cutters.

285/70-17s are really common and the size I'm running. You'll be able to fit them easily, minor trimming of the plastic inner fender liner with a razor knife may be needed depending on your wheels. Not sure what beaches you're running but I wouldn't want pizza cutters on a 5000lb+ rig.

Mostly Democrat Point, Sore Thumb, I wanted to try to avoid doing any trimming at all, plus the lighter tire shouldn't hurt my fuel economy as much. The highway tires I have now seem to be doing pretty well, will 10mm make that much of a difference even when aired down properly?

Ah, yea, so local stuff to me too. If you don't want to trim at all, you need to stay with the stock size tires. Even a skinnier, but taller tire will rub the plastic inner fenders when you turn. It really isn't any big deal to trim, and not noticeable unless your head is in the wheel well. But it's your truck, your call.

You can also buy the new KO2 in 34x10.50r17, or there are the 235/85 and 255/85 options on the stock 16's.

I'm on 17s since I have larger brakes, wanted to do a 33" tire at the largest.

So you installed the gmt900 brakes? And the 34x10.50's measure closer to 33.5 and are lighter than most metrics.

Yea I have GMT900 brakes, and interesting I didn't know that, will look into it more

Edit: Nevermind that's way out of my price range, I only paid $900 for the whole truck.
