Gmt 800 Wheel And Tire Question?

I am planning on upgrading the wheels and tires on the 2006 GMT 800 4x4 ext cab that I bought a couple weeks ago.

 

I am still partial to the older styles, like the American Racing Baja rims. I still preffer more tire and less rim. I would go with 16s if I could, but I believe 06 was the year they increased the size of the front rotors and I am stuck with 17s.

 

Here the Rim I am using, 17x8 with a 0 offset / 4.5 back spacing.

I am still a huge fan of the BFG AT KOs

 

The combo I use to run on my early model (2001-2002s GMT 800s)was the same wheel in a 16x8 and I ran ATKOs in a 275/70/16 size. Those cleared everything with just a very minor 1/2 tweak of the torrsion bars.

 

This 2006 came with 265/70/16s, and I can get the same size tire for the 17" baja's that I had befor, they are 275/65/17s, that size gives me the same demmensions as the 275/70/16s that I had befor.

 

With the rim being larger, I am wondering if the 285/70/17s might clear, they are 32.7" tall vs the other 275/65/17 that were 31.2 tall. The OEM tires should come in at 31.8 tall.

What would be needed to clear a 32.7" tire that is 11"s wide, mounted on a 8" wide rim with a 0 offset?

Nice truck. I too like that style of wheel. Have you checked out the Mickey Thompson Classic II wheels? They are very similar except the holes are bigger and looks better IMO.

I like the mickeys too, however they are not available, with a clear coat or chrome plated like the ones from American racing . The Chromeplated AREs are the only low maintance ones that I have found in that style. The set of 16s I had on my old 02' GMC were american eagles, less priced knockoff the AREs. I liked the rims, they were just a pian in the rear to keep looking nice.

Anyone know the back spacing or offset of the factory rims.

 

The factory rims look ok, but the truck came with the OEM fender flairs, that make the wheels and tires look a little funny, from the way they are tucked in side the flairs.

 

I think the aftermarket tires and wheels will resolve the issue, just not sure rather to go with the 275/65/17s (31.2" tall) or 285/70/17s (32.7"tall).

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      My office is slowly filling with Blazer parts. Getting ready to do the big bang of repairs. Intake (second time), water pump, radiator, hoses, and I'm going to re-seal the timing cover where someone went hog wild with silicone. Might as well, because I don't think that's done right.   There's a local tow yard that I didn't realize also has quite the inventory of junk vehicles. This is an old school junkyard. No waivers. Cash only, you were never here if anyone asks. Don't piss off the owner, or you'll end up in the back of one of those cars, headed for the shredder. And if you see something, don't snitch. Cars stacked double high, wasps nests, trip hazards and junk everywhere. I found a few little odds/ends for my Blazer. The $20 I spent was worth the experience alone. But I was never there. What yard?   I officially love/hate this truck. It's so out of my wheelhouse, roughest vehicle I've ever owned. Every. single. repair. -is so hard-fought, everything that can go wrong, goes wrong. Currently in a hate phase, and kind of wish I was closer to sending it down the road with a lucky new owner, to be honest. Preparing for the day when I tear into this thing...lots of pre-funk with Ibuprofen.   Rock Auto sent me a bad reman rear wiper motor. It was a bear to install. The tailgate in these things has about eleventy-billion fastners and pieces and things that need to be uninstalled/moved just to access the shoddy rear wiper motor. The casing on mine was cracked clean through, btw. Nice, GM, nice. SO I got this new motor installed, hit the switch, I see it wig-wag (without the arm installed) and think I'm golden. Reassemble everything. With the wiper arm installed I gave it one final test. Time to clean up and take the other half out to dinner, collect a paycheck, right?   Nope. I hear the plastic worm gear stripping as the arm hung up. Just like my broken motor. Weak/old and shredding itself internally. I can assist the arm and the range of motion is normal, and it parks correctly. It just doesn't have the poop to actually sweep the arm with a blade on it. Oh, hell. Turned the key off and shut the shop door behind me. I get to do that over again, too.

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.
