#1013 of 1057 How Big ..... by mrmilkytou Feb 27, 2002 (5:51 am)
of a tire will fit under the wheel wells of a stock 2002 GMC Sierra CC, w/ the Duramx- Alli combo.(short bed single rear wheels) Right now I am riding on stock Bridgestone 245/85's and they ride great but given all the tire problems with the Bridgestone/Firestones I want them off and if I gotta get new I figure Bigger would look and maybe ride a little better. Anybody got some advice???? P.S. cspaulding, if they come thru and give you the DMax-Alli CC, I know you will be impressed. I factory ordered mine and it took 4 1/2 months to come in. It was worth the wait. The first tank I went 338 miles and filled up. Pump said 19.083 gallons. 17.71 mpg right off the lot. I can only hope it will get better. thanks to all who reply, Mr. Milky

if you go bigger than stock the dealer wont be able to do any warranty work for the engine/trans. There is a tsb saying if you install larger tires and are having any trans (shifting) problems you have to put the original size back on before they will look at it. This only applies to trucks with the allison trans I know i know its STUPID!

Thanks for the info. My hubby's boss had a '01 or '02 Duramax/Allison & went back to a Ford, he "gave" his to the doctor that raised him and says the guy loves it...he was getting between 17 and 19 for the few months he drove it, and they too figure it should only get better... As for me, after getting "burned" ordering our '00 in (if we would have been able to test drive it before we bought it, we would have NEVER taken the truck), I'll never order another one in. I'd even drive the 150 miles to Milwaukee to find one on a lot next time. I'm hoping Chevy gets their act together and we can get into the Duramax within 2 weeks. Thanks for the info. Chris.
#1016 of 1057 what happened cspaulding by mrmilkytou Feb 27, 2002 (8:46 am)
that you filed under the lemon law??
#1017 of 1057 Long list of problems... by cspaulding Feb 27, 2002 (10:03 am)
I had a discussion on 2000 K2500's that is in archieved discussions. Anyway...we ordered a 2000 K2500 crew cab, completely loaded, with a 454 engine. Waited 4 1/2 months to get it. Picked it up on a Saturday. As soon as my husband drove it he noticed the box was crooked, took it back Monday for that. He also told them it had a major lack of power, to no avail. At about 5000 miles it used 2 qts of oil. You could see oil around the valve covers and pcv valve, but the dealer had to do their dye test first. Also, a ticking in the motor developed...which proceeded to a knock and miss. Replaced gaskets & pcv grommets, but dealer still said nothing wrong with the motor. Also, that they noted the lack of power, that there was something wrong with the motor, but that it would cost us $2,000 to look at it - even though it was under warranty. Took to zone manager at another dealer ...got bogus story...radical cam, too many right turns, etc. By this time winter had come and I used 4wd (or tried to)...at times you cannot move the floor lever on the 4wd. To this the zone manager said "it locks in after you play with it on about the 5th or 6th try, you'll just have to live with it" and "it's normal". Also, the interior was falling apart, the locking diff. wasn't locking, and the brakes weren't working at times. Finally, a third dealer looked at the motor, replaced valves, lifters, cylanders, etc. at 14,000 miles. Now the tick/miss/knock is coming back and we're starting over with the same story. Believe it or not, this is the shortened version of what's all wrong with the truck. We've always owned Chevys and never had problems. Couldn't believe the run around this time. Hopefully the deisel will be better. Thanks for asking. Chris
#1018 of 1057 I had a ..... by mrmilkytou Feb 27, 2002 (1:04 pm)
1997 GMC Extended Cab, SB before my new truck came in. I was the 2nd owner, it was off a 3 yr. lease in January 2000. It sat on the lot for 6 months, no-one would buy it because it had a 454 and no 3rd door. Anyway I got a good deal on a great truck. It had 34K when purchased in July 2000 and it had 70K when I traded it in on 2/15/2002. The truck cost me a Hydrobooster, Starter, Waterpump, Battery and a door handle in repairs( probably about $1000.00 total ). It was not running as good as I thought it should when I purchased it. I have a friend who is an ace GM tech and he downloaded and updated program for me. The truck screamed after that update!!! I also had a slight cold start knock, maybe for 10-15 seconds. It used 1 qt. between changes and it got 12mpg in town and 14-16 on the highway with 3:73's. Sorry to hear about your troubles, I have personally bought 3 new and 4 used GMC trucks in the last 12 years and had good luck with all. It's too bad that the Dealer jerked you around. Sounds to me like the truck fell of the carrier or was tweaked when it was transported. Hey who knows maybe it was a Friday Truck!!! Lot's of Luck, don't give up on GM's yet!!! Mr. Milky
#1019 of 1057 we actually figure... by cspaulding Feb 27, 2002 (2:50 pm)
It was probably built on April Fool's Day, as we took delivery on April 14th - that's about the only explanation we can come up with. Our knock does it most of the time, doesn't matter if it's cold or run 100 miles. We have a friend who's an excellent mechanic (works for Ford, but knows vehicles) and he rode with my hubby last weekend. He said too that there is something seriously wrong with this truck. Even made my hubby pop the hood to make sure there was a big block underneath - that's pathetic. Chevy may be starting to screw with us on the lemon law deal too, so ...we'll see. I told them my attorney (boss) has been told if I get in an accident to sue the heck out of chevy, since right now the brakes are not always working (real safe, hey?) and Chevy knows it.

I am assuming you have a 4-wheel drive. I have an '01 Chevy 2500HD 4X4 ext. cab short-bed with the 6.0/4.10. I think the stock tires you have are 245/75/16, not 245/85/16. 245/75/16 are what came stock on my truck. They were the Firestone Steeltex. I just put 285/75/16 Cooper STT (mud tires) on American Racing 16x8 wheels. I had to crank the torsion bars up 4 turns (approximately 3/4" raise) and trim the front air dam and the inside front fender well covers on both sides. The left front fender well is quite a bit tighter than the right front fender well. I still get a slight rub under the left front fender well at the back when the wheels are turned sharply to the left. Trimming on the back side is a little harder than the front as the body and emergency brake cable are in the way. There is not enough rubbing for me to mess with trimming the back side and rerouting the emergency brake cable. There is plenty of room in the back without any mods. However, I would say if you have both the crew cab and the diesel, I would bet that your truck probably sets a little lower than mine in the front. Therefore, I would not recommend going larger than 265/75/16 unless you want to do some work. Unfortunately, the only lift that I have currently found for the Chevy/GMC 2500 HD's is a 6" lift. I was considering a 3" lift to accomodate the 285's, but so far the 6" is all that is available. That's a little too tall for me (and my garage). I am very happy with the Cooper tires so far. They were about $50 per tire cheaper than BFG M/T's. We'll see how they wear. I've always had the BFG tires in the past, which are very good tires. I hope this helps.

" was considering a 3" lift to accomodate the 285's, but so far the 6" is all that is available" Check out http://www.performanceaccessories.com they have a 3" body lift
#1022 of 1057 Thanks, but by whatsachevy Feb 28, 2002 (5:11 am)
I don't want no body lift. If you happen to see a 3" suspension lift, please post it here.
