No Allison.

M32 4L85E 4 speed auto

The Alalanche does not have the Allison but the brakes are the same. With a hitch change and E/H brakes we towed our 38' Sonic W/ trp. 500's through the hills to Lake Cumberland. The boat loaded W/ fuel and gear scaled @ 16,900lbs. way more than I was told. The truck did pull it well for 100,000 miles before going to a Cummins. Beware of having an accident though pulling something that overrated. I knew the agent (my wife)

WOW! 17K with a 2500AV! :eek:

Sorry I might be hi-jacking this thread but was wondering what tires are best for all types of season plus towing? We just bought a used 3/4 ton 2005 a couple of weeks ago and two of the tires look fairly new and the other two will need replaced soon. The two good tires or Ironman which I haven't heard of and guessing aren't the best tires so thinking of getting four new ones and hopping I can get some credit for the two good tires.

I ran BFG Rugged Trail E load rated and liked them.

If I were buying new tires, I would consider:

BFG All Terrain KO
Yokohama GeoLander AT/S
Michelin LTX

I have had great experience with Cooper tires as well. Others on here like the Bridgestone Dueller as posted in the past.

If you are investing in tires for a 2500AV, I STRONGLY SUGGEST going ahead and getting some 8 or 9 inch wide wheels. I can tell you from personal experience that the towing stability is DRASTICALLY better having towed with stock and 17x8 wide wheels back to back. Also, go for the rear axle spacers as well. I guarantee you will like the truck better with these two upgrades.

If you don't want to spring for wheels & tires, just go for the spacers for now.

I also don't recommend running different tires front and back.



(I ran my stock 16x6 inch wheels for only a few months. I then went to 16x8 inch aluminum wheels for a couple years with Cooper tires. I hit some metal debris and had a blow out on one of my Coopers on the 16x8 wheels, and opted to move up to nicer 17x8 inch wheels and tires. While waiting for my new wheels/tires to come in, I towed my 12K pounds to a poker run back at stock setup with the OE wheels/tires, and no spacers. I HATED IT. The truck lost 30% or more of its stability IMHO. I vowed to never put that setup back on the truck and sold the OE wheels/tires immediately. When you go from the stock setup to 8" wide wheels you are adding 33.3% more contact patch/tire footprint to the road. This is WAY noticeable. If you go to a 9" wide wheel, you are adding 50%!! more contact patch/tire footprint.)

SYD ive been looking for that exact truck!

As for tire, You want to look at the Yokohama AT/s, HT/S depening on your exact needed. My Lanch had AT on it quick nice looking towed well. Load D on them. A couple other choices out there but thats best bang for the buck also comes in White Letter or rev. it to make a black side wall for less maintance.

Harder and harder to find. I specifically sought out the LE because I didn't want to be 'just another black dually.'

I found mine on Cars.com. I was pretty excited about it when I got it as I knew there were only 2000 built ever, and that they were few and far between. Most of them went to Texas.
Only made in 2000 and 2001, and they all have leather and 4 doors, so you can narrow down your search parameters with such details.

Damn if there are not 10 of them or so that I regularly see in the Mid-Atlantic area, including another OSO member!

Thanks guys. I check and like I said the better tires are Ironman Radial and the other two tires are Falken landair h/t. Don't even know who makes it. Looking at discount Tires they weren't given a high rating. I was thinking of Bridgestone dueler a/t revo 2. Don't know much about Yokohama tires. I like BF Goodrich but they're kind of high and Michelin are also but it seems like Michelin's tread last a long time. I like Goodyear Wranglers but the only Goodyears they list are more mut tires. I take it you guys don't care for Bridgstone tires. I have a set on are care and they have been a good set of tires.

bridgestones blows balls along with copped. BFG's are a build from Michelins they are just another componey. Thats why the High tag on them. A great tire is like i said Yoko, Also General Grabbers do well with a great tag on them not to empty your pockets. Falking private label Asian build or korean depending on what model you buy. Continental tire builds the General line so it has a really good root it stems from.
-Mike Any question let me know. My dad owns a repair/tire shop i can get any info you want. Also those ironman tire junk no name off brand crap
