hey everyone

Im in montreal ,canada

I have a 2wd 2008 lmm with g80 diff

I tow a bumper flatbed trailer

I have 4 winter tires on it lt245/75/r16 with 60-65 psi

When I have to launch, the rear tires spins and I can barely get going

Is there a way to have more traction ??

my winter tire are Arctic Claw Tsi

Have you tried starting in 2nd gear?

thats true ill try that its suppose to drop 10 cm of snow here this night ill try it tomorrow

ty

65 seems kinda high, too. I typically run 55 in the rears all year long, with no heat or funny wear issues. (this is on 2500/3500 SRWs with both Lt245 and Lt265 LrE tires).

Your snow tire may have different requirements, but I'd check into that, too. And, I wasn't being a smartass about 2nd gear. It is a feature added to these trucks for just that purpose.

I tow a lot heavy stuff cant drop lower than 60 psi

To me it is amazing how bad the 3/4 ton trucks are for rear wheel traction. I have owned both Ford and Chevy. Sorry, I don't have a suggestion other than weight over the drive axle and lowest tire pressure the load will allow. But you know that.

650 ft tq at 1600 rpm does bad things for traction alright....my 05 avalanche was awesome in the snow...had 330 ft tq way up high in the rpm band though, and is the difference in traction during the winter...

put some weight over the axle, like a plate of steel or something else along those lines.

the best thing i ever used for weight was i took a old semi intertube a 10.oo x 20 cut it by the stem all the way through take a big ziptie and ziptie close one end fill it up with sand in the other end about 3/4 full and ziptie the other end closed it is going to be heavy you will need a couple guys to help get up in your truck and put it long way by your rear axle do two of them one on each side what is nice about the tubes is they dont slide around hope this helps

Add about 4 fifty pound bags of sand behind the rear wheels in your truck bed.:) This will give you more traction and you can use the sand to help you get out if you get stuck.

That's a good idea. Like stated previously, you need to put some weight in the bed. 200 pounds or more and you'll probably be able to notice a good difference.

I plow my place in Vermont with a 2 wheel drive and automatic chains.
if you have the trailer loaded I wouldn't think more weight would help much.
stopping it might be fun.

How do you start out in 2nd gear? I have the 6-speed allison LBZ?
Thanks

LOW TRACTION MODEVehicles with the Allison transmission are
equipped with a Low Traction Mode that
aids in vehicle acceleration when road
conditions are slippery, such as ice or
snow. By selecting 2nd range using the
Range Selection system while at a stop,
the Allison transmission will limit torque
to the rear wheels after it sees wheel slip
to help prevent the tires from spinning.

Borrowed from here http://www.allisontransmission.com/servlet/DownloadFile?Dir=publications/pubs&FileToGet=SA5521EN.pdf , something most people never read, even though it's in the owner's manual portfolio:rolleyes:

Thanks for the reply. I would have read the manual but since I bought truck used didnt come with it. I look forwards to trying this out when it snows again.

ok another 3 inches of snow here

I have the multi mile artic cla xsi tire on my 2wd 2008 2500hd diesel (g80)

i tow a trailer

I can barely move the trailer even when its empty

the 4x4 does make that much a difference in these conditions w/ a trailer??

What do you guy suggest me ??

http://www.tbcprivatebrands.com/images_tires/ArcticClaw-XSI.jpghere is my tire rated E

Yes 4WD makes a big differance. Can you get some studs put in those tires or even get studded tires up there? That would also make a world of differance. If not adding weight is your only choice with 2wd add 500lbs or as much as you can without being over weight with your trailer.

Add about 4 fifty pound bags of sand behind the rear wheels in your truck bed.:) This will give you more traction and you can use the sand to help you get out if you get stuck.

I use wood pellets - 12 40lb bags.

although I place weight in front of & over the rear axle - not behind....too much weight on the end of the pendulum - if it starts sliding out.

I have problems with wet roads in my area especially going from a stop up hill. The truck puts so much torque to the rear wheels it just spins the tires. I have to put it in 4 hi at a stop light/sign if I know I have to go up a hill.
So 4x4 makes a difference for me w/o a trailer and definitely w/ a trailer in these conditions.

When I had an old '95 Ford 2 wheel drive, I would put 2-4x8 sheets of particle board in the bed. When those suckers got wet they expanded and gained twice their weight.
The nice thing was I still had use of the bed w/o sand bags in the way and the weight was distributed throughout the bed.
Along with studded snow tires the truck went a lot of places I was surprised it went in the Northeast PA winters.

I picked up 6, 60 pound bags of sand at Home Depot (360 pounds) and it made a big difference. Still wish I had some actual winter tires though.
