#77 of 117 2001 2500HD tire size by levin1 Sep 10, 2007 (12:17 pm)
I have a 2001 Chevy 2500HD 4x4 6.0 liter 410 rear. Stock rims are 16 x 6.5 with 245 75 16 load E tires. Can I go to a 265 without any problems on same rim. Replies to this message: obyone (Sep 10, 2007 12:36 pm)

more info please
#81 of 117 It would be no problem in changing by obyone Sep 11, 2007 (5:03 am)
from 245 to 265 as long as the replacement tire has the same or exceeds your current tire speed and load rating. There will be a small deviation in the speedometer and odometer but nothing major. If you would like you could purchase an aftermarket programmer to adjust for the size difference or you could have the dealer do it for a small fee.   Don't know why other than cost that GM went with those puny 245s. Made the truck look kind of dinky.

#84 of 117 2007.5 Chevy Truck 2500HD 4x4 HELP!!!!!!! by gxsinc Aug 23, 2007 (1:33 pm)
I was parked on a slight hill on paved road. Truck was in park with e-brake on,engine off,no keys in ignition. I had a 16' flatbed trailer(maybe 1000lb of weight) hooked to ball of truck with ramps.I off loaded a small kubota tractor, When the back and front tires of the small tractor were on the road surface my truck and trailer started rolling down hill on its own.It started down slow for a couple of feet then gained speed,with all 4 wheels rolling. A friend of mine was standing behind the tractor saw the truck moving and ran after it , he barely caught up to it and opened the door ,jumped in,grabbed the steering wheel and slammed foot on brake.The truck did not stop.it started slightly veering to left(started to jackknife) and within 10 seconds or so was completely sideways with the trailer smashing into rear panel.The trailer actually when jackknifing pushed the whole rear of the truck sideways until the entire truck was crossing both lanes of road. the truck only came to a stop when finally nosing into a wall of dirt on other side of road.If the truck didnt jackknife and turn the trailer to stop on opposite side of road, the truck would have continued straight down hill and cross over a dual lane cross street and proceed over and straight down a 100' cliff with my friend in it.   HERES THE PROBLEM; WHEN THE TRUCK WAS ROLLING ON ITS OWN AND MY FRIEND JUMPED IN TO SAVE IT,THE ENGINE WAS OFF(NO BRAKES AVAILABLE FOR STOPPING)THE STEERING WAS LOCKED(NO CHANCE OF STEERING THE WHEELS)THE E-BRAKE WAS ON(DIDNT SEEM TO MATTER)AND NO KEYS IN IGNITION(WHICH IS NORMAL WHEN PARKING).   QUESTION: HAS ANYONE EVER HEARD OF THIS HAPPENING ?    DOES ANYONE KNOW WHY IT WOULD ROLL ON ITS OWN ?    WHERE CAN I GET PROFESSIONAL HELP TO TROUBLESHOOT THIS PROBLEM ?    "GM REFUSES TO TAKE RESPOSIBILITY AND SAYS THERES NOTHING WRONG WITH TRUCK(AFTER ONLY HAVING IT ON A AUTO RACK FOR 1 HOUR HOOKED TO A COMPUTER.)"   DOES ANYONE KNOW IF ITS ELECTRONIC,LINKAGE,TRANSMISSION OR TRANSFERCASE?    I JUST PAID 56K FOR THIS TRUCK 2 MONTHS AGO .THIS PROBLEM NEEDS TO BE CORRECTED.   IT IS UNSAFE TO TRUST IN PARK ON A HILL!   WHAT WOULD HAVE CAUSED THIS TO HAPPEN WITH A BRAND NEW TRUCK?

Replying to: gxsinc (Aug 23, 2007 1:33 pm) I would not trust Park or the Parking brake to hold a truck & trailer on a hill. With just a vehicle alone I was trained to point my wheels to the curb to prevent just such a happening. We were always expected to chock the wheels on a hill with a company truck. With all new vehicles and this drive by wire crap you are dead as far as steering and braking. I hope your insurance company is generous.

Replying to: gxsinc (Aug 23, 2007 1:33 pm) the transmission has a manual likage. its a little hard to "buy" your story. you are telling me that you had your truck in PARK with the E-BRAKE on?? they both failed???? i rebuild transmissions for years and NEVER seen a parking pall break on anything. IF YOU HAD YOUR KEYS THE TRUCK MUST HAVE BEEN IN PARK, ITS ALL TOO HARD TO BUY IM SORRY YOU JUST SCREWED UP THATS ALL. HEY IT HAPPENS TO ALL OF US NO POINT IN BLAMING IT ON GM
