SUMMITMAXLLY 09-10-2004, 02:42 AM I'll assume you still have the factory rims. I went with the Bridgestone REVOs 265. They fill the wheel well and have a fairly aggressive tread design but are surprisely quiet for an AT tire. Others in the group have gone bigger but I feel the 265s will not cause that much of a problem with the speedo and/or towing capacity.
Max Owner 09-10-2004, 07:54 PM I have 265 Michelin LTX M/S. Speedometer is out a little. The M/S is alright, but I think better can be had. I too am looking at the Revo for the next tire replacement.
No rubbing with the 265's. I have heard the Revo doesn't get great milage (wear wise)
Dnipro Max 09-10-2004, 11:20 PM Thanks, guys
so i would get 265/75/16? what if i go 85 instead of 75? would work also? and yes they will be going on factory rims.
Max Owner 09-11-2004, 12:17 AM I have 265/75/16. No problems. 85 series I can not say. Check with the tire dealer and see what the overall height is on both.
SUMMITMAXLLY 09-11-2004, 12:56 AM On the 85s, I think you may have to trim the front valance. If the 85s look like the ones I saw on the Fords, the tires are fairly tall.
rt446 09-11-2004, 07:28 PM I went with the 265 have 10k miles 5k towing I lost a couple of miles pre gal and speed is running 2 mph above speedometer. The dealer reprogram the transmission. Sure look a lot better. Had a friend who put the 85s on had to do the trim and later went back to the 265 said he didn't like them,.

CADMAX 09-11-2004, 10:43 PM I run the 285 on my 04 and had to trim the front valance. I have seen many of the 01's and 02's with 285's and no trimming.
You may have to crank the torsion bars a little. Maybe an inch. Also the 285's do not have the stiffness or as high of a rating as the 245's or 265's.
My truck actually rode better when I tightened the torsions 1 1/2 inchs and went with the 285's. My speed odometer is about 3 mph off and my odometer is one tenth off.
Dnipro Max 09-13-2004, 01:11 AM Thanks, I will problebly go with 265/75/16, cause they do look much better, what kind of brend is good for snowplowing and also for year a round drive, any one plow?

Max Owner 09-13-2004, 01:30 PM One guys truck I have seen (Heartbeat Canada) has BF Goodrich All Terrain's. He plows, and uses his truck in sled pulls.
JRKRACE 09-13-2004, 09:39 PM I used to plow with a 2002 HD with a set of Michelin 265/75-16 LTX MS with an E load range. Very nice tire. Super quiet. As for plowing, these tires were fine. I plow a lot of commercial and I have never been stuck.No rubbing of any sort even with the plow on....My 2004 may get the same tire when I set my new truck up with the plow..
Tom Cobb 09-13-2004, 11:45 PM I have Michelin 265/75 tires on my 01 and have no shifting problems or performance problems. Truck looks better with wheelwell a little more full. I compared the speedo to my GPS and around 65 to 70 MPH there is about 2.5 MPH diff. Actual speed is higher than speedo. I calculated the odometer diff to be 3.8%, less than what GM says is acceptable. They say 4% is the acceptable error.
The total odometer error may not be that high but have not had a place with a measured mile to check it. At 40 MPH the GPS and speedo are the same. It appears to be a function of the speed at which you drive. I calculate my fuel mileage taking this error into consideration. I add the 3.8% error to the mileage on the trip meter.
Go for the change in size. No real problem.

Dnipro Max 09-16-2004, 11:52 PM Thanks, my choise is 265/75/16, but still will have to chouse between different brands, any other sugestions?

DaleM 09-17-2004, 03:00 PM I want to go with a 275/70R16 but if I could get a 285/70R16 on the stock rim and not have to trim I would rather do those. My question is could I crank the torsion bars enough to level out the truck and get the 285's on it without trimming the valance?http://www.dieselplace.com/forum/smileys/Confused.gif

I think that you can. People put the 75 series tires on and said there has been no rubbing.
DaleM 09-17-2004, 07:19 PM I have been looking all over the place at tires and will someone explain the intricacies of the tire sizing so a moron (like myself) could understand them. Is a 285 taller than a 275 and is a 70 series wider than a 75 series? In which case would a 285/70 be taller and wider than a 275/75? Please explain and if so put it in inches of height and width. LIKE THE OLDEN DAYS! Thank you!Edited by: DaleM
TheBac 09-17-2004, 08:31 PM Dale, use this calculator to compare sizes:
http://www.1010tires.com/tiresizecalculator.asp
It also has a glossary of terms.
Take 285/75/16:
The 285 is the Treadwidth, in mm, or 11.22 inches (25.4 mm per inch)
The 75 is the Aspect Ratio, and is a % of the treadwidth. In this case, the sidewall height is 75% of the treadwidth or 213 mm or 8.4 inches
The 16 is the rim width.
The 285/70/16 would be wider than but shorter than the 275/75/16.
Then you get into load ratings, speed ratings, etc....
Trust me..you ain't the only "moron" here!!! I is one meself, just ask anybody!! http://www.dieselplace.com/forum/smileys/Big Smile.gif
