#63 of 82 silverado 2500HD tires....
Feb 07, 2009 (4:03 pm)
i currently have LT245 75 R16 tires on my stock 2004 silverado 2500hd. i want to get a little bit bigger tires, i was thinking 285's although i don't want to get a suspension lift. i really just need to fill the wheel wells with more tire. the 245's just look to small. so, do i get 285's or 265's?? any thoughts?

Re post #47. I just bought an 07 2500HD Duramax Crew that has the same tires. I don't know yet what the rims are or what the lift is. Sure pulls our trailer better than the '98 K1500 did.
I don't feel the stability issues you mention other than the width seems to cause a pull to whichever side of the chain wear valleys in the pavement I am up on. Don't notice any pull on fresh road surface.
It is now almost six months later, have you resolved the problems you were experiencing?

I've got a 2002 2500HD CCSB 4x4 and run 285/75/16 with the torsion bars cranked up, not all the way I don't believe. I have never had them rub at all and did not trim anything and do drive off-road on uneven terrain
#66 of 82 Tire Wear or Cupping
Jun 30, 2009 (6:24 am)
2008 Sierra Crew Cab / 2WD / 21,000 miles - I have experienced some cupping on the inside of both front tires. The alignment shop said the truck is in alignment and it is a shock issue. The dealer says it is a rotation issue. On my 99 Chevy I rotated once every 15-20K without issue. The dealer says I should rotate every 6k especially with the more aggressive tire tread.
Any idea who is right?

It could also be a tire issue. Especially if you have those cheap Generals installed.
#68 of 82 Thinking of increasing tire & wheel size?
Oct 26, 2009 (8:31 pm)
I have a 2005 Silverado 1500 extended cab 2wd. It has the 5.3 engine with a 3.73 rear end. It came stock with 245/70/17 tires. An optional tire was 265/70/17. I am thinking about getting a set of tires and wheels from a friend who replaced theirs with some fancier wheels. The size is 265/65/18. They are from a late model Chevy Tahoe. They bolt on fine and do not scrub (have not driven with them). The old tires had maybe 1" of clearance from the torsion bar when you crank the wheel all the way to the side. With the new 18" wheels and tires, the clearance is down to about 3/8".
When you compare the two sizes, the 265/65/18's are only .79" wider and 1.06" taller than the 245/70/17's. When you compare the 18" to the optional 265/70/17, there is very little difference in size.
What problems might I run into by running the 18" wheels and tires?
I believe it will effectively lower my rear end gear down slightly to around 3.6. I don't know that that little difference will be noticeable as far as power or gas mileage?? Any problems with the transmission?
Any thoughts would be appreciated.
#69 of 82 Rating High Mileage tires
Nov 11, 2009 (12:41 am)
When I bought my 2001 Duramax 2500, the tires were old but I still drove another 23,000 miles on them. When I replaced them with E rated Goodyear Trackers, I got just 16,000 miles. The back wore out the center quickly, I understand this has to do with the torque, but the old tires still held up a lot longer. I need something more like that. I've noticed people have posted in other forums that "The tracker has to be the worst tire ever." Won't argue with that.
On an LT tire, how do I check the mileage rating? I haven't found the LT's to have the same ratings on them as the P tires do. I'd like to avoid P's on a 2500.
Oh, and the 2500 is one tough truck. The eucalyptus tree in my yard fell on it, and it took hours with a chaninsaw to cut it out. Drove fine afterward, not even much body damage.

#72 of 82 Spare Tire Size Variances
Jan 02, 2010 (3:35 pm)
Given that the dealer option lists provide the opportunity to select a different size spare tire, how much difference will not lead to damage?
The build list of my truck indicates that the original tires were 265/75R17 and the spare was 265/75R16.
This is an inch difference in diameter.
Is this a problem for the 4x4 system and what is the distance you can expect to go before damage is caused?
Over the weekend, a tire was terminally damaged by road debris about 250 miles from home. Was this too far to run the miss-matched tires? I replaced the tire at a higher cost than I could have at home as I was looking at “changeable weather over summit” that might have invited the activation of four-wheel-drive, which is another consideration.
So, the REAL question here is, how close is close enough?
