View Full Version : 265 or 285

10-04-2011, 03:50 PM
I'm looking for some tires for my 1500hd 4x4. The stock tires are getting wore out and I can't decide if I want 265/75/16 or 285/75/16. What do you run on your HD's? I like the look of the 285 but not sure if I'm going to have to trim or not. Opinions please.

Well first the 285 cost more, will decrease your gas mileage and will make your truck sit higher which raises the center of gravity thus reducing your trucks handling. Taller tires usually causes the driver side seat to wear as well. Not to mention your spare is going to be a different size. You will also need a different size on your drop hitch, and your speedometer will be off.

Last but not least the taller tires will make your little baby trailer look even funnier when you pull it.

I'm sure there are more, but you get the picture.

I've got a 1500hd with a body lift, I dont think the 285's would fit without the lift. I just stepped down from 305 to 285. Went with a highway tread over all terrain, what a difference. Go buy some nitto dura grapplers.

Btw, do you realize the 285's are 33"

From what I've heard, 285's will fit might have to crank the torsion bars.

There is also 255/85's

I've heard good things about that size but the only tires I can find in that size is bfg KM2(mud terrains). Are there others out there that I don't know about?

I had 285's on a 2 door Tahoe. Fit ok but wouldnt do it if its a plow truck.

Mainly going to see city driving and hunting paths during the fall and winter. Nothing really extreme offroading b/c I don't take my truck into the deep stuff or deep ruts. Just the paths get slippery. I had my stock tires (245's)in it last year and didn't have a problem and they are highway tires. We get 1-3 measureable snows a year around here. just wondering how much rubbing if any I will get.

i have 265s on my 2500HD. i wanted 285s but didnt want to pay more for the tires that get worse mileage

Are you running stock rims? Aftermarket rims is when you run into problems. If you have stock wheels 285s are fine. I had 285s on stock rims, cranks the torsion bars a little(not all the way) no cutting. I recently put 20x10s same height tire with a wide offset and had to cut alot. A friend of mine had a chevy on stock rims running 315s. Is yours chevy or gmc? Chevys bumpers are different than gmcs. gmcs have less room = more cutting.

Just put a set of Michelin LTX M/S stock size 245 75 16 on my 2500hd yesterday. They feel a good bit better than the Bridgestones I had and a heck of a lot better then a set of Coopers I had. I hope to get more than 30K out of the Michs. Barely got that out of the Bstones and maybe got 20-25 out of the Coopers.

Yes, I balance/rotate every 6K and front end is not out of wack.

The 2500HD's do great with 265's. It's the tire they should have used from the factory. The little 245's don't have the weight capacity that the 265 offers.

Michelin LTX M/S is an excellent (pricey) tire. I have run several sets over the years. They ride better than any other tire I've used. They do get a little hard as they age/wear.

Its a Chevrolet. My cousin just bought 285/75/16 Michelin AT2 on his 2500HD (like a 2010) on stock rims. He said he had to crank his torsion bars about 4 turns. He owned my truck before he traded it and then I bought it and he had 285s on it and he said if he remembered he cranked t-bars 4 turns.

Load Range E on my 245s. Now most of the 2500s come with a 265 since around 2008 after the new body style change. I have seem some 2010 and 2011 with 245s though.

Oh he also said that he has found its better to pay a little more money for Michelins b/c he's gotten atleast 70,000 miles out of each set he's had

I stick with the 245s on my 2003 Silverado 2500HD.

70K would be great for me. That would be twice the miles I got out of my last two sets of Bridgestones combined.

I put 305s on 2500hd, just barely cut the valence.. it still looked like it was setting stock..

Those wore out so I put a set of 285 Nitto Trailgrapplers on it.. they set on there just fine.. I am gonna turn the torsion bars and squeeze 305/75s or 315s under it next.

I turned the torsion bars tho.

the 1500hd has the 8 lug rims ? run the 285 on the stock rims the trimmimg run have to do is so little it takes like 2 secs with a grinder, its the very corner of the air dam and like a inch of the inner plastic wheel well.....

ive have 285s on my 2500hd and now 315/70/17 on it now with no lift or cranking the bars just a little trimming
