Hello, will bfg 285 KO's fit my stock wheels. I just have to put some larger tires on this rig. I know I must lift the front. Thanks, Den.

Many members run 285's on the stock rims, however, 265's are about as big a tire as most tires shops will put on a 6.5" rim. 285's tend to bow out the tread adn get excessive wear in the middle of the tread. I personally have 265's and even notice a little of this wear.

285s fit fine on stock rims. The only rubs that I had was on the mudflaps in the front (easily trimmed) and the fender liner on the front driver's side. You can either trim or reshape that easily. I also trimmed the front inside corners of the airdam (see signature). I didn't raise the front at all with the stock rims. I just put some eagle alloys on and I ran into a few more problems with rubbing, but nothing major. I had to remove the front mudflaps for now until I can crank the torsion bars and get it aligned.

We have the 265s also, when we bought them the garage showed us the BFG book and in fact the 265s are to big for the 6.5" wide wheels also.

:rant: It would have been nice if these trucks came from the factory with a bigger wheel and tire set-up. Wanting to put 285s on a pick up truck's stock wheel SHOULD BE A NO BRAINER. But instead the 245s are the only tires that truely fit the 6.5" wheel.:rant:

GM putting 6.5'" wheels on there pick-up trucks was a :badidea:

I have 285 revos on stock wheels.

Brad

I have found that Brand name (Sumotomo)correct spelling?
Are the thinnest 285/75r16 out there
they end up being 33.2 inches in diameter and are about 1/2 inch thinner than my buddies cooper 285's
mine are on stock rims whereas his are on after market 10"wide rims
try the sumo's.
Great wear and ride

I have 285 revos on stock wheels.

BradYou can mount them on stock wheels, does not mean they are made to be on 6.5". :o: If I remember, the book calls for a 7.5" to 9.0" wide wheel for the 285s.

I have the 285's on my Duramax and Avalanche, I have not noticed A

I have the 285's on my Duramax and Avalanche, I have not noticed any unusual tire wear on the Avalanche and have approx 15K on them. I only have 3K on the Duramax, so far they are wearing fine. I did go 5 turns on the torsion bars and that raised the truck approx 1" and then had the front end re-alligned.

yes

Another option is to run 255/85/16s. They are the same diameter as a 285/75/16 but are narrow enough to run on a 6.5 inch wide rim.

I have them on my truck...
Yes, I have to modify the drivers side splash guard, etc....

I haven't bottomed the front end out yet to see if they rub under compression yet...

There is quite a bit of sidewall bulge with the stock wheel.
I think I would have gone with 265s if I could go back in time.:rolleyes:

But, my fuel milage went way up because of the bigger tire. I can really cruise the highway at 2,000rpm now.
I reprogrammed the tire size with my Predator.
Pre 285s I never saw better than 17 mpgs on the dash computer. I saw 21 this weekend!

I'd like to put a Cognito lift on the front, and maybe a add a leaf in the back.

Thanks you guys for the info! I will look into the ideas you all gave me. Also they need to be D or E rated, I pull a 5th wheel.

I think D is the only rating you can get in the 285. I could be wrong. Although, the 285 D rating is about 3400lbs @ 65psi (BFGs). That is more than the 245s E rating IIRC.

I've got 285's on my stock alloy rims. The tire shop didn't say a word about it. I did have them turn up the T-bars a little, and re-align the front end.

To me, it's just not worth the risk..I know you can put that tire on the stock rim but it's simply not designed for it....You're putting yourself and your truck at risk doing it...The tire companies don't list the recommended rim sizes for fun, they do it for a reason...safety....Now, a guy can probably put a 285 on a stock rim and have no problems...but can everybody? If the truck is just driving around with no trailer and no load, perhaps its fine....loaded or pulling a trailer...that sidewall is bowed out way too much in my opinion on a 6.5" rim..
Do what you want to, but I firmly believe that a 285 belongs on no less than an 8" rim...
Have fun bashing the hell out of me..

Let The Bashing Bigin :D

The 3500 SRW comes with a 7" wheel if you can get a set they may help.
As far as tire weight rating, Les Schwab has the M55 in a 285/75R16 with a load rating of 3740# per tire, which is at the upper end of E rating or lower end of F rating.

Some say I'm CRAZY, but I have 315's on stock wheels. I have over 5,000 miles on them now with no problems.

HEMIEATER, sounds good but...
if i was going to go with 315s i would probably go ahead and get a set of H2 take-off wheels with the tires already mounted for about the same price as the tires alone.

These guys are exactly right when they say that they are not meant to go on the stock rim. You may not have any trouble, but that doesn't mean that you aren't tempting fate. I would seriously consider going to a larger rim on anything larger than 265s and even that is stretching it according to the manufacturers. They make tires for wheels every single day, i am sure they know a thing or two about it. If you think about it, if you were to put a big tire on a 4 inch rim, what do you think is happening to the tire, it is put under stress just to be placed onto the rim this way, the bead is not set flush to the rim, the center of the tire bulges. Anything that forces the tire to be flexed more than it has to be is bad, this creates excess heat buildup which is the leading cause of failure. (my father has tested wheels for many years and even the tread on the tires is buffed off as it builds up excess heat for the loads that the wheels are subjected to, and the tires are also very overinflated to prevent flexing) I know i am ranting a bit, but you could be okay or you could find out what it is like to have a tire explode because you like the way the stock rim looks.

What is the max tire size you can put on the stock wheel 4wd crew cab duramax/ alison without needing a lift? Seems from what I read you may be pushing it with 285's. this truck pulls a 9,000lb travel trailer.
Thanks.
