Probably not what you want to hear, but a friend of mine put 235-85's on the same truck as yours. They are a little narrow, but it gives you the 33" height of the 285's and fits on the stock rims. Plus, no rubbing even when using chains (for mud) for those northern Nevada hunting excursions. Not sure on the load ratings though.

 

i have 265's on my truck and imo there the perfect size and i dont ever have to worry about overloading the tires (the truck is a different story though)

anyway here is a pic. and might i suggest these tires! there pretty nice.

Thats a nice looking truck, the 265's look good on it.

Yeah those are nice tires but do not do very well in snowy or muddy conditions. We run those on our work trucks because of the high mileage they get out of them. But the drivers complain about the poor winter traction. Plus they are very spendy, about $190 a piece around here.

I work at a tire shop and it is way easier to put on 265's than it is to put on 285's. If you want to make the 285's fit you need to crank up your torsion bars and trim the fenders a bit.

I have had both 305's and 285's on my 03 GMC HD. I needed to trim about 1/8th" of my front air dam. (the part that rolls back around to reinforce itself) and nothing off my fenders.

On the 1/2 tons and light duty 3/4's, I'd bet you'd need to crank the t-bars to level the truck and you should be able to get away without trimming. 265's still look too dinky.

 

I work at a gmc dealership and we install a lot of 285's on the hd's. I installed a set on a 2500 non hd and had to max out the torsion bars and it was still very close. I would go with the 265 on the non-hd. I have 305's on my 2500hd with 8 inch wheels, had to trim the front airdam/bumper area.

Good luck

 

235/85/16s aren't 33". You want to look at 255/85/16s. I run these on stock rims in the winter and 285/70/17s in the summer on an HD. The 255s are slightly taller than the 285s.

 

One of the guys i work with has 285's trxus on a non HD and they fit fine. Comming up to marquette any time soon? Want a price on em?

 

I have the 265 BFG's on my 02 2500 sub....... Discount tire would not put back ont the 285's I had wore out, they said the rim is to narrow.... even though they put them on in the first place.

.... the 285's fit fine with a small rubbage when at full lock........

 

I think with as narrow as the stock rims are i'm better off with the 265's. Plus then I can get the proper load range E. Looks like its spit if the 285's will fit. I think with a quick trim of the front air dam they will fit perfectly fine. But with 16x8 rims with a different offset might be a problem.

 

ive got 285/75's on my 98 2500 with no torsion and they fit just fine, i wheel it pretty hard when th fj40 is down jumped it a time or two and only polished a screw head on my fender flares once when your a half turn and hit somethin itll polish the screw head, just havent had the time to torsion it up.

 

i'm gonna replace my tires on my 02 2500HD with the 6.0 and 4.10's soon, i'm debating between 265s and 285's, its not fitment i'm worried about it gearing and towing. How much will 285 change my gas milage over stock(with 245's) i assume it may help since it will keep my rpm's a little lower? What i'm really worried about is towing though; used to when i pulled my jeep with a half ton with the 5.3 3.73's and 265 it would drop to 2nd gear pulling my jeep up hills on the interstate. My 2500 has never done that, will changing to 285s make my truck have to drop to 2nd on interstate hills when towing like the half tone did or should it still be able to hold 3rd. I love the look of the 285's but not if its gonna screw up my towing ability too much.
