Has anyone had similar 255s and 285s on stock width wheels? Probably a long shot…

Looking for input on differences between the two sizes with handling.
I had 285s on the old GM alloy 8 lug rims from the early 2000s. Along with a zillion other people. I believe those rims are only 6.5 wide. Had no issues with handling or otherwise, with proper tire pressures.
And as I recall they didn’t balloon too horribly.
Of course you’re aware of proper or recommended rim widths vs tire width and how it affects things.

Yep, I’m finding the problem is finding a shop that will install a 285 on a 6.5” wheel.

Edit: I found an independent shop that will do it.

I've run a couple sets of 285's and now also a couple sets of 255's on our '00 Suburban 2500 with the factory 6.5" wide wheels. Really no handling difference that I can tell.

Calling around and no one will really mount a 285 on a 6.5” wheel anymore. This may be the impetus to finally get a tire machine.
I believe those need to be mounted on 7 to 8 inch, preferably 8 inch rim

ko2 285s on stock steelies on my 91 squareburb 3/4 ton 4x4, they're getting pretty old but are still smooth and quiet, it spends 99% of its time on pavement in the south

it normally runs 40-45 psi every day, but if i load it heavy (more than 1k) it needs a lot more air in the back to keep from wagging on the interstate, 70-75psi and it's good to go, think my max is close to a ton on a few occasions

any more than that and i'll wake up the diesel dodge dually (soon to have an older brother 78 3+3 dually) or the deuce and a half

Americas Tire was not listing the Toyo M-55 as 3pmsf rated, but they are and they are available in 255/85-17.

Anyone with Toyo M-55 experience?

Seen a lot of them up on the N Slope. Haven’t used them in greasy wet snow though. I’d expect about the same snow performance as they give it….ie not as good as a AT3, because it has less siping and to my understanding it’s a harder compound rubber. They’re made to be tough not squishy.
But imo they’re a great option for a semi aggressive tire that doesn’t “look” aggressive with the typical big sidewall lugs on most AT/MT tires these days.
They’re have great/exceptional tread depth when new and should wear like iron. (I always consider it a free bonus if you get a tire that has 18-20/32 of tread depth vs the more typical 15-17/32. lol)

Some of those old M55s squirmed a little when new because of the tread depth. Wear ;em down and they will go forever. Old guy used to come into the shop with an f150 had over 80,000 on his.....hard hard hard!!!

It’s the wear forever part that don’t help in the snow (and rain). If they’re still built the same, they have a harder compound tread than most other LT tires. Great for tire life though.

Understood. My Mickey Thompson Baja Boss ATs seem to be on the opposite side of the spectrum. I suspect I’ll only get 30k tops out of them on my older Ram.

One of the reasons they do fairly well when the temps drop.

I just put a set of the Falken 255/85 MT's(E load rated) on my dually. I previously had 305/70's. Never any problems with the 305's except uneven wear due to being mounted on such a narrow rim(dually wheels are 16x6). Discount Tire wouldn't mount the 255's because they spec a minimum 6.5" wide rim, but all the local tire shops had no problem with it. I'm still getting used to the look of the skinnier tires - the 305's needed a spacer on the rear & stuck out of the fenders a couple inches while the 255's are completely covered.

If you can stomach doing business with Walmart… Goodyear Wrangler Authority in LT265/75r16E. Run them at 50psi for a full contact patch. 3 peak rated M55 style tread, wear like iron, grip like chains. I use them on both 1/2t srw and 1t drw trucks. Have 7 years on the current set, blew out an inner drive and had the 1/2t tires swapped to the dually rear axle. Don’t even need 4wd in sw TN snow/ice up to 6” deep. Still at 60% tread depth…
