Just put 265/75/16 Goodyear Wrangler Ultraterrain AT’s on my 96 K1500, OE tire was 245/75/16. These went on original steel wheels. Yes, I know some feel the 265 is not recommended for a 6.5 wheel, but Discount Tire Direct did have them listed for a 6.5 wheel. Just wondering what guys are using for psi? Shop sent them back with about 40 psi.

A TOTAL LIE !!! I have the Michelin 265/75/16 10 ply load range E, LTX radials on all 7 of my trucks. What uninformed person told you that, when a Z71, came with the 16" wheel, 6.5"wide, and was the standard on them???? I run them at 50 psi.

Look up 265’s on most tire sites and virtually all have 7” as a minimum for them. It’s not like some uninformed person said this to me either, Google it, bunch of threads on it.
Also the Z71 had 7” aluminum wheels.

Now, obviously, I’m ok with 265’s on a 6.5 wheel since that’s what I used!

Yeah, people do whatever they want, as I did. But to suggest I or some “uninformed” person came up with that is patently wrong. And Z71’s did have 7” wheels. Many tire shops will not mount tires that don’t fall into wheel range. All of this was beside my point anyway, as it was only mentioned because many would say it’s the incorrect tire for that wheel.

My truck came factory with 265s on 7" wheels. I doubt a half inch of wheel width is going to hurt anything.
Yup, and I put them on my truck too, so I guess I wasn’t concerned either.

That whole cant be done/shouldnt be done thing seems to be ancient info that has made its way into the database of tire stores.
They arent telling you it cant be done because of some particular knowledge.
They are telling you it cant be done because the computer says it cant be done.
When i bought my k2500 it had 265/75/16 pegusus tires.
I think they were walmart or something like that.
Just squishey cheap garbage.
I have the factory alloy rims.
I decided to go with 285/75/16 Duratracs.
And everybody told me that they would rub or peel off and it could not be done on a stock truck blah blah blah.
Those things lasted forever. I only got rid of them because they are loud as hell when they wear.
So i went with 265/75/16 BFG all terain KOs
And the local tire busters told me that they would rub and it couldnt be done on a stock height truck.
Obviously ********.
Back in the last century I had an 83 K5 Blazer.
This was an old Salt River Project utility truck and just as plain zero option truck they ever made.
It came with roller skate rims and donut tires.
I had to put this thing in 4 high one day on the strip in Vegas because it had rained and I stopped on a freshly painted crosswalk stripe.
So I did some research and decided to go with BFG 11.5 X 32 all terraines on 10 inch rims.
Same story. "You cant put that on a bone stock K5.
5 years later when I went to replace them.
"You cant put 32x11.5 BFGs on a stock Blazer It cant be done they will rub and peel off the rim and everybody will die!
But they have been on the truck for years and aint nobody dead.
But it cant be done!

I went with that combo because I could leave work in Phoenix on a Friday night and bomb to the Mexico border at 70 mph and make it into Mexico before the border closed at midnight.
2 hours or so later Im on the beach in Rocky Point and could air them down to about 15 psi and still have straight and solid sidewalls.
Drive like a loon on the beach jump sand dunes for a week no problem at all.
When its time to go, air em back up and hit the highway at 70 mph all the way back.
Almost every weekend for years.
They didnt get chewed up from that, they got chewd up from rock crawling right in town.
Ripped the tread blocks off.
So I go to buy new tires.
Years later.
"You cant put 32x11.5 BFGs on a stock K5 Blazer!
It cant be done!
Yer gonna die!
But I am driving a bone stock K5 with 32x11.5 BFGs on tens. Its right here in front of you. You are leaning on the hood while telling me that it cant be done!
Chuckleheads who get all jumped up because the lawyers wrote the software.
This is one of the reasons why I only buy tires and only get alignments done at an actual 4x4 specialists shop.
It is more expensive for sure.
But about 200 bucks more.
Well worth it.
And the big difference is that the in and out quick tire shop employs kids and they drive them into the dirt.
If you are slapping a set of Chinese Happy Factory #2 special road gobblers on a Prious.
It probably wont get noticed.
If you are putting big heavy offroad tires onto a rim.
They likely wont balance at the first attempt.
If that balance is way out of parameters.
The proper way to do it is to unseat the bead, rotate the tire and try again.
Especially if it is a large tire on an alloy rim.
A production shop wont do that.
They will just chuck a whole bunch of weight on the rims and call it good.
If they are really inept. They will hammer clamp weights onto the inner alloy rims instead of using tape weights and those clamp weiths will hit the tie rod end and mill your brand new rims down to a sliver.
I did not nor would I ever take my truck to Sears.
My 2 back ex wife took it in for my birthday.
And put it on my credit card.
I bought my own birthday present and fought with Sears for a year to get them to pay for it.
And I run the BFG Kos at 45 psi for normal driving.
Seems to be a pretty good balance for daily use.

I just got those same Wranglers put on mine around 16 months ago, I keep them at 35-40 PSI ... Haven't needed to fill any of them up since I got them, which has been nice.
