Tire advice

Math says
275/80r22.5 39.79" tall
295/75r22.5 39.89" tall

With that said, I still wouldn't want to run it.
I'd assume little harm will come of it.? Depending how bad I wanted to keep moving, I might run it to the house, or down the road to a shop with a match for the Michelin..

 

I have no idea but other than a slight size difference is it ok to run two different brands on the steers?
Would they perform the same as in would or could one brand grab differently than the other which in turn could cause a bigger issue in an emergency or hard stop??

 

It'll get yoy on the road till you can replace it, or you could run it out. People do it all the time.

I'd put another Michelin on though

 

Why not plug /patch the tire with the screw or put a used steer on the truck and get to a tire shop that has what you want.
I doubt you will match your existing good steer with identical wear.

When I have a tire problem on the road, I use the cheapest option to get home.
I always change my steers in pairs, when I can get home to my local supplier.

Your situation above. If buying a new tire is the only option. I would run until I got home and change both. Everyone can use a good spare.

In my early years I would mix and match sizes and brands to keep my truck rolling. Now I have the option to do what I do.
Nothing wrong with what the TA tech said.
Good luck

 

That's fine. Sizes are the same.
Different brands. But if you have to move it gets the job done.

 

Nothing like getting a big ### ticket, and anything else that comes with smashing a huge safety rating slash.

Can't pulg a steer. Can't patch a steer.

Worst ####ing thing in the world is losing a $700 tire to a nail, right after getting reamed by a dot cop named sue.

 

Since they are steers, it's a bit different than the drives or tandem tires. Many truck stop shops simply won't plug a steer and put it back on. Right or wrong, they usually won't do it on a steer.
I'd personally be very leery about running 2 different, unmatched, tires on the steers. If that's the only option, I'd only do it until I could get a matched set. Matched set being 2 tires of the same brand, size and model and close to the same wear.

 

During hard times way back, I’ve had a front steer plug and patch. I got the life out of that particular tire without any issues. Today, if it would happened again, I would buy 2 brand new steers. But in an emergency on the road, I would probably have it patch just to get home.
Btw, you couldn’t give me an Ironman tire to run.

 

I bet we all could. I'm sure there was one accident that made news that ended a perfectly safe practice back when cars burned Ethel.
