steer tire vs. regular tire ??

What's the difference in a steer tire and a regular tire?

Found a good deal on two Firestone 11R 22.5 Steer Tires, But I don't know the difference?

A steer tire , has been designed and tested by the manufacturer for use on the steering axle ; different sidewall loading involved in the tires use.
To my knowledge a steer tire can be used on a drive axle, but tires designated as drive or load axle , should not be used on the steer axle.
Most tires for RV use will be designated , multi or all axle, but with the 11R tires, used on transport trucks , the non-steer tires will be cheaper, and the cost savings on an 18 wheeler are significant.

I just learned something new.

I was familiar with the term "steer tire" but though it only referenced the position of the tire and not actual manufacturing and design differences.

Steer tires need strong sidewalks, they flex a lot more on turns etc. plus extra load, Old truckers say, if you have a blowout, your blessed if it's on the rear, not in your steer!

I had always heard that it was against the law to have recapped tires on the steer tires. But I just Goggled it and apparently unless it is for a passenger bus, recaps are perfectly legal on the steer tires. I learned something new by your posting this thread. (not that I would ever use recaps)

Been on the tire manufacturers web sites, most times if you select RV tires, you get " Multi position " tires, the Steer / Drive designations are under the highway truck sections in the tire selector.
I have requested from , Michelin any technical information available, on the designation.
Hopefully it will come in form of a pdf and I'll post it.

X2 on that.
My "RV" does have steer tires on the front, and all position tires on the back. The tire salesman told me the rear tires I bought were mainly used as trailer tires see "ROADMASTER RM120" here Cooper Roadmaster Tires - Long Haul

E mail back from the web site was not helpful, told to call the regional rep, for further info.
No Michelin dealer local, I'll see if the Goodyear dealer here can shed some light on the subject.

I believe the term "Steer Tire" was coined by the DOT. They use it to determine not only the position of the tire, but designate what type tires are allowed to be used on the steering axle of commercial vehicles. I know recapped, regrooved, and traction tires (snow tires) are not allowed on the steering axle any commercial vehicle involved in interstate commerce.

In recent years there has been a considerable amount of research trying to improve the compounds, tread patterns and optimize tread depth to extend the lifetime of tires used on the steering axles. I'm not sure if anyone makes a tire designated soley for the steering axle.

Goodyear dealer, was kind of on the same page as ; Hikerdogs ; reference to a DOT designation , and being mostly based on tread pattern rather than actual construction, but; had no paperwork on the subject .
I'll be in a larger center in a couple of weeks , pricing tires , so I'll be looking to find something in print as well.

Hate to pull a set of tires with 70% tread, and no sidewall cracking. But at 9+ years the clock has run out.
Maybe I can flog them off on E Bay.
