What is the difference between "Steering tires" and regular tires?
Well, on a Semi Truck, the Steering Tires have to be "original" tires, that is not re-caps, Not sure about re-treads (but think that too is frowned on)
the driver and trailer tires can be re-caps.
And that is why Steering tires are better they do not toss their re-cap like trailer/drive axle tires can.
On most Semi's you toss a re-cap tread and you need a new tire, and if they track the re-tread to you, perhaps a new car for the guy that hit it.
But on a motor home you may well do thousands of dollars in damage to plumbing, electrical and fiberglass cause those idiots insist on running your vital systems THROUGH the wheel well where a failing tire can tear them all to shreds. (NOT something I'd approve of if I were running a RV manufacturer) inside the FRAME rails yes, inside the wheel wells NO, but guess where they ran 'em.
