Discount Tire is replacing them with XPS Rib since LTX is on backorder. so that's a good thing...Better tire.
I don't know about the XPS being "better". However, it is a "different" tire than the new LTX M&S2.
The main purpose of the XPS Rib's steel is for more sidewall puncture and scuffing resistance on delivery vehicles that may rub against curbs a lot. For RV use, the steel in the XPS Rib's sidewalls probably will make for a rougher ride, and ... perhaps a more important negative ... the XPS has a rather smooth highway tread design.
"M&S" of course means "Mud & Snow", which IMHO is a better all around tread design for general RV use.
What I REALLY WISH was available as a super-rugged tire for Class C motorhome use is a quality Load Range G M&S tire in the 225/75/R16 or 215/85/R16 size and type. I'd use these with my stock rims at only Load Range E pressures, but travel much more at ease due to the extra plies in the Load Range G tires.
The steel in the side wall is for strength for supporting heavier loads and lessen tire roll. It stiffens the side wall of the tire. A very good thing in Motorhome tires!
