speed rating R and S are?

R speed rating Speed rating R allows for speeds up to 106 mph (170 km/h) under optimal conditions. Like Q speed rated tires, R rated tires generally prioritize a particular function or unique performance over maximum speed capability. R speed tires are rare, but can be found on some heavy duty light truck (LT) tires, as well as studdable and studless winter tires. S speed rating An S speed rating indicates the tire has been approved for speeds up to 112 mph (180 km/h) under optimal conditions. Everyday passenger vehicle tires can be S speed rated, but S tires often prioritize specific performance or function. Many all-terrain LT tires are becoming available in an S rating as that’s the OE spec for many of these vehicles like the Ford Raptor. M & N speed ratings An M speed rating indicates the tire has been approved for speeds up to 87 mph (140 km/h) and an N is approved for speeds up to just 81 mph (130 km/h) under optimal conditions. You’ll find M and N ratings on tires for temporary use like spare tires

Quiter than Factory Highway Tread Tires on full size van.

I have a full size chevy van that had the original factory tires. Was concerned these would be louder but it was the opposite. They were much quieter and the ride was smoother. Excellent purchase decision.

Great Tires made in the USA

I really like these Cooper tires that are made in the USA. I used them on my long haul 1-ton Dodge truck, and I still use them on my 3/4-ton Ford farm truck. These last a long time, have good all-around tread grip and I don't notice a lot of highway noise.

Looks good.

I usually keep my tires for a long time so I am hope these last a while. The tread is deep and they seem to have good traction.
