I got 4 slightly used tires for my Tour. They all seem about even in wear.They are Goodyear Eagles. After I got them, I noticed that 3 of the tires say Eagle RS-A and 1 says Eagle LS.
Is there any difference in the RS-A and the LS?
I need to know because sometimes while driving I can feel the car vibrating. The car vibrates strongy while accelarting from a low speed to a high speed.
The tires are 225/50/R16 and I have stock suspension. I use to have 205/50Z/R16.
