I bought a set of Nitto Terra Grappler G2 265/50/20 to install on my LR4, however, my local tire shop will not install them because they are S rated and not W or Y as recommended by LR. This seems rediculous since I'm not even sure the LR4 would get up to 112 mph, much less 160 or 180. Their excuse was that if they installed the tires and I got into a wreck, they would be liable for putting tires of a different rating than recommended by LR. Anyone else had this issue? Should I try another shop, or will they likely say the same thing?
