Was shopping around for P7 plus tires, in 245/45/18 format. All I can find are ones with XL load. Doesn't XL (extra load) mean the side walls are stiffer? meaning a slightly rougher ride as well as a bit more noise? I'm looking for smoother ride and definitely low road noise.
How much is the XL a factor? otherwise I was going to go with Primacy MXM4 which are SL (standard load)
