Here's the correct link - the previous one didn't seem to work properly.<br> <br> http://www.tirerack.com/tires/tiretech/general/speed.htm<br> <br> One question I have - given two equivalent tires in terms of model and size, do you sacrifice anything in terms of comfort or tire life for a higher speed rating?<br> <br> I had a choice between ZR and YR tires and took the YR, for the higher speed rating, for those regular days when I'm doing 186mph <br> <br> Any ideas?

i'm not an expert, but I belive you do,because your sidewall gets stiffer. Your snow traction also goes bye bye..

I think that it really depends on the specific tire and manufacturer. A higher speed rating means that the tire can generate more heat and take it. Construction will most likely be different (better). Tread compound might be different. Tread pattern might be different. I don't know if the 'in general' question is a valid one that can be answered....
