What is the speed rating for 2001 Toyota Solara 205 60R16 tires?

You don't mention the brand tire you're running and by now the OEM tires have probably (should have, actually) been replaced. The good news is the information is right on the sidewall of your tire. After the size 205-60-R16 will be a letter of the alphabet M, N, P, Q R, S, T, U, H, V, W or Y. That letter is the maximum speed the tire is rated for. "M" is the lowest speed rating, good for a maximum 81 mph, "N" goes to a whopping 87, "P" to 92 and so on. The most common ratings in the U.S. are "H" rated for 130 mph and "V" rated for 149 mph. If you have super premium "W" tires you're ok to 168 and "Y" to 186. There are combination lettering schemes above that mark. Now you're headed out to 'read' your tires but one more thing. Unless you're sure all four were replaced by the same brand check them all. The speed rating of the entire vehicle will be determined by the lowest rated tire.
