appropriate speed rating and size for Falken 512?
Is the speed rating for this tire Z or W? What size does it read on the sidewall? I am ordering mine from Sears and the representative said it will be a W speed rating instead of Z. The size I'm ordering will be 235/45R17.

If you want a Z rating, go with the ST115. Lots of positive comments on this forum about it. Very quiet tire. Special order from Sears, $113. Or $93 plus shipping from Discountiredirect.com

This information below is from Tire Rack and might help explain how the W and Z ratings are applied. As you can see, a W rated tire is good for speeds up to 168, while a Z rated tire is rated for speeds over 149, which naturally raises the question of how much over 149 mph. So a W rated tire could be higher rated or lower rated than a Z rated tire but there is no way of knowing, but we do know the W tire's speed capabilities.
W 168 mph 270 km/h Exotic Sports Cars
Y 186 mph 300 km/h Exotic Sports Cars
While a Z-speed rating still often appears in the tire size designation of these tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire's 168 mph, 270 km/h maximum speed.
225/50ZR16 in excess of 149 mph, 240 km/h
205/45ZR17 88W 168 mph, 270 km/h
285/35ZR19 99Y 186 mph, 300 km/h
Y 186 mph 300 km/h Exotic Sports Cars
