Re: Whoa! $115.99 Michelin - 255/35X19" Pilot Sport PS2 at Costco
The only difference i see is 255/35ZR19 - 400.99 -- 255/35R19 - 115.99
*For tires having a maximum speed capability above 149 mph (240 km/h), a "ZR" may appear in the size designation. For tires having a maximum speed capability above 186 mph (300 km/h), a "ZR" must appear in the size designation. Consult tire manufacturer for maximum speed when there is no Service Description. Example: P275/40R17 93W at 168 mph (270 km/h) or P275/40ZR17 at above 149 mph (240 km/h). Consult tire manufacturer.
Would it matter if you don't get a ZR rated tire?
