Federal 595 RS-PRO 225/40ZR18

225 is the tread width in millimeters, 40 means the sidewall is 40% of that width, and R18 is the 18-inch rim it mounts on. 92 is the load index (1,389 lbs per tire), and Y is the speed rating (up to 186 mph).

The 595 RS-PRO is built for sports cars, performance coupes, and hatchbacks where aggressive handling and grip are priorities. It is available in 12 sizes spanning 15-inch to 19-inch rim diameters, covering a wide range of performance fitments.

No. The 595 RS-PRO uses a performance compound designed for warmer temperatures. When ambient temperatures drop consistently below approximately 45°F, the compound stiffens and grip is significantly reduced. For cold-weather or winter driving, a dedicated all-season or winter tire is the appropriate choice.

Yes, the 595 RS-PRO has a directional tread pattern, meaning the tire must always roll in one designated direction. As a result, rotations are limited to front-to-rear or rear-to-front on the same side of the vehicle — side-to-side swaps are not permitted without dismounting and remounting.

The directional V-shaped grooves are designed to evacuate water from the contact patch efficiently, lowering the risk of hydroplaning in wet conditions. That said, this is a warm-weather performance tire, not an all-season design, so it performs best in dry and mildly wet warm-temperature environments rather than cold rain or standing water in low temperatures.

Federal 595 RS-PRO tires are produced in either Taiwan or China depending on the specific production run. Federal Corporation, the brand's parent company, has manufactured tires in Taiwan since its founding in 1954 and has built its reputation on UHP and motorsport-oriented products.
