REVIEW: Federal RS-R /40/17 tires, 10, miles later | Fiesta ST Forum
The Federal RS-R tire is an ultra high performance summer tire that gets good reviews for fast lap times and good handling characteristics on a wide range of performance vehicles. The RS-R tire tread blocks are reinforced with bridging across the tread grooves at equal intervals around the center and the shoulder of the tire. They blocks are arranged in a flame pattern that works to efficiently channel water out from under the tread. This attention to detail delivers better handling and prevents irregular wear. For an inexpensive tire, the Federal RS-R offers an impressive amount of technological advances in design, construction, pattern and compounds.
