Federal 595 RS-RR Review: Budget Semi-Slick Worth It?
The Federal 595 RS-RR sits in a weird, useful place in the tire market — too aggressive for daily commuting, too cheap for people to take seriously at first, and yet it keeps showing up on podiums at regional autocross events and time attack days. That reputation didn't come from marketing. It came from build threads on Evom, NASIOC, and S2Ki where budget-conscious drivers needed a semi-slick compound without the Hankook RS4 or Nankang AR-1 price overhead. The RS-RR found its audience the hard way, and it's stayed there.
Pick up the Federal 595 RS-RR 225/45R17 for $167 — one of the most accessible semi-slick options available for 17-inch sport-compact fitments.

Overview
Federal Tire is a Taiwanese manufacturer that's been producing performance rubber since the 1960s. Their 595 lineup has gone through several iterations, but the RS-RR is the one that landed with actual performance drivers — not just aesthetics buyers looking for an aggressive sidewall label. The RS-RR is classified as a semi-slick, street-legal competition tire. It carries a DOT rating, meaning it can be driven to and from the event, but its compound and tread pattern are clearly optimized for grip over longevity.
The tread design is asymmetric with large outboard contact blocks and minimal siping — the hallmark of a tire chasing dry grip over all-condition versatility. The compound is a softer-durometer blend that warms up relatively quickly compared to full slicks, which is part of why it suits autocross and HPDE environments where you may not get extended warm-up laps. Federal markets it specifically for track and sport use, and unlike some competitors in the same price range, the RS-RR has a consistent enough compound across production batches that the reputation held over multiple years of builds and reviews in the community.
It's available across a wide range of sizes — from narrow 215 widths on 17-inch diameter up through 295/30R18 for wider rear applications on staggered setups. That sizing range matters. It means the RS-RR is viable on platforms from a stripped Miata to a wider-body S13 or an E46 track build — applications covered in our GR86 / BRZ Wheel Fitment Guide and our S550 Mustang staggered fitment breakdown.

A UTQG treadwear rating of 100 puts this squarely in semi-slick territory — below the Pilot Sport 4S (300 treadwear) we covered in our Michelin PS4S editorial, but above a true R-compound track-only tire. That 100 rating means wear will happen quickly on the street, but it also means the compound is doing real work in terms of grip generation.
Pros & cons
Pros
- Price-to-grip ratio is genuinely strong. At $167 for a 225/45R17, you're getting semi-slick compound at a price point most max-performance street tires don't touch until you're well past $200 per corner.
- Wide size range. The RS-RR covers 17-inch sport-compact sizes and stretches out to 295/30R18 for wider rear fitments, making it relevant across a broad range of platforms.
- DOT-legal for street use. Drive to the event, compete, drive home — the RS-RR handles the dual-duty requirement most track-day drivers need.
- Warms up relatively quickly. The softer compound generates grip without needing the extended lap count that some dedicated R-compounds require before they come online.
- Consistent compound across production batches, which matters when you're building a set over time or sourcing replacements mid-season.
Cons
- Wet grip is compromised by design. The minimal siping and dry-optimized tread pattern that make this tire quick in the dry mean it underperforms meaningfully in the wet. Do not daily drive this through a rainy season.
- Treadwear is real. A 100 treadwear tire used at track events will show wear faster than anything in the 200-300 UTQG range. Budget for replacement cycles accordingly.
- Ride quality reflects the compound. The stiffness that enables grip translates to a noticeably firmer ride on rough pavement. Fine for a dedicated track car or a well-suspended build; less comfortable on a stock-suspension daily.
- Not the right tire for cold climates. Semi-slick compounds do not perform in near-freezing temperatures — grip drops significantly before the tire reaches operating temperature in cold conditions.
Who it's for
The RS-RR makes the most sense for drivers who have a dedicated track or event car — or a car that gets corner-swapped tires between street and event use. Autocross competitors running STR, Street class or time attack builds where homologation doesn't mandate a specific tire frequently land here. The GR86, BRZ, Miata, EVO, and STI communities have run this tire extensively; the EVO X platform in particular benefits from the wider rear sizing options the RS-RR covers.
It also suits budget-conscious HPDE drivers who want to experience genuine semi-slick feedback without committing to R-compound pricing. If your track days are seasonal and you're not looking to spend $600–800 per axle on tires, the RS-RR is a defensible choice that won't embarrass you in any run group.
If you want a tire that lives full-time on the street and still delivers strong dry grip without the wet-weather compromise, consider a higher-UTQG max performance street option. But if your priority is grip at events and price, the RS-RR is purpose-built for that use case.
For the widest rear fitment needs, the Federal 595 RS-RR 295/30R18 at $232 handles staggered rear applications on platforms running wider barrels — the kind of setup covered in our Subaru BRZ fitment guide and our Elantra N wheel fitment breakdown. The 235/45R17 variant at $161 is worth noting too — it comes in slightly cheaper than the 225 in this application and fits a range of 17×8 and 17×8.5 wheels commonly spec'd on the platforms above.

Verdict
The Federal 595 RS-RR earns its reputation not through marketing but through track results and forum build documentation. It's a semi-slick that accepts its role honestly — optimized for dry grip at events, not for everyday versatility or longevity. At $167 for the 225/45R17, the price-to-performance case is hard to argue against for anyone who runs events regularly. Just go in with clear expectations: wet-weather grip is limited, treadwear is real, and this tire belongs on a car that has a reason to use it.
If that describes your build, pick up a set of the Federal 595 RS-RR at ThreePiece.us and stop leaving grip on the table with a tire that was never designed for what you're asking it to do.
FAQ
Is the Federal 595 RS-RR street legal?
Yes. The RS-RR carries a DOT certification, meaning it's road legal in the United States. It can be driven to and from track events. That said, its wet-weather grip is significantly below a standard max-performance street tire, so daily driving in variable conditions isn't ideal.
What sizes are available at ThreePiece.us?
Current in-stock sizes include 215/45R17, 225/45R17, 235/45R17, and 295/30R18. Pricing ranges from $161 to $252 depending on size.
How long do Federal 595 RS-RR tires typically last?
With a UTQG treadwear rating of 100, these are not long-wear tires. Longevity depends heavily on use — street-only driving will stretch them further than regular track sessions. Drivers running autocross or HPDE events should treat replacement as a recurring seasonal cost and budget accordingly. Do not expect the mileage you'd get from a 300–400 UTQG street tire.
What wheel width does the 225/45R17 pair with?
The 225/45R17 is typically mounted on wheels between 7.5 and 8.5 inches wide. A 8.0-inch rim is the most common pairing for this size, offering a balanced sidewall profile. If you're building a fitment from scratch, the ThreePiece.us wheel catalog covers a range of widths and offsets suited to sport-compact platforms. Refer to our GR86/BRZ wheel fitment guide for a detailed breakdown of width and offset relationships on similar platforms.
