Federal RS-RR's--anyone using them on a road course?

I've been wanting to run that track, been watching some videos and looks like fun. Short... lol But fun. I just know NASA AZ runs there so I could do a race group (with my other car, not mustang).

Great grab on those tires! Nice price ;) EDIT; found them on ebay for $585 :O

Post up your opinions when you get a chance to use them!

275/35R19 are available in these for $231 ea. They're usually about the same tread width as a 285/35. In this tire, it's a 10.1" tread width, which is quite sizeable and perfect for a 10" or 10.5" wide wheel.

9.5" is the measuring width for that size (all mfrs). 275/35's are actually OK'ed from 9" all the way out to 11" wide wheels . . .

I’m thinking about rsrr in 265/40/18. The overall diameter is 26.3inches. Would these be too short? I got my first track day coming up in April and I want to pick up some stickier tires. I have a V6 with the 3.15 gears.

You should be fine (and I suspect better off than with 27" OD tires).

I run 25.9" tall tires with 3.55's and a 5900 rpm upshift indicator with about the same power as you're making (unless you've added some sort of forced induction) and I don't quite have to upshift from the 1.00:1 gear. You've got enough more mph available for both redline and axle gearing reasons that you still might not even need 5th very often. These days, 265/40-18 is my normal street-duty size.

Just snagged a set of the 275/35/19 for $485 shipped! Ebay has a 20% off coupon right now (maximum savings $100). But still a pretty good deal

Out of stock now? I guess I got the last set :shrug:

Yeah, maybe another seller has them close to that price, the 20% off coupon is basically for anything. code: PSPRING20

SON OF A........ Nice savings. I may buy a second set just because!

Just ordered my 265/40/18 should have them within a week

Just ordered a set $145 a tire on Amazon, free shipping- getting them mounted on SVE R350 wheels- looking forward to pulling off these awful Pirellis

I ordered a set of 2753518's on eBay Not sure when they will get mounted and used at VIR

Anybody yet??? Looking to get a set of these or the FZ-201 for track use for my Focus ST.

I have moved to 18x11 wheels so no sizes for me.

Just finished up a day at the track with my 275/35-19 RS-RR's on 19x10 GT7 wheels. I'd have to say they are solid for the price. Are they comparable to an NT01 or an RC-1? Kinda. They share some of the traits of both those tires but pack the overall grip of them. They also sound like a freaking turbine. I thought I was rubbing something when I was slowing down for the carousel. They had great turn in and loved to four drift/rotate they the corners. But if rushed into a corner with too late of braking, they would squeal and push. I would compare them more to a first green RS3 or R888. I will be buying these again since I am cheap and mostly do lead files, ride alongs, instruct and Time Attack. I ran a 1.03.8 today where I ran a 1.04.7 when the car was in stock tires. Unfortunately the track had been repaved and there are some serious bumps that have been added so a direct back to back same track same car but with different tires would not be an apples to apples comparison. If you are on the fence, I don't see a purchase of these tires being a bad choice.

275/35-18 is officially OK'ed all the way out to 11" . . . do-able as long as the short diameter doesn't run you into some speed-in-gear issue requiring an extra upshift (and downshift). Don't worry about what a road course wheel & tire combination might look like to the Cars & Coffee crowd.

Where do people buy these federal rsrs?
