At the Track TRACK TESTED: Federal 595RS-R

Heres all the data that I acquired over the weekend at Auto Club Speedways ROVAL configuration with the 14*degree NASCAR banking through Turns#1 and #2 running the Federal 595RS-R street tire in a 255/40/17 in all four corners. The UTQG rating of the tire is a 140AA/A... The tire temps are pretty funky most likely due to using a hand held IR reader instead of a prob.

My car is a 2006 Evo making 370hp on 91octane at 26psi. It weighs a whopping 3433lbs w/out the driver. I'm also running about 3*degrees up front and 1.8*degrees in the rear...

Surprisingly the tires held up great. I never felt the tires greasing out during an entire 25min session... I would enter T1 at 140-147mph and maintain 130-135mph through the entire banking, almost breaking the 2G barrier with the tires at that...! The durometer also showed that the tires were actually softer than what we started with when I checked at the end of the day...!

Braking with the 595RS-R's was very impressive with the ST-43 pads. Scrubbing off the 135mph T2 exit speed coming into T3 at 40mph was pretty confident inspiring.

Tire wear is surprisingly minimal. I dont have pics of the tires as of yet but will shortly...

flame on....:beer:



GREEN RUN



1st TRUE SESSION



LAP TIMES






255/40/17 Nitto NT05 (left) = 255/40/17 Federal 595RS-R (right); both unmounted




================================================== =


I'll see what I can do about the sidewall measurement... a 255/ Federal 595RS-R looks more in the range of a 265... you should be able to purchase Federals through OnlineTires.com or anyone that uses TDW (Tire Dealers Warehouse) as their distributor...

here are all of the 595RS-R sizes....




and here are some available R-comps...

Wow, thats great to here i was just looking into some federal's albeit the R-comps. But from what you have shown they are not so much needed. Thats very impressive given there price point. I think you just made my mind up.

Any photos after your track sessions to show wear? How did the sidwalls feel vs the NT05...stiff, or soft?

Ive been looking at the 195/50/15's for my Miata to go on a spare set of wheels.

Based on the specs, they are pretty damn close to the 205/50/15 RE-11s I currently have, which tend to be on the wide side anyway.

This entire post is a comparison between the Nitto NT-05 and the Federal 595RS-R

So are they faster or slower than the nt05's? It's nice data but it's not a comparison. Maybe that's not what we're going for here... What lap times do you do with the nt05's? Or any other tires with the same car setup

Thanks dude!

I don't see why you would compare these to nt05's. The tread wear on this federal tire is way lower. I'd be more interested to see how it compares to an ra-1 or an nt01

Ah, now that we see the whole stack it's not as wide as it looked in that first picture.

Thanks dude!
Its hard to say because when I was testing out the 595RS-R some portions on the track were set-up more open then when I previously ran there a couple months ago. Making the track run about 1-1.5sec faster...

To sum it up, I was within less than .5 of a sec with less power (370hp on 91oct -vs- 400hp on 100oct) and the given track config...

So I can say they are faster, but there is a gray area...

I consider ACS's ROVAL configuration my home track as well...

The tires you mentioned are R-comps and are both 100TW tires... I only compared these with the NT05 because I have used them extensively over the years and it is a competitive street tire used in the Redline Time Attack series I run in...

each tire manufacture makes up its own UTQG/treadware rating... just because the NT05 says its a 200TW tire doesnt make it the same in another manu. A tire from another manufacture with the same rating can be softer/harder...

Yah that makes it tricky. My home track just changed configurations permanently and it kinda screws up any bit of data pre 2010.

so between the two, which tire would you choose for your next track day barring price as a factor? from every thread i've read on here, the tires are great but always on backorder. i've always wanted to try these out and i had my eyes set on the nt05 for my next set of tires.

yup. you can't compare UTQG across manufacturers.

www.citytireonline.com is a federal retailer.

Here's some good and bad news for those of you that are interested in the Federal tire line up.

After you're done reading, please reply with the sizes you guys are interested in so I can relay the message.


Thanks,
-Matt



================================================== ==========

Hello Matt,

Thank you very much with this great news on a blue Monday here in Taiwan. I have brought up this issue during our morning meeting and the answer that I got is that even though we have about 15 major distributors in America, the only main buyer of 595RS-R is from TDW. However, their buying volume is very small from such a big distributor. The true reasons, which I don't really know and quite frustrated with remain a mystery to us. Perhaps by spreading out words of demand from your EVO clubs and RTA forums could make them be more aware the potential of our 595RS-R. Do you might know other info. such as your friends' inquiry on what sizes of 595RS-R they are looking for and maybe you might even know a potential distributor that I can try to promote better with our motorsports products. Our 595RS-R is really popular in Japan and other countries with drifting events. Thank you for the effort in advance. As regarding to our FZ201 and FZ202, it's true that we haven't finalized which distributor will get the right to sell these tires. Hopefully by next year, you will see them in US soil.


Cheers, Jason...
