PRE-Z06

Mine seem to have gotten quieter as they're wearing or maybe I've just gotten used to the noise, mounted up another square 275/35 set on 18x10.5s for road course and keeping mag wheel set for auto cross.

mine still loud.

Bumping this up. Any longevity feedback? House bills are trumping car mods this year so I need to throw on a cheaper set than the RE-71r's I burned up last season; these may fit the bill.
For comparison I got 95 autocross runs, 17 drag passes, and 6,000 street miles out of the RE-71r's last season. I am at 2/32 or under on all 4 now.

I don't have any long term street feedback, but I can attest to them being a great budget track tire. They're loud as all hell but grip well and are balanced.

They wear down faster than any street tire I have used. So don't do it if you want a tire that'll last.

They do have a 140 treadwear. After I got a performance alignment with a lot more camber, they wore a lot faster, not surprisingly.

I just run a cheap ($350 a set) tire one set of wheels when street driving, and I keep the Federals mounted separately.

kdm123

Actually, I think the RS-RR have a 200 treadwear rating, and the older RS-R's (which I have) have a 140 rating. However, that "200" rating may be under rated to keep them legal from some racing classes.

Can you put that in terms of street mileage and/or track mileage/days?

Thanks Froggy!

RS-R's will last 3 track days if you drive on the limit. You'll need to rotate them to make them last. No idea about street miles, but you should just run a harder-compound street tire, as I mentioned in my previous post.

Using aggressive camber settings, I saw my lap times at Willow Springs decrease by .5 to 1 second, which is a lot considering how cheap it is to do an alignment. However, that of course accelerates your tire wear in street driving, especially when using a soft-compound tire, which is why I would recommend having two sets of wheels and using the Federals only for track driving.

3 days!!! Holy poop!!

Is that 3 days till corded or heat cycled out?

That is r888 range

Corded. Any tire will be corded after 3 days of track use, and will be heat cycled long before then.

Less than 10k street miles. Easy driving.



They are very soft & they don't have much in the way of large sizes. Like many of the "off" brands.

I got 5 days... think I could have gone more if my pressures were better. I will buy again if the price comes down. About $50 more now.
FYI: 4 20min sessions each day.

bags142

I disagree with that statement.. Kumho xs, nt 05, pss, and a couple others have proven to hold up to more than 3 track days @ 4 20 min sessions a day

Thanks! That is really soft!

Thanks as well! 5 days is A OK to me for a set of track tires

A little update on wear, etc.:
I've had these as street and practice autocross tires for about a year and ~2000 miles later. I'm estimating about 50 runs so far on mostly sealed asphalt as well as some local "rough" concrete (similar to the Wilmington and Lincoln grain).

I'm using the 235/40R18 and 275/35R19 on C6 Gumby wheels. Tread depth is at approximately 4.5-5/32nds in the rear and 5-5.5/32 up front. The "fingernail" durometer says they're getting a little harder, so they're likely starting to age out and the local times are starting to show this. For what they cost and how they perform, I'm certainly not disappointed at all.

There looks to be a newly released model that is a less aggressively styled tire, the 595 RS-Pro, that seems to run even wider. It's still a "200 TW" tire and looking at the specs are interesting to say the least. The tread width for the 275/35R19 RS-RR is shown to be 10.1 inches on a 9.5" wide wheel. The same size and wheel combo of the RS-Pro is shown as 10.5 inches!

Hmmmm. Thanks

I know this is a 2 year old thread, but anyone with more feedback on these?

I'm really contemplating a set given the 315 Rival prices at $1200+. I only locally race and these may be a good bang for the buck given my frequency of racing and talent level.

Looking into the 595RS-R (285/30/18) since those are the widest 18's they offer in the 200TW to fit on 18x10.5 square. I've only owned 50% used Rivals so I can't compare a new tire...

I just got a set of the RS-PROs in 275 and was fairly happy with them square on my C5. No crazy road noise, good grip level for the price, but they would fall off after 10-12 minutes, so not sure how they'll be with hotter track temps.

smitty2919

Thanks for replying. For me it's only local autocross in the 30-50sec courses. I see the Pro comes in a 275/35/18. What size wheels are you running? Where did you order them from, most common I see is Ebay out of CA.

RS-R has 285/30/18
RS-RR has 275/35/18
RS-PRO has 275/35/18

But I hear Federals run quite wide to where the printed size fits more like the next size up or two sizes up. 275 having a width of a 285 or almost 295.

67Ranger

I'm running stock Z06 rear wheels square. They were slightly wider than my 275 NT01s on a narrower wheel, but probably not more than 285 size. I imagine the RS-R is a less grippy compound since its older and 220 TW instead of 200.
I bought mine from Phil's tire out of NY because theres no sales tax compared to all the ebay shops. At a little over 600 shipped they're worth a try, but probably not as fast as the stuff that costs twice as much.
