A new Hankook R-S3?
A new Hankook R-S3?
Just browsing TireRack's website as I often do and I searched for 255/40/17 tire and came across this... A 200TW R-S3.
http://www.tirerack.com/tires/tires....omCompare1=yes
The 140TW model is not even listed anymore in a 255/40. They do have it in the OE size listed as closeout, but it's any cheaper.
Is this Hankook just changing the TW rating to comply with regulations of certain sanctioning bodies, or did they actually make the compound harder/more durable? Maybe some of you knew about this already, but it was the first I saw it so I thought I would post it up. Personally, I'm a StarSpec guy.
Maybe we can get Neal to chime in and shed some light on this...

same tire, just re-rated.
NOTE:
During 2012, Hankook Tire changed the Uniform Tire Quality Grade (UTQG) Treadwear rating of their Ventus R-S3 Z222 Extreme Performance Summer tire.
UTQG ratings for Treadwear, Traction and Temperature are based on tests conducted by tire manufacturers and reported to the National Highway Traffic Safety Administration (NHTSA). These regulations allow tire manufacturers to under-rate their tires’ capabilities, but prohibit over-rating them. UTQG ratings are required to be branded on tire sidewalls and printed on their labels.
When the Ventus R-S3 Z222 was introduced in spring of 2009, Hankook assigned the 140 Treadwear rating to match the UTQG Treadwear rating required by existing competition rules. However subsequent Hankook wear data revealed the tire line provided equivalent wear to its predecessor (Ventus R-S2) and earned the same 200 Treadwear rating. This has also been supported by Tire Rack survey results and customer feedback that indicate Ventus R-S3 Z222 tires provide equivalent wear to other tires already featuring similar UTQG Treadwear ratings.
With some competition rules now requiring higher UTQG Treadwear ratings, Hankook decided it was time to officially change the Ventus R-S3 Z222 line’s rating to accurately reflect its capabilities.
Since 140- and 200-Treadwear rated tires are available*, both currently appear on NHTSA’s safercar.gov website for the Ventus R-S3 Z222 line.
No changes were made to tire compound or construction, so all Ventus R-S3 Z222 tire sizes continue to use the same by-size Hankook S-Code (part number). Both 140- and 200-Treadwear-rated tires are compatible with each other when put into service as singles, pairs or in combination.

Yup, this.

The R-S3 doesn't wear like other 200TW tires in the market place, though... The Hankook is extremely soft, rating it at 200TW is nothing more than skirting the rules to make their tire eligiable. My .02
For daily use, my R-S3s are wearing just like any other softer tire I have had. I'm lucky to get 15k miles out of ANY tire. The R-S3 have about 8k on them now and still have at least half the tread depth left.

we have an evo guy locally that did almost 20 autox's last year, 2 hill climbs (9 runs total) and dd'd his tires all summer, and is running them again this year. i'll have to check but i think he puts on 10k miles per year (although he does us winter tires). i bet he still has 40-50% on them. from what i've seen that is as good or better than the star spec's. i would venture to guess that if a guy just commuted on them with OE spec alignment settings you could get 20k pretty easily.

Maybe my friends just drive harder, but the R-S3's I've seen that guys track on wear quicker than the other tires in that same catergory. I've never used them myself. I still find it suspect that a company can just change the TW rating on their own without changing anything.
Hmm, one of the biggest consumer crowds of RS-3s gets a rule change for 200TW tires (Tire stock class) and all the sudden these wear less... Yeah right. Doesn't matter though, ZII's and Rivals are both faster.
That's debateable.
The R-S3s beat out those tires (and every other 140+ tire) on dry lateral and braking grip in all the tests I've seen.
They aren't always the fastest on a dry course though where things like "feel" and "response" have a signifigant impact on the driver's ability to get the maximum out of the tire. They are always right in the running though for first place.
I'm likely to try one of these newer tires next time I need tires though.
I should also mention, I am using these on a car that is way undersprung, considerably lighter then an EVO and without enough negative camber. It beats up the outer shoulders badly. I run up to 48psi in them to keep from killing the shoulders. I run them almost as high on the street. I'm probably getting a decent amount of extra tire life doing this as all the daily commuting miles happen in the center of the tire and it helps even out the shoulder wear from autox. I also have a fairly aggressive stretch of a 215 on a 8.5" rim (they were back ordered on 225-245 range at the time I bought them). The stretch and high pressure likely helps with the response. On a typical EVO fitment, they could wear and handle considerably differently.

Well considering nearly all trophy spots so far this year at tour's and pro's in ST classes have been given out to Toyo, Dunlop, and BFG (I think in that order also), thats pretty good info for me .
In my case though, I don't really care. I just run them locally for fun cause our lot is so awful. Still running hoosiers in SM for bigger events.
