I don't think it will have much effect on national autocross since you can't get a 10" wheel until you get to STU. And I don't think the tire will be any faster on a 9 than a 225...maybe a little.

As Emilio has noted, time attack stuff is where the big win will be.

The larger impact on autocross will come with the "1.5" version of the Rival-S in the 3-rib sizes. Consistently 3 tenths faster for the applications I am aware of (see GRM test for one data point).

My understanding is the the RE71R will not be iterated like the Rival has been or the Dunlop Z1/Z1*/ZII/ZII*. It will do it's full 5-6 year timeframe and be replaced.

Please get some 245's and break 1:17's at TMP

Just called BFG on the 245/40R15 Rival-S. Estimated release is mid-2017

Ehh, that's no good,...... Racing season starts in April for much of the country

LOL. You go from "Mother of God" excited to "that's no good" in less than 24 hours.

Something, something, gift horse, mouth, something.

:bang:

Lol, touché. I go through a set a tires a year, so it's either spend a track days worth of my racing budget on a second set of tires or wait a year to step up to what will probably become "the" tire to have.

Rival S isn't exactly a good "budget" tire for anything.

Excited. But, now I have to stretch out the current set of VR-1. Maybe "mid" will come early this year.

Tire Rack now has a page for the RS4, so seems legit for this year.

Hankook Ventus R-S4

$134 for 245/40

Interesting that they aren't listing it in 205/50 size, not that I would get them.

Just ordered a setof 245/40/15. Anxious to know if they are "Super" 200tws like the Rival-S or more regular 200tw like rhe RS3 V2

Subbed for the answer to this question. I really hope they wear like the rs3's.

Guess the tire rack shipment is expected mid march. Looking forward to info.

Interesting that the Tire Rack RS-4 page is redirecting to the tires by brand page now.

It's not even listed on Tirerack anymore.

Probably tired of the deluge of questions

Hankook Ventus R-S4

:likecat: I really like that price for the 245/40/15 TireRack has.. hopefully they perform well, I'm planning on getting a set of this first batch

They're on TR now, with an end-of-April release date.

BFGoodrich g-Force Rival S

Has anyone received these yet? Tire rack has a note about being available mid March but another line says they are in stock. They also show them shipping immediately if you add them to your cart.

Even just a durometer reading of these tires compared to an RS3 would help me decide. That brings up another point, does anyone here use a durometer? It's common in the circle track world but no one ever discusses it here.

Buy them and let us know :D
