MR2 Biohazard Posted November 1, 2020 Report Share Posted November 1, 2020 Does anyone have any first hand experience with these and can compare to other tires, RS4, RE71R, ect. From what I see on the internet it seems to be a good tire, but that seems to be from someone who is trying to sell the tires and I was hoping for an unbiased assessment. 2 Quote Link to comment Share on other sites More sharing options...
Fetterhund Posted November 1, 2020 Report Share Posted November 1, 2020 Saw those same posts. Seems promising, but... Real experience and lap time comparisons would be nice to have. 1 Quote Link to comment Share on other sites More sharing options...
Ian Posted November 2, 2020 Report Share Posted November 2, 2020 "Same lap times as an RE71R, but wears like an RS4" This was the claim I heard. Which sounds to me like the dictionary definition of too good to be true. Until someone, not the new US distributer/getting free tires to say it, actually says that, I'm not buying it for a second. If I brought a new tire to market, I also would claim it has the best qualities of the 2 most popular DOT street/race tires. Since the claims aren't actually quantifiable, it avoids that whole false advertising pitfall. 1 Quote Link to comment Share on other sites More sharing options...

JDChristianson Posted November 2, 2020 Report Share Posted November 2, 2020 Hoping to see some "controlled" testing from Grassroots soon. I have no idea if they are planning such a test but they have been on it with all the other new players in the game. Its pretty hard to do proper testing for most Chumpy Champ teams.

MR2 Biohazard Posted November 2, 2020 Author Report Share Posted November 2, 2020 I am also interested in the Falken RT660 to see grip and wear rate on those. They have a lot of sizes that could work for a lot of teams, but not a lot of 15" sizes. Quote Link to comment Share on other sites More sharing options...

They wear about as fast as the re71. They are not as good in the wet as the re71. 1 Quote Link to comment Share on other sites More sharing options...

scottyk Posted November 2, 2020 Report Share Posted November 2, 2020 (edited) Anything for Paul! Haha. Tires are stiff like a true race slick. PSI will need to be lowered when compared to likes of RS4, AO52, Re71. Suspension will need to be softened up as well. Grip was good and comparable to ADO8R, little slower than AO52(not much). Grip in wet was comparable to ADO8R. It will be a good tire choice for your Champcar. Buy some now!

I know you have all sorts of Sebring data.

CBraden Posted November 3, 2020 Report Share Posted November 3, 2020 Very interested in longevity and pace data vs RS4 and RE71R. Very, very interested. TIA Quote Link to comment Share on other sites More sharing options...
turbogrill Posted November 3, 2020 Report Share Posted November 3, 2020 They have a thread wear rating of 260. Curious what series/racing regulation they did that for. Quote Link to comment Share on other sites More sharing options...

Curious what series/racing regulation they did that for. There is a pretty real possibility that they ran the UTQG treadwear test, and the data supports a 260 stamp. No reason other than marketing to stamp lower than the tested value. This is similar to the Goodyear Eagle F1 Supercar 3 (220 treadwear) or Michelin Pilot Sport Cup 2 Connect 240 (240 treadwear), but those tires will be compared against the "200 treadwear" category.

I didn't even know there was a test Would be very interesting if that was true, at least it would end the tire debate and banning certain tires.

The test is done by the tire makers. There is no 3rd party verification. So a sticky tire that would actually be a 150 treadwear can be given a 200 rating by the manufacturer so the can sell tires to us racers. That's literally the whole crux of the tire issue. 2 different tire brands with 200 treadwear ratings, but one wears out in 1/2 the time. 1 Quote Link to comment Share on other sites More sharing options...
