Check out Kynetix Racing Solutions on Facebook. We are doing amazing things with these tires, as well as all the others as well. No prep, just making them last and faster.

Glad to See UMP..er ,,,I mean Hoosier letting us know what tires are legal at UMP eeer I mean Hoosier tracks for the rest of the season. (not a nice word)(not a nice word)(not a nice word)(not a nice word) funny UMP/Hoosier are really just one big company.

I have talked to a few track promoters in Central Illinois and if they could get a few tracks to go with them they would Jump ship from UMP.... Maybe all Drivers with the same interests should talk to your local promoter and give your 2cents on that subject. I agree UMP isn't all bad but they don't seem to be listening to the drivers and going in direction that drivers are asking

bring it on , bring the spoilers back, get a better tire and still have simular engine rules and let them role. and one tire for all tracks...now we are talking

Have to at least give Hoosier credit for stopping production of the new tire.

The problem is there are not that many guys that can afford it. Every year it gets less and less that actually can but, I say keep the A- mods for the guys that can afford it and get a set of rules for the B-Mods the same instead of different rules for different tracks. They do that in a couple of years the B-Mods will pass the A-Mods in car counts. I'm just curious then the guys that can afford it should not be complaining about the new tire right? Because after all they can afford it. Really for me it don't matter because,I have no vested interest just a fan of racing so, really I have no say. Just think it's healthy to have a good conversation about how to keep the sport on solid ground.

No, for the most part the guys are happy until the guys racing 2 classes above their knowledge and pocketbook start crying making them constantly change.

Great post!

What do all these UMP tires punch on the duro? I run USRA stuff and know what the KK-704 punches in say 70 degree weather.

Brand new tires in 2014 punched on our durometer as follows:

D40: 40-45
A40: 50-55
H40: 65-75 (Hoosier seems to be very inconsistent with the H's IMO, I have never bought two that punched the same)

The new A40S tires seem to be the issue here, and Hoosier claims they're suspending production of them so we'll see what happens. Old A40's in the interim I guess.

The KK 704 is around a 45-50. So The softness is not the issue. If the tread is that deep put it on a spin balancer and cut some tread off to keep it from tearing up so bad. You cut off some meat but in the end it will last longer because it doesn't tear itself up. Shouldn't have to do this but racers have been modifying everything from the beginning of time.

I thought this thread was started to complain about the tire wearing out and being junk after a night? Not about engines

[modracr41]

The hardness of the tire is not the only issue. The 40 series tire is knee deep in tread, which again allows more HP to be put to the ground. The KK704/G60 tires tread is about 1/2 or less of that. They wear good, and last just longer than the 40 series tires do. The big thing here is limiting the high $$, high HP engines which are killing this class.

The A tire is around a 52, The A s tire is around a 49.

I agree, this was the year because, your right so many racers and owners were pretty disgusted by UMP. Rule changes that don't amount to much and then others that just cost the racers more money and then throw in the sanction fee on top of the BS. I have heard some say it's just not worth all the BS anymore and something needs to change and sooner rather then later. The guys need to take a stance and tell the promoters they are not paying for a sanction fee unless things change. like I said it's not all bad. It just needs to be tweaked. And I would say by the owners, drivers and UMP

saw usra dudes at PRI and they are trying to move east. better tire, allowing spoilers, engine rules that would allow the current ump engines and they tech cars too. only thing i can figure is promoters are scared to switch or ump and hoosier must be paying some decent cash. this year was indeed the year to move with the spoiler and tire deal going on...can only hope that at the end of this season racers wont forget the tire disaster with the a40s etc. Down in STL they had a big discussion on bmod rules after ump was looking to change things too. bmods dudes I talk to are still not happy that they are being forced to go crate as they add more weight every year for not running one per ump rules. ump does not seem to be looking out for anyone but ump.
