Heard a rumor that Hoosier won the tire bid for IMCA in 2006. It is going to be the "A "tire for mods and stockcars. Anyone else heard this? Could it be true? IMCA said in their paper that tires were up for bid.

I hope for your sake it isn't true! The A-mods are terrible! They will glaze over on the first or second caution. Most in UMP won't run them, because they are so inconsistant. We would LOVE to be able to run them, and have tried grinding and siping them to try to make them work. I know guys who soak them for days on a rotisserie, and they still glaze up. Hoosiers are 2 things on a tire by tire basis, great or terrible. Most in central IL will only run 4 D-mods or 3 D's and 1 H (RR feature). Good luck! P.S., I will always run a good seasoned D before ever thinking of running an A. Does someone here know any A-mod tricks?

I hope and pray this not true. The Hoosier UMP tire is garbage, they are horrible to mount and the sidewall is way to thin. I have had to use 60 psi to get them to pop on the bead, yes I have tried every lubricant on the planet and it only helped some. Then after getting them to pop on the bead and let the air out to get the air psi right for the race the tire comes back off the bead.

This tire is horrid. This would be a completely horrible choice for a Tire, I pray that IMCA goes with something else.

Also I dont what IMCA will do concerning the price because currently the A-40 costs more than the McCReary IMCA tire.

We use the A's and don't have the problems your speaking of. Takes us about 15-20 mins to dismount and remount one. With about 35lbs to get the bead to pop on. We have to run them so thats all i've ever ran.

Gosh i hope not, hoosier is a terrible tire, id rather pay $120 for an American racer, we also ran some hoosiers and it took 50 lbs of air to get then to mount,took us about 20 minutes to unmount and remount a hoosier, we can do an american racer in 5 minutes. Flood IMCAs mail boxes with anti hoosier emails!

I agree with Harris, these tires are horrible to mount and depending on the wheel you put them on you may not get them popped on the bead to stay, we have let the air out to set race pressure only to have them come of the bead. When have to run tubes in the non driving wheels and have had to put fix a flat in the new ones to make it thru for the night.
I want nothing to do with Hoosier.

I've never run a hoosier but it appears the overwhelmingly that the guys who do hvae to run 'em, hate 'em.

I ran at a track several times last year where you had the choice of any tire...and us guys on the G-60 generally walked away from the guys on Hoosiers. May be an isolated thing but if the Hoosier tires are supposed to make a huge difference for grip, we never saw it. In fact the hoosier tires would come back in and be torn up, our G-60's showed some feathering but the surface was intact.

Over on another site they are discussing this same topic and the guys over there aren't too impressed with the hoosier either.

The D-40 is soft and will out bite the IMCA tire in a big way, but you have to buy quite a few to make it thru, the dry track eats them.
The H-40 is good but it takes a few laps to come in cause its hard. The A-40 is softer than the H but it will glaze over during a caution.
Either way I want nothing to do with the Hoosier. When mounting there new tires its hit or miss. When you call them let them know whats going on when you mount them, they blame the wheel companies. I know this is false, because we have experienced mounting problems with Hoosiers, with several bransd wheels, Aero,Bart, Real, and Basset. After we tried each we settled with the problem being the tire.
In fact one of the Bart wheels I had would take 65 psi to seat the Hoosier tire on the bead, then as mentioned before if you let the air out to race pressure it would come off. I then tried mounting a IMCA tire to the same Bart wheel, and you guessed it the tire went right on and would not pop off the bead when race pressure was set.
Hoosier can blame the wheel folks if they want, but I know better. Also there is always telling racers to put Dawn soap in tires so they wont leak thru the sidewall as much, thats fine but we should not be putting up with this much grief, for a brand new tire priced at $115 each.

Just read on racefan, that IMCA has NOT chosen the new tire supplier yet.

Im trying to figure how these tires are hard to mount. We have mounted approximately 30 tires this spring for the 3 cars that run together. Mostly Aero and Bassett rims, but never had a mounting problem. The A's do glaze over, BUT most IMCA guys try to use them like a G60 which loves heat. I know guys that run 3400 street stocks on A's and dont glaze them over. The H is a nice alternative, but if there are alot of cautions, the H wont stay hot. The H seems to work well on a rubbered track also.

Another option that has showed up around here are the 8" Goodyears. I think this would be the best option for IMCA. They have similiar traction properties to the A40 but dont glaze over and are a little more durable like the G60's. At first a lot of guys around here were skeptical until they ran the a few times. They last longer than the hoosiers too.

Just my 2cents

I am glad you had good luck mounting the A-40. I know we had trouble mounting them for quite sometime. I have used all different wheel brands, the Aero's have been a little better but not much over all. I believe that the mounting concern has everything to do with the paper thin sidewalls of the tire. As I mentioned before we had a new out of the box bart wheel and it would not seat without 65psi. Then when we let it down to 15 psi to race on it, it popped off the bead. We later mounted an IMCA tire on that same Bart wheel and had no problems, with it coming off the bead.

At the track last year the guy parked next to us was working on his car and we heard a popping noise and the sidewall on his had let go just sitting there. A lot of the racers down here are runnning tubes on the non drive wheels, which seems to help, but also adds more weight

We have to run hoosiers, and do sometimes have problems mounting and dismounting them. I have never though not had one bead up. Usually takes about 25-30lbs to do it. Then bring it down to 8-12 lbs and have never had one come off the bead.

I do however see sidewall leaks once in a while, like pinholes in the sidewall. Not enough to lose much air though, nothing to be concerned about in race conditions.

One thing I do know for sure, and this is something I think should be more of a concern to IMCA guys. The hoosier takes away a lot of the set up advantages. What I mean is the Hoosier is much more forgiving if you miss the set up a bit. The AR tires demand chassis knowledge and proper execution to track changes...Hoosier..not so much.

I would agree with Rook, i've never run IMCA tires, but i do know that around here in the Mods were all up against a wall and its hard to pass cause it seems everyone is the same speed, handling well or not.

Most nights you pass maybe 4 or 5 cars, and sometimes it may take 5 laps to pass one car. Were just so evenly matched, usually your just waiting for the other guy to make a mistake.

I wish it was like LM's around here, alot of passing, some hit the set up alot didnt and you can see it on the track.

Never thought about it being the tires, but that makes alot of sense. Hoosier should really take a look at their product, and its impact on the biggest class in dirt racing.

As for other issues, none here but there all i ever worked with (Hoosier tires).

We have the pinholes in the sidewall too with the hoosiers. The G60 aerican racers dont leak, but the 84-8's and the 82-8 american racers which are similiar to the hoosiers used to leak too. The were softer like the hoosiers but had a stronger sidewall also.

We don't have to go over 40psi to mount our Hoosiers (we run Aero), and I will run 6psi on left side regurally with NO problems(feature time). Check out Carroll Smith's awsome book "Tuning to Win", he says (back in the late '70's) that racing tires are nothing like street tires and all racing tire sidewalls will leak a little. Indy, Nascar, ect., they all do. If the sidewall was thick enough not to leak like a street tire, you would find yourself pulling beads off and /or skating up the track. They have to be flexible for a reason. With the heat pressure build up while racing, what little leakage you might have does not matter one bit. Plus on nights that it cools off (like now), your cold pressure will drop. It is not from leaking, it is from tempurature. You cannot set your pressure at the shop and think it will stay the same all night at the track.

the thing with the softer sidewalls is you will either have to use a lot of air or you need to get the tire centered before you hit the juice. I also are any of you guys that cann't run beadlocks looked into Diamond wheels they have an extreme bead on the inside harder to mount but you can run the air down and not have to worry about it.

I am more interested in hearing the "A" verses "H" debate. A lot of the UMP Mods around here use "A"'s, but I have wondered why the "H" is not as popular. the "A" does glaze after the first caution following a long green. It was a scary feeling after my first exerience' never had the front right so close to the wall!!!

I run the "H" tire over the "A" tire just based on that reason alone. I have never had an "A" come back after a green-yellow-green scenario. "H" will keep some heat longer as it takes more heat to make them work, and it will come back when you heat it back up. Grind them in between races...

I have found that soaking the "A" tire with brake clean makes them softer, but only works for one heat cycle before you need to do it again.
