What specifically didn't you like about them, besides "sucked"?
Do you mean just in the wet? Wet during competition, or they sucked in the dry during competition? Wet on the way home?

 

No, obviously these are the tires to have in the dry. I switched from the'Stones to these and have absolutely no complaints. These are definately on par if not slightly better than the Yokes.

As far as wet competition use though, the Dunlops are not that great. Where my 'Stones would grip much better in the wet the Z1s just washed out. On the way home from the event the Z1s were hydroplaning like crazy, even through the shallowest of water. I never experienced that with the "Stones, which were also shaved to 4/32nds.

 

Ah, okay. Thanks for the explanation. I guess I just have very low rain/wet expectations from a tire.

 

Maybe, but remember that Jarrod asked about the the z1 versus the hoosier wet race tire. The hoosier will evacuate lots of water and will squirm and heat up even through standing water. On a formula car you can get almost 1G with them even in terrible, terrible conditions. Now, that's a lot worse than an A6 in the dry, but much better than a z1 in the wet.

I can verify Hoosier wets will do 1g in all directions in standing water at autox speeds.

It's really unfortunate we haven't had a chance to unleash the hoosier wet fury in competition yet.

nearly 2 years and the only rain we've seen has been at a practice event (in topeka ).

 

I would assume you would run a narrower rain tire than what you run in dry? Less water to evacuate, although less "potential" overall grip? Probably depends on how much water there is . . . narrow for an inch of standing water - wide for a thin film??

 

Does the white beastie have enough power to do 1G accel??

 

it gets pretty close on the launch. no where near in second gear.

 

This is one of the best threads on EvoM

 

Adam-

How can Tire Rack rate them as the #1 rain tire and you get such a different result? I have personally found that the Z1 Star Specs performed wonderfully in the rain, even in a panic stop situation. ( I had a Nissan Maxima spin in front of me on 495 in DC). Were your suspension setting on a hard setting that may have contributed the the less-than-stellar permance? Care to splain' me somethin'?

He said he had them shaved. I would assume that is the majority of the reason they did not work so well for him . . .

 

Has anyone ever tried using a Hoosier wet in dry conditions? Any idea how many miles you'd get out of it before it wore thru or started chunking off?

Reason for the question is I'm looking for wider tires to use at PPIHC next summer. I was using Yokohama tarmac/gravel intermediates this year in a 205-60-15, and we're looking at adding 200whp to the car for next year's race, and a 205 width won't cut it anymore. Straight summer tires are too hard, and most race tires don't have enough tread depth/tread blocks to effectively grip on the dirt.

For those unfamiliar with PPIHC, you've got approximately 3 miles of tarmac, 3 miles of very smooth dirt (often blue-grooved), 3 miles of pavement, then 3 miles of dirt. If anyone has any suggestions for tires that might fit the bill if the Hoosier wets won't work, I'd love to hear it.

If you guys want to keep the thread clean of PPIHC tire discussions, please feel free to PM me instead of replying.

Thanks!

Not long. I mean they are made to squirm around and heat up in a hurry. Without water to keep them in check, say bye bye. I would just call hoosier in ask. Another option might be their dirt track tires. Do you have to run radials?

The STU thread probably isn't the best place for this discussion. The Hoosier rain has a treadwear of 40, which is way below what is legal for STU. I dunno, new thread?

I've driven some hoosier wets around on the street for 10 or so miles in the dry without any sort of problem. They aren't "super" fragile in the dry. They were the only tires I had at the time and needed to diagnose a problem. There was no adverse wear. This wasn't very aggressive driving though.

 

Dave,

After posting this I thought back a little a realized I had run my 'Stones in the wet on full tread. The Z1s were shaved to 4/32nds.

As you know, I'm running the Ohlins DFVs (same setup as Danny's) so the settings/ rates are much softer than yours, which should have aided in wet weather grip but, I was really unimpressed with the Z1s in the rain.
