Mich tire temp.

[diesel748]

I'm making the switch from Pirelli to Mich. I have Chicken Hawk warmers. My question is how long schould I cook 'em before I go out? I understand they do take a little longer to heat up than the supercorsas.

[TZDeSioux]

Minimum 3 hours!

I'll just plug em in now then wire up to the alternator on my truck for the drive up thurs. either way dog I get em up to temp!!

This is what I was told by the Michelin man (the one that does the AMA stuff, forgot his name.)

Before going out the first time: 2 hours

and then immediately after you come off the track, and leave them on all day.  It will not cook the tires.  Leave them on until you are done for the day.

I did this at Jennings in November, it didn't have a problem what so ever.  Worked well actually.

According to the Michelin man, leave them on all day, unless your on track.  Otherwise they stay on.

As above...

Thanks
Well I now know its not a quick nuke like the pirelli its a slow roast.

45 minutes minimum.. 2 hours prior?? maybe in 50deg weather.. like said above, leave on all day. Want to check which thermostats you have in your hawks too. You want the "hot" ones...

I only got the warmers on brand-spankin' new S2s at Topeka about 30 mins ahead of time and had no problems.  I wouldn't go much less than that though.

That's what the guy told me.  ??? Big guy from France I think. He was at the Jennings Sport Bike Track Time track day (the one with Colin Edwards).  Here's what's on the WERA forum:

wanted to provide all riders who use tirewarmers what the correct temperatures are according to the engineers from the top 3 tire companies. It is a question I get constantly and I thought you guys would like the info.

Dunlop

160 degrees F both font and back for 45-60 mins. (This has changed for '04 it USED to be just like Michelin)


Perilli

140 degrees F both front and back for 30 mins.


Michelin

179 degrees F back and 149 degrees F front for 60 mins.


If you have any questions feel free to give me a call.

At the AMA round at VIR I talked to Jim Rhodes, the AMA Michelin guy.  If we're talking DOT's, his recommendation when using digital tire warmers was 180 for the rear and 140 for the front.  I usually do about an hour.  You want the tire to be warm, the air inside, and if you do that, the rim will also be warm...and that will keep everything in good shape as you go to the grid.  If you just leave them on for a short period of time, you'll warm the tread of the tire and you might loose a lot of that heat.

Immediately after I come in, I put the warmers on.  If there's going to be a long time between races, lunch, etc., I'll usually pull down the temp, but I will leave them on for hours at a time.

Thanks Everybody who replied!!
This info will be very benificial.
I will see all of you @ RA look for the blue ducati 748 with the warmers on the whole weekend.

Thanks again

You haven't asked the most important question...

Will the change in tires affect my chassis?
