Looking for a tire expert on tire softening, not for a car, but we race ATVs on the ice in the non studded class with Hoosier tires, like a 10 compound. Tire softening is legal and I'm not sure what the best way to soften is. I'm familiar with the tire sofeners on the market but have also heard of using bleach.
I'm kind of leaning toward trying the bleach because for ice racing I'm thinking the chemicals in the tire sofener would be slippery on ice, where bleach would not be????
Also do you actually "soak" them?? How? and how long? day, week, month??
Do you soak the whole tire off the rim or after mounted and there is air in it?
Thanks for any help.

A typical soak cycle for saturday racing is,
treat tire once each night Wed, then thurs, and finish friday. I do it with tire mounted on rim and on the car, jacked up with some type of drip pan under the tire. put your solution in some kind of bucket. get yourself a 3-4" paint roller. basically paint the tire with a nice even saturated coat of the solution.

have you ever taken tire temps after a race?

thats a waste of time, cut some blankets or whatever cloth you want to wrap your tires.

soak the material
wrap the tire
wrap with saran wrap

check them after 24 hours and if you want softer leave them wrapped longer.

I do it like Avila does, seems to work good.The wrap idea sounds interesting, might have to try that next year.

we have raced karts for th last 6 years were it is chemical warfare
I would think that the bleach would dry the tire out to much if soaked in it
some thing we have done in the past is to put the prep inside the tire and spin it like that it will soak from the inside out and make the tire soft all the way through so it wont go away as fast
but you hav to be careful with this as you can get your tires to soft.
if you will givr some more info an the tires such as natural rubber or senthetic maby i can give you some of the home brews that we have used

Bleach is what drag racers used years ago - hence the water area in front of the starting line at a drag strip is also refered to as a "bleach box". Bleach when applied to the tires - and then the burn out would more or less clean the rubber more than soften it. I've also used bleach on drilling rig brakes systems to clean the brake blocks from oil/grease/ect. We would just douse them and then "burn them in" to the point smoke would just boil out of the equipment. When they cooled down the brakes had much more grip and squeeled very loud which is what we were wanting in that application. So - from my experience - I don't think bleach would work so well for what you want. Try a rubber buffer/tire cleaner (NAPA has one). Maybe brake cleaner in the spray can? or you could buy one of the many tire conditioners on the market. Good luck.

go to www.4cycle.com and check the forums there is 1000's of prep post. like kart racer said it's unreal what kinda stuff they are using to prep tires from thinners,tranny fluid,diesel,wd-40 you name it if it's a hazardous chem kart racers have tried it.pesronally think you would benifit more from tire warmers then softeners on ice. you used to see alot of hot boxes when we ran karts indoors in the winter guys use anything from box with a torpedo heater pointed at it to heat lamps to get the temp in them and open up the poors
