Whats some good ways to soften tires and get 10 to 20 points less durometer reading?

this is very unethical, but soak the entire tire in tire bite or something like that, we had a guy at our track doing that with imca tires and it really helped. he had a rotiserie set up to rotate the tire all week. we finally had to go to hoosiers to give everyone an equal playing field again.

I've heard that some guys soak them in diesel fuel & some brush paint thinners on them. Not sure how good it works though.

Diesel fuel works good, but put it inside the tire, so when brake heating occcures it will push it through the tire soaking from the inside out.What ever you use this is a good method. About 2 oz. is all you need and do this for a couple of weeks, put it in before you go to the track though!

A couple of years ago at Dennison they checked everyone's tires. They measured the hardness and if it was not within what the track considered reasonable limits, then you were disqualified. The more people cheat than the more checking and hassles for everyone.

im a tech inspector at my local track and we durometer dwarf car tires every night. we set a limit on 50 on the durometer is the softest they can go. if you use a chemical inside the tire it wont be effective till you are about 25 to 30 laps into the race. the tire by this time will have enough heat in it that the porosity level in the tire will rise and the chemical will come through the tire up to the surface. just set them in the sun light when its hot outside it will make them soft until you can get enough heat in the tire to soften it up.

What are some of the mixing ratios? and heard that wraping the tire with plastic wrap helps also!

We had a front runner who was unbeatable out our way who always had tires that were a unique charcoal black. He never had a spec of dirt on any tire,including the ones on the tire rack. I doubt they scrubbed each tire with a toothbrush each week.
Low dollar guys can use XYLENE from the local hardware store. Its an old Duke Southard tip. I think he also suggested using diesel to cut it.
Personnally ,I think grinding or scuffing is very beneficial ,LEGAL and less time consuming.
I know its hard to do at $92 a tire,but it sure helps!

We have done the scuffing bit also, We just use an angle buffer, and put a rough grit sand paper on it like 40, or 60grit and run it over the tire. Yes it does take some time to do all of the tires that you need to do, but I do think that it is worth it. Also, I dont think that it changes the reading on the durometers either. We started doing it when we ran the Legends Cars where the tires HAD to be a certain hardness and we never had any problems.

Heres your game plan. Take an old bent axle and cut it in half. Weld one half without any thing on it but splines to the stud side of the other half. You know have a "rotisserie". Go to the Walmart or Dollar store and buy a shallow but wide and long plastic tray, these usually have a lid on them and are about 5" deep, 20" wide, and 30" long. Put equelparts deisel and cheap mineral spirits paint thinner in it about 2" deep. Mount your tire on the axlething a ma bob and position it over the solution using jackstands to adjust height. You will want it to sit about half an inch into it. Spin it every 30 minutes or so for about 2 or 3 hours. Do this in sunlight if possible. This will make a difference.

We sell a product called MaxTraxion that will make a tire grip a TON better on either dirt OR pavement. It also does NOT soften the rubber (which shortens the tire's lifespan). So therefore, it does not show up on the durometer.

We also have (someplace around here) a list of home "recipes" that ARE tire softeners and actually DO soften the rubber significantly. Not recommended for the faint of heart, tho! LOL!

Anyone interested, just contact us.
