Product info:

Moonshine “grape” inside(purple)- this is our inside prep designed for all types of tires in all types of racing. This inside prep drops the duro while adding bite in the tire. On kart tires expect a 1 point per 10cc drop. the larger the tire, the more you will need to drop the tire. We dont recommend inside prepping some brands of tires in certain situations, we will get more into this in applications.

Moonshine “bubble gum” aggressive(blue)- This is our aggressive prep in the Moonshine line. Bubble gum is a great trackside prep to fire the tire in wet, slick, or cold, low bite applications. This prep dries well and can be used mixed with other preps in our line. It will drop the duro 2-10 points depending on use.

Moonshine “cherry” medium/bite(red)- Cherry is our medium based prep that adds a ton of bite to the tire. this prep is our most used prep on race day at any track that get good but becomes dry slick or sandy. Cherry is oily and slow drying which makes it great to cut with other preps or use as a bite adder in others. 0-6 point drop depending on use.

Moonshine “watermelon” hard track(pink)- This is our hard track, non aggressive, lite prep for those situations where the track is really good and making bite. this prep is best used when you only need to get the tires fired off and going. very little to no duro drop.

Moonshine “green apple” heavy weekly(green)- This prep is best used during the week on tires that are going to be run on slick tracks or aggressively prepped tires. will drop the duro or help maintain lower duro tires for wet tracks,

Track tac AT2- This prep is one that we use during the week in all med-high bite applications. This product works well and we didn’t feel the need to make a prep when this one does the job very good and is readily available. will drop duro 0-8 points depending on weekly use.

Moonshine Car prep #2- this is our car prep made for all types of car racing tires. dirt, asphalt, oval, drag, road course, it applies to all. We use this as a base on all car tires. It adds great bite, keeps tires consistent, and is hard to detect with proper use.

Tire preparation-

When looking at preparing a set of tires there are a few different factors we look at to help us make the best decision on what needs to be done. The track, weather, time of the year, class being run, and size of the race are some of the big factors that will help you come up with the best plan on fixing a set of tires.

The track- Dirt content, moisture content, size, and shape can be looked at in fixing tires for a race. The more clay in the dirt, typically the more bite the track will have. if the track retains a bunch of moisture typically you will need softer or deeper tires depending on the brand of tire you are running. At the larger tracks roll speed will be more crucial meaning you might want to try and fix the tires to maintain that, and not over prep.
Tracks with tight corners or that are small in general will require more bite to not slide, also affecting how much prep the tire should have.

Weather- The weather will have a big part in your tire preparation of the new tires. In the cooler months of the year you will want deeper tires and more prep in the tire to hook up on the typically slicker track conditions. during the warmer months you want to lessen the amount of prep with the hotter temps and the tires being more flexible, also the tracks dry out and harden up meaning less prep is needed.

class being run- the lighter the kart (i.e. Jr. classes) typically the softer the tire will need to be in order to keep the kart from sliding. with the light kart and less power the softer tire helps the momentum up. As the karts get heavier the less prep will be needed to achieve speed since the will have more mechanical force to help create bite.

Size of the race- this is one of the factors I have used to help make decisions on tires for a few years and it typically falls in line. the bigger the event the more the tracks progress, which will change you approach to the new tire. The bigger the race and more karts present create a more run in surface typically harder and has more grip. less aggressive prep or less prep all together may be a benefit.

New tire prep-

When we look at prepping a new tire we will have to determine a few things. Do we need inside prep and if so how much, do we need outside prep and if so what type and how much?

Most tires we run these days will benefit from inside prep with the exception of some soft compounds of Burris, els(some do some don’t), and hoosier. For the general purpose of this section lets look at the Pink and blue maxxis tires. We will pretty much always inside prep these tires, the amounts we have seen good results with by using the “Grape” inside prep are between 50-150cc. for example during the summer 50-90cc tires, spring and fall 75-125cc, and 90-150 in the winter. Within each range you can use your other factors we talked about above to determine what will be the best place to start. This is an example and is not a hard “you have to be in this range” type of deal. I do feel confident you can build a very competitive program using these guidelines. On my tires i typically roll the same amount in all 4, sometimes less in the lefts when we are talking about larger amounts of prep. for other brands we typically refer to duro reading and roll to achieve the drop based on a 1 point per 10cc rolled.

Our outside prep to new tires will have a little more variation. There are times when not wiping might be your best option , but we generally feel it is better to so some wiping to new tires at home. We have our “green apple” and AT-2 that we use for our wiping at the house. These preps can be used separately or mixed to achieve the desired effect. “Green Apple” is our heavy base prep and will drop the duro more so than the AT-2. Once again we go back to our factors to determine what the best plan of action is. Colder- more wiping, warmer- less. Better clay- less wiping and lighter prep, less clay- more wipe and heavier prep. more moisture- more wipe and heavier, less moisture- less wipe and lighter. Examples of amounts and prep can be as little as 1-2 wipes with AT-2 on a high bite, dry clay track to 10-12 wipes of Green apple on a low bite, wet, slick track and a middle ground being 5-6 wipes of a mix of Green apple/AT-2. Using these preps will get you a consistent program to put you competitive. there is always exceptions, some track may require you to wipe our Bubble gum(aggressive) during the week to get more bite in the tire but these are few and far between.

At the track-

We see a variety of track conditions every time we show up to a track. tracks generally start off wet and slick from the track prep and then get better though out the day, and may fall off as they go into the night. making the right decisions on what to wipe trackside is something that is learned over time. we can once again look at our factors to help us choose where to start, and also how to keep up.

In practice we like to scuff our new tires in to get the mold release off and run in the tires. we typically do this without wiping. this allows the tires to get run in well and it lets us know how much bite the track has during practice. if we go out in practice and are fast running in our tires, we know we just have to find what trackside prep will fire the tires off optimally. cooler, wetter, or slicker tracks we use “Bubble Gum”, intermediate tracks or tracks that get sandy we use our “Cherry” and tracks that bite up well and dry out we use our “watermelon”. we can also mix these preps to achieve the desired result and get an in-between type of prep. the track preps are three totally different chemicals and work well along or together when needed! What, when, and how much are normally the biggest and hardest questions to answer because the solution will be different for different folks. the biggest myth today is that there is one perfect answer to what tire you need and the truth is there is many solutions and combinations that can work. The best racers and tire guys in the game will all run in the same tenth and I can promise you they are all on different combinations of inside, outside chemical, number of wipes, etc. they all run so close and are so good because they work on their program and refine it to make it work for them. In the end if you do the same, using quality chemicals like the Moonshine Tire Prep line, you can achieve the same result and have great tire program. ill run threw some scenarios in the next section on maintenance and tire strategy.

Tire Strategy and Maintenance-

Now that we have talked about the different parts that make up a tire program its time to put it all together and build a program that works for you. Generally I like to use a three type tire strategy in building our program. The main reason we do this is that is seems to be pretty easy to understand and it seems to fit the widest range of racers. Some people have other strategies and they do work, this is just what we tell folks to start with if they are starting out or starting over with our chemical line. The Three tire strategy i’m speaking of is to categorize your tires and have one of each variation. A new tire, an older scuff, and a rerolled tire. With these three options you have enough to keep up with changes the track takes and to be prepared to cover many normal tracks. Additionally it fits well because most folks can justify a new set of tires, and have older tires from previous races that we can use to cover the other options. I personally define a new tire as once that has been rolled internally 2 weeks or less and has not been raced more than one feature in that time, typically only scuffed. The older scuff category can be 3 weeks to 2 months, and I will use my 2 month plus old tires for my reroll tire option.

Here’ s an example of what I do to get ready for a race. Using the factors we talked bout earlier I will make my decision on what I want to do with my new tires inside wise and then look at my older tires to find some good tires to reroll. I typically roll tires on Sunday- Tuesday to give them time to cure before the weekend. I reroll to drop the duro using the formula from above so the amounts will vary. If you have a specific situation you are unsure of feel free to message or email me and ill give you my opinion on it. I’ll wipe through out the beginning and middle of the week typically finishing my preparation by double checking stagger Thursday.

Now that we have done the work at the house when we get to the track we now have to make the right decision on what tires we will need. I typically send out the guys in practice to go run in new tires as i had said above. When it comes down to last practice we will see how our times compare on the new tires. If we are real close on times we know the new tires will most likely be a good tire to start qualifying on. If we are off we will go to the scuffs and see if they pick up. Most day races will require one of our first two options to qualify. If we qualify well on the scuffs we can go to the reroll tires if the track slows down at night. If we qualify the reroll tires then new tires will generally be good if the track falls off. If we qualify new tires and the track is getting better you will need to go to the older scuffs or reroll tires for the features. When new tires are fast in qualifying and the track falls off you will have to wipe more or go more aggressive with your at the track prep. There are hundreds of situations and combos of tire and prep that can and will work. For more in depth talk on your situation contact me and we will work to get the best program put together for you. I hope this info is helpful, it is a general guideline and should be used to gather ideas on how to improve you tire program. Let me know how i can help!
