The information for Maxxis and Firestone tires is combined, since the instructions for prepping these two brands are
nearly identical; and, they are normally run on similar track conditions. All throughout the Southeast and many other areas,
these are considered the “Universal” tires. They can be prepped to work well on anything from wet tracks, to the
hardest, fastest, money-race events. But, they are also the most technically involved tires to prep. Please note,
this means these tires have the least margin of error for imperfection in your prep procedure. You may have noticed that this
section is different than the sections for Burris and Vega tires. That’s because, with these tires – more than
any other brands – it is extremely important to have a true tire program; not just a collection of tires. You need to
have a selection of tires ranging very lightly treated to heavily treated, for various conditions.
Internal
Prepping – Internal prepping
is very important with these tires – not only the fact that you are prepping internally, but the amount of prep you
use will drastically effect tire performance. Venom Juice Original is the product we recommend for internally prepping
these tires. Depending on how much is rolled, you will directly affect the bite
potential of the tire.
Factors
to consider when prepping tires from the inside include the available horsepower, weight class, track conditions. Lower horsepower classes will often require less internal prep. High
weight classes will also require less internal prep. The reverse is true as well. A very high horsepower class such as Unlimited All Star will require you have a stronger
base of internal prep. In general, our suggestions will aim for a middle of the
road baseline. If you feel your class is somehow different from the average conditions
in weight or horsepower, you should adjust the amount of internal prep that you use up and down gradually to find the “sweet
spot,” for your application.
It
is important to carry tires to the track with various amounts of internal prep rolled inside them. This comes in handy if the track conditions are not exactly as you expect them to be. You can easily adjust the overall bite in your kart by simply switching to a set of tires with more of
less prep rolled from the inside. This eliminates some of the guess worked involved
with using the durometer, and eliminates the need for excessive external prep work during the week.
In
general, for every ounce of internal prep inside of a right side tire, your tire will soften 1.5 durometer points. Therefore, two ounces of prep should produce roughly a three point durometer drop, once the tire has been
run. A tire with six ounces rolled inside will drop nearly 10 points once it
has been run.
The below suggestions are just guidelines,
and are not set in stone. They are designed to get you started in the right direction. Remember; always carry various options to the track so you will be prepared for changing
track conditions. Normally it is recommended to carry tires one step harder,
and one step softer than what you think you will need. You always need to carry
a good set of soft tires with you as well, just in case of a sudden rainstorm, etc.
· Hard, Fast Tracks (Hot Weather) – When the temperatures are warm and track bite is high, you will need to carry
tires that are prepped very lightly. Normally you want to carry one set of tires
with no inside prep work done, and another set with two ounces in the right side tires, one ounce in the left front, and no
prep in the left rear.
· Hard, Fast Tracks (Cool Weather) – The recommended amounts of prep for these conditions would be similar to those
above. You could use up to one ounce extra all the way around for slightly more bite, and to get the kart to come-in quicker.
If your tire selection is limited, you could run tires prepared for the conditions described above, or for the conditions
described directly below, depending on the individual track and available bite.
· Average Bite Tracks – Tracks like this are what most racers experience for the majority of their races. For these conditions you
would carry one set of tires prepped with two ounces in the right sides, and one ounce in the left side tires. A second set should contain four ounces in the right side tires, and two ounces in the left side tires. This will give you good options for daytime and nighttime.
· Tracks with Less Than Average Bite – Tracks that never pick up much bite require tires with slightly more inside prep.
A set with four ounces in the right side tires and two ounces in the left side tires would be your baseline set. You would also want to carry a set with six ounces in the right side tires, and three ounces in the left
side tires. These tires would be effective if the track is glazed over, or if
it is really dusty.
·
Wet, Slick Tracks – This condition exists mostly with red-clay
tracks that stay wet. This is often caused by humidity keeping the surface wet throughout the night, never letting it get
bite. A set of Maxxis with six ounces in the right side tires and three ounces
in the left side tires would work well. If it is an open tire rule situation,
you might consider switching to soaked Vega tires at this point.
· As you can see, the amount of prep varies by conditions. A great tire
program would consist of sets with no right side prep, two ounce rights side, four ounce right sides, and six ounce right
sides. The left side to match would have about half as much prep as the right
sides. Sometime the left rear will have even less than half as much as the right
sides.
Pre-Treatment
Procedure – With the introduction
of Venom Bite Pink, the pre-treatment procedure has been drastically simplified.
Instead of having to choose which prep to use during the week, you simply use Venom Bite Pink for most conditions.
Pre-treating
should be done during the week prior to race day. We suggest having the external
pre-treatment done at least 48 hours prior to using your tires.
After
you have rolled the tires internally as described above, it’s time to roll them on the outside with Venom Bite Pink. As a base treatment, we will roll all the sets for 20 minutes a piece, just for conditioning. This is rolled at air temp, somewhere between 70 and 90 degrees. In cold weather you might put the prep in a hotbox at a low temperature.
If
you are looking to soften your tires, you can roll in Venom Bite Pink for up to an hour at a time. If more softening is desired, repeat this again. Venom
Bite Pink should only be used for softening a Maxxis or Firestone to around 50 to 52 on the durometer. If you need to go softer, use Venom Soak II.
If
you don’t have a tire roller, you can substitute the 20 minutes of rolling time by wiping three coats per day, for two
days.
If
you do need to soften your tires below 50, a roller is very useful. Put the Venom
Soak II in the prep pan and roll your tires for an hour at a time until they reach the desired durometer reading. Let them cure a minimum of 48 hours before racing if possible. Heat up to 120 degrees can help this process go quicker.
Again,
if you don’t have a roller, you can wipe coats until the desired durometer reading is reached.
At
Track Prepping – Prepping at
the track is best done with a cloth rag, using light coats of prep. Unless otherwise
noted, this is the way we intend all Venom Juice products to be externally applied.
Prepping with paper towels is not recommended. Having tires warm to the touch makes prep absorb into the tire quicker,
and tires normally run best when they’re already warm to the touch when you go to the grid. Typically, they do not run
as well when they are hot to the touch. The heat produced from good sunlight is ideal. In cooler weather, a hotbox or tire
warmers work nicely. Make sure all prep has dried into the tire before going onto the track. Below is a list of track conditions,
and the preps we recommend for those conditions, when running these tires.
· Wet Tracks: Wet tracks typically require an aggressive prep. A tire pre-treated with Venom Soak II would be ideal. Venom
Soak II is also the best for these situations at the track. Wipe it on with a rag for surface bite. For tracks that have
a lot of surface moisture, tires should be wet at the grid. If you need to further soften the tires, apply multiple coats
to a warm tire. If this prep is over softening, or seems to be locking down the kart, switch to using Venom Bite Blue.
· Damp Tracks: Damp tracks can often fit in the same category as wet tracks, but the moisture is normally not as concentrated at
surface of the track. These tracks conditions can borderline on tires treated with Venom Soak II or Venom Bite Pink. If you need a lot of bite at the track, wipe or roll Venom Soak II onto the
tires. If the track dries slightly, or bite starts picking up, use Venom Bite
Blue as your surface prep.
·
Dry Slick Tracks: Dry slick track are unique. They are packed down, but the surface produces minimal bite.
If rubber is laying down, it is often very shiny and slick on the surface. Abrassion
is minimum. Normaly Venom Bite Black cut 50/50 with Acrysol will
work on these tracks in warm weather where sunlight is present. If the weather
is not as nice, or if you are racing at night, wiping coats of Venom Bite Blue cut 50/50 with Acrysol will work
well. Occasionaly, if the track is not biting at all, a single heavy coat of
Venom Soak II will help fire the tires off.
·
Dusty Tracks: Venom Bite Black is our best
prep for dusty tracks. It should be used straight, and applied to a warm tire. Up to three coats between each round can be applied.
Make sure that any slick film left by the Venom Bite Black has soaked into the tire before taking the kart to
the grid.
·
Hard Biting Tracks: When racing on hard tracks with bite, Venom Bite Black cut 50/50 with Acrysol
is the ideal prep. Usually, one to two light coats heated into the tire will
be ideal. If the track falls off towards evening time, you might need to switch
to Venom Bite Blue cut 50/50 with Acrysol.
·
Cold Weather: Treat your tires for the track condition described on the previous page, that best matches
your situation. If the weather is cooler than normal (usually below 55 degrees), you need to prep as described, plus
use an additional coat of Venom Bite Green. Make sure that all prep has adequately soaked into the tire. Allow extra
time, as prep takes longer to absorb into cold tires.
Retreating
Tires – After running tires,
or even after taking them to the track without running them, they will require work before your next outing. If you have run
the tires, follow the same directions as for pre-treating, except use about half as much prep. Pay attention to durometer
readings, to avoid over-prepping your tires. If you haven’t run the tires, simply hit them with one or two coats of
Venom Bite Pink, just to freshen the surface.
