Thread: Foam Tires

  1. #1

    Foam Tires

    There was a huge problem at the recent IFMAR World Championships in Florida due to some people using different "traction compounds" on their foam tires. Some people did, and some didn't. One whole day (out of the three days) for qualifying was lost, as IFMAR put in a system to prevent people from doing this.

    IFMAR needs to come out with a good set of guidelines as to what is permitted. Then ROAR may need to follow. Even then, what if someone were to do this to their tires before they even came to the race track? Is this destined to become as much a part of 1/10 and 1/8 nitro racing as it is for carpet tracks for 1/12 and 1/10 scale pan cars?

    Anyone have any suggestions as to what should or should not be allowed? Now that people know about this, can we expect racers to be treating their tires before they go out on the track for local, regional, or national races?

    .........or should we just ignore it, and let racers do whatever they like?

    I can imagine if it is allowed within the ROAR rules people do not want to go without it or are just making their own choice. In Europe it is otherwise, it is forbidden by the rules but people are doing it. The EFRA thought an expensive electronic sniffer could detect the chemicals but probably the stuff can not be detected as showed on the last Europian championship for A-drivers.

    I have heard stories how it can go on large electric events where several brands of tire sauce are on the table and all are tested and even mixed to get the best results. If not, then they can always get the stuff at the track that works. That is not what you want if there is enough grip to drive without it. Some say it can make an improvement of several tenths of a seccond so within Europe most drivers who do not sauce are fooled by the ones who are doing it. Because ruling is difficult in Italy they now have stated it is alowed and there starts the conflict on Europian races as we have seen the way of thinking between the Europians and Americans on the last IFMAR WC (and the one before that).

    This issue is not healthy, it seems the guys who are not doing this could be placed higher in the ranking(s) in front of the guys who are actually cheating.

    The differences in rules are making conflicts everywhere. I can see it with electric touring where there are lots of conflicts about yes or no to the "zero degree" ESC and also about the turns of the motor. The 235mm cars were different over the world, 2wd, 4wd, touring and GTP did make a World championship difficult and the list goes on.

    If I remember correctly, many tracks in Europe don't spray their tracks with "traction compound" before the event; racers drive on the natural surface. My memory might be very fuzzy here - I just don't remember seeing some kind of "goop" sprayed on the tracks.

    In the USA it has been a part of on-road fuel racing for as long as I can remember. Way back when, a group of people would set up the boards to mark the track layout, and then someone would walk around the track, spraying the track surface with what we called "traction compound". Different tracks used different kinds of traction compound. Some used a mix based on drinking soda, some used a mix based on old r/c car fuel, and other had their own particular blends. Now we've got spraying machines that have been built by different tracks that get towed around the track, spraying it. At some tracks I've been to, you don't even notice that the track has been sprayed. I remember other tracks where the track surface was so sticky, you had to actually pull your shoe away from the track - it felt like glue!

    Roelof, as you pointed out, there apparently are no uniform rules on this. Also, some kinds of "tire dope" may be difficult or impossible to detect with any kind of "sniffer".

    As I see it, let's say using tire dope made you one second faster per lap. People using tire dope will now be faster than others. This means "others" will also need to start using tire dope. In a short time, everyone will be using tire dope - it will simply be a part of r/c on-road racing.

    What have we accomplished? Everyone is now one second faster, so we're back to the status quo. Finishing orders will be the same as before tire doping started. However, we've also increased the complexity and cost of racing. It's now one more thing everyone will have to do, and it won't give anyone a technical advantage over others.


    Many years ago, Art Carbonell went to a World Championship held somewhere in Europe - I will ask him later today when and where this race was being held. Art said that it was very rainy, and the rules at that time were that you had to race regardless of whether the track was dry or wet. The local people were used to this, and had a tire, made from unobtanium-rubber, that worked better on rainy tracks, but people visiting the track couldn't get any. It was a home field advantage. Art found out that coating his tires with a layer of silicone gave him a huge boost in traction on the wet track, at least until the silicone wore off. So, Art and his friends started doing it, and now they had an advantage over the locals. According to Art, using "stuff" on the tires to improve traction was banned, and the race rules for IFMAR World Championships were changed, with most racing only being allowed on dry tracks. (The lower finals still get raced "rain or shine"; I remember the recent W/C in Australia where racers were struggling to waterproof their cars, and most people were failing miserably. Electronics went out, and the cars had practically no traction. Then there were racers like Mark Green from England, who didn't seem to be fazed by the water at all.)

    Back to the "tire doping" question, it seems to me that if we can't find a realistic way to control it, maybe it's best to just ignore it and let people do whatever they want. Just leave it up to the local tracks to set their own rules. It's like fuel additives - it takes too much time, and is too expensive, to monitor some things. Fuel additives can be controlled at big races by using hand-out fuel. Because of all the different types of wheels in use, let alone the choice in tire hardnesses, handout tires could never be an option. Unless/until we find a way to control it, maybe we're stuck with letting people do this.

    About the rain tires..... It is crazy to believe the lower finalists of a WC need to drive in the rain trying to bump up to the higher finals while the finalists have a spare day to get a possible dry final. "one for all, all for one" so everyone have to drive in any type of weather. By the way, in the last 2 months I have driven 3 rain races without problems....

    But yes, most of our tracks do not get sprayed. Most tracks are layed down with a special asphalt sometimes with more rubber inside and the 2-stroke oil on the track from the exhausts with the rubber from the tires does create the grip. The tracks created on low grip surfaces can be sprayed with something that works.

    In that case, you could do the world a favor, and create a new thread here for Rain Racing, explaining what to do to your car to allow it to be raced in the wet. Most people in the lower finals had no idea what to do, and their improvisations usually did not work. Cars were dropping out of the race before they even completed one lap. The guys from England knew, as did most people from Europe, but everyone else was struggling, both to keep running at all, and if they got over that hurdle, to control the car with next to no traction.

    I guess we should let this thread get back to tire doping...
