It's felt Paul. You know it's that kind of protectors that can be posted under the chairs to avoid scratching wooden floors (sorry for my English, I don't know if I'm using the right expressions. I'm trying to do my best). I have found them in a chinese shop (20 units=1 euro). They are the same diameter as slot wheels and if you join a pair, they're also the same thickness. Afterwards, I searched some visual information about tyre warmers in Internet and I printed the different colour labels and glued them around.

Cool scenic items,well done.
Just in case someone needs functioning tyre warmers,the member of the greek modelteam forum vassiliosapr posted an article about making them,it is in greek but the photos will tell the story,and then feel free to ask if there's something you dont understand.

Alexis in Greece,

Now, do functioning tire warmers actually make a difference for slot racing?
It would be interesting to see some test data with lap times before and after warming the tires (letting the tires cool before the second test, of course).

Cheers!

I couldnt say as i have not tested tyre warmers,it is in my plans.I have a couple of indications though that point to this direction.
-the local club track is housed in a garage heated by a stove only when we are present and it follows ambient temp variations.Recently he had an abrupt temp drop from 25 on wednesday to 10 on friday.Cars were initially .6" slower on friday and when the stove was turned on times were 2-3 tenths slower but noone could reach wednesdays times.

-I have been experimenting with tire conditioning fluids for quite some time now.I once noticed that a certain cocktail with Ninco tires had a particular behaviour:after 7-8 min running lap times decreased significantly.I accidentally touched the tires and they felt warm.Unfortunately i had no temp gauge to measure.And what is most unlucky,it was first time cocktail and i lost
my notes so i could not replicate it.

There is evidence that temperature makes a differance to tyre grip.

A good example is bends that can be taken flat out once the tyres have warmed up but not on the first lap or two from "cold".
I've not seen tyre warmers used. The tyres seem to warm up in within 10 seconds and seem to cool down when standing for no more than 30 seconds, so the effect of tyre warmers might be too short lived to be worth much. Also at a lot of international races the car is in parc ferme anyway, so it wouldn't be possible to use tyre warmers.

Has anybody tried tyre warmers?

Could the lap time difference be the temperature of the track not the temperature of the tires?

Tires do get hot when truing so maybe they do get warmer when running but they have almost no mass so would cool down too quickly to be measured. As their mass is very low any attempt at warming would suffer the same fate.

I have witnessed 1:1 bikes on track days they leave their bikes with the warmers on for up to an hour to allow for heat soak. Again slot car tires would be cold before anything could be gained.

Unless they were wheel warmers for alloy wheels which might keep heat for a bit longer. Maybe a small flashlight bulb inside each wheel but I fear the amperage would be too low. Best found with a cursory look is 6.5w. Enough? I don't know.

I'm more interested in the temperature of my beer than the temperature of the tires.

Thanks, GregK, for the "nudge".
I have a pile of electronic parts for ideas I have in my head and on paper, but no track space yet and a pile of cleanup and renovations (window replacement and bathroom reno) to do before I can "play". So spend most of my spare time on this forum learning, commenting and dreaming up more ideas to test (i.e. anti-collision ... almost there in the idea stage).

However, not to hijack this thread...
It seems what started as a scenic item has evolved into a functioning item that may actually have merit. But I wonder if the gains will be scaled to 1/32nd of the 1:1 experience?

Cheers!
