If you are going to be racing on painted surfaces it is essential to keep the track surface clean. We run predominantly on board tracks and it always takes at least 70 to 80 laps on each lane to get the track flying, This is done as guys are turning up for the start of racing.
A short cut is to sponge the track over with a DAMP sponge or rag, rinsing the sponge regularly. Take care not to rub off the 'Blue Groove' at the entry and exit of bends which is building up from previous tyre wear
After that, you should be able to run most of the commercially available tyres to great satisfaction. Ninco. SCX. Scalextric and Pro slot all seem to work well. Well enough to have some cars tip over in the corners from too much grip!
Ribbed (grooved) tyres also have their part to play. I have a set of ribs and a set of slicks to fit all comp cars, practice will tell you what is needed. Another phenomenon is that wide tyres tend to spin more than narrow tyres, Unlike the real thing, tyres can be too wide! Narrower tyres exert more grip as the model weight acts on a smaller surface area, but too narrow will present handling problems. Find the best width for the model by experiment.
A warm day will see tyres start to work long before the same on a cold day (believe it or not).
If you get into the additive cycle you may firstly be unpopular with some track owners and racers, secondly you will be adding extra time to your pre race checks. It has also been my experience that treated tyres start to go off in anything but short races.
Lastly, some people like to dress their tyres with the sticky side of masking tape or similar. Great for getting you off the line first but if you deslot in the first few laps (or get deslotted) you will find after you run through the dust on the edge of the track you will be slipping and slidding for the next five laps as the dust sticks to your tyres!
I have found the best reliable combination to be firstly getting the correct tyre choice and secondly to keeping the tyres spotlessly clean by wiping with methylated spirits or preferably a pure hydrocarbon like shellite (similar to lighter fuel) to keep the rubber spotless. Then if your in the marbles nothing sticks to your tyres.
Just to totally loose you all, different tracks ie, twisty tracks, straight tracks, long or short circuits, have different tyre requirements, so if you are a club racer, get to the venue early and start practicing, get your tyres sorted before all else.
But again most of all ensure your track is clean and tyres will finish the job.
