Default Pre meeting tyre prep

So I've worked out my tyre process, but I don't have power at the track, or to much time to do it.

I was wondering if it's worth doing the night before? I have enough sets of tyres to have one for each heat and the final. My main concern is putting to many heat cycles into the tires.

You can't heat the tyres before raceday as that is a total waste of time.

Just clean them up and possibly apply some additive. THen wrap them in cellophane and wipe of the excess before running.

I think I understand what you're getting at. I was involved in 1000cc Superbike/Superstock racing in the past, and for a privateer rider 7 heat cycles was the maximum before the tyre was done, as the oil was gone from it. Obviously the top guys had new tyres for every practice session..no problem if you have a tyre budget of, say 5000USD for the weekend..

TBH I'm not sure how it translates to TC. Outdoor I found 4 or 5 runs and they're past optimum. If its a competitive field the tyres need to be within that window, no doubt. Indoor is a strange one though as the track evolves in a different way. If there are a lot of drivers and the grip really comes up I found good performance sometimes with particular brands by using warmers and no additive whatsoever, just using the additive laid down by the other guys.

Pre treatment might not be the best solution as the amount of time the additive is applied for has an impact on the performance on track, and often short applications of 5 - 10 minutes without heat can give better results than baking the additive for 30 minutes, it all depends on how the track is evolving during the day, its temperature, the type of additive and of course the wheel/tyre/insert combo itself.

In my experience, pre-treating tyres with additive makes them super, super sticky.

I did this by accident once with sorex 24 and LRP carpet additive for an indoor series.

I left the tyres in film for about 2 or 3 months and used them outdoors on tarmac, without warmers in very cold,windy conditions.

They hooked up very well!

However, for indoors I suspect the same tyres would have grip rolled the car.

If you are using used tyres, clean them off, but dont treat them with additive IMO.
