I don't race in Britain but we have control tires here in Germany as well. I really like that fact as it makes racing that much easier and you can buy in bulk, which cuts the price down nicely on Proline and Losi tires.
The question is whether a limit is really that sensible because even if I use tires for two runs only before using new ones, the used ones are still plenty good enough for practise or even for different tracks with different grip levels.
In the end I can use 5 sets of tires for a national which will be absolutely great for club racing or practise afterwards.
