It would be useful for those interested, to see where this item is available from. Is it experimental, or fully tested and safe to use? What instructions or warnings are presented? I'm guessing it was created by Brr, who made the 60fps patches. He's not currently active, and his creations tend to be experimental and unfinished.
A proper safe pitstop patch has been experimented with, in connection with future Mods. But it has no realistic purpose in 1960's racing. Tyres were durable enough to survive 2 hours of racing, in almost all circumstances. An F1 pitstop for a puncture could be a 1m30secs, to 3min affair, so not recommended.
1960's tyres were hard rubber. There was no soft compound, so that aspect in this .xml is pure fantasy. Fun to try - maybe? Helpful to racers online - not this one !
