In my race strategy it will be say: option, option, prime, option. I think great! I only used one set of option tires during qualifying (didn't get into Q3.) and think that out of the 5 sets they will certainly not give me my 1 worn set. And of course on my last stint they give me the worn tires. They've done this three times to where I now mid session save before diving into the pits just to ensure that if they do add the worn tires I can reload and switch say to primes to make sure that I get fresh tires. How can I make sure that they don't put on my worn tires as there is only an option to select which tire set to use for the starting tires after that its all chance.
