If anyone wants to take a stab at any of the following 5 questions, your feedback will be appreciated.
TIA


How long is the recommended life of the TireFilt sealant?
Does the sealant have a part # or is aftermarket recommended?
Can someone explain any myths or mis-information regarding the use of Nitrogen in the wheels? For example, can regular air be mixed when filling tires? (I'm guessing yes)
What aftermarket rims work will with Crossfires when mounting winter rubber?
I have read about the "Throttle re-set" and "Syncronizing ESP". Are these recommended by users and are their any other "settings" I need to know about?
