Ads give you 2 extra tires every 24 hours. Use them wisely, sometimes it's better to wait for a new location to unlock before using them.

Also when you watch the ads you have to use these extra tires right away, because when tires get refilled after 8 hours they only get up to 5 tires, wether you've used the extra tires or not (i.e. you can potentially waste the 2 free tires by not using them before regular refill).
