I've only had tyres completely split on my G1 Cliffjumper (which I replaced w/ tyres from a reissue), and Robots In Disguise Optimus Prime and X-Brawn. The RiD toys were notorious for using inferior quality rubber; if anyone is thinking about back-collecting RiD toys, I strongly recommend getting the Japanese Car Robot versions instead. The only downside is that Car Robot Super Fire Convoy's chrome is more prone to chipping than RiD Optimus Prime's.
There's a video by rocketpuncharmy on YouTube on how to treat your rubber tyres. I recommend watching it.
