C-Hing moon, Just to share experience.
As F1 Tamiya and RIDE rubber tyre "wheel rims" are quite brittle (easily cracked), making tyres life much shorter. Here is a method that I experimented should save your broken tyres hopefully 
When the rubber and rim start to split, I used Lexan Car body Repair Glue (can buy in any RC car shop in KWS) to apply around the join between the rim and the rubber. It does not look nice but it works very well. I tested this technique on both Tamiya Rubber tyre and RIDE rubber tyres, as rims from both brands are brittle (easy to crack). See photos below, I used the tamiya tyres to end of life.... .
Once the glue dries, because it is slightly flexible, it stretchs a bit with tyres. So far all my repaired tyre/rims worked to the end of life the tyres (worn till hole comes thru), and no more "re-glue" required after each play. So far so good 
Hope this helps all... , let me know if anyone is successful with this technique too.... be interested to know.
