Rubber tires last pretty good as long as the rules will let you run specific inserts and compounds to meet or exceed the temperature of the track.
I prefer Sorex in that aspect.
But in all foam is my favorite. As long as your track will allow it and theres enough on the band wagon, to my experience its overall cheaper.
The trick is to run 45 shore or some thing like that like the gas guys run, you just have to make sure of the widths because some cars wont handle 30mm rear tires. Research the car vs. tire and weather they are adaptable. May have to make some mods? Or purchase 28mm widths.
If you choose to run indoor carpet tires they will wear faster. And even faster if you use traction compounds I never used traction comounds with foams out side.
The good part of using the indoor carpet tires is that if you do indoor carpet foam they will work indoors with out truing them to size which wastes a lot of foam.
If you don't run indoor carpet foam, I would recommend compounds like the gas guys are using. The harder the compound the longer they last with the lighter car.
Good luck most tracks don't allow foam electric for some reason?
The nice thing with foams you don't only have temperature choices, but traction choices. If it dusty, softer compounds will work even if its to hot for that compound.
With rubber to my experience the temp limits the compound to the traction level. If the traction requires RP 27's the temp may require Sorex 32's.
In this case rubber or foam the tires will wear faster. I Would rather have foams in this situation.
Trail and error, when the temperature comes into play.
Lots to consider when choosing tires, and foams have a lot more options.
