Run a decent set of rims and there's not an issue with rubber tire rims. There were some problems with some of the CS rims from about this time last year to about August, but it seems like that problem has been taken care of. I still see more people chunking foams than I see rubber rims being cracked. I think the tracks going to spec tires also made that problem seem worse just because there were so many people running one manufacturer's rims. I have never broken or cracked a Tamiya rim, Schumacher, or Ofna. The only ones I ever had issues with were some Take off rims (I don't know which these were as the rims weren't marked) and Jaco rims. The Take Offs from back then were prone to center-punching the hex out, while the Jaco's were brittle and cracked. Again, 3 sets, 12 tires, for a total of 11 runs versus 1 set of rubber tires that would have lasted all those runs and then some...
I know there are people that can true tires at the track, I just hate asking people for that stuff and inconvieniencing them. 2.20 is what 4 people told me to start off at, so that's why I started there.
