We are starting a spec class with the Cup Racers and we need to sort out the tires- as I understand it, HPI's rims are special and if you want to use their rims, you'd obviously be stuck with the tire range that HPI offers currently. Otherwise, you run the Mini rims that Tamiya designed with aftermarket tires. Problem is- if you have the Porsche you'd have to run non-offset Mini rims with a hub spacer if you wanted aftermarket tires right? Has anyone had luck with the optional Soft HPI tire?

Thanks!
