For me, I could easily run MG Yellows for 2 races. On several occasions this year I ran 1-race old MGs for practice and there was still plenty of tread wear left. I think the MGs maintain their speed pretty well. I used new tires for each race mainly because new MGs give you a bit of an edge for qualifying. I plan on using my Bandimere tires at IMI this weekend.
My suggestion, at least for CSC races, would be to mark the tires and require that they be used for 2 races. In other words, every other race would be a “new tire” race.
Maybe other people would have issues with this and this wouldn’t be workable. I’d be interested in hearing what others have to say.
Also, though it would be useful to save money on tires, I don’t think that’s the big thing keeping new karters out. I think it’s 2 things:
1. Cost of getting in – I estimate it cost me close to $10,000 including the cost of a used kart, all associated tools and accessories, driver’s gear, and spare parts.
2. Lack of promotion of karting – I lived in Colorado for 3 years before I heard anything about karting here. I just happened to hear from a coworker that he went to a birthday party at IMI.
