They’re the ‘MG Blues’ as some would call them. They do fairly well with four-strokes because they’re really hard compound and last long which is good for your budget. We ran our LO206 on them all season and they could probably go next season too! They’re the equivalent of the Bridgestone YDS tires and are spec tires here at Norway (CHMS) for our LO206 class. FAIR WARNING THEY ARE REALLY HARD TIRES AND YOU’RE NOT GOING TO SET LAP RECORD TIMES!
Run them at or around 18 PSI and you should be good to go.
If you don’t feel like using the MG blues then go for the spec tire you run at your local track/series.
