Hey folks. I just assumed that for Senior Briggs everyone uses 7.1 tires on the rear (and hence probably buys the wider rear rims e.g., 210mm) but I see in the CKRC supplemental specs that you can run either 6.0 or 7.1 on the rear. Does anyone run the 6.0s in seniors, and if so, why? I'm prepping Owen's kart for next season, which is currently set up as a junior, so very curious about this before I buy new wheels/tires.
Thanks for any guidance you can provide!

Hey Mike,
Nobody runs the 6 inch to my knowledge. The 6 inch D2 will be a significant disadvantage just from a mechanical grip standpoint.
