First time racing indoors coming up at Emma Mo this weekend. What should I do to Maxxis tires that are prepped internally (not sure with what) then we gave 3 good coats of TT black sand on Tuesday? Tires are are at 52-55 Douro now. Should I PRW with Orange? How many coats & how soon before? Are indoor tracks considered low, med or high bite? How do they usually change from heats to feature? Big thanks in advance!
