I would imagine there will be a grace period and hoping there is, as we still have a few extra HT2 tires. If not that's fine to, we are going to keep racing and doing the best we can. I know everyone thinks open tire rules saves money, but if you ever raced karts you know it does not. The biggest expense in kart racing is tires! You literally have 20 plus sets of wheels and tires just to compete. I will not complain either way. I just want to race!!!!!!
