What size tires are best for MX racing?

[Ty's400]

I was wondering what size ITP Holeshot MX's are best. I've been considering the 19x6-10 for the front and 18x11-8 for the rear which would be the best for the rear 11-9 or 11-10 and for the front should I go with the 20's thanks for your time

go as short as possible but you might want bead locks. Just remember though with those short tires your gonna hang up all the time. I know I do but it handles so much better. I have itp holeshots and think they are great but the tires are so short they keep getting knocked off the bead cuz I don't have any bead locks. Also they wear really fast.
