Lo206 Rear Tire Dilemma

I race only in Michigan, I’m running in the Lo206 SR class. I’m 6’3" tall 218 lbs. My kart comes in about 17 lb’s over weight. We can only run MG Red tires any size. Unlike some of the forum answers out there in Google world my question is simple:6" or 7.10 for the rear? Straight up what width is in the winners circle ?
What’s best width for a tall heavy racer ?

Depends on many factors, I prefer to run 7.10 and usually run quicker then 6.0 at my local track with tighter corners and big brake zones even on a 206. On a larger track, I am faster on 6.0 tires where roll speed and not grip plays a larger roll into how fast you come off corners.
