For me here in Florida, 57mm front 59mm rear is what i use for QLFing only or if there is almost 0 tire wear, an traction is stupid high.Depends on the mains then, i decide what size will work best for me.Also i get with the guys that run before me an see how much wear they had ,and what their tires look like when they come off the track.But please keep us up dated.
