Tdragger, is that not S directly in front of you. The cowherd from KY?
I run the225 /50. Its about 0.25 less in the total radius of the a stocker Metz. I compensate with a Tuneboy. And it runs right on! Its also about a total 1/2" lesser in width. Plenty of wiggle room. I believe the 245/50 will come close to 1/8" and no more clearances on neither the shaft nor the swing arm.
