I spoke with Jim from acme and he put me on the 15.5/11 and I should have returned it with in the 30 days but I didn’t want to pull my boat out of the water(30min each way 70$ launch fee and $7.49 a gallon and I have to tell my wife she’s doing great when she’s got the trailer on the curb)
He was very concerned about my elevation and extra weight. 15.5/13 here I come!
