I am considering changing my front tires to turf. Will there be a circumference difference between a R4 and turf 23X8.50X12. Also they will be 6ply for load rating.
No problem at all, I have a set of R4 and turfs for my B2620 which is an earlier version of the 2601. If I'm lazy I only switch out the fronts to turf.
The rolling circumference of the R4 and turf is the same as they are the same size.
