Are there any problems i might run into with R1 bar tires on an F3680 and the 4WD? I know some of the bar tires run larger than the turf tires. I plan to change all four to OTR Lawn Trac tires. The factory rear tires are 18x9.5-8 but I'll have to switch to 18x8.5-8 as they don't make that tire in 9.5" width.
Thanks for the help

Get the RC (Rolling Circumference) of the tires you have now and the RC of the New tires and keep them within 2.5% of the original on each or a total of 5% between the both, and you'll be fine. ;)
