Mine are also set as wide as possible. I have not experienced any problems with them set wide. My dealer only preps the new machines with R1's on the wide rim setting for customer safety and stability. I think you will be glad you did.While installing new rear tires today....I decided also to set my wheels as outboard (wide) as the rims would allow. Previously they were at the narrowest setting and the tractor has always felt more than a little 'tippy' in off camber situations.
I was amazed to find that I gained an entire 12" of overall width which dramatically improves the 'seat of the pants' feel for stability.
Very little of the tires are still under the fender-wells now, so no doubt I'll be throwing some mud on myself at times.....but its worth it I believe for the added safety.
It also greatly increased the clearance between my 3 pt. turnbuckles and the tires.....which before was quite crowded with certain implements attached.
