The 2650 and 3350 share the same tire sizes.And assuming there's no "stock" fix to allow for both with R3 turf tires? I've seen some go with 3350 tires on the 2650 but I'd imagine that's just even more of a problem (wider/bigger).
The "stock" fix is R3 tires on R4 rims. Either than or make installing and removing the spacers part of your annual switch over from winter to summer.
