Tires want to swap tires - r4 for r1 grand L40

[jonbob]

Hello, Recently purchased a used L5240. It came with R4 tires, but i would prefer to run R1 ag style. Mostly I need the width between rear tires to increase more than the R4's can be adjusted to. Anyone in northeast area who would be into swapping? Tires are in excellent condition. I can deliver and pick up. Tires are 10-16.5 front, and 17.5-24 rear. Thanks
