I have 2 sets for my 1880. The turfs that came with it for cutting grass. Larger R4’s (for the 23S) for winter duty. The don’t make R4’s for the small rims that come with the 1880. Not exactly fun but I get about 4 inch lift with the larger tires. I don’t fill the tires. Works fine without. I remove my mower deck for winter duty. If you do this, buy the plate that mounts underneath to protect from crap that could damage underneath. Can’t remember the company I ordered it from. Someone here will post the business. Not that expensive. If I find it, will post it.
