I'm having a hard time trying to find some rear tires for my Cub 1515 (2003 vintage). I'm getting ready to Winterize her and I thought I would go ahead and replace the dry rotted leaking tires. 20x9x8 is what is on there and apparently these are really hard to find. There are some ATV tires available, but want to stick with a lawn tractor tread.

Through some research including this board some say a 20x10x8 will work just find. I have a hard time trying to comprehend how a one inch larger diameter tire would seal.

Can anyone fill me in on how well a 10" tire would seal on a 9" rim??

Thanks in advance.
