Used b2410 turf rims with incorrect tire sizes

[Jgolds]

Hello. Just picked up a b2410 and saw it does have incorrect tire sizes. Now I don’t really like the tires as they are older so I’m planning to replace them but for the time being want to see if someone is able to run the conversion on the sizes and even see if they will work with 4x4
Here’s what’s on it
24x9.50 r12
35x12.50 r15
Thank you
