probably 15" diameter, 6 inches wide, 6 ply thick? the manufacturer or
previous user picked those out. you might be changing the clearance to
the ground, making tractor unsafe?

My original tires that came on my lawn tractor were size 15x6.00-6.

I'm not sure what these numbers are (diameter, width, wheel size ?)

Can I use other size tires on my existing wheels?

Thanks.
