How do you determine what size tires to put on a plane
Planes weighs 13.25 lbs and 73 inch wingspan

grass or paved field/runway?

grass field will need bigger tires, personally I'd probably try a couple sizes... maybe start around 3.5". If rolling is a problem you can always go bigger.

My 17# 50CC plane came with 3.5" wheels. You could probably go to 3" unless your field is rough as stated in the previous post.

A Goldberg Cub with a 76" wingspan around 7 1/2 lbs calls for 3 1/4" wheels.

The lightest 3" wheels you can find. You may want to see where you can shave weight off that airplane. 13# is a bit porky for that airplane.

30% of MAC is a good safe start. Cap 21's do not like much elevator throw.
