2000 Honda Recon, need info on ordering back tires and wheels

Hello everybody I’m new to the forum. I am finding it very confusing trying to order some new tires and wheels for my sons Recon. It doesn’t have stock tires or rims. Tire size is 22 x 12.5 – 9 and rim doesn’t have any info. Anyone know where I can find same tire size and rim to fit? Thanks in advance.
