I have searched the archives and found some old stuff on the 20x7.00-8 tires but there doesn't seem to be any current info on possible replacements. I need to replace my tires ASAP since it appears that a belt or something let loose in the tire causing a big bubble on the outside so the plane is grounded until it is replaced. I don't care too much for the big Nancos and would like to keep the original size if possible. Other than the $100 Desser tires on Ebay, are there any other affordable replacements available?
