OK! My old 9.50 x 16.5 Bridgestone tires finally have bit the dust. Went to Sears last week for new ones only to be told that the 16.5 tires are no longer available. Since them, I found out that only Firestone manufactures the Transforce 9.50 x 16.5 tire now at about $190 each. I could do that, BUT should I get 16" rims and have more tire selection available? And what would the rim size have to be? It's a 8 lug design. I'm sure that I'm not the first one with this dilemma. What has been done in the past and what works? What do my fellow enthusiasts think? Thanks!
