I was owndering if you guys could help me out. I have a 65 c20 and it currently has 16.5 rims and i was wondering if i had to run 16.5 or could i go 16. It has some cookie cutters right not and i just wanna got to some stock steelies and i found some 16 for a good price. not to mention 16 tires are a dime a dozen compared to 16.5. Thanks for your help guys
