I have a 2010 z8 that I'm thinking of upgrading my steel wheels on my trailer to aluminum. It's a tandem trailer. What are guys using for tire and wheel packages aftermarket wise? I know that some car wheels will work but I'm concerned about making them fit with bearing buddies. I like idea of towing with a automotive tire vs trailer tire. And what is the bolt pattern? Thanks. Advice on places/websites for prices are great!
