Well the wife used her Amazon-fu and found some for 60 bucks with free prime shipping... They're Sumic brand, never heard of them before but the reviews are 4.5/5 and I haven't seen a negative review yet. I can get them mounted and balanced for 10 bucks a tire at the on post DIY shop, and they've even got an alignment rack I can use...

I hadn't even thought of Amazon. Lol
