I contacted 2 local shops, firestone, and pep boys. All of them wanting anywhere from $100-80 to mount and balance some all seasons on 15" wheels. For shits and giggles I called the Toyota Dealer... Their price? $60.
YEP. After calling around to see who could give me the best price on mounting and balancing 4 tires without tire pressure monitoring, the best price came from my local Toyota dealer.
Needless to say I was pleasantly surprised.
