Why not just order them and have them installed there. One trip
I know some people aren't huge on discount tire- but I have been buying from them since 2001 and stand by their service. If you are going to be buying tires for multiple vehicles- take time to get to know your local discount tire manager. It will be worth your while. They will price match everyone and put full no questions asked warranties on all tires. They have locations in almost every state as well.
They are not really local. Looked again and they are about an hour drive.
It seems there is a national back order on MT's. 2-4 weeks. What the hell!?
