One of my troubleshooting maxims is - What just happened?

Sounds like a tire problem.

Did you look at the tires before you put them on?

I always pick stones out and check for hardware, then I put all 4 tires together in the position that I intend to use them and check for wear, etc.

I would jack up one side inspect and swap front and rear - then take her for a test drive.

If that does not reveal the problem, do the other side.
