Oil At Temp light flashing after roughly 30 miles of driving.

What is your question?

It first started off when my back right wheel was changed a while ago, turns out a tire a inch smaller was put on by accident and took chunks out of the bearing to the point it almost completely seized up. The only reason I took it in was that the cars oil at temp light was coming on and it was pulling hard to the right and making noises. Got the tire replaced but now after 30 miles of driving it comes on luckly I had just reached my house but I am not sure if it is safe to take it to work and risk another break down. Transmission oil and its filter have been replaced. Any ideas on what to do?
