Tires: tire compatibility, chevy prizm, concerened

Question
My wife had a flat tire on our Chevy Prizm.  It was Friday afternoon.  I took off the tire and put on the temporary spare.  I took the tire to a tire store to get repaired while we went to eat dinner.  I came back to find out that they could not repair the tire.  Then I priced out a new one.  I bought a new tire, and I went home to put it on.  Only then did I realize that the one they sold me was a 175/65R1482S.  The other three still on the car were 185/60R1482H tires.  Do I need to be concerened about safety, rotating, overall compatibility, etc?

Answer
Yes very much so.  Take that tire back and get a full refund ASAP!

You have two problems.

1- The tire sold to you is smaller.

2- Your speed rating is a lot lower, and is very unsafe.  Note: Tire dealers can not sell a lower speed rating, must be the same or higher.  ( at least here in PA ).

This new tire is very unsafe and will mess up the axle, braking, handling, steering and more.
