Tires: 91h or 91v tires, dunlop sport, sam s club

Question
I bought 2 205 55 16 91v dunlop sport signature tires online last month and 2 dunlop signature 91h tires yesterday at Sam's club and the clerk said there is no difference between the 2 kinds of tires. However, when I got home we noticed the thread pattern and the sidewalls are different, should I take them back and get 91v's to match the new back tires?

Answer
Gary,

There is a possibility that you will not be able to match the tires through Sam's Club, but you should make the attempt.  Sometimes, the tires offered by the various outlets are different - which is why you should buy all 4 at the same time.

If you can not get them to match, do the best you can.
