Tires: Tire Size, tire failure, chrysler town


Question
Thanks for the answer!  I have contacted the installing tire dealer and they have agreed to replace the tires at no charge (they admitted that they made a mistake).  I will have the tires changed, but am curious as to what would/could happen if the incorrect tires were left on.

-----Question-----
I just had the tires replaced on my 2002 Chrysler Town & Country.  The original size was P215/65R16.  The tire dealer "mistakenly" installed P215/60R16.  Does this make a difference in safety or handling?  Should I have them replaced with the original size tire?

Peter,

Yes!  Take the vehicle back and point out their error.  

Answer
Peter,

What could happen?  I like to think in terms of risk.

There is an increased risk of tire failure as the tire would have to carry a larger percentage of its maximum load.  While the probability of a failure is low, the consequences might be tragic.

There is also an slight decrease in handling and ride performance, again, a low probability, but in this case the consequences are low as well.

Hope this helps.
