Roger I would recommend that you do install a system they can save you some major problems as you head down the road, I have used the tire pro system for about 4 years it's been improved now with a replaceable battery in each sensor. I have had one tire warning while driving and had time to pull off the road before any damage!
One save it worth the cost of the system.
As Larry mention if you use the search feature on the forum type in "tire monitor" you should find many posting to review.
