I agree with all the posts.
But, if someone doesn't post a mistake. How will
a Newbie like myself, having been researching for a year and understand from reading different theards about tires and when to replace tires, or what can happen if not heeded. I know i will file the information away. What can happen if you do not change your tires every 3 to 4 years. It could help another Newbie or two down the road, to take care of their tires. Nobody can plan a blow out on a good new tire, to many varibles to mention, other than doing the above to minimize the chance of a blowout and the damage that usually occures.
Just my .02 cents,
