I was not a tire cover believer but I am now! A few years back we had a major blowout causing over $6,000.00 in damage. Thanks insurance company you did a good job and so did Good Sam Road Side Assist.
From this we learned that you need to keep all your tires at correct pressure all the time. So we added monitors on each tire and an alarm goes off if the pressure drops or rises above a set range. Please note cold and hot temps can make big changes in tire pressure.
Second, age matters a lot. If tires are over 5-7 years old they probably should be replaced, sooner if you see damage. This is an item you need to budget for, tires are not cheep, nor is the damage they can cause if they blow do to age related causes.
Third, tire covers are a great low cost addition to reduce solar damage. So if we park for more then one night we put our tire cover's on. Reducing solar damage even if only 25% of the time can add life to your tires.
Just our opinions. Feel free to add your comments.
