This second rule is very important for your safety, which. I had to learn the hard way. Paying attention to tire safety is a must! Check the date on your tires at the beginning of each season. Your tires may look to be in good shape and have plenty of tread, but it is recommended that they be replaced every 5 to 7 years, depending on your use and road conditions. Check your tire pressure before you hit the road every day. Over inflation or under inflation are the main cause for blow outs and tire wear. Speed is also an issue for blowouts and I will not drive over 60MPH, even when I see rigs flying by me at 70! Blowouts can cause you to loose control, but my experience to date has only been damage to the siding on my tow behind RV by disintegrating rubber and steel belts. Do some serious research on the best tire for your rig. I now use Carlisle Radials and have had no issues after 4 years of hard wear. Check the DOT date on the sidewall on your tires to determine how old they are, as I said, looks can be deceiving.
