Running fast at low pressure. I learned the hard way.
When I got sick of having a real job, I went to work for AAA. That was a great job. 3 1/2 days a week, long weekends every week. Great bene's. I almost ran the department for the company, as I usually do.
I saw this a lot. People jump in without looking at the tires. A soft tire at speed overheats, and shreds the sidewall exactly this way. Something to think about when you are tempted to drive home at trail pressures! It doesn't matter if the sidewalls are 2" or 6" tall. overheating is the same.
Air your tires up properly, or drive a short distance very slowly!
When I air up, I am using a 110v Porter-Cable compressor. It still takes about 30 minutes to air up from trail pressures with 35" tires to 34 PSI. Often, it is faster to just go home to my big compressor. It is only 10 miles or so. But at trail pressure, I am limited to 45 MPH, in the right lane. I hate it.
Always take the time to air back up! That is why you bought that pump. It saves a lot on tire costs.
Most times when I saw this tire condition, the owner was oblivious. She had no idea that a tire was soft. The soft tire is usually on the right side of the car. If it was on the left side, she might see it. Statistically, most flats happen on the right side, where the low part of the road is, and the driver is not looking at the tires. That is why tires end up looking like the one above. Nails, screws, and sharp objects fall to the low point, the right side of the road. That is the side of the car that the driver is least aware of.
By AAA statistics, most flat tires are on the right rear tire. The level is 75%. 3/4 of all road sedan flats are on the RR tire. That applies to flats on pavement cars and all flattened tires combined. In my experience the statistic is accurate. It does not apply to off-road vehicles. There is a real reason for this. It gives us something to watch out for.
Roads are designed to shed water. The lowest part of a road is the right side. Objects such as nails, bits of glass, and other puncturing objects gather at the low part of the street. In the street gutter. That is where your right-side tires live. The closer you drive to the gutter, the more you expose your right-side tires to these hazards.
A nail laying flat in the road is harmless to a tire. In a horizontal position, it cannot puncture. But your front tire kicks it up. It begins to tumble over. Then your RR tire catches it. The nail is driven into the tread by the weight of your car. Two days later you have a flat tire. It is not magic, it is simple physics.
We may all be really cool guys, but being cool will not remove us from basic physical rules. I have patched the tires on some really fancy Bentleys. The rules of physics do not really care! They drove in the gutter lane, and got flats like the rest of us!
Maybe everyone should drive a 4x4 with plugs in the sidewalls like I do. Both of my brothers got 50K out of sets of Nitto's. I have holed the sidewalls of mine so many times that I will be lucky to get 30K. I often wake up to find flat tires. I air them up every day. I never wheel my truck! My tires have certainly never been abused!
You should check your tires in the mornings. It is a part of my routine! I have a low tire one morning of every three, at best. I often wake up to a flat tire. I air it up and go! The compressor in the truck will take care of the rest of the day. I drive mostly 75 miles a day or more.
There is a simple cure; You always have to put some junk in the car. A briefcase, whatever. Put it in the passenger side, and look at the tires. Then get in the drivers' side, and look at the tires.
If you do this every day, you know how the tires are supposed to look. You don't need a pressure guage to know when a tire is soft if you pay attention. Tire pressures are checked every 3000 miles if you have good maintenence. In between, it is your job. You should know how a normal tire looks. If it looks soft, don't drive on it!
Maybe you are late. You will be a lot more late after shredding a tire, plus the cost of one or more tires. It pays to glance at the tires every morning! They are most vulnerable to nails every mile. Just look at them every morning! It's not that hard! It will save you a lot of expense and trouble.
