When you own a vehicle, you will want to keep it in the best overall condition possible. Part of this includes inspecting the tires and other parts of the vehicle. The tires should be checked for proper air inflation, tread wear, and overall condition. One issue to inspect is dry rot. This can be caused by inactivity, low tire pressure, and excessive heat. These are the primary culprits that cause automobile tire dry rot. If you notice little cracks running along the sidewalls of the tires and running all the way to the tread, you may be experiencing a common phenomenon that occurs in stagnant cars.

Signs of Dry Rot on the Tires

Rubber and plastic materials naturally degrade over a period of five to six years depending on the climate, temperature, humidity, the use and storage of the vehicle, and the air pressure levels of the tires. Dry rot is indicated by hard and brittle surfaces on the tires. As the oils in the rubber begin to evaporate, the chemical bonds break down, leaving a dry tire behind. If you notice this, make sure to bring the vehicle in as soon as you can so we can inspect the tires for you. Inspecting the tires is important because they are the only part of the vehicle that will have direct contact with the surface of the road.

Why Dry Rot Occurs

The most common causes of dry rot include low inflation of the tires, storage near excessive heat, and also lack of use. Constant exposure to sun can speed up the effects of dry rot upon the tires, so if your car sits for long periods of time in the summer, chances are your tires will deteriorate quicker. If the tires were manufactured several years ago, they could be wearing out, even if the tires have not been on your vehicle the whole time.

Preventing Dry Rot on the Tires

If you have to store your vehicle for long periods of time, ideally store it in a climate-controlled garage. Also make sure to keep the tires inflated to the manufacturer’s recommendations. You can also store it with boards under the tires and remember to check the air pressure at least once a month. If you notice any signs of dry rot, contact us to bring the vehicle in. In most cases, tires with dry rot are probably not safe to drive on. Around town, you may have a little time before you need to replace the tires. Once the cracks reach the cords of the tires, the heat of long distance driving will cause the rubber to expand and the tires to actually break apart while driving. No matter what issue you notice with your vehicle, make sure to bring it in as soon as you can. We will inspect the parts and components of your vehicle. This way your vehicle can get back to being safe and reliable when you drive it.
