When to Replace Your Tires | Discount Tire

There are many signs you may need to
replace your tires. Irregular wear, damage, and weathering can all indicate the need for new tires. However, the most common sign that it’s time to replace your tires is low tread depth. Your car’s wet braking performance depends on having sufficient tread depth. Worn tires can nearly double the distance required to stop on wet surfaces. When tires are new deep circumferential grooves channel water from the tread area to maintain road contact. As tires wear the tread depth and circumferential grooves become shallower, decreasing the tire’s wet weather traction. Independent testing shows that at 4/32″ of tread depth, on wet pavement, a full-size car travels over two and a half car lengths further, before coming to a stop than the same vehicle with new tires. While that may not sound like much, its equal to over 40 feet, about the same length as a standard semi-truck trailer. Tread depth can be measured using a pen style gauge. Place the gauge on the tread surface and press the top down until the
pin touches the bottom of a groove. Read the measurement. Measure three places across the tire, inside, in the center groove and near the edge. The lowest measurement
indicates the tread depth. You can also measure tread depth using a penny. Place a penny with Lincoln’s head down into the tread groove. If you can see the top of Lincoln’s head while looking across the tire surface your tire has less than 2/32″ of tread depth. Tires worn to 2/32″ of tread are
considered legally worn in some states and replacement is highly recommended. Stop by your local Discount Tire

  1. I know this vid is a Discount Tire ad, but something else determines when to buy tires, age. I have had tires on two different cars come apart, one on the freeway and the other in a parking lot. They had adequate tread, but were over the tire mileage warranty and over three years old when they failed. I recently replaced the factory Dunlop tires on my 2014 Mazda 6, they were 40,000 mile tires and had 48,000+ miles on them. Tread was adequate, but I was leery of them because of past history on other tires. I have since replaced them with a set of Hankook Ventus V12 evo2 tires and now feel a lot safer on the road.

  2. I need to buy a set of all season tires and I wanted to ask you which tire brands have the least problems with dry rotting and which tire brands have the most problems with dry rotting?
