Drivers are just realizing you can tell if tires are prone to blowout – never buy if you see worn ‘black spot’
A car expert has revealed how to tell if a tire blows out with just your eyes.
The car enthusiast shared his advice in a TikTok, noting that tire condition isn’t the only factor that can lead to this traffic hazard.

Cong’s (@conggeshuoche) video clip shows the gearbox kneeling in front of a car’s steering wheel, informing viewers that each tire has a maximum speed capacity.
He clarifies that exceeding a tire’s recommended maximum speed increases the risk of a tire blowout.
Next, Cong shows how a tire’s speed rating uses a single capital letter on the sidewall next to the long specification code.
The vehicle Cong examines in his clip has the letter H, which translates to a top speed of 130 miles per hour.
These speed limits range from 68 mph to 149 mph and more.
Cong then explains a tire’s three-T index, a section of numbers that rate the product’s tread wear resistance, traction and temperature resistance.
He says that a tire’s treadwear resistance range is a three-digit number, and the higher this number, the slower the tire wears.
Cong clarifies, “For family cars, we usually choose a tread wear resistance rating of 300 or more.”
The car expert then highlights the traction range of the three-T index and explains that this rating uses a single capital letter – with A being the best and most common letter in family vehicles.
The traction values show how well a tire behaves on wet roads and is in the middle of the three-T index.
The last part of this three-T index in Cong’s video is the temperature resistance of the tire.
Temperature resistance labels use a single letter, like a traction rating, with A representing the best quality.
Temperature resistance is critical for a tire as it indicates how well it performs in high speed situations such as highway driving.
But Cong didn’t stop pointing out ways to avoid questioning yourself when assessing tire quality.
He stressed the importance of checking the black spots between a tire’s tread.
These small vertical black spots or stripes, called wear strips, indicate if a tire’s profile is too low to maintain traction on the road.
If a tire’s tread matches one or more of these black wear strips, it is unsafe to drive.
