Low tire track profundity can be a security issue. At the point when the street is wet, low track profundity can make the tire hydroplane, or skim across the outer layer of the water, which can cause you to let completely go. You likewise have less footing in the snow, and the tire is more vulnerable to a victory. Albeit the best method for checking track wear is with a track profundity measure, you can get by with what’s known as the “penny test” or simply utilizing your fingers.

Allow Your Fingers To do the Checking
New tires regularly start with a track profundity of 10/32 to 11/32 of an inch, and they’re for the most part thought about lawfully “broken down” when the track is down to 2/32, however some think about 4/32 as a more secure least.
Practically all tires have inherent wear bars across the track at four similarly dispersed places around the boundary of the tire. These wear bars are 2/32 of an inch tall and normally are in an orderly fashion across the track, yet in some cases they are somewhat balanced from each other.
On the off chance that you run your finger along any of the longitudinal tire grooves, you’ll probably feel the wear bar as a little protuberance. Assuming you find it, any track that stands equivalent to the level of the wear bar implies the track profundity is down to 2/32 — or perhaps underneath (since both could currently be worn out) — and the tire ought to be supplanted. Any measure of track remaining over that can be utilized to appraise its profundity. Assuming the track feels to be about two times the level of the wear bar, you have around 4/32 track remaining.
The Penny Test
The penny (or comparable quarter) test is likewise usually used to assist with passing judgment on track profundity.
Assuming you hold a penny so Abraham Lincoln’s head is overcoming and embed it into a section, the highest point of Lincoln’s head is around 2/32 of an inch from the coin’s edge. So on the off chance that you can see Lincoln’s entire head, your track profundity is down to 2/32 or maybe less, and you’re expected for new tires.
In the event that you hold a quarter so George Washington’s head is overcoming and embed it into a section, the highest point of Washington’s head is around 4/32 of an inch from the coin’s edge. In the event that you can see Washington’s entire head, you’re where you’d most likely need to begin contemplating supplanting the tires.
