Should I replace my tires at 4/32 or 3/32?
"Tire Rack's advice is that if rain and wet roads are a concern, you should consider replacing your tires when they reach approximately 4/32" of remaining tread depth." Obviously the tread will wear away over the life of the tire and the volume of its tread grooves will be reduced.
How long does a tire last on a 1 32?
The average tire tread depth wear is about 1/32" per every 5,000-8,000 miles. Yet, it greatly depends on the tire type and the compound used during manufacturing, as softer compounds tend to wear faster. Additionally, driving conditions and habits can also accelerate tire tread wear.
How safe are 7 year old tires?

What is the 105% rule on tires?
The Rule of 105 states that the rim must be at least 105% the width of the tire if you have any chance of re-capturing airflow from the tire and controlling it or smoothing it. This was originally coined by Josh Poertner, who spent many years designing wheels at Zipp.

How many miles is 400 treadwear?
While not even the best UTQG-rating tires can be completely trusted, the tire tread wear ratings guide is actually quite straightforward. To estimate a tread life based on treadwear ratings, you will need to multiply the number by 1000. Therefore, based on simple math, a 400-rated tire should last for 40,000 miles.
What is the penny test for tires?
Take a penny and place it with Lincoln's head upside down between two ribs on your tire. If part of the head is covered, your tires are still in good shape. If you can see his entire head, your tread is worn to 2⁄32 inch or less and it's time for new tires.
