The E4 of the tires of the car indicates that it is a verification mark that meets international standards;

There are three letters starting with "T" on the side of the tire, Treadwear stands for Abrasion Index, Traction stands for Traction Performance, and Temperature stands for Temperature Index. The first number is the tread width of the tire, the second number represents the thickness of the tire, and the car tire R indicates that it is a radial tire.

The number after the letter "R" refers to the wheels that can be fitted with this tire.

That is, the aluminum alloy wheels in the middle of the tire.

Haven't seen what you said.

The E1 E4 you are talking about is estimated to be the ** tire model! Nothing really means.

That's called dot, which is the manufacturer's **.

Different companies and different brands have different production**.

I'll take Michelin as an example:

Y5-Shenyang Factory.

7V-Shanghai Factory.

W8 - Thailand Factory.

ed - Spanish factory.

I don't know what you're talking about, I've never seen this symbol on a tire.
