AboutBrett Harrell Expertise I can answer questions about tire brand applications without Brand bias or company loyalties. Any bias that I may have is based on practical and real world experiences. I will answer questions about tire sizes, wear, speed ratings, load indexes as well as most other questions about passenger, light truck, tractor along with RV/trailer & medium truck tires. Please include the type of drivetrain for vehicles: 2WD, 4WD, AWD and if the vehicle is lifted or lowered. If you have a tractor question please indicate if it's 2WD, Front Assist or 4WD.
Experience 1) 2 years as a lead tire builder and 7 years in quality assurance diagnosing failures at the plant level and in the field. This work was performed for a major tire manufacturer. 2) 18 years in sales to the end user of ALL types and brands of tires.
This might sound like a dumb question, but here goes anyway.
How do you read the DOT code
Answer Jim,
Actually this is a frequently asked question. Located after the letters DOT there are a series of number and/or letters that will providee you with the following data:
The 1st 2 letters, numbers or combonation of indicates WHO and Where the tire is built.
The next 2 letters, numbers or combonation of indicates the SIZE of the tire.
The next letters, numbers or combonation of indicates the BRAND of the tire.
The next 3 or 4 numbers indicate the WEEK and YEAR the the tire was built ( 3 numbers for the 90's and 4 numbers for 00's )
