Dots on Tires meaning guide 2025
1. Introduction: Why Tire Codes Matter
Each tire is marked with a series of letters, numbers, and symbols that contain essential information about its size, construction, load capacity, speed rating, origin, and date of manufacture. Understanding these codes helps you:
• Choose the right tire for performance, comfort, and safety
• Avoid buying old or expired tires
• Stay compliant with UAE road safety laws
• Prevent mismatches that lead to blowouts, poor grip, or excessive wear
⸻
2. Tire Size Code (e.g., 205/55R16)
This is usually the first code visible on the sidewall.
• 205: Tire width in millimeters
• 55: Aspect ratio (sidewall height as a percentage of width)
• R: Radial construction
• 16: Diameter of the wheel rim in inches
A 205/55R16 tire fits on a 16” wheel and is 205 mm wide. It’s commonly used for sedans.
⸻
3. Load Index (e.g., 91)
The load index tells you how much weight the tire can support when fully inflated.
• 91 = 615 kg (1356 lbs) per tire
• Multiply by 4 for total vehicle load capacity
Refer to load index charts to ensure your tire can handle your vehicle’s weight, especially SUVs and off-roaders in the UAE.
⸻
4. Speed Rating (e.g., H, V, W, Y)
The speed rating shows the maximum safe speed the tire can handle:
• H = up to 210 km/h
• V = up to 240 km/h
• W = up to 270 km/h
• Y = up to 300 km/h
For most UAE roads, V-rated or W-rated tires are standard for performance cars.
⸻
5.Dots on Tires Code and Manufacturing Date
The DOT (Department of Transportation) code is one of the most important identifiers. It ends with a four-digit number that reveals the manufacturing date:
Example:
DOT XXXXXX 2222
Means the tire was made in the 22nd week of 2022
• Tires over 5 years old are not recommended
• Tires over 6 years old may fail RTA inspections or be rejected at Tasjeel
⸻
6. UTQG Rating (Treadwear, Traction, Temperature)
Developed by U.S. regulators, the UTQG system has 3 components:
Treadwear (e.g., 400)
• Higher numbers mean longer tread life
• 600 = longer lasting than 300
Traction (e.g., AA, A, B, C)
• AA = highest wet traction
• A = very good
• C = lowest acceptable level
Temperature (e.g., A, B, C)
• A = best heat resistance
• Important for UAE heat and high-speed highway driving
⸻
7. M+S, 3PMSF, XL, RFT and Other Symbols
M+S (Mud + Snow)
Not designed for deep snow but shows some all-season capability.
3PMSF (Three-Peak Mountain Snowflake)
Rated for severe winter conditions. Rarely used in UAE but important for European/GCC exports.
XL (Extra Load)
Tires with higher load capacity — ideal for SUVs, 4x4s, or vehicles with heavy cargo.
RFT (Run Flat Tire)
Tires that let you drive short distances after a puncture. Common on BMW, Lexus, and Mini.
⸻
8. Country of Manufacture and Legal Compliance
Look for markings like “Made in Germany”, “Japan”, “Thailand”, or “China” — depending on the brand.
Also look for GCC Conformity Mark (G-mark) or E-mark, which may be required for import or road use in the UAE.

9. How to Use Tire Codes When Buying New Tires
When purchasing tires:
• Check the DOT code — avoid anything older than 2 years
• Match load and speed rating to your current tires or better
• Choose proper treadwear for your driving style
• For desert/off-road: go for A/T or M/T with higher sidewall and XL rating
• Verify sizing to prevent rubbing or speedometer mismatch

10. Common Misunderstandings
• M+S ≠ full winter tire
• XL doesn’t mean bigger size, it means more strength
• DOT codes can be fake — buy only from trusted sellers
• Higher speed rating doesn’t improve performance unless your car supports it
• Date of manufacture ≠ date of use — tires age even when not installed

11. FAQs
Q1: Is a 5-year-old tire safe if it looks new?
A: Not recommended. Rubber degrades. It may pass inspection but is less safe at high speed.
Q2: Can I use different load or speed ratings?
A: Only if it’s higher. Never go lower than factory recommendations.
Q3: What’s the difference between 91H and 91V?
A: Same load, but V can handle higher speeds than H.
Q4: Where is the DOT code located?
A: On one side of the tire sidewall, near the rim, usually starts with “DOT”.

12. Final Thoughts
Every symbol, code, or dot on your tire has a meaning — and knowing these codes means driving smarter and safer.
Before your next purchase, check for:
• Proper tire size
• Correct load & speed rating
• Valid DOT date
• Reliable UTQG score
• Legally compliant branding
Whether you’re driving the Sheikh Zayed Road, hitting the dunes in Liwa, or planning a GCC road trip — your tires are everything.
