Other Important Tire Specifications
UTQG Ratings
Uniform Tire Quality Grading rates tires on three factors:
- Treadwear: Comparative rating of tread durability (higher is better)
- Traction: Grip on wet surfaces (AA, A, B, C with AA being best)
- Temperature: Heat resistance (A, B, C with A being best)
Manufacturing Date
Found in the DOT code as a 4-digit number:
- First two digits = week of production (01-52)
- Last two digits = year of production (e.g., 2225 = 22nd week of 2025)
- Avoid tires over 6 years old, even if unused
Load Range & Ply Rating
Especially important for trucks and SUVs:
- Indicates tire strength and load capacity
- Ranges from B (4-ply rating) to F (12-ply rating)
- Higher ratings needed for heavy loads or towing
Important Note
Always match or exceed your vehicle manufacturer's recommended load index and speed rating. Using tires with lower ratings can be dangerous and may void your insurance coverage in case of an accident.
Matching Tires to Your Driving Style & Conditions
Finding the perfect tire match requires considering your vehicle type, driving habits, and local climate. Use this guide to narrow down your options:

Sports Cars & Performance Vehicles
- Prioritize grip, handling, and responsiveness
- Summer or ultra-high performance tires
- Consider separate winter set if in cold climate
SUVs & Crossovers
- Balance comfort with capability
- All-season or highway tires for primarily on-road use
- All-terrain for occasional off-road adventures
Trucks & Off-Road Vehicles
- Consider load capacity for hauling/towing
- All-terrain for mixed use, mud-terrain for serious off-roading
- E-rated tires for heavy loads
Climate & Seasonal Considerations
| Climate Type | Recommended Tire Strategy | Notes |
|---|---|---|
|
Warm Year-Round (Southern US, Desert regions) |
|
High temperatures can accelerate tire wear. Look for tires with good temperature ratings. |
|
Moderate Seasons (Mid-Atlantic, Pacific Northwest) |
|
Focus on tires with good water evacuation for rainy conditions. |
|
Cold Winters, Mild Summers (Northeast, Upper Midwest) |
|
The safest approach. Winter tires make a significant difference below 45°F, even without snow. |
|
Severe Winter Conditions (Alaska, Northern Canada) |
|
Look for the "Three-Peak Mountain Snowflake" symbol for severe snow service rating. |
Driving Style Assessment
Your driving habits significantly impact which tire characteristics should be prioritized. Answer these questions to determine your driving profile:
1. How would you describe your driving style?
2. What's your priority in tire performance?
3. What type of roads do you primarily drive on?
When to Replace Your Tires
Even the best tires eventually wear out. Knowing when to replace them is crucial for safety. Here are the key indicators that it's time for new tires:
Tread Depth
The legal minimum tread depth in most states is 2/32" (1.6mm), but consider replacement at 4/32" for all-season tires and 5/32" for winter tires.
The Penny Test:
Insert a penny into the tread groove with Lincoln's head upside down. If you can see the top of Lincoln's head, your tread is too worn.
Visual Indicators
- Tread Wear Indicators: Raised bars in the tread grooves that become flush with the tread when worn to 2/32"
- Sidewall Damage: Cracks, bulges, or cuts in the sidewall require immediate replacement
- Uneven Wear: May indicate alignment or suspension issues
- Age: Replace tires over 6 years old regardless of tread depth
Performance Changes
- Increased stopping distances
- Poor traction in wet conditions
- Excessive vibration or noise
- Vehicle pulling to one side
- Reduced fuel efficiency
Replacement Timing
- Seasonal Changes: Best time to inspect and replace if needed
- Before Long Trips: Ensure tires are in good condition
- After Damage: Replace immediately if you hit a pothole or curb hard
- Age-Based: Consider replacement at 6 years regardless of appearance
Safety Warning
Never delay tire replacement if safety issues are present. Sidewall damage, bulges, or significant tread wear can lead to blowouts and accidents. When in doubt, have a professional inspect your tires.
Tire Wear Patterns and What They Mean
| Wear Pattern | Likely Cause | Solution |
|---|---|---|
|
Center Wear Excessive wear down the center of the tread |
Overinflation - too much pressure pushing the center of the tire onto the road | Adjust tire pressure to manufacturer's specifications |
|
Edge Wear Wear along both outer edges |
Underinflation - too little pressure causing edges to bear the load | Inflate to proper pressure and check regularly |
|
One-Sided Wear Wear on just one edge |
Alignment issues - typically camber or toe problems | Get wheel alignment service |
|
Cupping/Scalloping Diagonal "cups" or dips around the tread |
Suspension problems, worn shocks/struts, or balance issues | Inspect and repair suspension, balance tires |
|
Feathering Tread blocks worn smooth on one side, sharp on the other |
Toe alignment issues | Correct toe alignment setting |
Common Tire Buying Mistakes
Avoid these frequent pitfalls when purchasing new tires:
Choosing Based on Price Alone
The cheapest tires rarely offer the best value. They typically wear faster and may compromise safety and performance.
Better Approach:
Consider the total cost of ownership, including tread life, fuel efficiency, and performance benefits.
Ignoring Load Ratings
Using tires with insufficient load capacity for your vehicle, especially when towing or hauling, is dangerous.
Better Approach:
Always match or exceed the load rating specified by your vehicle manufacturer.
Mixing Tire Types
Using different tire models or types on the same vehicle can cause handling problems and uneven wear.
Better Approach:
Replace tires in complete sets when possible. At minimum, keep the same model on each axle.
Incorrect Sizing
Deviating from manufacturer-recommended tire sizes can affect speedometer accuracy, handling, and safety systems.
Better Approach:
Stick to the sizes listed in your owner's manual or driver's door jamb sticker.
