🔧 Tire Comparison Calculator — Global Standards
“Tire comparison calculator” helps drivers, fleet managers, and tire enthusiasts compare two tires side‑by‑side using standardized metrics (UTQG, Load Index, Speed Rating, etc.). This advanced tool integrates global regulations (USA, EU, Asia) and visualizes differences with an interactive bar graph. Evaluate treadwear longevity, wet braking (traction), heat resistance, load capacity & speed potential. Make data‑driven tire choices worldwide.
🚗 TIRE A
⚖️ Load capacity: —
🏁 Max speed: —
Higher = longer lasting (relative to baseline 100)
🚙 TIRE B
⚖️ Load capacity: —
🏁 Max speed: —
Higher = longer theoretical wear

🔢 Treadwear (UTQG)
USA: Grade reflects wear relative to baseline 100. 500 = 5x longer than control. Worldwide many markets use similar ECE/ISO. Higher = longer life potential.

💧 Traction (AA/A/B)
USA standardized wet braking test. AA = shortest stopping distance on wet concrete/asphalt. EU uses A‑G label but similar philosophy. AA recommended for rainy regions.

🌡️ Temperature Resistance (A/B/C)
Resistance to heat buildup at high speeds. Grade A = highest safety margin. Critical for high‑speed driving, desert climates. Mandated by US DOT.

⚙️ Load Index (LI)
Numerical code = maximum weight per tire. e.g., 98 = 750kg (1653 lbs) global standard (ISO). Always match or exceed OEM recommendations. Crucial for safety worldwide.

🏁 Speed Rating
Maximum service speed. H=210 km/h, V=240 km/h, W=270 km/h. European/Asian regulations align with US speed symbol system. Higher rating = better handling at speed.
