In very hot weather, what tire practice is recommended?
- A.Let air out of hot tires to bring pressure down
- B.Check tire pressure about every 2 hours or 100 miles, and never bleed air from a hot tire
- C.Add extra air above the rating for safety
- D.Tires need no attention in heat
Correct answer
B. Check tire pressure about every 2 hours or 100 miles, and never bleed air from a hot tire
Why
Heat is a tire's enemy, and pressure rises as tires get hot, which is normal and must not be bled off. Frequent checks in extreme heat catch a tire that is running hot before it fails.
