What Causes Higher Front Wheel Temperature Compared to Rear Wheels?
2 Answers
The primary reason is that front wheels bear most of the braking force, leading to higher temperatures. Below are relevant introductions about tire pressure: 1. Service Life: Both overinflation and underinflation will shorten tire lifespan. Underinflation increases tire deformation and contact area, potentially causing sidewall cracks, excessive heat generation, rubber aging, and accelerated shoulder wear. 2. Increased Load: Overinflation excessively stretches tire cords, reduces elasticity, and increases vehicle load during operation. 3. Follow Recommended Values: Tire pressure should always match manufacturer recommendations. Reference values can be found in: vehicle user manuals, driver's door labels (near B-pillar), dashboard drawers, or fuel filler flap markings.
A few days ago, I touched the tires after a long drive and was startled to find the front wheels scorching hot while the rear ones were cool. It turns out this is primarily a braking system issue, as most vehicles concentrate braking force on the front wheels, causing the front brake pads and rotors to work more frequently and generate higher friction heat. Rear brakes are used less, hence their lower temperature. Especially in front-wheel-drive cars, the front wheels also handle steering and driving duties, bearing greater loads and thus heating up more easily. Additionally, uneven tire pressure or worn front wheel bearings can contribute to temperature discrepancies. I once neglected this, resulting in accelerated front tire wear—now I always check tire temperatures before long trips and address any issues promptly to avoid roadside troubles. Regularly inspecting brake pad thickness and tire pressure can prevent problems and ensure driving safety—small habits that make a big difference.
