In Austrian vehicle safety and driving technique, what is the effect of fitting wider tyres (Breitreifen) on a passenger vehicle in wet conditions?
Answer and explanation
Correct answer: C. Increased risk of early aquaplaning
- Step 1: Wide tires create a broader contact patch that must push aside more water, causing hydrodynamic lift and aquaplaning at lower speeds than narrower tyres. Answer: Increased risk of early aquaplaning. Why not the others: Complete prevention of aquaplaning at any highway speed, Shorter braking distance on deep standing puddles and Lower rolling resistance and reduced fuel consumption do not reflect Austrian technical safety guidelines.
