Description

🇯🇵 Dunlop GrandTrek PT5 (235/55R18 100V JP Y24)

“The Science of Stability.” The 2026 Choice for Refined SUV Performance.

The PT5 was engineered as the direct successor to the PT3, focusing on solving the common “vehicle wander” and road-noise issues associated with tall SUVs. For 2026, it remains one of the most stable highway-terrain (HT) tyres on the market, offering a massive 12% improvement in steering stability over previous generations.

✨ Key Technical Features

• 🏎️ 12% Enhanced Steering Stability:

  The PT5 features a revised tread profile that creates an 8% larger contact area than the PT3. This wider footprint significantly suppresses “vehicle wander,” providing a much more planted and authoritative steering feel during lane changes on the PIE or ECP.

• 🔇 30% Narrower Shoulder Lug Grooves:

  To tackle pattern noise, Dunlop narrowed the shoulder grooves by 30%. This physically traps and reduces the amount of sound escaping from the tread, resulting in a remarkably quiet ride—making it one of the most silent SUV tyres in its class.

• 🌧️ Asymmetric Pattern for Wet Safety:

  The asymmetric tread design features “non-penetrating” grooves on the outer intermediate block. This reduces outward noise radiation while maintaining deep water-evacuation channels that provide Class-A/B wet braking performance during tropical monsoons.

• 🛏️ Vibration-Dampening Sidewall:

  The internal casing is designed to function as a cushion. It absorbs and disperses micro-vibrations from rougher asphalt, providing a smooth, cloud-like ride quality that complements the refined suspension of luxury Japanese SUVs.

• 🧪 Advanced High-Silica Compound:

  The rubber compound is rich in silica, which not only ensures superior grip on wet surfaces but also reduces rolling resistance. For hybrid owners, this translates to improved fuel efficiency without sacrificing the tyre’s high mileage durability.

📊 Performance Summary

• Steering Precision: ⭐⭐⭐⭐⭐ (Elite stability for SUVs)

• Road Noise: ⭐⭐⭐⭐⭐ (Class-leading noise suppression)

• Ride Comfort: ⭐⭐⭐⭐⭐ (Luxury “cushioned” sidewall tech)
