Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Dunlop RoadSmart III is highly regarded as a durable, high-performance sport-touring tire that excels in longevity without sacrificing significant grip. Users consistently praise its stability and confidence-inspiring handling across a variety of motorcycles, particularly heavy touring bikes and sportbikes used for long-distance travel.
Pros
- Exceptional tread life and mileage compared to dedicated sport tires.
- Sharp, responsive steering and handling characteristics.
- Consistent and reliable grip in both dry and wet road conditions.
- Stable performance under heavy loads, including luggage and pillion passengers.
Cons
- Occasional reports of rear-end slippage during aggressive cornering with power input.
- Front tire wear can be uneven or faster than expected depending on suspension setup.
- Some users noted a firm ride quality due to the stiff carcass construction.
Observations
- BMW K1600GTL owners report the tire is an excellent match for the bike's weight and touring demands.
- Sportbike riders (e.g., GSXR1000) appreciate the tire as a long-lasting alternative to pure sport rubber without losing agility.
- The stiff carcass design is noted to sharpen steering response, which is particularly beneficial for heavier touring motorcycles.
The Michelin Power 5 is widely regarded as a high-performing street sport tire that excels in rapid warm-up, wet-weather confidence, and agile handling. While most riders praise its real-world versatility and grip, opinions on longevity and high-lean-angle stability are polarized, with some users preferring competitors like the Bridgestone S22 for track-oriented or aggressive riding.
Pros
- Exceptional wet-weather grip and stability in standing water
- Rapid warm-up times, even in cooler ambient temperatures
- Agile handling and predictable cornering behavior on public roads
- Strong confidence-inspiring feedback during braking
Cons
- Tendency for the rear tire to square off prematurely
- Inconsistent performance and grip degradation as the tire reaches the end of its life
- Lack of confidence at maximum lean angles compared to dedicated track tires
- Mixed reports on overall mileage, with some users experiencing rapid wear under heavy engine braking
Observations
- Users on middleweight naked bikes like the KTM Duke 790 report excellent synergy and traction control performance.
- Riders with high-torque bikes featuring strong engine braking noted a 'sketchy' front-end feel and accelerated rear tire wear.
- Mileage reports vary significantly, ranging from 2,500 miles to over 8,000 miles depending on riding style and bike weight.

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
