If you're shopping for an affordable grand touring all-season tire that handles everyday commuting without breaking the bank, the Sumitomo HTR A/S P03 deserves a close look. Priced around $122 for a 215/60R17 size, this tire promises a 65,000-mile treadwear warranty and focuses on comfort for urban drivers. In our hands-on testing, it earned an overall score of 6.8 out of 10—solid for the price but not a standout in performance categories.
We evaluated it across key metrics like braking, handling, comfort, noise, and efficiency using standardized tests on a variety of vehicles. While it excels in ride quality, longer braking distances and higher rolling resistance hold it back from top honors. Read on for detailed breakdowns, pros/cons, and tips to maximize its lifespan.

Here's how the HTR A/S P03 stacks up against average grand touring all-season tires based on our lab and real-road tests. Scores are out of 100 for easy comparison.
| Category | Sumitomo HTR A/S P03 | Average Competitor | Notes on HTR A/S P03 |
|---|---|---|---|
| Dry Braking | 62 | 75 | 60-ft stop from 60 mph: longest in test group |
| Wet Braking | 65 | 72 | Longer than average stops |
| Hydroplaning | 70 | 70 | Average resistance at highway speeds |
| Dry Handling | 68 | 76 | Slower figure-8 lap times |
| Wet Handling | 68 | 74 | Adequate but not agile in rain |
| Ride Comfort | 74 | 70 | Plush and forgiving on rough roads |
| Noise | 74 | 72 | Quiet at highway speeds |
| Rolling Resistance | 74 | 80 | Higher drag impacts MPG by ~1-2% |
| Projected Tread Life | 45,000 miles | 55,000 miles | Falls short of 65k warranty |
| Price (215/60R17) | $122 | $140 | Excellent value upfront |
This table highlights the tire's budget-friendly comfort edge but reveals safety trade-offs in braking and handling.
Safety starts with stopping power, and the HTR A/S P03 shows room for improvement. In dry conditions, it required the longest 60-foot stops from 60 mph among 13 tested tires—a full 5-7 feet more than leaders. Wet braking was similarly extended, averaging 3 feet beyond the category norm. Hydroplaning resistance hit average marks, holding steady up to 70 mph in standing water during our aquaplaning simulations.
Pro Tip: Pair this tire with precise pressure monitoring using the AstroAI Pencil Tire Pressure Gauge 2-Pack. Accurate PSI (10-75 range, ±2% accuracy) prevents uneven wear and improves wet grip.
On dry pavement, the HTR A/S P03 completed our figure-eight course in 28.2 seconds—slower than the 27.5-second average. Wet handling mirrored this at 29.1 seconds, feeling stable but unresponsive during quick lane changes. It's best suited for sedate highway cruising rather than spirited cornering.
Where it shines: ride comfort and noise suppression. Subjective road tests on pothole-ridden suburban streets scored it 74/100, absorbing bumps better than pricier rivals. Cabin noise stayed under 68 dB at 70 mph, ideal for long trips.
Rolling resistance at 74/100 means expect a slight fuel economy hit—about 1-2 MPG less than low-drag options. Our projected treadwear of 45,000 miles (UTQG 600 A A rating) suggests rotating every 6,000 miles to approach the warranty.
Pros:
Cons:
This tire fits budget-conscious drivers prioritizing comfort over sporty performance. Think minivans, family sedans, or daily commuters in mild climates. Avoid it if you drive in heavy rain, tow trailers, or prioritize fuel savings.

Our evaluations mimic real-world use: instrumented braking from 60 mph, figure-eight handling at 0.6g lateral acceleration, noise in a soundproof chamber, and tread wear via drum simulation (15,000 miles equivalent). We tested the 215/60R17 on a mid-size sedan over 500 miles of mixed roads.

To hit that 65,000-mile warranty:
For off-road adventures, consider the Pacific Cavern Mountain Bike paired with knobby tires.
Elevate your driving experience:
It comes with a 65,000-mile treadwear warranty, prorated based on verified wear. Road hazard coverage is included for 2/32" tread depth.
Common sizes include 215/60R17 96H (tested), plus 205/55R16, 225/50R17, and up to 245/45R18 for sedans and crossovers.
As a grand touring all-season, it's M+S rated for light snow but not a dedicated winter tire. Expect limited traction in deep slush.
Rolling resistance scores 74/100, leading to 1-2% lower MPG than premium low-drag tires. Proper inflation helps mitigate this.
Around $122 per tire online, making a set under $500. Shop sales for deals.
Final Verdict: The Sumitomo HTR A/S P03 delivers value-driven comfort for casual drivers but skips premium safety. Equip it right with our top picks above.
