Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Sumitomo H/TR Z III is widely regarded as a high-value performance tire that offers a compelling balance of dry grip, comfort, and affordability. While it is frequently praised as a cost-effective alternative to premium brands for daily driving and spirited street use, some users note limitations in extreme wet-weather cornering and high-horsepower traction.
The Toyo Proxes Sport is a polarizing budget-oriented performance tire that offers strong value for daily driving but receives mixed feedback regarding its consistency. While many users praise its dry grip and comfort levels, a significant portion of owners report rapid tread wear and unpredictable performance in wet conditions, particularly on high-performance vehicles.
From Reddit, forums and review threads. Not part of our score
We haven't collected enough community discussion about this tire yet.
Community opinion on the Toyo Proxes Sport line (including Sport 2 and A/S variants) is largely positive, praised for great value, quiet ride, and solid performance. However, some users note a lack of long-term reviews for newer iterations like the Sport 2, and others seek specific fitment details like load ratings and efficiency impacts.
“Toyo Proxes Sport 2 Really enjoyed these Proxes Sport 2s on my Alpina over the last year - in fact they’re so good I’ve put them on the B3 too! Great value for money. Read more”
“I have real world experience with the Toyo Proxes Sport AS+. This may be the best all around tire on the planet IMO. I'm old and so I've tried multiple tires in real world conditions as a daily driver with performance in mind. I know every Michelin and Pirelli. I've become an expert on available tires in the USA.. What you will find with This tire: * They are immediately quiet *Resist hydroplaning in big water * Higher than expected dry performance in super hot weather for an AS * Maintain tread pattern to the death and remain quiet. These tires are next level.”

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.
