Scouter Analysis

The Toyo Proxes RA1 is a solid choice for those who prioritize wet grip, with a score of 9 that exceeds the ultra-high-performance summer category average. Its handling and dry grip scores are respectable at 8, but they don't quite match the top performers in the segment. The tire's comfort and noise levels are on par with the category averages, making it a balanced option for those seeking performance without excessive harshness. Where the Proxes RA1 falls short is in treadwear. With a UTQG of 100 and no mileage warranty, it has a much shorter lifespan than competitors like the Michelin Pilot Sport 4S, which offers a treadwear warranty. This could be a significant factor for cost-conscious buyers who rack up high mileage. The dry grip, while decent, is not quite up to the level of the Pirelli P Zero (PZ4), which might be a consideration for track enthusiasts. Overall, if wet grip is your primary concern and you can accept the trade-off in treadwear, the Proxes RA1 is worth considering. However, if you need a longer-lasting tire or prioritize dry grip for track use, you might want to look at options like the Michelin Pilot Sport 4S or Pirelli P Zero (PZ4).
