I've searched and not found any comments about this. Hoosier R compound tires are known for their relative fragility with on- or off-track hazards. I'm curious whether other R compounds, especially the A055, share that trait or are they sturdier in that respect? Thanks for your experience or research results.
A055 carries the same "Not for highway use" safety warning as R7. That says to me that puncture resistance is similar.
Specifically:
WARNING: DOT labeled Yokohama ADVAN A055 tires meet Department of Transportation requirements for marking and performance only and are NOT INTENDED FOR HIGHWAY USE. It is unsafe to operate the Yokohama ADVAN A055 tire on public roads. The prohibited use of Yokohama ADVAN A055 tires on public roadways may result in loss of traction, unexpected loss of vehicle control, or sudden loss of tire pressure, resulting in a vehicle crash and possible injury or death.
What problem are you trying to solve?
If you want something similar in pace that is legit streetable, consider Supercar 3R or TrackAttack Pro.
I can only add that I've done a lot of street driving on pretty awful roads with Maxxis RC1s and they held up well.
Edit: I should add that they were take-offs from rallycross at a track that probably would've broken my car in half if I did a full-speed lap, so that's another endorsement of their toughness.
Hm. RC1s are super heavy compared to Hoosiers (very light!), so I'd expect them to be much sturdier. In actual use I've seen much higher failure rates due to damage on RC1s (2 tires out of 6 sets that I've owned) than I have with R7s (1 tire out of way more sets than that).
Pretty sure that falls in the "anecdote" category rather than "data" though.
I've run most of the common r-compound tires and don't find Hoosiers more fragile than any other. They're all about the same in terms of durability.
What I like about Hoosiers is they wear pretty evenly across the tread. Whenever I've tried Toyos I've gotten weird and uneven tread wear. As for Yokohamas, they're so expensive you might as well run Hoosiers.
