ONYX RCR Michelin Pilot 2 Tires

Back in May, I posted about the Michelin Pilot 2 tires, and I wish I had paid closer attention to my own advice! My buddy reminded me about these tires recently, and I finally got a set. Let me just say-wow! These are the next best thing to full slicks.

These tires are a fantastic upgrade for the RCR, offering incredible performance without compromising fitment. If you’re looking to level up your ride, these are the way to go!

  • Maintaining the correct tire pressure is crucial, as both over-inflation and under-inflation can accelerate tread wear and reduce tire lifespan. To ensure optimal performance, keep both the front and rear tires inflated to 32 PSI on your ONYX RCR.
