The RC300 is a variant of Lexus’s RC (Radical Coupe) line that features a turbocharged 2.5L 4-cyl mated to a CVT transmission, and is available with optional AWD. Bridgestone Turanza EL450, Bridgestone Potenza RE050A, Bridgestone Potenza S001L or Michelin Primacy Tour A/S tires would be OEM for this make/model.
When it’s time to shop 2021 Lexus RC300 tires, remember that this make/model is designed for an offset fitment, with different tire sizes in front and rear. We think you’d be most satisfied with premium summer/ultra-high-performance tires like the Kumho Ecsta PS91, Falken Azenis FK460 A/S or Firestone Firehawk Indy 500. Just be mindful that summer/UHP tires use a softer, stickier tread formulation that will stiffen up and lose traction on colder days. Summer/UHP tires shouldn’t be used when temperatures are below 40-45 degrees F. In that case, we’d suggest all-season tires like the Continental ExtremeContact DWS06 Plus.
