LT305/70R17 Toyo Open Country R/T 121QFrom morning commutes to long weekends, the LT305 70R17 Toyo Open Country R T 121Q is built to make every mile count. Built by Toyo, the OPEN COUNTRY R T emphasizes balance: grip when you need it and comfort when you want it. Blackwall sidewall construction helps the tire resist routine wear while keeping the aesthetic understated and refined. Channels and sipes are arranged to promote consistent traction while reducing pattern noise inside the cabin.
