235/50/R20. Found driver side rear tire completely flat in personal garage yesterday morning and passenger front tire had low psi warning on as well. Used the fix-a-flat kit that came with my car to fill driver rear and able to get to shop. Car/tires have 5000 miles on them. Tire shop could not find anything wrong with the driver rear tire but stated a puncture was found in passenger front tire well and did patch that. I see this has been reported before on a Toyota Bz4x same year and same tire with mileage the same as well. I am concerned this could be an issue going forward and am scared to drive this car now any distance especially since there is no spare and I have to purchase a replacement cylinder for the fix-flat.
