The tire size for Your 2011 Hyundai Sonata is 225/45r18. It has a wheel size of 18 inches. The recommended tire pressure iS35 psi. Your tire air pressure should be checked once a month using the same tire gauge. Low tire pressure can be dangerous and could cause a blowout. If Your tire-pressure warning light comes on, don't ignore it. You could be getting a flat. Low pressure could result from a leak or simply from the tendency of a tire to lose pressure over time. When air pressure gets too low, the tire's sidewalls flex more, and heat builds up within the tire.
