 Made a trip from Tacoma Wa to Reno Nevada last weekend for 3 days 720 miles 1 way averaged on trip about 38 mpg in lots of mountain terrain, got as much as 44.1 miles per gallon doing 65 in the flatlands, very impressive fuel economy and not lacking any power either. First thing I did after finding out the hard way, Side Wall Puncture" on right rear tire, was get rid of the junk Kumho tires and replacing with some decent Dunlops with more rigid sidewalls. d Then found a 4x100 pattern 16 inch wheel and put one of the stock Kumho tires on it for a spare. P.S it does fit in tire space in rear. Car does not come with a spare (Very Poor Idea Hyundai) Pump and fix a flat does not repair a sidewall
