Michelim Energy LX4 tires were OEM's when I bought the Hyundai Van brand new and even after going through 9 different tires that were attempted to be balanced by every means available at multiple tire places these tires absolutely would not hold balance. I put up with them for almost 50,000 miserable miles of mostly Interstate driving and vowed NEVER to buy another Michelim again. I had read good reviews about Goodyear Assurance Max All-Weather tires, so especially because I live in snowy Northern Indiana, I rolled the dice and have been COMPLETELY satisfied with my Goodyear buying decision. After over 40000 miles there's between half and three-quarters tread left on the four tires (I'm not good at routine rotation or they'd probably be even better)and these tires still perform like when new. I'm not sure what the mileage savings is for the Fuel-Max part, but I average around 20 MPG divided between city and highway driving, and have gotten almost 27 MPG for 100% Interstate driving at around 70 MPH. I think that's pretty good for a 4500 pound 7 passenger vehicle with a V-6 engine and every luxury option that Hyundai offered in 2007. I would buy another set of these Goodyear's in a heartbeat!
