HI, My 2010 had 28k miles on it with michelin Energy tires. Had to change them at 35k , decided to try michelin Primacy MxM4 , which I was told had better wear, handling and still had a good LRR rating. Now at 75k and looking to get another 10k. My gas milage does not seem to have suffered much if any . I get 38 around town and similiar on the highway. Road noise is no worse than before and ride seems good. I would like to hear other hybrid results to see if other brands have better results. I have heard of mpg 45 or higher by some users. In summer on flat roads The best I've done in a 400 mile fillup was 42. Thanks
