First post here; in fact, I created my account to ask this (and since I own a 2016 Three). Last week, I got unlucky and picked up a nail in my left front tire that couldn’t be repaired. One $575 tire bill later (and after a bit of discussion with an America’s Tire salesman, alongside a tiny bit of research on here), I put a set of Michelin Defenders on the car. I’m noticing a significant drop in MPG; whereas I could get 53-56 on a tank, now I’m averaging 45-48, with 50 if I’m doing a ton of surface street driving. On top of that, the engine and hybrid system seems to be working more and harder. I drive in Sacramento, no snowy weather driving, 70/30 split between freeway and surface street driving (I drive Uber full time). 70-80,000 miles a year. So, my question is, did I buy the right tire? I had planned on buying a set of Ecopia 422+’s, but was sorta led into the Defenders.
