About 2 years ago, I purchased 2 new tires for my van (2007 Ford E350) and immediately started noticing that my front end kind of felt like it was swerving. I rotated the tires to the rear and it felt like the back end had to “catch” up whenever I move the steering wheel a little…this is always evident at highway speeds…not so much in town. My mechanic convinced me that the tires were the problem and I bought 2 new Michelins for the front (keeping the “bad tires” on the rear).
Well, the tires wore out and I just purchased 4 new Michelins (225/75 16 E-rated tires). I left the shop and headed down the highway and the swerving was greatly exaggerated.
Is this due to the new tires having a deep tread ? This seems very unsafe. When I change lanes, it feels like the van has to catch up to my steering. Even going straight it is hard to not feel the swerve effect trying to stay in a lane. Will this go away as the tires break in?
Any help would be appreciated.
