Car is my ’86 300E. 156k on the clock. This used car came with about +2.75 tires on it. 225/65/15 I think. Tires rubbed all over the place. The wheel actually puled in the direction of a turn during parking lot maneuvers. They were lousy Falken Ziex, the worst tracking, sloppy tires I have ever experienced -- just sloppy pigs all around. (Certainly all that extra sidewall contributed to this, I know, so maybe the tires were not entirely to blame.)

Now I have the correct size on the car and all the negative tire issues are over with. I also noticed it upshifts MUCH more smoothly — correctly actually, instead of the abrupt way it did with the old tires. This includes powering up freeway on ramps with the pedal on the floor and shift button depressed all the way. Simply an amazing difference with the right size tires on the car. My question is, does this make sense? Can tire size affect the tran adjustment?
