Hi I have a 2010 Mercedes e class rwd. It hasn’t been stock in years but I’ve been running 255/35/19 front and 275/35/19 rear. I recently went to 235/40/19 front and 285/35/19 rear. I love the ride so much better but I think it gave me a few weird shifts or maybe I imagined it. I was wondering if this is a large enough size to mess up the transmission of the car if I continue to drive with this setup. The wheel widths are 8.5 front and 9.5 rear if that helps.

    This only started once I put the larger tires on and it is very minimal. I’d probably be the only one to notice because I drive the car daily. The trans itself is pretty well maintained. I recently did a service on it. I have not done a relearn on it however is that required? I didn’t do it any of the other times I went up in size.
