When I bought my 2001 CLK430 (used) the dealer had installed 2 new tires on the front. The fronts were Michelin Pilot Sports , and the rears were Pilot Sport SX, both Z rated.
The rear tires now need to be replaced but some tire dealers tell me I cannot put a different brand on the rears - to do so would cause handling problems.
Yet other tire dealers say it doesn't matter and will willingly sell and install other brand tires.
I would think that as long as I keep the correct sized tires and correct speed rated on the front and the correct sized tires and correct speed rated on the rear there should be no problem.
Any opinions? Who is correct? Do I need to buy 2 or 4 tires.
