Hi, I am buying a set of rims and snows for my 2009 E350 4matic and for my wife's GLK350 4matic. Do I need to buy TPMS sensors with them (the cars have TPMS)? If so, after install, do the cars recognize the new sensors or do I have to somehow register the new sensors?

Thanks,

Matt

 

you dont ned them. but you can install if you want to. youll get a light on if you dont have them but like i said its not necesary to have them
