Tires: 2005 STS Cadillac, tire placard, 2005 cadillac sts

Question
I realize that I have two different size tires on my 2005 Cadillac STS front wheel drive.My question is should the front tires be larger than the rear. My vehicle is higher in the rear.I just replaced the front bumper due to dragging on my entering and leaving my drive way.
Thanks, Lou

Answer
Lou,

Let's start with the basics:

On every vehicle sold in the US, there is a sticker – commonly called the tire placard - that lists the original tire size and the proper pressure for that size.  The placard is usually located on a doorpost or in the glove box – but sometimes it is located in the trunk or on the fuel filler door.

BTW, it doesn't matter who makes the tire or what pressure is listed on the tire's sidewall, if the tire size is the same as the placard, then the pressure listed on placard is also appropriate.

I'll bet your vehicle tire placard says to put the larger tires on the rear - and you should follow that!
