The sticker on my 2006 Beetle TDI says to put 35 lbs on the front tires and 39 on the rear. Am I reading this right? (I have the 205-55-16 tires. Sound odd to put so much more pressure on the back of the car, since the front, with the heavy TDI engine holds more weight. I inflated the tires to these level and the back rides like a rock. Full disclosure: I just bought this car and it came with rear tires that were scalloped/cupped on the inside thread. I wonder if overinflation causes them to bounce around and cup.
