I forgot to ask in my last post what the tire size is on these cars. 1996 VW Jetta Trek. If I put a penny in the tread, how high should it be compared to the penny?

What the heck are you talking about?

Tire size is printed on the door sticker. 2 or 3/32" of tread left is the minimum. I think on a penny inserted upside down that comes out you can see all of Lincoln's hair then it's time to replace the tire.

Thanks! What is the best brand of tire for this car for reliability and life?

I have been selling tires for 3 years best riding tire I have seen on a vw is either the Bridgestone Potenza G009 or the new WideTrack Fuzion HRi's
