Thumbs up Welcome Ernie

I'm always glad to see another TDI on Ecomodder. I wonder when one of us is going to get really brave and Basjoos a VW to see what the diesel can really do when optimized for aero with the right gearing.

I do have to side with ConnClark on tire wear. I have been running higher-than-suggested-on-the-sidewall tire pressures for decades. Up to a point you get better treadwear because you don't scrub off the shoulders as much when cornering, especially in a front wheel drive car. However, if you are doing a lot of straight line driving, the belts will bulge from the pressure and the middle wears faster.
