A lot more drag when driving trough water on the pavement too. I added wheel spacers to reduce the scrub radius, with out them the car didn't track as straight. The big tires have a lot more grip on hard cornering and I added a rear anti-sway bar. I didn't notice and increase in coasting distance from the 165/80R15 tires. The big tires are terrible in the snow and slush on the highway. Ice packs in around the wheel well, breaks off and rubs on the tire, not enough clearance.

This is exactly the point I was trying to get across in my posts.
