Concerning the vibrating/grinding noise. I have that and is WAY louder when I put my heaviest set of wheels on...chrome 20's with 265/50's as compared to my 265/75-16. It bothers me...its only when coasting at about 40mph or so. But it has ALWAYS been there!
It feels great to finally get it off the road full time. I still drive it, just not deliver in it as much now or actually at all so far. That is until the winter. With a car topper promoting my cousin's pizza place it sure did spark alot of attention locally. Before this I lived about 50 minutes away from work...then on the ride home it was about 1.5 hours due to bridge traffic. Its been a tough last couple of years for it. I do believe it is burning less oil now as compared to the past. I switched to regular 5/30.
