Don---I can relate to what you are saying. Its not so bad with my roadster pickup, as it is pretty well stock height except for the drop given by a 4" dropped axle.---But---the 27 T I built 12 years ago was very low, and channeled 4". It was very disconcerting to be driving on a 4 or 6 lane highway, and be passed by transport trucks with tires taller than my entire car. I just about got scared to death on highway 400 north out of Toronto. A big freightliner was passing me, and just as the rear of the truck drew parallel to me, the inside dual shed its tread!!! It made one Hell of a bang, and then began to disintigrate right beside me. There were peices of rubber flying everywhere, at 70 MPH and about 36" from the side of my head!!! The only thing that saved me was the fact that it was the inside dual that blew, and the outside dual was between me and the tire that was flying apart. Man, Talk about change your underwear time!!!----It gets better---Next time I made that trip, I stuck to secondery 2 lane highways---to be safe, ya know---and damned if I didn't blow through a radar trap at 17 MPH over the speed limit!!
