There are two things that have always bothered me about GM cars and trucks. The “U” shaped wheel wells that make the openings seem too large for the fitted tires and the rear seat that look like there’* plenty of room, but is too low to provide good thigh support.
If you look at German and most Ford products, the wheel arches follow the contours of the wheels so that the gap around the tire is symmetrical and even. On many GM products, it’* the “round hole (tire) in the square peg”. Because of this, trying to “fill” the wheel well with a larger tire will never be totally successful visually. Case in point, a lot of car magazines complain that GM cars seem “under-tired”. The tires are fine; it’* the wheel wells that are oddly shaped.
Take the Pontiac Aztek (Please!). As misshapen as that vehicle is, I’ve always thought that the extended “U” shape of the wheel arches made it even uglier. Try to imagine the Aztek with rounded arches and I think the vehicle would be, well, less ugly…
When you look at the rear seat of full size GM vehicles, there appears to be acres of room. Yet when you sit back there, your butt is low to the floor, your knees are spayed in the air near your rib cage and there’* not much room for your feet under the front powered seats. I had a chance to sit in a friend’* Pontiac Vibe and adjusted the front seat to my 5’ 7” frame. I then sat in the back seat and was amazed to find that I had plenty of leg and foot room because I was sitting higher up from the floor. I had plenty of thigh support and was much more comfortable than sitting in the back of my Bonneville. Go figure…
