Perhaps you are more sensitive to the ride than I am but I've never felt any kind of tire problem even when running my 54mm tires on 17mm rims. Certainly not like I'm "riding on jello". These are full on knobbies with aggressive off-road knobs and I'm not shy about cornering. I corner at the similar speeds on my road bike or mountain bike. I also have 37mm tires on 14mm wide Deep Vs and I'm not shy about hurtling down hills on a loaded touring bike either.
If the tire is going flat, I can feel the bike get a bit flaky but "flat" in this case means down around 20 to 25psi or lower. My normal pressure on knobs is around 45psi with a 200+(+

)lb load. My pressure on the touring bike is a more normal 100 psi with a 200+(++) load.
