Yeah - I used to have low profile tires with insanely hard sidewalls on my Civic.

The problem with that was one of the rims was cracked - and I didn't know it. It was leaking air, and I never used to check my tires except on fill ups, which were about every 2 weeks... so I could go up to a week without any air in a tire.. and never notice a difference. I never noticed an impact between fillups after I started monitoring it either... then I got the rim fixed, had it tested for leaks w/ the same tire on it, and started checking it every day when I put it on, I still didn't get an FE change.

Anyway - the point was, with low profile sidewalls, it's very difficult to tell without a gauge if you have a soft tire... they're never actually SOFT.
