Insight lurker here. Got over 800 miles on my second tank! I do top off but I don't bounce the rear end up and down to get every last drop in.
Riding solo for most of the tank without a passenger seat/glove box/rear wiper and 55psi in the tires. The fronts are RE92s but the rears are some brand in the 165/65/14 size I've never heard of. 230lb driver D:, drove the last 80 miles around the city/some 70mph highway with my 300lb friend. I didn't know they said 400lb max capacity before I bought the car. Good thing the tank was near empty!
I already bought and painted the plug to delete the rear wiper motor, I think I'll leave the interior panel off too.
