Re: $30-35 worth of aero-mods and 25+ MPG!!!

Bug shields, when used as bug shields, are counter-productive to good aerodynamics and fuel consumption. So are sun visors I've bought trucks in the past that had both mounted. An '80 4x4 I bought in the early '90's had a sun visor. Thought it looked cool, but it made funny noises at speed, so off ...

Re: About 32mpg ...

My 1986 F150 originally was and still is fitted with 215/75 X 15 tires. If you do mount a smaller tire as the spare, this might cause problems if your differential is LS.

I, too, run @ [sidewall] maximum air pressure, but on the Michelin LTX M/S, that is only 35 PSI.
