Hi Y'all;
I have another question. My truck is a 1993 F-150 I-6, manual transmission that has never had the "stock" rims or tires on it. When I bought it I had the aftermarket rims changed over to it. Since then I've been running 30.50 x 9.50's on the front and 31 x 10.50's on the back. I suspect it has cost me some fuel economy...duh huh right...lol. My question is "can the computer be reset to accommodate for this and if so, how does one do this?"...thanks.

Here's a thread on how to adjust your PSOM to read correctly. A computer reset won't do anything for that.

ETA: Would help if I added the thread right lol
