Hello,
Got a new '04 Wrangler X in September. I plan to use this jeep for "fun" driving on-road in warm weather, occasional snow driving (on-road) and mild off-roading (no serious mudding, rocks or hill-climbing). It is not a daily driver.
The vehicle is a stock Wrangler X with I6 engine and 3.73 gears. The only mod is a set of 31" AT tires (Dayton Timberlines, not BFG) and black wheels with faux beadlock-looking attachments - obviously for appearance only.
I plan to gradually outfit this jeep with more trail-friendly gear, although I don't plan to lift it or use larger tires.
My only question at this time is about speedometer accuracy. When I took delivery, they made me wait for about 45 minutes while the salesguy said they were making an adjustment so the speedometer would read accurately with the (dealer-installed) 31" tires.
I happen to have a GPS, and, according to it, the speedometer reads slow by between 4 to 6 mph.
Is a GPS a good way of measuring speedometer accuracy? I'm not sure if the dealer just gave me a run-around, did something wrong, or if my GPS is just not an accurate device for measuring actual vehicle speed (I use it for geocaching, and it's been very accurate for that).
Thanks for any advice or comments. I enjoy reading this group.
