Here's a set of tables built for the different gearing/tire options we have on our FJ's. Take a look:

You can see with your stock gearing and stock tire size, you are in the ballpark with your mph vs rpm.

Do you think it was the weight, the aerodynamics, or all those punches to your kidneys causing the slowdown? :-)
Is her name really, "Crap" ?
Even so, there are supposed to be 'other' benefits.

I might encourage you to check your indicated speed with a GPS. Don't be surprised if your 10mph slower than the GPS speed.
