Just got call from credit union, that they will not finance a car over teen years old, sold all the above is mute for now. I will definately look into tires/wheels being stock on any new vehicles we potentially purchase. Also interesting nobody in my area re calibrates speedometers anymore. I was really surprised by this. A local speed shop gave me an east bay area number who does, but they too said the economy dumping, caused them to let go of the mechanic who used to do this for them. Interesting! I did find some units on Summit you can buy for domestic cars that will recalculate and program your speedo base on tire diameter.
