14in tires???

a 26" diameter tire with a 3.91 ratio is the same as a 28 diameter with a 4.30 ratio. I know cause I ca;lculated the numbers and bought 26" diameter slicks for my car so I could use my 3.91 gears at the track effectively.

I ran a 3.91 in my barracuda and went back to the 3.23's after a few weeks.

I would recommend going with 15" tiresm then you can get even taller tires like 28 or 29" which could make that 4.10 gear "streetable".
