with 4.10s and 26.4 in tire at 67mph i should be at 3457rpm which is a lil high but i can jsut drive the streets were i go and if i go to the track ill tow it maybe...
how much diff is there from 3.91 and 4.10 becasue i have a chance to get 4.10s for a good price
245 60 14s are the widest they make now for 14s. i work at a tire shop and was looking for some for myself. they arent a bad size. i've got some and could take some pictures to give you an idea on the size. but if you really want selection, go with 15s
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".
