Both would be exactly the SAME in 4th, since they both have 1:1 ratios in that gear.

Hi Wade:
Exactly. As mentioned in my previous post, I had to fudge the tire from 305 to 205 to get the "real world" number for my car. Why that is, I do not know. Nor do I know if a 205-50-15 vs a 305-50-15 has the same Outside Diameter.
Cheers
