Was wondering if someone with a 235 AD truck/T5 could recommend a ring/pinion ratio that would keep my RPM's in the correct range.

My engine is stock, T5 has a .72 OD, tire height will be between 28-30". I have a choice of 3.08, 3.42, 3.73. Most driving will be on flat land@ 65 mph.

I've done all the RPM calculations but would like to hear from someone who actually drives this, or a similar combo.

In other words, what RPM's in OD would keep my 235 happy without having to shift into 4th at the slightest incline?

Thanks in advance, Dave
