Tire/Gear/Performance Question

[RiverRat]

Ok, I have a 5.0/4R70W/1354 transer case with 4.56 gears and 32" tires. I need acceleration, good towing power and low crawl speed. Would there be a noticeable difference between 32 and 33 inch tires?

According to the chart its only a few mph but if anyone has some input I'd appreciat it.
Transmission Ratios:
4R70W 1st: 2.84 2nd: 1.55 3rd: 1 4th: 0.7


Tire Diameter 1: 32 inches
Rear Gear Ratio 1: 4.56:1

You won't notice much of a difference. 4.56 is great with 33s.
