I am about to get some new wheels and I am thinking of going with a smaller tire(275/45/20 Goodyear Eagle GT 2) This tire has a 3.25" difference in diameter from the stock 275/60s. Think it will be alright? Im not tire expert here...

If you are running 4.10 or 4.56 gears and dd it don't do it you rpm will be high if you have 3.92 or lower it would be ok for dd we run 28" slicks at the track and 108 at almost 6800 rpm in third so I would imagine with gear rpm would be up there stocks gears is bearable I would say

I run 28" tires with a 4:10 gear at 2100 @ 65mph. Not a problem...

I suspect you'll like it. The drop in size (diameter) will make it feel like you put a set of gears in it.

hmmm, I also switched to a 17" (265/70R17) winter tire from a stock 275/60R20 all season. Not sure what my gearing is but the overall difference in height is about 2" lower. Is my speedometer & odometer going to be out?

Yes your readout will be off; somewhere here on HTC a long time ago there was a great post showing a calculator that would immediately give you a reading for just about every tire & wheel diameter combination available - but I can't find it at the moment - maybe one of our techie guru's can retrieve it for you .

Smaller tires will fit better with the overall look of your lowered truck. You should check out some lowered trucks for their tire size.
