Another good read. I've read over and over here, and all over Google about 17" vs 20", centrifugal force, unsprung, , tire load, yada yada... oh, my physics is rusty. I not defending either size, because I think they both look good.

So in theory, if you had a 20" rims (made of magnesium) that weighed the same as a 17" rims and the both tires had the same O.D. size and weighed the same, would it yield the same results?

Next, if I ran a set of 15" rims with LT tires would I increase my towing capacity?

Serious about the 15" rims. I know where I can pick up a set for cheap.


Sorry,

 

No 15s on a 3rd gen. No 16s either.

 

Are you saying I can't find an aftermarket 15 or 16 inch 5 on 5.5 set of rims with the correct load rating for the 3rd gen ? Confused about your stated, please be specific. Bummer, if so.

 

15 and 16 inch rims will not fit

 

Just pick'en at you, but I think you missed the part about being specific. Please don't take it the wrong way.
Is it because of the offset or center hole?

 

They will not clear the calipers.

 

Yep, simply a matter of not being large enough to clear the stock brake parts...

 

Cool, thanks bro!

 

Hemi 20" wheels 3:92 gears. What's the best way to tow on a flat 1100 mile trip? In "tow/haul" mode or in "O/D off" mode?

 

Tow mode is just that - for towing. If simply turning OD off was all that was needed, they wouldnt need a tow mode button.
