Unfortunately, that is not the case. See the following link, where dodge spells it out.

As you can see, wheel size does indeed make a difference-a 1050 lb difference to be exact.

 

Exactly. That's b/c of the unsprung additional weight of the 20's.

So, my truck can tow 6,450 lbs. My estimate of 6,500 lbs was pretty dead on. And my truck with 3.92s can tow 7,450 lbs, so my estimate there was pretty spot on too.

The 4x4 only reduces towing capacity by about 250 lbs, so I was a little off there. A 4x4 Crew with 3.55s can tow 6,200 lbs and with the 3.92s it can tow 7,200 lbs.

Thanks for the link V8440. That settles everything.

 

Nitto came out with grapplers in 20's decision over your welcome :>.

 

I looked at some Nittos and Coopers side by side and I decided I liked the Coopers better - looked more aggressive and they were cheaper.

 

coopers over nitto's :O
