Offset should be 10-20mm depending on the rim style and width. Ask the rim guy. You need to avoid the calipers. I needed to use 10mm on mine to avoid the calipers.kerien said:Getting a set of rims. Can someone help me with the correct offset for the 2004 Armada? I dont want to mess this up. Also if the rims are 20"s then what would be a good tire size to keep a soft ride?
Thanks for helping this newbee.......
As for tires, 305-50-20 is good and so is 305-55-20. I have the second.
The first is slightly shorter than stock. The second, slightly taller. My tires were large enough to need to have some of the inner tire well flexed with a heat gun to avoid excess rubbing. The height is only part of the rubbing issue. Width plays just as important a role. The tires rub at half turn, where the outer edge sticks straight back. Width pushes out the edge as much as height.
As for comfy ride, Mine is as soft a ride as stock, handles better, as quiet as stock, and has dramatically more traction. The only loss is a slight amount of acceleration, which you will loose whenever you increase the rim and/or tire size.
