I have considered that. I almost bought a set from the Classifieds on the DodgeTalk forum, but shipping was too expensive. They were OEM 17s and he weighed them at 28# each. Not as light as Centerlines, but certainly lighter than my 20s.

[edit] I've held off from pursuing 17" wheels because I am still looking to do a manual tranny swap. The factory 6-speed has a .78 top gear, and NV3500s (prior to the 6-sp) have a .73 top gear. The auto's top is .67, 4th is .75...and the truck doesn't do so great with the .75 on the highway. I've tried it a few times. I figure with 17" wheels the tires would be so short I'd regret it after the tranny swap. Typical size for my truck is 265/70R17, which is 31.6 inch diameter. My factory tires are 33 inch. With some math ratio MS Excel work, it looks like the 17s would make the engine turn another 100 rpms at 70 mph, with no other changes. But the .73 NV3500 5th adds another 170 rpm. Yuck.

All that said, I think she who must be obeyed is going to force my hand and make me buy new tires, and that means OEM size...
