Lightest possible 37'' Tire Combo

[Deola]

I think I figured a way to make 37s lighter than 35s on the same wheels I'm already running(aev saverge). Do away with the spare, mount a viar system under the hood( cheaper than a 37"tire), and keep a plug kit in the center console. I would also be able to drop an additional 39 lbs from my swing away spare tire carrier. I've never not run a spare, and the worst damage I've had to a tire was easily fixed with a plug. Another pro would be I could actually see out of my rear window before backing over a Prius. Haha. Also this would lower my COG.

I want your input on the above thought process. I'm also wondering if my aev 2.5 lift with flat flares and 37s will help or hurt my articulation off road vs the same lift with the current 35" tires
