IMO if you're going with oversized tires, the difference in wheel weight is negligible. 24 vs 27#s is almost a rounding error when your tire weight goes from 42 to 60# or more. Unless you're going to optimize tire weight as well I wouldn't bother as you're still going to notice a performance difference in overall unsprung weight.
I agree and I limited my choices too much.
You don't even really see much difference in fuel consumption all things considered and driven highway.
While i dont mind saving money on gas, range is something i dont want to compromise AT ALL.
Also, if you've got the bigger front brakes, you may as well just disregard weight (almost).
Given that AHC is present, you still don't want to overwhelm your shocks though even if it doesn't hurt to add some weight over stock.
I would be stoked to see some aftermarket ahc shocks come along. Or a rebuild/retool kit or something for them.
Tires are absolutely the ultimate factor like you said and if you have your brand of choice then the rest of the decisions are relatively easy.
Its finding the wheels that are a pain in the ass. Most here have either suboptimal offset or spacers. Both have issues depending who you ask.
Ideally my next setup would be an 18x9 +35 anything 30lbs or under on the 53 lb 275/70r18 toyo AT3.
(Or a Ridge Grappler / KO2 both of which are better looking designs than the toyo, both of which are 58 lbs.)
Bigger wheel, bigger tire, more optimal offset. Still right around the target weight to retain the normal damping rates of AHC.
I used to be super weary of LTs too until recently and now i wont hesitate to go to an E load. They are perfectly acceptable at the right pressures even for a comfort snob like me. If even one interior panel is shaking or rattling on bumps im not interested.
The LTs are not earth shatteringly, teeth jarringly stiff if you don't inflate them for a non existent load.
Another big OCD thing i have with tires is the sidewall integration. The KO2 looks like the only tire on the market which is molded with a truly integrated sidewall lug structure. Everything else has a mold delineating the tread and sidewall and looks off to me as if it were a two piece, (which they most likely are).
