Lightweight Rim 17 or 18s

[Semiihcircle]

Has anyone optimized a rim and tire combo to minimize weight? I am looking for A/T tire like KO3s or AT4Ws or something of that nature. i know its a bit counter-intuitive to ask.

lol got a nail in my tire so....................................

There is at least one driver on this forum that put OEM tires on sub-20 lb forged Volk Racing rims for maximum lightness and minimum rolling resistance. Going a step further could be putting pizza cutter skinny tires on forged 17" rims. My choice would be the ADVAN GT Heavy Duty, but others might like the Volk Racing TE37SB for the lightest possible.

A topic that has been discussed ad nauseum in this forum. Really depends on your definition of "optimize," and whether initial cost of entry is weighed against realized gains at the pump. @Markarian421 has done some amazing work detailing weights/specs of popular offerings, most commendably OEM reference points here: tire-and-a-few-wheel-options-spreadsheet Scroll to the last page for the most recent iteration of said spreadsheet and start there. It's not hard to shave a few pounds on each corner, but I agree that Volk would probably be the most significant wheel shaving, and likely among the most expensive.

Driving a 6000lb vehicle with the aerodynamics of a brick and worrying about fuel economy or the rolling resistance of the wheels is hilarious.

My goal is to minimize gained rotational mass and un-sprung weight. So im trying to go lightweight rims to make up for heavier tires.

Sure i can go buy whatever at whatever weight and have million pound wheels but thats not the goal.

It was more of a rhetorical question to imply that my guidance was going to be generalistic in nature. The link I shared is still valuable for researching.

Have you checked into Road Hazard Warranty protection ? Should 2 years unlesss you bought upgrade ... could be more.

I have Titan 7 ATK1 forged wheels in 18x8.5 with Yokohama 275-70-18 AT4 tires in standard load. This setup weights about 2lbs more per wheel than my stock 18” wheels with 265/70/18 per. Titan wheels are about 25 lbs each I believe

yea well.. that's just like your opinion, man

Many reasons to be concerned, one for instance...the difference between 28mpgs and >18mpgs

I went with a japanese brand 18" wheel @ 26lbs each. im still on OEM Michelin XTL (getting my moneys worth)
stop/go city driving 19.8 mpg
@85=19-22mpg
@75=22-25mpg
@65=25-27mpg
@55=27-32mpg
I've hit 36Mpg driving on Highway 101 during non stop commute traffic averaging >40mph

The stock 18" wheels are light @ 28lbs compared to most aftermarket wheels averaging 34+Lbs (including Methods)

Rotational mass or moment of inertia, scales with the square of the radius, which is exactly why lightweight rims are mostly hype for this specific claim.

Shave 4kg off a rim (150mm radius) and you save 3.7% of total moment of inertia. Remove the same 4kg off the tire (365mm radius) and you save 22%. Same mass, but the reduction of the moment of inertia is 6x more effective on tire, purely because the mass sits farther from the axis and I scales with the square of the radius.


Alloy rims still win on unsprung mass, suspension response, and ride quality, so if you're racing, that trade-off still makes sense.

I don’t think I’ve ever even considered this, yet it makes complete sense now that you say it. Saving this to reference later!

Have some TE37's if you want lightweight wheels. PM for more info.

Increasing the moment of inertia of an already not-so-fun car just hurts the handling further

True, but I didn't buy this vehicle (a tall brick) to take to the track.

Having owned a lifted Land Rover Discovery for almost 20 years (11mpg on premium gas!), I learned to accept this type of vehicle for what it is, and not try to make it what it isn't. People worrying about things like rolling resistance or mpg after putting more weight on the truck (bigger tires, racks, bumpers, winches, gear) just seems silly to me.

If one wants a high MPG car, buy a Prius; want a track car, buy a Audi/BMW.

I bought this vehicle for reliability (it's a Toyota), the center/rear locker, it being a body on frame vehicle, and having a pile of torque (...and it reminds me of my old Disco). I'm accepting that I'm not going to get awesome gas mileage, or that I can't take corners at 60mph.

The ModCo M71 and M72 are the lightest we sell by a decent margin--even lighter than the Volk TE37XT. Of the tires we sell, the Nitto Terra Grappler G3 is usually the lightest by a small margin, assuming the competition also comes in a P metric.

 

[Semiihcircle]

I ended up going with TE37XT 18x9 +15 with 275/70R18 Toyo Open country AT III EV 44/45 lbs/tire. I did not weigh the rims solo or combined weight. Pictures to follow.
I think im equal in weight to OEM wheel/tire setup. maybe minus a pound or two.

TE37XT in 17x8.5” weighed in at around 19 pounds, 18” around 21 according to Showstoppers USA measurements;

Spoiler Alert
Most Toyota owners who drive offroad are usually concerned with the following:

• Range/MPG
• CV axle longevity
• Transmission, Transfer Case, Engine Temps
• Power/Torque

Hence the reason for properly setting up their vehicles with light weight wheels
