Wheel weight

Hey guys, i’m losing my mind trying to find simple info.

Need the weight of the two wheels below.

Tacoma Wheel Alloy (OEM TRD OR)
42611-04160

TRD Beadlock Wheel
PTR18-35090

 

I've weighed the 3rd Gen OR wheel before. Since it was just a bathroom scale, it wasn't entirely accurate. I would say between 24-25 lbs.

As for the beadlocks, read somewhere around 29 lbs with the rings and bolts.

 

Yea that would make sense.
I’m pissed, can’t believe they are heavier. They are marketed as a lower weight option.
My fuel economy went from 12L/100km to 14L/100km.

 

You are losing your mind for no reason. If it is a Toyota Truck alloy wheel, Tacomas, 4Runners, FJ Cruisers, etc and it is less than 15 years old then the weight will be between 25-30 lbs. Most are 26-29 lbs. 3lbs of unsprung weight is not going to change anything with respect to efficiency or acceleration in the Tacoma application.

The big deal is the wildly different weights of tires of the same size. You can get a 30 lb tire or a 50 lb tire, depending on tire type and load rating.

 

The ONLY TIME unsprung weight is going to reduce your efficiency is if you drive 80% of your mileage in town on short trips. Highway miles will have no real effect. This is because of the constant acceleration of that mass from rest that local in town driving uses from stop and go movement.

If you lost efficiency, chances are something else changed, like your environment or your driving habits.

 

I agree. A few pounds will not drag your fuel mileage. Having lighter wheels will mostly affect acceleration due to the lighter mass to rotate.

Did you change tires at all? Can't remember exactly but the tires that came off the OR where around 36-37lbs

 

Perhaps! Although i’m seeing at least a 10% reduction in efficiency (initial observations)

Summer setup
Stock Goodyear Wrangler tires OEM
265/70R16
6lbs heavier.
TRD beadlock wheel (Bronze)
4-5lbs heavier.

My winter tire setup
Toyota OEM alloy wheels
4-5lbs lighter
Michelin XIce 2
265/70R16
6lbs lighter

Will keep you posted! I was easily getting 12L/100km combined. Pretty sure with heavier setup I will be around 14.

 

FYI TRD Sema wheel weight.

 

Love it when people say they will report back or keep posted. But never reply again for years....

 

A reply in a different thread counts I guess .

I have a manual and drive like a granny. However I have about 450lbs of crap in the bed (cap, drawer system)
I noticed with stock alloys and winter tires I was getting about 10% better economy. In other words... 8-10lbs more per tire had an effect.
Although when summer fuel comes out... it may balance out.
Go 55 MPH and listen to Bill Burr podcasts

 

Everybody blasting this guy for his
Comment.

You guys are all talking about unsprung mass when realistically it’s only a part of the equation. unsprung mass is anything such as suspension, wheels, tires, brakes etc. rotational mass or inertia is what comes into play. Anytime it takes the engine more work to turn somethings heavier mass like a driveshaft, brake rotors, wheels, tires = Rotating mass. If you shed lbs/kgs off these items the engine will have to work less to spin them, brakes work less to stop them.

Think of it this way - imagine the amount of energy you need to spin the front tire of your car/truck when it's jacked up and off the ground. Now think about the energy it takes to spin the tire on your ten speed bicycle. Big difference right? The ten speed wheel spins easier because it weighs less! -Yes, there are variances - friction in the bearings, etc., but the biggest reason for the difference is the mass (weight) of the wheel/tire itself. It's the engine that spins the wheels/tires of your truck.

if you engine is working harder you will burn more fuel. If a few lbs didn’t make a difference it wouldn’t be such a big upgrade in the racing world. So if you gained 5 lbs per tire, tires that’s 20 extra lbs the engine has to get moving, accelerate or stop.

Acceleration isn’t always going to be from a start. Even if you are going up a grade the engine will have to work harder with the change and it will be easier to spin a lighter mass.

is all of this going to equate to 2L/100km? I don’t know. But I’d say it sure would make a difference.

 

You'll lose more mileage if you have a full tank of gas compared to a tank with only 1/4 in it.

It's a truck, don't lose your mind over the small stuff.

 

Reading all your comments. Mine has black rhino ridge wheels 17” (33lb each)
and goodyear wrangler duratrak 265 70 r17 (44 each). My tacoma now has 2 mpg less on road (18) and highway 20 mpg.

Do you guys think it is too much weight for wheels?

 

My 35 ko2's are 65lbs each just for the tire. You'll be fine

 

But with that weight you have to do the regear. I don’t want to do that yet.
