Stock TRD Off-Road wheel/tire weight

If anyone was wondering, it's just under 66lbs combined per tire. Shipped my old stock setup out today. Was digging for the information a few months ago and couldn't find it.

 

Perfect just what I was looking for!!

 

I love you haha, was just digging for that exact info!

 

Why is this important? Were you trying to estimate shipping costs? If so, why didn't you simply weigh them?

 

I was trying to use that number as a base line when shopping for aftermarket wheels and tires. My new setup weights 79.8lbs

 

When I saw switching up my setup, I saw quite the increase in MPG, but more piece of mind on the trails.

Stock tire and rim 2023 TRD Offroad
265/70r16 Wrangler kevlar 37.5lbs
Trd OR rim 24.2lbs
= 61.7lbs

My new setup is

265 70r17 wildpeak E, 52.9lb
Black Rhino Aliso 17x8 et0 22lb
= 74.9lbs

 

The "equivalent mass" of a tire/wheel is approximately 2:1. In other words, in terms of translational inertia, adding 1 pound to a tire is equivalent to adding 2 pounds to the frame. Therefore, your new tires and wheels added approximately the same as 64 pounds to your frame.

(74 lbs - 66 lbs) * 4 tires * 2 = 64 lbs.

I don't think anyone could notice the difference.

On the other hand, tires have rolling resistance. When a tire rolls on the ground, it deforms, and this deformation resists forward motion and causes the tire to heat up. Tires have varying amounts of rolling resistance. Things like size, thickness, rubber compound, tread design, and other things affect a tire's rolling resistance. Weight does not affect rolling resistance significantly, however a heavier tire likely has more rubber and thus more rolling resistance.

 

I mean I have bumpers, rock sliders, rtt ets. But I can really feel heavier tires. All I know is
Sprung weight= ehhhh
Unsprung weight = bad bad bad

 

You aren't feeling the extra weight of the tires. You are feeling the extra rolling resistance of the tires.

EDIT: maybe I misunderstood what you are feeling. Are you feeling a decrease in acceleration or a decrease in suspension performance?

 

I can 100% notice the difference. But I'm okay with it. I upgraded to be able to air down lower and have better puncture resistance.

 

See above.

 

Another way to say it is that, while there is likely a correlation between tire weight and rolling resistance, there is no causal relationship.

---just drive it----

 

I resemble that remark.

I'm trying to debunk misinformation that is leading these poor people to obsess on a few pounds of tire weight instead of "just driving it".

 

What misinformation? All we were saying is that we can feel quite a difference in drivability with our new setups.

 

I think I will have another cold one

 

The misinformation is the commonly repeated claim that tire/wheel weight is a very important criteria because tires rotate and thus have a larger effect on vehicle performance than non-rotating weight. Or more generally the claim that tire weight is one of if not the the most important criteria when choosing a tire/wheel.

I'm not saying anyone in this thread made any such claims, but I suspect that such claims lead to people obsessing on tire/wheel weight above all other tire/wheel qualities.

 

I've upsized twice now. No regrats!!!

 

lol I was just wondering this off hand (not enough to research) this morning on my way to work now that I have a tracking number for my new wheels and tires

 

Post some pics when you get them installed! Excited for you+
