Stock Wheel Weight - FRS Release Series 2.0

[jkamelo]

UPDATE: I weighed them myself. They’re 16lbs.

—

I was shopping for new wheels when it occurred to me that my FRS Release Series 2.0 came with 17x7.5 forged TRDs. Although 7.5 is a bit narrow for my taste, I’m strongly considering just keeping my stockies, putting Pilot Sports on them, and calling it a day. I mean, I essentially already have free forged wheels.

That said, I don’t know how much my wheels weigh and I was wondering if anyone here did. Toyota’s website doesn’t say, and they aren’t in the Directory.

If not, no worries, I’ll have to weigh them myself. Figured I’d ask first.

yeah, just put some decent tires in 225/45/17 on.

i made a thread on the subject of wheel weight, people basically debunked it ."weight shouldnt really matter unless youre competing"

a relevant read to justify sticking with your trd wheels


typically, the guys running 255's on 17x9 are VERY experienced performance drivers who need the grip. not to assume too much about you, but if you're anything like me, 225's will suit you well.

Thanks for the thread and the advice. Assuming my wheels are ACTUALLY forged and are light enough, I think this is the way to go. But it’s good to know that weight isn’t a big deal since my car is just a daily.

Just to add another point of view, weight is not unimportant for daily driving. My bro got Motegi MR131 traklights for his 9th gen civic and despite being about two pounds heavier than RPF1s in the same size, the difference between the motegis and the OEM alloys was night and day. His first words were, "now I understand when people say the car feels light on its feet". Yeah, he won't be breaking any boy racer 30 roll records, but just driving around feels more pleasant with lighter wheels. Sometimes it's not about performance, but about feel.

That's why we drive twins and not mustangs.

Look at Firestone Indy FireHawks and GT Radial SX2's. Just trying to save you some money on rubber. I got tired of paying the Pilot Sport tax to be honest.

I have owned different sets of wheels+tires in the last 3 years for daily driving + weekend canyon runs:
stock 17x7 @ 20 lbs + 225/45
Enkei PF01 17x7.5 @ 16.75 lbs + 225/45
Enkei PF01 18x7.5 @ 17.5 lbs + 225/40
2019 TRD SE 18x7.5 @ 22 lbs + 225/40
Black TRD 18x7.5 @ 24 lbs +225/40

Now, I switch between the 18" TRD & the 18" Enkei's during winter & summer. The huge 6.5 lbs difference is definitely noticeable especially in accelerating as the heavy TRD's are more sluggish while the PF01's are very agile. Of course weight matters too in daily driving since everything adds up as you do more stops & go's which translates to putting more gas to make the wheel spin from standstill & on inclines while it takes more brake power to make the wheels stop. Weight is indeed negligible for dailies when you already have the momentum on relatively straight roads like the highway or faster roads.

I've recently gotten Motegi MR140 18x8.5 @ 19.7 lbs & will be installed in the spring. So, I can't comment on its handling yet being slightly heavier than the PF01 but still significantly lighter than the TRD's.

Wheel weight matters, A LOT! That is true for driving on public road, too.

I run 16-inch Volks Racing TE-37 (forged) that weighs 5.1 to 5.3kg, averaging at about 5.2kg. The reduction in wheel (unsprung) weight makes a huge difference in acceleration and response, ride quality, and handling. The super light lug nuts also save another 180 grammes per wheel.

I am running winter tyres on 16-inch OEM stock wheels now. The stock wheel weighs about 7.5kg, hence only about 2.3kg (about 5 lb) heavier than the TE-37. Even that slight weight difference is noticeable.

I am only running 205/55-16 tyres. I have yet to run out of traction on a public road. May be I am not driving irresponsibly enoug? At least they generate less road noise than 215 or 225 tyres, and ride better than ultra low profile tyres.

All I can say is that you don't know what you are missing until you try light weight wheels.

[Yoniyama]

The lightest 16-inch wheel available is the TWS T-66F (forged), at about 4.8 kg. (Yes, you can save 10lb per wheel.)

But if you go up to 17-inch, wheel weight goes up significantly. The TWS T-66F comes in at about 6.3kg, and Volks Racing (TE-37 and CE-28) goes up to almost 7kg. Almost everything else is 17lb and above. Spending about US$3,000 on a set of 17-inch wheels to save 6lb (each) seems very expensive.

I spent US$1,000 on a set of used 16-inch TE-37 and save almost 4kg per wheel, that seemed more economical to me. Oh, but I haven't told you about the 2-piece front brake rotor that saves 6lb per corner.

All I can say is that after you have shed more than 6.5 kg (unspring weight) per front corner, you will never go back to monster wheels.

Tire weight is actually more important than wheel weight, but both completely change how the car feels. I swap between enkei RPF1s and stock and the difference is extremely noticeable.

Could be shipping weight including all packaging...

That was it!

I finally weighed them myself. The wheel/tire combo was 38lbs. Tire rack told me that my tire was 22lbs in a 215/45/17, meaning the wheel is 16lbs. Might be forged after all...

[jflogerzi]

16 lbs is a good weight for a 17inch wheel. For normal driving slap some nice 225 or 235 sized rubber and your golden.

FWIW, I recently got some of the 17" TRD forged accessory wheels (same as the RS2.0, but gunmetal finish instead of black). I weighed one on a postal scale and, with two tries, the heaviest reading I got was just under 15lbs 3oz. That's with no center cap, valve stem/tpms, balancing weights. I was really pleasantly surprised. So forged and lighter than an RPF-1 for only slightly more money.

For full disclosure, my weighing method used a self-service kiosk at a post office. So as not to give away what I was doing or look like a total loon I weighed one wheel in its box as it came from the dealer and compared it against one empty box with all the associated foam and packaging that had been on the wheel. Full box weights were 19lbs 5.6oz & 19lbs 4.0oz. Empty box weights were 4lbs 2.9oz & 4lbs 2.86oz. I rotated the full box between weighings to make sure it wasn't skewing the scale as I couldn't get it exactly centered. Obviously the USPS would have an interest in keeping their scales calibrated, though the 1.5 oz difference in two measures is slightly worrying. Still seems safe to say, though, that it's comfortably under 15 1/2lbs.

I have the same 17X7.5 TRD forged gunmetal finish wheels. I weighed myself on my bathroom scale holding the OEM 17" tire and wheel assembly from my 2020 Hakone edition and then holding the new TRD wheel with 215/45 Bridgestone Potenza Sport tire installed (wheel, tire, TPMS sensor, center cap and balancing weights included in both). The TRD package was 4 pounds lighter than the OEM package.
