Official 2022 Tundra 3rd Gen Thread

Well damn. I thought the air suspension was supplemental for the rear coils, not the primary.

 

I remember trying to find a lightly used LS460 a few years ago. Everyone suggested to find the versions with the "steel suspension" meaning coil springs and not the air ride option. The air ride was very prone to issues.
Turns out, since I wanted AWD, those with coil springs were like unicorns. I eventually gave up and bought an Infiniti instead....

 

They should have just used the AHC system off the lx570. It's relatively trouble free if you keep up with maintenance and it's stout. Many people pulling travel trailers and boats well over the rating as well as cargo loads over with no issues.

 

gnc1017 posted that you can manually set the psi with an adjustable screw. I'm going to look into this.

 

While it may be stouter than some, a quick google search of LX570 AHC system yields forum pages upon pages of AHC system problem threads and issues as well.

What they should have done (if they wanted to keep the tundra legendary reliability in tact) is offered a payload package with better springs to compensate for the toyota notoriously inadequate soft springs and leafs. Or they could have done what Ram did with their 2500 coil spring set up and added a shock in the middle.

 

There might be hope yet for achieving rated fuel economy.

91 miles @70 mph and he got 24.5mpg.

Sorry if I caused confusion. The screw adjust picture I posted was for headlight adjustment, not for the air ride. Hopefully, that screw adjustment will allow resetting of the headlight height (especially for those with the auto-level feature) when a front leveling kit is installed.

They've got to fix the auto-level when not in tow mode. Only reasonable option.

That is really good gas mileage.

I usually get ~16

 

I have to question his calculations considering how many times he screwed up the test. I believe 20 but 24+ going 70? I really doubt that.

 

No problem at all, you encourage me to dig a little deeper. I found a video on YouTube on how to adjust your air suspension preset. The picture you took shows a bracket arm with a nut, that's the preset . Thanks gnc1017

 

Knock on wood, our 2012 Lexus GX460 premium has auto leveling and AVS shocks and it has always worked awesome. Love it, especially on road trips when heavily loaded and windy out. It's more of a handful and tiring until I put it in sport mode and then it's 100% better and less fatiguing to drive. Main reason I'm looking forward to it on a new Tundra, with hopes it will then be our road trip vehicle going forward. Sure hoping Toyota didn't screw up the Tundra's implementation in such a way it can't be corrected.

Also have it on my 2015 GS450h F-Sport and it's been reliable and works great on it too but with only 25k miles, it's had more age than use...

 

Agreed!

 

Almost 2 mpg more than the trip computer. His test is shenanigans

 

I thought that as well

 

Guy colour matches the grille frame and other chrome parts on his SR5 TRD O/R. Looks perfect.

For those in TX, almost all interstate highway has 80 MPH speed limit, and most go 5 mph over so realistic cruising speed is 85 MPH

would you really go 70 MPH in TX in order to save gas but have 18-wheelers passing you constantly?

 

I would.

 

I did some test myself, at 85 mph I get 15mpg, and around 70 mph I get 22 mpg, it's crazy just 15 mph difference it wastes so much more fuel. It makes me suspect if big oil was behind the push to increase speed limit as they stand to benefit a lot

 

New 2022 Tundra Suspension:

✅newly developed double wishbone front suspension

✅ front suspension benefits from a kingpin offset angle reduction to enhance straight-line stability and high-speed driving

✅ caster trail has been enlarged from 25.4mm (1 inch) on the previous generation to 34.1 mm (1.34 inches) for added stability

✅ roll steer has been reduced by 25% compared to the benchmarks, and the roll height center has been elevated (152mm compared to 104mm, or roughly 6 inches compared to 4 inches) to reduce body roll, especially when cornering

✅ Beefy NEW aluminum forged knuckles for reduced weight , prevents corrosion & stress cracks and there are steel inserts to reinforce ball joints

✅Air springs: Available on the SR5, Limited, Platinum and 1794 Edition, rear air springs replace the coils. They can vary rear suspension height up to 2.5 inches, but you can’t pair them with any TRD package. All TRD models, including the TRD Pro, have coils.

✅Air springs and adaptive shocks: Available on the Platinum and 1794 are adaptive shocks, marketed as Toyota’s Adaptive Variable Suspension system. They replace the passive shocks but pair only with the air springs.

✅ Tundra will feature standard twin-tube shocks at the front and rear of each truck

✅ TRD Off-Road package provides monotube Bilstein shocks improve damping for on-and-off highway driving

✅ TRD Pro gets even beefier diameter Fox internal-bypass shocks (2.5 inches versus the 1.8 inches for the Bilsteins) plus a 1.1-inch front suspension lift and a thicker front stabilizer bar that’s 20% stiffer.

✅AVS system (REMEMBER can only pair with Air Shocks) is designed to adjust damping force based , the AVS features built-in actuators in the FRONT and REAR shock absorbers to continuously change damping force based on the conditions, all to enhance handling, stability and comfort

✅ The Tundra hybrid (not available yet) gets unique suspension tuning due to weight differences

Note you could have air shocks alone except with TRD OR package or combine them with AVS package again not with TRD package

 

Not Texas, but I’ve been commuting to Toronto, Canada on a few of the Queen’s highways for over 24 years. Sit in the slow lane driving the speed limit (100kph/62mph). Look as far down the highway as I can. Anticipate merging traffic. Slow down to let vehicles merge onto the highway because every single one wants to get over to the fast lane and drive faster than I do. Zero tickets. Zero accidents. Saved a ton of gas in 24 years. Maybe enough to buy a new truck! Lol

 

Um, ya. If I recall, every kph above 100kph equates to a 1L/100km increase in fuel consumption. Somebody else can convert that to American.

 

It won't be that bad or going 120 would be normal plus 20L/100km (around 35L/100km) and even my 2020 doesn't get that bad mileage. Every 10kms over maybe.

 

I disagree but I think the more interesting part of the video was when he explained the reduction in emissions, that other Toyota vehicles will share the same engine and that Toyota sells vehicles worldwide.
This is the future. Hang on to your V8 and even your ICE trucks as long as you can folks!

 

Grams per what?

 

I believe the EPA GHG is g/mile.

 

Doubt it. But in Montana I know they never had a speed limit but the feds told them they had to have one so they set it to 80 as that was the highest they could. 80 mph is basically no speed limit imo lol

 

That doesn't seem right. At 100km/h, I average 13.5L/100km. At 120, about 15L/100km. This is in my '05 with the 4.7L V8.

 

This is CO2 emissions per mile. Tim kept saying NOx but that’s another story…
Carbon Dioxide grams/mile is directly correlated to miles/gallon. So as mpg goes up, CO2 grams/mile goes down. We can calculate how much CO2 is produced in the combustion process due to the stoichiometric air/fuel ratio. So 460 grams/mile is about 19 mpg.
