GM has developed a partnership with Michelin to develop airless tire and wheel technology. GM plans to begin testing the Michelin “Unique Puncture-proof Tire System,” dubbed Uptis, on a fleet of Chevy Bolts this year. Furthermore, GM says that it will be ready to begin volume sales by 2024. 

 

“General Motors is excited about the possibilities that Uptis presents, and we are thrilled to collaborate with Michelin on this breakthrough technology,” said Steve Kiefer, senior vice president, Global Purchasing and Supply Chain, General Motors. “Uptis is an ideal fit for propelling the automotive industry into the future and a great example of how our customers benefit when we collaborate and innovate with our supplier partners.”

This technology has been around for a decade and is used on some commercial construction vehicles, like Bobcats. GM sees the following benefits to the technology:

-Reduces the number of punctured or damaged tires that are scrapped before reaching the end of their life cycle.
-Reduces the use of raw materials, energy for production and emissions linked to the manufacture of spare tires and replacement tires that are no longer required.
-Lasts longer by eliminating irregular wear and tear caused by over- or under-inflation.
-Reduces dangers related to flats and blowouts.

 

 

Are we crazy, or dies this technology look perfect for off-roading?

Would be a milestone if this technology came on vehicles from the factory :thumbs:

Perfection for certain Off-roading.... absolutely!

I am curious as to the cost difference between this type of unit and a conventional tire.

Great find John.

Imagine it freezing solid with that flat spot from the cars weight. You ain’t driving it with a flat spot frozen into it.

 

Michelin Tweel never came to market due to DOT requiring air in tires to operate on highways.

According to Michelin, on the ground at the introduction event: Not yet for off road vehicles. Second, the tire is supported top-down, not bottom-up as is a conventional tire.

Another great idea on paper.  Works great on the computer, and on the test tracks in perfect climates with freshly paved tarmac. 

 

Meanwhile, in the real world, where we daily have to drive for miles on a rough dirt/gravel road to just get to a paved county road full of potholes, through snow drifts and across low-water bridges with 8 inches of water (or more) running across them, we just can't wait until snow/ice/mud/gravel get stuck inside all of those little slits.  Talk about your can't-get-rid-of-it, always-changing permanent Chevy shake!  I can hear a service manager's answer to the warranty claims now, "Performing as designed."

 

Right about now, GM is wondering how they will mandate dealer-only UPTIS rotations, to keep their service dept $ flowing, since there won't be any more TPMS.

I would imagine these would got through extensive on/off road testing with something like millions of miles performed before they are released to the public.  Also I see less waste as these probably would be taken off and sent back to have new tread put back on.

My analytical mind has to ponder however............   what happens when foreign objects, mud and debris enter the open vanes?

This would indeed throw off balance.

Engineers have hopefully or are currently investigated this issue :rolleyes:

      Gas fill door

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
