Hello Everyone, I am a new member. Been on here a lot as I purchased a new 2020 Accord Touring that I’m tinkering with. Have found this forum to be a great source of information.
Anyway, on to the reason for my post. I had a set of BBS wheels put on yesterday. The wheels are the same size as factory, except for a bit more negative offset. So I decided to use the same tires as they only have a bit over 300 miles. Plus, it’s a quality tire that so far, I like. When they swapped the tires at Big O Tires they discovered larger plastic strips mounted on the factory wheels. They told me they believed they may be my TPMS Sensors.

This came as a surprise as all the research I had done lead me to believe these Accords do not have TPMS sensors. I called Honda service and the advisor I spoke with apparently didn’t know what she was talking about. She told me they were my TPMS sensors, but it seemed she believed I was talking about traditional small valve stem mounted sensors. I’ve worked in automotive service for years myself, granted over 11 years ago, and I’ve never seen these before.
Big O staff wasn’t sure so told them to go ahead with the swap and if the TPMS light went on, I would figure it out with Honda. I set my TPMS system to recalibrate after the job was done and so far so good. No service lights, car drives great.
So can anyone educate me on what these pieces are and do?

So they are made for sound cancelling? I was thinking that may be the case. If so, I will need to see what difference it made by removing them. I have to admit, the car was very quiet and my wife and I really liked that about it.

Only in certain pavement Changes & in those Area's @ certain Speeds . .

I Recently have been Testing Lightweight ~ Alu. Lugs and It seems with these - there is more Sound ..

~ . . ~
Yeah, well the wife already feels that it has affected the ride quality. I think it’s in her head. I feel it’s made I tiny difference in sound, but with the lighter wheels I think it feels nice. Very smooth. I was going to get an alignment done because the new wheels are a different offset. Went from +50 to +40. Don’t think it will actually change much but what do you guys think? Will it actually affect the alignment?

Thanks Jolivas : Good Catch - I have to scratch My Head and wonder why No One has mentioned this like 2 Years ago ..

I'm also wondering If Honda has found - Knock sensors to be so Very Sensitive that ~ Road Noise ~ ! also Translates into Vibs on Knock Sensor . .
As My MPG with new "Lighter Wheels"
Is Improved , but Mostly in the Average Cruising Range 50-65 Mph up above 70 Mph to 80 Mph No Improvement @ All
Even with Tire which are Proven Better Mpg with Less Rolling Resistance . .

That said - New Rims are a Tad Wider , Not as Aerodynamically Designed . . Makes Me Pause thou and Think those little Tweaks shouldn't be doing this . ?

Hence My Wondering
, as it seems These Wheel Items Honda Engineered are a Bit Much for Honda to Go that Far out on Limb for Sound ,as there are ~ Plenty of Lightweight Materials
~ to Reduce Sound ..

NOT have to " Reinvent the Wheel "

Then I Factor in - No Reports from Other Lightweight Wheels be added to Accords Dropping 40-49 lbs , NO One has Mention Better MPG . .
I Know for Fact on Other Vehicles in Past ( Lightweight Wheels ) Always meant 1-1.5 Mpg on Older Rides ..

We have Chassis that may not be as Heavily Built , Materials being more Sound Sensitive , Sensors & Engine Computers @ Lighting Speeds , may just be Adjusting Out Timing
~ Due to Vibrations from Road Sounds ~

PS: Jolivas , If you get a Chance does it seem those Items inside Rims - are Filled with Liquid or Gel ?

Thank You
Hey sorry to say that I won’t be able to check those wheels, at least for a while. I’m battling with cancer and my condition has taken a turn. It’s very difficult to get out of bed at the moment. From what I felt and remember I don’t think it’s filled with a liquid or gel. Who knows though.
