Back to Stock wheels?
 

I am think of going back to my stock wheels on the 2015 MDX. My Vossen VFS-2 are lovely although I do miss the acceleration with the stock wheels on. Where is a good place to get of OEM TPMS for the 2015 so I can mount 19 wheels back to my Original wheels? LOL.

An online search of OEM Acura parts will return you many viable online OEM part retailers. Most prices are in the same ballpark. The differentiator will be the shipping cost. Most, if not all of the sites are run by dealerships. You could price the parts online and contact your local dealer to see if they would match the prices. If they won't match, order them online. I have used several of the sites without issue.

Have you considered non-OEM sensors? I ask because there are any number of vendors, from TireRack on down, with available aftermarket sensors which are 100% compatible with your TPMS system; and most are significantly less expensive than the OEM sensors.

Edit: Out of curiosity I looked up the sensor assembly for my 2006 TL on both Tire Rack and Bernardi Parts, would you believe the TireRack unit is $44.00 while the OEM unit from Bernardi is only $33.32; yikes makes me look like a total chump! :tongue:

I found that out a couple years ago when building a winter config for the wife's TL. I was amazed at how inexpensive the OEM TPMS sensors were, especially online. You just need to remember to get the washer and nut at the same time, since the sensor itself doesn't have those 2 pieces. But even at that, you save a good chunk of change over the aftermarket options.

When it comes to wheels, apart from styling and offset, the most important is weight and strength of construction. That is key to better handling and better mileage. When I swapped out my wheels for the supra, I went from 23-26lbs per wheel to 17lbs per wheel from Wedssports Racing. thats ~30 lbs of rotational weight and supposedly in internet formulation, that is 30x6 = 180 lbs in stationary weight. It would be interesting to know what the OEM offset wheels are.

Keep in mind the weight of a wheel is only part of the rotational mass equation. Said another way, a 23 pound 17" wheel will have a lower rotational mass energy calculation than say a lighter 20 pound 19" wheel.

I think it does get more complicated though. you got to consider the weight of the tires as well with such different sizes. Weight of the wheels do tend to get heavier with bigger diameter too. Im no expert and so I'd keep it to apples to apples comparison of 20" stock vs 20" aftermarket if possible. Almost nobody went with oem 17" sizes in the Supra world and people were going 18", 19", even 20". I stuck with the 17" for lower overall weight vs larger wheels.

anyone has info on the OEM spec of the wheels? 20", offset and weight would be great for aftermarket comparisons.

Apollo2TheMoon - say it isn't so, you were my inspiration to get 20" vossens. These were the honda/acura oem tpms I purchased and put on my vossens:

Hmm dang, the VFS2 + tires in 20s are that much heavier that you can really notice the change in accel eh? That's a shame, although not too surprising I guess, as Vossen's cast wheels are just about as heavy as any other aftermarket cast wheels of the same size (IIRC, these are about 30lbs each, but maybe Vossen can confirm). Now I wonder how much the OEM 5x120 20" MDX rims weigh..

Whoops said cast but meant that flow form thingy they do.

Matters not, a light 20" wheel will cause slower acceleration and braking than a "heavy" 17" wheel.

Yes, we all know that since it's simply physics that but that's not my point. It's about whether or not it's really that noticeable enough (or at all), especially going from 19" here to 20" (albeit wider), to want to go back down in size. Apparently it is. I've gone bigger on other cars, but haven't really noticed differences in acceleration and braking substantial enough to want to return, but the MDX is both slightly low on torque and its brakes are also slightly too small for its weight, so I think this is why it shows.

they are expensive but just showing how much lighter they can get at less than 25lbs a piece at 20" and strong. so the sport hybrids are 5x120 eh?

2017+ is all 5x120.

Sorry, I let you down brother.

I do believe the VFS-2 is indeed heavier but not know how much. From a stock 19 X 8.5" to a 20 X 10.5", that generated much more rolling resistance. But believe it or not, I do get the same mileage if not better, I am able to do HWY only driving above 27-28 MPG per the car. On stop and go traffic is another story though. I think for heavier wheels, they function like a train, more time to pick up speed but once it started to rolling, it will going.

Do these fit the 2015 MDX bro? It started that it will not fit the 2015 MDX.

I got my 2015 MDX back to stock wheels. The 19 X 8.5 in stock wheel weigh in at 60.9 lbs each, surprisingly the Vossen 20 X 10 in weigh in at 60.2 lbs. The Vossen flow form does make the wheel for sure lighter.
