Question:

E-trailer hitch. Just bought 2025 Acura MDX with Technology Package. Comes with spare donut not full size spare but donut has 19 inch rim. Will the trailer hitch fit? Ive installed your e-trailer hitches on our 2014 MDX and on daughters Honda Pilot - no problem. if it doesnt fit, what alternatives do I have? Any recommendations?

Hey Ralph, thanks for reaching out. The etrailer Class 3 Hitch # e27KR is the correct fit for the 2025 Acura MDX. Unfortunately, this hitch will not allow the spare tire with the 19" rim to fit under the vehicle. According to the manufacturer, only spare tires 18" or smaller will fit under the vehicle with the hitch installed.

We offer 3 different hitches for the 2025 MDX and they all have this same restriction for the spare tire. Only the 18" or smaller spare will fit. If you need to install a hitch you will need to get a smaller spare or find a different place to store it. I wish I had a more helpful solution for you, but this will be your only option for installing a hitch. Feel free to reach out if you have any other questions.

Hey Ralph, did you end up going with the Class 3 hitch for your MDX or decide on another option because of the spare tire size? Your update could make it easier for others with the same setup to plan their hitch choice.

@JesseM I have a 2024 MDX Advance with the spare tire that came with it and am soon upgrading to a 25 Advance due to it's massaging seats and my wife's strong desire for touch screen navigation! The spare tire that came with my MDX was no problem at all. Do not recall the exact size but I had to trim the hands free access panel and flip that controller 180 degrees but install was not bad for anyone with decent mechanical skills. I have checked and the 25 MDX is same physical specifications as the 24,I am just gonna remove the hitch and install on my upcoming 25 MDX. Patrick
