Alternative OEM wheel and tire size to maintain similar dimensions and ride height, below. Use a Tire Calculator to confirm dimension differences and effect on speedometer.

Passport:

• Tire 265/45R20 (Wheel 20x8.5J ; Offset 55) = Circumference 92.3" = Diameter 29.4"
• Tire 245/50R20 (Wheel 20x8J ; Offset 55) = Circumference 93.1" = Diameter 29.6"

Pilot / Ridgeline:

• Tire 245/50R20 (Wheel 20x8J ; Offset 55) = Circumference 93.1" = Diameter 29.6"
• Tire 245/55R19 (Wheel 19x8J ; Offset 55) = Circumference 93" = Diamter 29.6"
• Tire 245/60R18 (Wheel 18x8J ; Offset 55) = Circumference 92.9" = Diameter 29.6"

If you wish to maintain the same bolt pattern, offset and hub diameter (see post #1), you will likely have to use a Honda or Acura wheel.

18" may be the smallest wheel that will clear the brake calipers? It would be good if someone confirms.

If you search the internet (Craigslist, Facebook Marketplace, eBay, etc), it is possible to find used Honda or Acura wheel sets that fit. I have found a set of 18" wheels from a Ridgeline that I will re-purpose for winter duty.

Example of tire size comparison:

Nice, let us know please. I can’t handle 20’s. Typically they ride like crap, and to me, old timer look dumb. Also Chicago streets eat up 20”rims

Just returned with my acquisition. From a 2018 Ridgeline (higher level trim)... 18x8J & Offset 55. I'm certain they fit. Will not be installing till the fall with winter tires. All 4 wheels were "like new" condition.

Cool, so what size tires do you plan to put on these rims?

I plan to install 245/60R18 which maintains approximately the same tire dimensions (diameter & circumference) as 265/45R20.

Tire Rack listed 255/55R18 for the Passport which I believe is wrong with a larger differential.

Does anyone know if Acura rims will fit right on?

You can verify the spec of another vehicle's wheel on the internet like this. This is for a 2017 Acura MDX that would be compatible.

Some wheels will fit and you will have to check/verify the spec...

• Bolt pattern: 5 x 120mm ... If different, it will not match up to the Passport wheel lugs.
• Offset: +55mm ... If you wish to match the same factory offset for the Passport.
• Hub diameter (Center Bore): 64.1 mm ... If smaller, it will not fit the passport. If larger, it will require a centering ring.
• Wheel Size: 18" diameter or higher will work. There may not be sufficient clearance for the brake calipers with 17". Width will vary based on wheel diameter and tire size to be mounted.

Physical verification on the backside of the wheel spoke, some specs are stamped into the casting. "18x8J 55"... 18" wheel, 8" width, "J" type lip, +55 offset.

I know it's a long way off, but when you get these mounted, please post an update and pictures. Thinking of doing the same thing when the original set of tires are ready to be replaced, so very curious to hear how you make out with this. Thank you for all the info in this thread.

Yes, will do. The Ridgeline wheels (same offset, bolt pattern, hub diameter) and 245/60R18 tires (nearly same tire diameter) should work without a problem. The Ridgeline and Passport are built on the same platform and share many of the same components.
