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.

 

[DudeCS]

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.

 

[DudeCS]

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.

 

[DudeCS]

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

My winter tires (Michelin Latitude X-Ice Xi2) and wheels (Honda Ridgeline) mounted on the PP. With the smaller wheel and more sidewall, the ride is softer and more compliant over bumps.

 

[DudeCS]

Could someone please explain (again) the following:
1) When do you need to use spacers? And what do they do? And what would happen if you did not use them?

2) Explain the Offset and what happens when you use a rim with less off set?

BIG THANKS!

This page on Tire Rack is an explanation for wheel offset. Note the last paragraph on how offset can affect your vehicle.

Adding a spacer would increase offset of the wheel, resulting in a more positive offset measurement (moving it outboard). The spacer should have the same bolt pattern as your wheel hub and same hub size (to keep the wheel hub-centric). Oh, but you cannot add a spacer without changing out the studs versus European cars that use bolts!

A wheel with a lower offset versus OEM would be more inboard.

 

[DudeCS]

Thanks Dude, I read it, but I'm still fuzzy the Passport.

The offset for the OEM wheels is +55mm

There are NO 18" wheels shown on Tire Rack that are +55mm

There are 97 wheels with between 38mm and 45mm offset, will these work?

If you use a wheel with 12.7mm (0.50in) difference in offset, does that mean the tire will stick out an extra 1/2 inch?

At what point would the difference be too great and a spacer would be needed?

anyone?

Yes, that is the predicament if you wish to maintain the OEM +55mm offset. It is nearly impossible with aftermarket wheels.

With the lower offset number, it means that the wheel will be more inboard. If you are going with a smaller wheel and narrower tire, you will likely not have an interference problem.

Options...

1. Buy OEM wheels, either new or used. I found a set of used Honda Ridgeline 18" wheels at a great price (same offset, bolt pattern, hub size). Current generation Honda Ridgeline or Pilot wheels will work. Search locally on Facebook Marketplace or Craigslist for a nice clean set. There are probably a lot of Pilot wheels available.
2. Buy refurbished OEM wheels... current generation of Ridgeline or Pilot wheels will work.
3. Talk to a sales rep at Tire Rack or other wheel supplier for their recommendation and advice.

Adding a spacer is not an option or not practical with the wheel hub. The existing lug would not extend far enough for the lug nut.

Remember that you will need a set of TPMS sensors or move them from your original set.

 

[DudeCS]

So my question is. Is there a wider tire that would go on an Elite rim to keep the wife from hitting the rim on curbs. Second set she has hit.

Some tires feature a "Rim Protector" (see photo #2 & #3). It is not foolproof, but may help. I think the Michelin Pilot Sport A/S 3+ (265/45ZR20) is one that has a rim protector.

 

[DudeCS]

A wheel with a lower offset versus OEM would be more inboard.

@stevenD ... Sorry, I got this backwards. A lower or more negative offset would move the wheel outboard. This is a better diagram of the difference for positive vs negative offset. With the lower offset of aftermarket wheels, it will be slightly closer to the fender lip. If you are using a narrower tire, it would likely negate the changes due to offset.

 

[DudeCS]

Question, were you able to use the stock tpms sensors?

Yes. I bought a second set of sensors for a separate set of winter tires and wheels. See this thread. You only need #1 because it is a "kit" that includes #2 (nut) & #3 (washer). Just "plug & play"... no programming of the vehicle required.

 

[DudeCS]

My bad I guess I did it ask the proper question. The stock tpms sensors from the ridge line is what I’m wondering if they would work

I believe YES. The part number for Passport vs Ridgeline is different, but probably the same. Tire Rack lists the same TPMS part number for both.

• Passport P/N: 42753-T6N-E02 (TPMS kit)
• Ridgeline P/N: 42753-T6N-A01 (TPMS kit)
• Same for both TMPS (433MHz) P/N: 42753-TG7-A51
