20 inch wheels vs 18 inch wheels

12350 Views 35 Replies 16 Participants Last post by  Coyotefred
Dear Passport owners:

The 20 inch wheels on our 2021 Passport Touring, while they look superb, may be making rides slightly bumpy. My comparison is our old 2011 CRV which has 18 inch tires. Has anyone here changed their tires from 20 inch to 18 inch on their Passport? If so, is that safe and acceptable on the Passport transmission?

Do 18 inch tires make meaningful differences in: a) Softer ride quality?, b) Braking distance reduction?, c) Traction stability?

I am satisfied with how beautifully the 20 inch wheels handle curves on highways and mountains. Was not sure if 18 inch wheels would worsen that?

Thanks!

It's a Passport. It is designed for off pavement like trails and the dirt road to your cabin or campsite. The stock 20" wheels and tires are just fine for what Honda designed the vehicle to do.
You may think so, but I definitely do not.
I know the Terrain Contacts are known for being quiet, but even with the Falkan Wildpeak A/T the road noise is not noticeably louder than the stock tires.
I upgraded to 265/50/20 Toyo Open Country AT3. I think it's funny how people complain about road noise. Of course going to an AT tire will increase road noise. Do people drive around and listen for every single noise? Turn your radio on. Open a window. Going with a larger 20" decreased the curbing issue as it added almost an inch of width and built in curb protector. Also going from a 20" tire to a 18" has nothing to do with height. You can have a tire in each size with the same height. You can up size in either size tire. In the Toyos I bought, the 265/60/18 is more expensive than the 265/50/20. The 20's can handle most anything thrown at them.
You may think so, but I definitely do not.
You are entitled to your opinion. Perhaps you know better than the manufacturer (Honda) who designed the vehicle.
They put 20" wheels and all season tires on the vehicle. Is that not a hint how the vehicle was designed and its real intended purposes. Also, just minimal ground clearance, minimal if any underbody protection, no locker(s) and all the other things that make for a true off road vehicle. I suppose you could modify a Passport to become a true off roader but, why not just buy the the Toyota or Jeep? The Passport is safely at best a trail, gravel or dirt road vehicle. Honda put the lipstick on a pig.

Have you not seen any of the advertisements for the Passport? I think those give a hint as to how they think people will use it. They increased the ground clearance over the Pilot. I guess that was necessary for paved roads, right?
Look, as I've said before, it's obviously not something you buy for rock crawling and true off roading. I don't think anyone buys a Passport for that, except maybe jonDZ.
I'd say it's intended as primarily an on-road vehicle that can also do well at light off roading or soft roading as it's called. Sure, 20" tires will still work for that but they definitely aren't ideal. Tires with more sidewall are better for that purpose.
I think there are many people who buy a Passport with the intention of taking it on some dirt/gravel/rough roads to go camping, fishing, or just getting out into nature, if only just occasionally. I will be surprised if Honda does not at least offer a 17" or 18" wheel option when the next generation comes out.

I hear ya and I agree. That increase to 8.1" will help you go over the roadkill on those dirt/gravel/rough roads 😁
Enjoying these tires referenced above on my PP. for me no noise issues and really like how they ride. Would recommend them for sure.

For those who have gone to 17” or 18” tires, are you still running the s as me tire pressure as the OEM tires?
I dropped my pressure down from 35 to 32psi going by the results from this website. Tire Pressure Calculator
The ride is a bit better with no noticeable loss in steering response so it seems like a good idea to me.
I'm not getting the curb rash thing. I 've been driving for way more years than I want to rememeber with all sorts of tires and wheels up to 22 inches and I've never experienced curb rash. If your running into curbs you need to polish up your driving skills and be more cognizant of curbs. Sliding into a curb due to icy conditions might be excused.
It can happen to the best of us. Even those of us w/ 37+ years of driving experience. More years if you count unlicensed driving experience as a young, cantankerous lad.
Best improvement I made was upgrading the Stereo, but a close second was going with 18" AT tires/wheels...!

YES: Smother Ride, Better road feel, less Bumpy, less road bumps transmitted to the steering wheel, NO CURB RASH, better handling in dirt, ice and snow, etc....
Our recently purchased (used) '20 Honda Passport Elite AWD is for my wife but that 540W stock stereo w/ subwoofer is pretty dang entertaining thus far. Surpasses(?)/rivals my custom stereo in my '04 Dodge Durango SLT.

Questions: What year/trim PP do you drive AND what avg. MPG are you getting after the rim/rubber swap?

Thanks in advance. ✌🏼

2019 Touring AWD, with OEM wheels/Tires, the best I got was 27.7mpg during a 300+ mile trip mostly downhill. The same basic trip with the 18"s and A/T tires - I got high- 25/low-26 mpg... or about 1-2 mpg less... not enough for me to worry about!

The 18's grip the road better and feel way more secure...!

I park on the street and haven't curb rashed my wheels yet. If you're careful it's not that hard. That auto tilt sideview mirror comes in handy.
With all of the damn cameras pointing in every direction on new cars, I can’t believe not one manufacturer has placed a camera in the passenger side rear wheel well

I guess you'll have to become a more proficient driver or you can get yourself a pair of curb feelers. They still sell them on Amazon for $14.99 a pair. 😁

No problems here, I use the mirror, just surprised it hasn’t happened.

I was surprised when I seen a Mercedes commercial the other day showing the first car to have rear front impact airbags, located in the back of the front seat headrests
I would like to know this as well. I just installed 18" Ridgeline wheels and Cooper Discoverer AT3 4S tires in 265/60/18 (110 load). I ran the calculator on that site also and it recommends 30PSI rather than the recommended 37 for the OEM tire size 265/45/20. That seems low to me, and presumably would be setting off the TPMS. So I'm curious too what others who have changed tire sizes have done as far as their new tire pressure.
