I need a lot taller sidewalls for long dirt road ventures. The stock Passport tires have an outer diameter of 29.5". My EX-L has 245/50R20.
I'm thinking of the following options in order:
235/75R17 which are 30.9" and obviously 10mm narrower, or
235/70R17 which are 30", or
245/70R17 which are 30.5", or
245/75R17 which are 31.5"
I like the idea of little narrower and taller for the type of driving I'll be doing.
Pontificators and experts alike I value your opions please...
Also considering 16" wheels but on the fence on that option for now.

Are you planning a lift up front? I know it's early, so we don't have a clear idea of what is going to fit, but I suspect the 245/75's aren't going to clear at lock. for everything else, I would say that it's more a matter of what particular tire that you like in a given size range and what it weighs/construction than anything.

I would like larger tires on a passport. my only concern is the Honda safety sense.. if the speedo is off does that throw the system off and cause false reactions? I do not know, just curious

There is not much room in the front wheel well between the wheel and the liner when the weels turned all the way in either direction. I would say, with OEM rims for Touring and Elite wheels of up 30.5" diameter will likely fit. Any bigger might start rubbing. Still needs to be tested.

If the rims are aftermarket, it will depend on offset. As we know the OEM rims have +55 offset. So far I have not seen any aftermarket wheels with such value, +44 max, but typically between+35 and +40. The smaller offset will push the wheel out and give a little more room between the wheel and the liner when the wheel is turned to the side.

Good info Sib...!

JSport seems to have something in the works too:

 

[emilyblankenship]

Honda Sense wouldn't know about a slightly larger wheel. It would think you are traveling slightly slower than you actually are. The ACC would still monitor the car ahead and increase/decrease relative speed accordingly. At least this is my speculation.

With respect to taller tires rubbing on full turn stop, that is a concern and I don't plan on lifting. I'll take some clearance measurements before making a decision. The narrower 235 tires should help and as Sib pointed out the wheel offset comes into play as well. I'd prefer to keep the wheels as close as possible to the body because the Passport is already a very wide beast!

Good find. JSport partners with Honda on their accessory wheels (made by KMC Wheel). They will have the OEM hub diameter.

My adaptive controls seem to be behaving normally with the larger wheels.

My wheels exhibit a very slight amount of rub, not to a point that I am concerned. I've posted photos in the "Post Your Aftermarket Wheels" thread.

 

[mbrooks]

For upsizing, do you guys also change your spare tire??

 

[madison38]

I'm currently keeping the small factory spare, but I'm planning to get matched spare before any long haul adventures. I've been toying with the idea of trying to get a larger wheel in the spare tire well under the floorboard, but I'm leaning towards carrying the spare elsewhere depending on the situation (attached to a trailer etc.).

Off topic but how’s this one tow? ~what weight do you tow and how’s she handle

I'll be hitching up a small rental camper trailer for the first time tomorrow. It weighs very little, I think around 800 lbs dry.

I'm only planning to tow an off-road teardrop camper at the most in the near future, but it's nice to know I have the option to go bigger if the need arises.

I think Jsport has these tires mis-identified. Picture on the right is a General Grabber AT tire. I think the picture on the left is the ridge grappler.

I'm planning on getting a Passport Touring soon and have been doing some research on all-terrain tire and wheel combos. I wanted to post what I've found so far for everyone's reference and to also get some feedback from the group (first time looking into this stuff and not an expert by any means, so all comments welcome). I appreciate what everyone has shared so far.

My understanding is that a 30" diameter tire is the largest size that will fit without rubbing in a stock configuration.

Stock tire for touring and elite: Continental crosscontact (265/45R20 104H) revs/mile: 707 dia: 29.4"

Largest AT tires in 29 to 30 inch range for 18 inch wheels:

Nitto Terra Grappler (255/60r18) dia 30
Nitto Ridge Grappler (255/55r18) dia 29
Continental TerrainContact A/T (255/55/r18) revs 716 dia 29
Continental TerrainContact A/T (245/60/r18) revs 702 dia 29.6
Yokohama Geolander A/T (255/55/r18) revs 715 dia 29.1
BF Goodrich KO2 (255/55/r18) revs 717 dia 29
General Grabber AT2 (255/60R18) revs 692 dia 30
hankook dynapro atm (255/60R18) revs 692 dia 30

I've been looking for 18" all-black wheels that will fit and this is what I've found so far:

KMC km708 bully
KMC km716 nomad
Black Rhino York
Black Rhino Overland

I'm currently leaning toward the Terra Grapplers on KMC bullys. Anyone have experience with how much road noise to expect from the Terra Grapplers? From what I've read online they are on the low end of noise for an all terrain tire. I currently run Goodyear Duratracs on my land rover for reference.

 

[david16]

Ha. Taking my potential set-up! I'm also looking at the Bullys and Nittos. Great minds think alike!

Had Nitto Terra Grapplers on my previous Tacoma and Wrangler before that. I personally wouldn't think twice about getting them again. Great tire. Can't compare noise level of them but I didn't find them "loud". Before the Nittos on my Tacoma I had the Continental TerrainContact A/T. Couldn't get them to balance, changed them out for the Nittos and never looked back.

Side note: remember that overall diameter is one thing but the wheel offset is another area that could cause rubbing.

On my touring model , I have cooper AT3 4s tires size 265/50/20 I’m not taking it off road in extreme elements . Just snow , rain ,dry . On normal mountain roads or highways . Ski resorts , Lake Tahoe etc.

So the 265/50/20 tires fit and work fine?

 

[theresayoung]

I had my tire guy look into it , they even put them on . They fit fine , looks aggressive . Total diameter is 30.4 inches. But realistic it’s only 1/2 inche, higher on top because how it sits. It’s fine for what I need it , not extreme off road that probably wouldn’t be good . I looked into this because of a member on the PP forum said the 265/50/20 tires work. Without changing the rims size . Hope this helps you.
