Finally got the new wheels and tires put on.

265 60 R18

Baaaaarely any rub at full lock. Fully confident with some sand paper or a heat gun I can make it go away. Either that or if the tires wear down at all, even a little, it’ll go away. Ride is super smooth and road noise is noticeable but negligible. Love how the combo turned out.

That tire/wheel combo looks great! I'm a huge fan of simple 5 spoke wheels. Can you tell me the wheel make?

Ok guys, need some input/advice:

Ive now been driving on these for 1 week. Absolutely love the look, but took about a 2mpg hit on gas mileage and can feel the extra strain they’re putting on the engine. I don’t really coast any more and they just make the engine work harder due to the added weight and grip. Very slight rub at full lock. I knew this all was going to happen and I’m good with it, but here’s my question:

I have the option to swap out the tires with the same Toyo AT3’s but in 255/55/R18 for free. It would eliminate the rub, but do you think it would have much impact on everything else? Think I’d get less stress on the engine/slightly better gas mileage?

Long story short, need to choose between 265/60/R18 or 255/55/R18.

Thoughts?

I think you need to look at the tire (and wheel) weight. Not sure about the wheels, but the OEM tires (265/45R20) are 29lb. The Toyo AT3s are 40lb (265/60R18) and 37lb (255/55R18). More weight = more load on the engine to rotate those tires (right?)... Add up the total weight (wheel+tire) to compare total mass being rotated at each corner.
I've been running Toyo AT3s in 265/60R18 since last fall and love 'em.

What's your intended use? What are you trying to achieve? The major reason to go with the 265/60 setup is to maximize ground clearance.

Daily driver that can handle snow in the winter and light-medium off roading in the summer. Added ground clearance is definitely a plus. I’m thinking downsizing to the 255/55’s is going to significantly reduce the ground clearance but Im not sure. Also worried they might look kinda small for the car/wheel well. Been trying to find pics of that setup.

Thats true.. thanks for getting those two weights for me. I’m wondering if the 3lb difference would even be noticeable. That accompanied by a smaller Diameter I’m thinking might be an improvement but I’m not sure. It’s so hard to tell without being able to try it!

The diameter difference between the two sizes is 1.5 inches, so that would be a .75 inch difference in ground clearance. If your going do do any moderate off-roading that is significant. The passport has limited clearance already.

Thanks man that’s helpful. I do have a 2 inch lift I’m planning on installing So I’m mostly just concerned about the performance aspects of going from 265/60 down to 255/55. Also concerned they might look small or undersized.

So hard to tell without driving on them or seeing them on the car!

I understand, I went through the same thoughts when selecting mine. I don't have a lift on mine. I didn't have any rubbing on mine either, though when the fenders were filled with mud I could feel the tires contacting the mud when doing the reverse full lock maneuver often described here. In my opinion, this is a none issue. During all on road and offroad driving there is absolutely no rubbing. If I never planned on going offroad of any significance, I would have either stayed with stock tires or considered other tires. I did see a slight decrease in mpg, but don't really feel any acceleration decrease. Heck, this is a suv, if I want performance I take my Spyder out for a drive.

So I ended up sizing down to 255/55/r18’s today and so far I’m happy with ‘em. 0 rub even at full lock, better asphalt performance and gas mileage. Probably did lose a lil bit of clearance but that’s ok.. when I say light to medium off-roading I do light wayyy more often so it should be fine.

Taking it out camping on miles of dirt roads this weekend to test ‘em. Cheers!
