Keep in mind that if your speedo says you’re going 70, you’re actually going 78.8 mph, unless you’ve recalibrated to your new tire size. State troopers will really like you.

At 60 mph my actual is 65 using a GPS app on my phone. And no worries about speeding or troopers troopin. I enforce traffic for a living too! #harley

You should just use Fuelly. You could put away the dry erase boards lol
I just use my brain to figure that stuff out. I'm always doing tire/size/speed swap calculations when I'm bored waiting around or doing mindless work. I do admit to using a calculator when the numbers get big going from rpms to top speeds and a unit converter when dealing with metric tire sizes. Gall dang millimeters.

So the trucks estimated mpg on the gauge cluster of 22 is only about 1 MPG off. That is closer to the true number then I though it would be with the bigger tires.

It looks really good with the 32's

I wonder if forscan could fix the speedometer problem with the larger tire size.
I know it has some built in values, but I believe they are only the different stock sizes.

I'm personally not too worried about it. I would have that correction made if I ever have it tuned.

Not going to happen. Too much cutting
Ridgelines still have nothing to fit true 33 far as I know

Who said I was scared of cutting. You've obviously never seen a redneck put super swampers on a Miata. If there's a will there's a way. I've never been one to have the same boring vehicle as everyone else. Please get off my thread.
Maybe we can get ahold of soft offroad rolled Bronco chassis and some 4x4 lumber. Since the unibody doesnt have the skirt to sit over the frame it will he higher and the Bronco handles 37s. I am thinking 39.5 Swampers will be just about right. Does forscan mate programming across models?

Found it interesting you can only get 20" wheels on the Rivian. The 20" wheels come with skinny AT tires and the 21" wheels are street. Should be a pleasant off-road ride with the AT's..

LOL.
