245/65/17 KO2

Did you get a spare as well?
If so does it fit in the designated spare location?

 

[JohnSilver]

Been running k02s 245/65l17s on an 8in wheel with 30mm offset on my big bend, no lift. Have had no issues with rubbing at all. My only gripe is weight of this tire, kills my mpg it seems. Will probably go with Falkens or Toyos next wheel it'll drop about 7 to 8lbs per tire

No, kept the pirelli… I figure if I nuke a KO2 I can use the 225 like a donut…

The Bronco is not a daily car for us so MPG are offset by our EV ?

Yeah that's true, as long as you don't have some massive obstacles to go over to get out of the situation.
I ask cause I'm curious if the 245 would fit. Some say it will if you give it a shove, and some say it's not even close. ?

Can’t see these fitting, plus I have other gear there

Not really my daily either but when it gets the same mpg as a big bronco I'm kinda like ?. But I did forget to mention like was brought up earlier, road noise is another problem I have with them. Besides that sweet looking tire.

 

[LBinWNC]

Yup more noise for sure

It's likely not just the increased weight. A wider tire has greater rolling resistance and frontal area, both of which require more power to overcome. The biggest drawback to increased weight is the loss of acceleration.

By the laws of physics I would agree, however after speaking with a few others running Falkens and Toyos at 245/65/17 (3 cyl) averaging 25-26mpg and not 21-22mpg (my case). That's enough objective measurement for me to switch eventually.

however, I have considered factors that may effect this, my area is very hilly Knoxville TN, driving is more aggressive in these cases. Altitude? However after spending a week in flat highway land IL I had the same outcome of 21-22mpg average.

I've also considered the possibility that they are just lying about their mpg lol

A 245/65/17 or 245/70/16 or 245/60/18 spare can fit in the well if you sacrifice the padding. Check out some pics here.

I don't know why people do this, but I've found this to be VERY common. I've had long discussions with folks regarding the use of premium fuel. Some swear on their children's eyes they get better fuel mileage using premium. I've been tracking fuel mileage on my Badlands since new (and on my EcoBoost Mustang previously). Based on my data there is no improvement in fuel economy using premium, at least in my car(s) for the way I drive.
