Can someone tell me what is the largest size tire (all-terrain) that will fit on a stock AWD EcoSport (USA version) without rubbing? Also, have been searching for the rear tire carrier and cannot find it... any links would be appreciated. Also, anyone try lifting one to fit larger tires? (Haven't bought one yet, but it is so far first on my list).

Frankly, I would be interested in some tires that are a little less "low profile" without having to change the rims / get the vehicle reprogrammed for the larger wheels. I already destroyed one on a curb haha.

Octotron, did you ever do anything on this? I am looking for better ride with an taller tire. More air and tire between me and the road. Not sure why Ford would put low profile on an SUV. I want to keep the 17 and go taller.

There's not much room to go taller with the 17" tires. Factory they are already 50 series tires. My 16" are super comfortable.

Every vehicle has a safety factor/margin built in. General rule is anything +/- 3% of the factory OEM tire diameter is acceptable tolerances.
So one size wider, one size taller, usually works fine.
The OEM 17" size is 205/50/17 a slightly wider and taller 215/50/17 should fit without issues even using the stock wheels and offset.
Something to consider. A larger tire takes more torque to turn. The Ecosport is no power wagon. Going to a taller, wider tire will likely result in a noticeable difference in performance. Either engine is taxes fairly hard just moving the vehicle around. Not a lot of extra power free and available.
A larger tire also effectively raises the gear ratio which would be equivalent to running a taller gear in the transmission. Lowering engine RPM and power at the same speed compared to the stock setup.
So now you have slightly taller gear ratio making less engine RPM and horsepower needing to turn a larger tire.
