HANKOOK VENTUS S1 NOBLE2   I have a set of four ( 4 ) of the above listed tires.   They only have 3,000 original miles on them.  Tires are in excellent / like-new condition.  I am the original owner.   Brand new today these tires are $323.99 for one ( 1 ) , per Tire Rack.  I will sell the set for $500 firm.   Of course, there is a catch.  I live in Mass. so you have to come to me.   If interested, please let me know  

I am going to presume you have a 2012 Ford Edge SE since you didn't expressly state the trim model.   Per Cooper Tire, your standard tire size for that car is 235/65 17.  Cooper offer the Endeavor Plus and the Endeavor Winter in that size.   Maybe the whole issue resolves around the current wheel / tire you have on the car, as they are over-sized from OEM standard.  The 245/50 20 is an optional size.  Per the Tire Rack reviews, the Endeavor Plus is rated " Excellent " in comfort.   When I bought my car, they came with 245/50 20 Hankook Ventus S1 Noble 2.  The comfort rating is lower than yours ( 8.0 ( me ) vs. 8.7 ( you ).  I found those tires too soft so I chose a different tire of the same size to meet my wants / desires.  Now I just have to find someone who wants them   Seems your initial plan of going back to 17 wheels / tires may be the best solution for you.

Yea for $75-100 I'd order a set to try. But not for $300.    When things are overpriced no one will buy it ($1500 downpipes, $12-1500 exhaust things like that). Crazy. 

I'm not normally a dealership guy, but I went there for the fluids. I almost fainted at the price of RDU oil, but it didn't take much.    Tips: the RDU is rubber mounted, you can pry it slightly to get acess to the fill plug. The PTU is pretty easy. Just a bit of automotive yoga to get to the fill plug.

The 17” wheels for the SE model of the 2012 Edge were the same 7.5” width.   https://www.wheel-size.com/size/ford/edge/2012/#trim-i-facelift-2011-2014-20-ecoboost--240-385   You linked to the next generation.

For the specific viscosity/weight of the oil in each part consult your owner's manual, then select a reputable brand such as AMSOIL, Redline, .......   Please add your Model & Year to your profile signature - Settings - Ford Edge Forum

Hi everyone. It's time to change the front and rear axle oil. I'd appreciate any advice on which oil to use for which axle. The internet offers varying specifications—75W for the RDU and 75W-85 for the PTU. I'm completely lost as to which to use, as other sources suggest 75W-140. My car is a 2023 Edge with AWD and a 2.0 EcoBoost engine. If you have any documentation for my car, including the oil specifications, I'd be grateful.

Introduction post.  Just saying hi. Just got new to me '14 Edge SEL 3.5 AWD. Sync 2 v3.10   Has 180k on it now but was fleet vehicle 90%of it's previous life with all maintenance done.  Just got forscan and enabled remote start and tried the navigation hack... Success with the remote start .. jury still out on the nav.

Thanks man. I have a 2019 Titanium 2.0. Do you need to physically take the vehicle somewhere for tuning? 

Good callout on the stop/start accumulator. The solenoid on mine wasn't loose, but the seals on the solenoid pooped the bed and puked fluid in my driveway. Easy to replace yourself.
