Weight of the stock 22" wheels and tires?

[daved1992]

Im just wondering if it would be beneficial to throw on some aftermarket 22's in terms of weight. If these are heavy, I'd get better mpg and performance.

I would not get 22s unless you just HAVE to have big wheels Dave. Why you ask?

 

I have a 2010 Edge "SPORT". (Which b/t/w I do not recommend the sport edition) with 45000 miles (yes I drive a lot)

I have yet to get better than 20-MPG highway, city or a mix of both, though my commute is 60 miles every day, and I average 19 MPG.

One caveat: I have done some research and have discovered that huge wheels/tires do cost fuel economy. The rotational inertia and cross sectional area take energy to get them put into motion (in this case the energy is spelled 87 octane fuel) and to change the rotational speed takes energy as well (IE accelerate). Unfortunately the Sport edition has huge wheels/tires! ^:- (

 

??: Does anyone notice that to get their Edge to accelerate when at highway speeds(70-75), especially if in overdrive, that you have to depress the accelerator enough to get the transmission to shift down about 2 gears or so and bring the RPM up to about 3K before their Edge will speed up? (This could be another cause/repercussion of the 22" wheels)

I have also noticed like "KYEDGE" that the Ford Edge is very speed sensitive in relation to MPG. 65 does seem to be the top of the 'sweet' spot, with anything over that speed (at least in the doggy 'SPORT' edition) causing MPG to drop off rapidly. With the cruise control set at 75-80 MPH, (yes, of course I'm in a state with 75 MPH speed limit) my MPG is barely 19. Also, If you have ANY head wind...MPG can easily drop to 17 and I have once gotten 15.5 with a strong head wind! I know that Ford has realized they made a "dog" in the 2010 Edge Sport edition, and they have attempted to fixed the problem for 2011 with 3.7 liter 300+ horsepower engine, but that does not help me one bit since I have a 2010. My next move is to get ride of those 22" mamba wheels that the Sport edition comes with and get much smaller/lower frontal area 18 or 17" wheels. Especially as it looks like we will be staring $4.00 a gallon gas in the face very soon now! (Oh, also, those big 22" tires are have a soft compound rubber and look to only last about 50,000 miles. WAIT till you price out replacement tires for the Sport edition! Yikes....$250 a tire is cheap!)

 

?? So, does anyone know if 5 bolt ford explorer wheels fit an Edge? I can get a good deal on a set of 4 that look very similar to the Edge 18" wheels.

 

Thx

Ford and other makes screwed themselves by this move to unique size tires and very large wheels. The tire venders could not supply enough of these uniques sizes and so Ford actually had to cut back production of certain models at the very time that they could have picked up salse due to the loss of product from Japan.

 

These unique tire sizes limit our choices when it comes to replacement tires and the the price seems to reflect that fact. Good old 16 inch wheels in a standard size might not look as cool but the benefits are obvious; lower cost, greater consumer choice, better ride, better performance, far less weight.

 

With the demands for better fuel economy coming fast, one would think that the days of these very heavy tire/wheel combinations are limited.

im running the oem 17" tire and i usually get around 21-24mpg mixed driving... i had been contemplating going with a larger tire like a 20 or 22 but when i heard that my MPG will be going down i decided not too... dont get me wrong they look bad ass but not sure if its worth the decrease in MPG....
