21" Edge ST wheels installed on BAP Alto Blue Hybrid

[InDaRed2]

Picked up some 21" Edge ST wheels/tires for a steal off facebook marketplace last week. Tires are 265/40R21 Continental cross contact LX sports. 2 are in good shape/almost new but 2 will need replaced soon.

As others have mentioned, with these wheels a spacer is needed in the rear to add clearance to the fuel filler neck/wheel well liner area as shown in the pic below. Used a 1/4" spacer off amazon.

Look pretty good at stock height but will look even better when i get around to adding the Eibach lowering springs. Fuel mileage took a decent hit from what i can tell so far, down about 5mpg but havent driven much yet.

Very nice! That’s spot on with the reduction in fuel economy that I saw with the same wheels/tire size.

Looks good, thanks for the pics and the info on MPG loss. That would be my biggest concern.

Why would the fuel mileage be reduced ... rolling on larger diameter wheels? Wheels go 'round and round" the same ...

Larger diameter will equate to a longer distance (roll-out) covered per every revolution, so if the speedo/odo do not "recalibrate" then the truck will think it travels LESS than it actually did.

Another person said they installed larger wheels, and found their Maverick "re-calibrated" to the larger diameter, as both the truck's speedo/odo and a separate GPS speedo were identical.

- The idea being, the vehicle companies KNOW that dudes (almost always 'dudes' ... not chicks) are changing wheels/tires ...and for those vehicles equipped with GPS (think shark fin/etc) ... easy to have the software re-calibrate the speedo/odo. Keeps the vehicle within the warranty aspects the manufacturers are responsible for ... .

Torque

I can't say for today, but back in "my day" F1 cars used 13-inch wheels ... (and we'll not get into the limits of wheel bearing speed, although rest assured all that is well calculated, ensured) ... not one ever saw a race car that didn't have a gang of mechanics working on it all the time !!

SO, who that have changed their OEM wheel diameters (effective rolling radius) have retained a speedo/odo difference over, say, a number of miles?

Or, have those with the software ... found and changed the wheel diameter settings ?

Larger wheels reduce rolling resistance and in the case of these wheels, they are much heavier than the factory wheels. I noticed a loss as soon as I installed them.

As far as the speedo, I’ve typically found that the reading on the dash is 2-3 mph higher than actual/GPS. When I installed these wheels, the dash was closer to actual/GPS. It does not auto calibrate.

Looks good.

Do you have a link to the spacers? I’m thinking of doing the same rims.

Cheers

Mave-Rick was kind enough to provide the spacers he used. I purchased the same ones. 6mm used on rear only.

Tires are taller, wider and heavier. Wheels are heavier. Added rolling resistance and power needed to account for the taller/wider wheel equals less mpg...

 

[TheMaverickLife]

Oh, heavier wheel/tire combo ... yep, will make a difference.

That would then make the 19" forged and the 18" ... wheels I'm offering a good choice for those seeking both style/look and less weight. Also, last I bought tires, the larger the diameter, the more they cost. Must be the "expense" of making a tire is in the "bead" ... so the larger the bead, the more the cost verse the width (when compared across sizes).

the best color ever offered IMO..

well now you have room for a brake upgrade

I agree with you. People talk about weight? So if you're 150lb guy, are you going to have lower mpg if your 250lb ?? I don't think you would notice any change. I put 21" rims on mine , and maybe noticed 1mpg. But winter gas is different then summer gas. And warming up in the cold months. Just my thoughts.

Rotating mass is roughly three times harder to accelerate than sprung weight. This means that dropping just 10 pounds per wheel with the addition of a lighter set of racing-oriented wheels would equate to a reduction of almost 120 pounds of sprung weight. Obviously, heavier wheels do the opposite. I tracked several tanks before and after and also lost about 5-6 mpg

Agree, wish I could go back and order it in that color.
