I decided to simplify & move the basic information that we learned about getting a larger than stock Spare Tire and Wheel. The objective was to get a spare tire that is as close to the 18" optional W/T as possible and still have it fit in the trunk. The humungous working Thread with all the Posts is seen here, this new Thread only has the final, workable solution I came up with. It may be done another way by someone else, this is only my version of getting the job done. Information about obtaining a Jack and Lug Wrench is in the other Thread. ======== Took long enough to get this project finished but now it's complete. The Foam Insert is out, the spare is in. The exact part numbers that I have on my receipt are: QTY - FP NUMBER DESCRIPTION 1 - CV6Z-1015-B T16" x 4" WHEEL ASSEMBLY 1 - 9002-0340377-000 T135/90R16 tire, Continental My Dealer mounted/balanced the bigger than stock Continental T135/90-16 spare tire on a T16x4T standard Fusion spare tire wheel (CV6Z1015B). 1. Does it fit in the trunk wheel well?' YES, exactly, with no room to spare (pun intended). 2. Is this larger spare tire/wheel the same size as the optional 18" wheel/tire on my car? Almost, this wheel/tire setup is only 1/2" difference in diameter. Note: The standard Fusion spare tire/wheel combo is over 2-1/2" smaller than my optional 18" tire/wheels. That is a huge difference in size. * Recommended tire pressure is noted on the sidewall of each brand tire. 3. How does it drive on the car? Pretty well, with hands off the steering wheel it drove straight. Again, stopping with hands off the steering wheel showed only a slight tug to the direction of the spare. The dealer tire tech and I drove around for about 10 minutes with speeds up to 50mph. Handling was acceptable, stops were easy, all was fine for a Temp Spare. I guess we didn't drive long enough because the TPMS light didn't come on, nor did any other dash alerts. Stowing the spare in the car: It's a snug fit, does not need the hold down screw. That's good because I stowed it inverted, so the inside of the wheel is up, allowing some storage. I was able to get a small air compressor, some road flares, jumper cables and funnel to nestle in there, all level and flat. Where to stow the Jack/Lug Wrench combo? I did it this way and it works just fine. Edit: What Jack to use? The Jack can be purchased from the Ford Parts counter, just use the standard 2013 non-hybrid Fusion Jack/Lug Wrench Combo for reference. The integrated Lug Wrench is a standard 3/4" model. They were also used in other Ford vehicles (i.e., earlier Fusions) and can be acquired used from auction sites if you know what to look for. Where I got my Jack Kit, a picture of it, from what used car it came from and use of the Jack/Lug wrench combo is here. Edit: This picture is not current. I have since removed the bulky TMK and added some other tools, smaller air compressor & other helpful items.

Hi, I wanted to share my experience with replacing the tire mobility kit with a doughnut spare tire in my Ford Fusion Hybrid SE 2014 (17 inch wheels) in particular what to look out for in case others are thinking of doing the same. I've included a lot of details for those like myself who do not know a lot about cars and are learning this stuff for the first time. I've sustained side wall damage several times on my Fusion. The tire mobility kit did not work for side wall damage and even ruined my tire pressure monitoring sensor on one occasion. I decided it was time to get a spare tire (which the car did not come with). Pricing The dealer I called (I am in California) was quoting the wheel for $207.95 (without the tire which they did not stock), jack $139, lug wrench $37 and foam insert $54. The tire can be purchased online for $158. Total $585.95. I called my local auto wreaker - they had the wheel and tire, jack, foam insert and wrench and quoted me $150 - $200. I have also seen the wheel and jack sold together and separately on eBay for a range of prices. Important information I did my research on this forum (thank you for the wonderful wealth of information) and looked at my friend's Fusion spare tire setup. Here are the important things to know if you decide to go the secondhand route: 1. The wheel you want to get will have CM5C-1015-CXA engraved on the wheel (the part number is CV6Z1015B but this is not printed anywhere on the wheel). 2. The tire on the wheel is Maxxis T125/80R16 3. I recommend getting the jack (which should have a slim metal stick that moves the jack up and down attached), the lug wrench and the foam insert (see pic from my friends car). The foam insert with all the parts will sit nicely inside the tire. 4. The Fusion comes with a lock nut holder (spindle) which holds down the foam insert. This spindle also works to hold down the spare tire and foam insert. 5. I recommend installing the doughnut onto your car before you buy if you have the time - that way you can test if the jack works and the tire fits. I am glad we did this as the first tire the auto wreaker gave us was 16 inches but did not have CM5C-1015-CXA engraved onto it and the tire was a Maxxis T145/80D16. It sat too high in the trunk (as it was wider) and the holes on the wheel would not line up with bolts on the car. It would have sucked to be out in the middle of nowhere 2 years later with a flat only to find it didn't fit and the tire wasn't returnable! Fit To fit the tire in the trunk 1. Lift up the trunk floor carpet/liner 2. Unscrew the spindle holding down the foam insert (which holds the tire mobility kit) 3. Remove the foam insert 4. Put down the newly purchased foam insert containing the jack and lug wrench (jack side up). The bottom of the foam should have a rectangle divot cut out which sits over a small rectangle of metal on the trunk floor. 5. Put the wheel in, outer edge up. The jack and insert should sit nicely inside the wheel 6. Screw the setup down with the spindle (see picture) 7. Replace the trunk floor carpet - it should sit flat. The tire mobility kit will not fit under the carpet but I keep it in the trunk as the compressor may come in handy. Here is a post from another member detailing their experience driving on the doughnut Here is post from another member discussing how to make the spare work for 18 inch wheels. Hope this helps!

To start with you should use the door sticker and then pay attention to tire wear. If it shows more wear on the edges of the tire it is under inflated. All FFH/CMAX I have tested show signs of under inflation at 35/38 psi. I asked My FORD Service Mgr to ask FORD about tire pressures and he got a no comment. ;( I did talk to Tire Rack tire testers and they said that it is common for FORD to under inflate their tires to get a little softer ride, tire pressures are a compromise between ride quality, gas mileage, handling and stopping among other things. The FFH/ CMAX have 35/38 psi recommended which is odd for two FORD cars that weight the same and have similar suspension. It would appear that ride quality/ smoothness is high on their priority list. Talking to Michelin Rep they recommend starting with FORD's recommended pressure and then find the pressure that gives even tire wear. I told him I was using 50 psi and getting even tire wear. He Said "Then he wouldn't have problem with that and not to exceed 51 Cold tire pressure" BTW the bursting pressure is around 200 psi , so you don't have to worry about that. An auto mechanic on CMAX forum used 55 psi with no problems, but I wouldn't recommend this. I did look at a number of used FFH in Dealers lots and sure enough the tires were wearing more on the edges than the center which is a sign of under inflation. So it is obvious 35 psi is to low to get even tire wear. Facts: FFH/CMAX can use 35/38 psi to 51 psi from OM and on the sidewall of Michelin ES safely according to the Michelin. With 220k miles of experience my tires last longer and perform better than they did at 38 psi and get better gas mileage +1.3 mpg at 50 psi. My last set of Michelin Energy Savers lasted 87k miles, only warrantied for 55k miles. The nice thing about tire pressure is you can raise it up and try it out and then decide what to do next, you can always go back. :) Note: Tires aren't very sensitive to pressure, if you go up to 40 psi you will probably not notice a difference. At 45 psi you will notice a little difference and 50 psi a little more. Also Your tire pressure should change with Gross Vehicle Weight . There is no info in OM about changing tire pressure unfortunately. ;( For me I have saved about $500 going to 50 psi tire pressure by improved mpg's and tires lasting 25% longer. 50 psi does make for a little stiffer ride and I think all the improvements in performance, gas mileage, tire longevity and 1/4" increase in ground clearance is definitely worth it . :) You should have a tire pressure gauge and tread depth indicator in your car so you can monitor the pressure when you put air in your tires and also measure tread often to see how the tires are wearing. I use these to measure FFH/CMAX tire wear also have digital tire pressure gauge too. Paul

Found a great, light-weight box measuring 35"X18"X6.5" online at 'The container store' and with a 24" flat bungee cord from 'Home Depot', I got all my stuff up above the HVB shelf and out of the way... After being upset for a while for not having a spare tire, I realized that actually, it's better this way. In 40+ years of driving, I can count on two fingers the times I had to change a tire on the side of the road. Usually what happens is a nail that would cause a slow leak, giving me plenty of time and driving distance to take care of it without using the spare. Why lug around a 20-30 Lb. spare for the next 10 years if the odds of needing it are so small. I do carry a jack and a repair kit but hope I never have to use them...

I know there have been several threads pertaining to using a real spare in the Fusion Hybrids, but I'm concentrating on the use of Ford's actual Mobility Kit. I've heard rumors that using the can of sealant that Ford provides causes loss of your TPMS sensor. People have sworn this is the case; however, I went to my dealer Service Department and they told me that Ford would warrant the TPMS and replace it if anything like that happened due to use of the Ford provided product. Wal-mart sells Fix-A-Flat that is marked "Safe for TPMS" sensors, but that's not what Ford is using evidently. Has anyone had the opportunity to have to use the Mobility Kit yet? What happened?

I recently had all four tires replace and unfortunately did not look closely after picking up vehicle. I have now discovered that the tire dealership put on Continental Pro Contact P215/50R17 instead of the Continental Pure Contact P225/50R17. My main question is in regards to the tire size 215 vs. 225 does this pose a safety hazard and if not what concerns should I have? Regards, Steven
