So anywone try removing their spare tire to lighten the load and improve their MPGs?

My 2013 Ford Focus ST came with a full size spare. I was thinking just for the daily commute. I would put it back in if I am taking a road trip somewhere.

I have AAA road service so if I got a flat I would call them up and they would tow the car home. (under 100 miles is free tow)

I would not do that for the meager savings I would get.

"The traditional spare tire has been replaced with a can of fix a flat in these vehicles."

Good luck on fixing a wall slit or a large puncture with that stuff. Fix-a-flat is a joke.

Years ago I've found that "Any kind of Weight" removed does benefit mileage. I once removed a complete truck bed, and still drove that truck for a month bedless. The vehicle actually felt like the engine had gained nearly 75 extra horsepower! Peppy! Real peppy!

The main problem was the truck became too light in the rear section, causing spin-outs and skids on wet/dry pavement with that much weight removed, also the front to rear balance was a stability handling problem.

Human "Spare Tires" weight counts into the make-up of the total drivable cost factor weight. Removing my truck bed also caused Me to lose sleep.....

How about the driver losing the spare tire or beer belly (body fat weight)?

There are some drivers that realize that removing any type of weight from a vehicle then will naturally reduce cost of energy used to propel that vehicle.

The tricky part not always realized, and then the reduced cost is not a quick happening to be noticed. Reduced weight is in effect but often the benefit action is controlled by the Driver's environment/use of each vehicle.

Driving up/down any grades, driving in stop/go traffic, resuming back up to speed/quick acceleration, all these factors plus how many times over a given/monitored time interval, Repeats of these conditions, these all add cost when repeated, then realized.

The tricky part is the more active times that these mentioned factors become common occurances, then the vehicle weight plus/minus factor by any lbs. factor determines the savings gained or lost.

The other factor that comes into play heavily, is any low inflated tire/tires noticed or not, at any speed, also this factor only joins up with the amount of vehicle total weight in motion factor gets compounded for more loss.

The OEMs know all this, the tricky part, when they design lighter vehicles for economy operation. Drivers/owners often overlook the tricky part by sticking with their less thought habits or don't want to be bothered by the savings concentration thoughts it seems.... or puzzled by how the weight factors combine with the others involved with motion..... HAGDay!

It's nice to have four close family members owning portable 12.5 volt tire air compressors handy, and jump cables, dozens to say the least. Save some fuel by less weight put that partial amount for troubles expense in the Kitty Box, Share.... There are such things as Cell phones, Call Talk..... it's a trend.....

Everybody Happy, use Kitty money to buy extra wise stuff at Christmas time, may even a Roll-off vehicle, train the Grandchildren....

If gas mileage was so important in the first place, than you should od bought a PRIUS or VOLT instead! Never ride without a spare, just jumb waiting on someone else to help me.

I'd rather have the tire than the fuel economy I would gain. I've gotten flats, and the spare has saved my ass.

My experience is, there is no quick way a fuel savings will be noticed, by removing only a few lbs. of vehicle weight. The amount of stops/start-offs of vehicle motion(Inertia force law) that stays in effect which builds up doing city driving then over a longer time interval. A lot of other factors are involved. Like anything you must do as a driver while in vehicle motion.

That use (Stop/start motion) x the extra engine energy force(extra fuel needed) to overcome each start motion or resume to a high speed becomes extra cost. The weight factor is the additive of more/less fuel energy cost needed for staying in motion. Stops cause repeats of added fuel cost.

Less weight involved each time cuts the fuel energy needed along with the amount of times one goes against the Inertia Force(enacted)barrier.

Simple is >>>> steady motion speed is more economical along with reduced stopping no matter what you drive toward the Engine turn-off event....LOL!

"It won't save gas, and this sounds like something only a rookie would do."

Between 10% and 20% of new cars sold in the U.S. do not come with a spare.
The OEMs claim it lowers the cost of the vehicle and reduces weight to save fuel.
So how do you figure GM, ford, Honda, Toyota, Hyundai are rookies and don't know how to increase fuel economy on their vehicles?

Idiotic...& normally AAA (here its CAA) sends someone to assist first...ie. expects if tire issue to change the tire. Towing is the last option & may charge if reason for tow is stupidity!!!
Should have spare tire of some sort or cans of tire fix + a pump OR run-flats.

I guess if you're literally NEVER going to use it and can be 100% certain of it, then remove it. I wouldn't though as I don't have AAA and don't pay people to do anything I can do myself.

I do run my wagon completely empty when possible though. The only thing in the back right now is a trash bag. Better take it out to get .000000000000000000000000000000000000000001 more mpgs.

My daily driven vehicle is over 14+ years old and never had the pressure in it's spare been checked or had it been mounted, never worry about it, fret or even consider, but knowing it's there hidden where it's supposed to be.

Geesh! look how much I could have saved in city driving over that time interval of 80 K miles 80/20 most city...... Never even weighed it! Along with the less weight of 1/2 tank of fuel most often then added to a spare full size at that = another Geesh in reduced vehicle weight. Say 90# +/-.

Missed out on that advantage in saving fuel out my tailpipe, along with the wrinkle worries, 14 years of them, before owning a cell phone even back then. Yikes!!

No I save gas by coasting up to stop signs and lights as my old Buick sort of freewheels. I think I save more by doing that than ditching the undersized spare. That spare has been used probably once in the last twenty years.

I remember seeing at least three of the same vehicles each time over 60 days running the skinny spare one on the rear, the other two cars had that type spare on the front, and were seen in my local fast food restaurant where I enjoy coffee at times.

Lots of stuck vehicles lately, frozen plow slush and ice covered ruts, Plenty most places, that wastes gas in town on the side streets, I avoid those and go the longer way around using less energy effort.

"I believe common sense is dead these days and this topic is proof of that..................."

Most of the OEMs have a line of cars that do not leave the factory with a spare. The traditional spare tire has been replaced with a can of fix a flat in these vehicles.
Its been going on since 2008.

"Wondering how long are those skinny spare wheels good for daily use, meaning months"

No where even close to that.
If you read the insturctions the "doughnut" spares from most OEMs say to only use the spare for driving no more than 50 miles at 50mph or less.
They are only intended to get you to the next service station that can fix your flat or sell you another tire.

No. Take the weight of the tire divided by the weight of the car. That percentage times your gas mileage is what you will save. You won't even notice it.

Yey The crew to your rescue if you don't have a spare then might pump you flat tire up with evaporated milk, then be on your way to the nearest tire shop. (Old school tricks)of yesterday worked on radiator leaks (poor man's edge) little smelly though for days.... Wondering how long are those skinny spare wheels good for daily use, meaning months....? Maybe?

AAA usually put your spare on your vehicle from your trunk...........

I can't see AAA towing you for a flat tire...........

I belong to CAA the Canadian version of AAA and they would only change your space not tow you because you have no space..............
