Full size spare not the correct size

[MakinDoForNow]

Full size spare is just that, it’s not a donut you can drive 45mph max or whatever speed it says on the little donut that is only supposed to get you to the next exit and to a tire shop.

The full size spare is a full size tire that can be used for the rest of your trip. It’s not a matching wheel/tire combo it’s a 100 dollar drive for a week or two option until you have time to fix the tire which is nice to have especially if you are hauling or towing when you get a flat.

Now, I’m off the opinion it should be cheap and not worth stealing (steel wheel and cheapest non matching tire they can source) but it should be the same diameter. That’s where it doesn’t make sense to me, now if you have fwd and a flat on the front you need to move a good one from back to front and put the spare on the back.

Entry level vehicle, I’ll overlook it.

Has anyone checked the rolling radius of the spare tires (full size & donut size) when filled to their elevated recommended pressures to that of the regular tires on the ground at their recommended pressures?

Maybe someone will start screaming "class action lawsuit."

Those kinds of threads are always amusing.

If they did this on Wranglers it would actually matter.

vehicles not designed for off road applications or non 4X4 vehicles most often will not include an exact size match. And no, the FX4 option does not make this a 4x4 off road vehicle.

With any luck you’ll never need the spare.

You paid extra for a larger donut wheel. The Full Size Spare is "Not Full Size"!

It's like the foot long sub sandwich, it's not a full 12". I found this out just before I ordered my Maverick in November, as I was going to go for the full size spare, then I thought I have been driving for 42 years & have never had a flat on the road, so donut is fine for me.

If full-size spare doesn't mean the wheel and tire are the same, what would I call that then?

First, Ford was deceptive/lied about the full-size spare.

Then, they lied about the full-size spare being included in the Lariat Lux for Ecoboosts.

I'm running a Unique 83 steel wheel from Discount Tire for $100 and 245/65R17 tire.

Never had a flat? Wow! My CRZ came with a can of fix a flat. Ened up putting run flats on it. Lost a couple mpg but it came in handy.

Yes. This topic was discussed in excruciating detail last fall when people discovered the dimensions of the “full size spare“. Everything imaginable from precise measurements to technical review of dimension changes with velocity and inflation pressure have been posted. It got way more attention than it was worth.

I get this argument for the ecoboost people that paid for it as a add on. But for the hybrid people myself included. What is there to complain about, it’s what comes with the truck. It’s suppose to get you to safety not act like a replacement tire.

One has to wonder if this could lead to a lawsuit, Full size spare. Hmmmmm
Reading the paper or listening to some news it never ceases to amaze me what can be litigated.

Almost like ordering an adult meal full plate but you get a six inch diameter plate. See it's full.

I had a spare tire on my Chrysler Pacifica AWD that wasn't the same diameter as the rest. It literally blew up the transfer case at 50MPH because that wheel was rotating at a different RPM than the rest. Funny, when I contacted Chrysler they 'very quietly' paid for my entire transfer case replacement... (I think they knew). I'm not sure about how this AWD system works, but based on my experience I will not take that chance. FWIW. Fullsize spare w/correct tire for me.

With any luck you’ll never need the spare.

Or when you do need it..... your other tires will be worn down to the same rolling radius of the brand new spare.

A 12v compressor and some slime will get you out of most situations if changing is inconvenient
