Ladies size spare

Good point. I’ll show her the lsd button.

 

Make sure she knows it needs to be a long press.

 

Like previously said: Roadside Assistance.

And, as also mentioned: roadside tire replacement is a non-starter. Get off the road. A wheel is cheaper than an extended hospital stay...or worse.

 

I've got a 255/75 17 on a FJ spare rim as a spare for my 285/70 17 SCS F5's. It's two inches narrower and just a little smaller in diameter. It's nice because it doesn't hang down as far when it's stowed underneath.
There's also a trick where you take the tire iron and put it on the ground, roll the spare onto it, and then use it as a lever to lift the spare. It makes it a lot easier to get it up onto the hub

 

Gonna blow out the differential with differential size tires. Get a 33 as spare and AAA roadside assistance, I'm sure a HD 100lb jack is need ed to lift the truck high enough for tire to be removed

 

If she can do all of the other stuff (particularly loosen the lugs), then she should have no problem lifting the spare onto the lugs; it'll just take some practice.

I'll sit on the ground cross-legged, or with my feet on either side of the tire, and basically bear hug the tire to lift it up, easy-peasy. (And I'm likely smaller than 95% of folks on this site). You can use your legs to help lift / stabilize it as you get the first hole lined up.

Agree with everyone else that deliberately mismatching spares is asking for trouble, and that roadside assistance is super cheap for what it's worth.

Or, if she's only ever 50 km away, why don't you go and change the tire for her?

 

Seems a lot simpler to just go back to a sensible stock tire?

 

If it were my daughter or wife I would use roadside assistance. Many Ins policies have this for no or low charge. No charge on my GEICO Policy... My wife has used them several times.

 

Possibly but reliability of these services has been spotty for my wife.

thinking 235/85R16 or 255/85R16 on Lightweight 16” or 17” steel wheel (possibly a thinner 6–7” wide rim)

 

How about a standard (matching) size spare, and two custom-cut wooden wedges, made from 4x6 or 6x6 stock.

Once the truck is jacked up and the tire is 1/2" to 1" off the ground, put a wooden wedge on either side of the tire to be changed. The wedges will support the weight of the tire when it is pulled off the lugs.

For putting the spare on, remove one wedge, roll the tire into approximate position, then put the wedge back and "walk" the tire up the 2 wedges and forward onto the lugs. (Moving the two wedges to bring them slightly closer together as the tire is rolled back and forth between them, which will raise the tire in very small & easy increments of maybe 1/8" or so.)

Practice 6 or 8 times on a flat parking lot or driveway somewhere to get the hang of it.

 

That and people get target fixation and just plow right into stopped vehicles on the shoulder.

I had to pull off the side of the highway to yank a massive tarp some jackass lost from an unsecured load that wedged under my bumper and traffic zooming by was sketchy.

 

Helium filled tars

 

I don't keep it in my truck so it's not much use for on the side of the road, but I have that exact dolly for such application. Sedan tires are not that bad, but for the taco and cross overs it's a back saver for tire rotations and seasonal change overs.
I set my impact and a magnetic tray on one end of a creeper then kneel on the creeper and press the lever with my hand if I need to raise the tire a bit more.
I carry an 8"x8"x2" block of wood in the truck that I can use as a jack base on sketch ground and add some height because I'm slightly lifted. As others suggested it could be used to raise a tire to line up the lugs.

 

I don’t think roadside assistance is all that great. Had to wait 5 hours.

I deal with extremely heavy wheels at work. I found a felling wedge at Home Depot. I use it for a little ramp to get it onto a board. Then use thicker and thicker boards with the wedge in combination with a pry bar strategically placed. Then lift into place. Or sometimes I’ll put soapy water under the wheel, then lower the jack to just the right height, then slide it into place. Yes I have blocks for in case the jack falls.

 

If you are that worried about weight, why not a aluminum wheel.

 

You need the spare tire to match the diameter of the other 3 tires. Cant get around that.

She'll have to remove the 33 wheel anyway..this whole scenario really makes no sense....a 235/85/R16 only comes in E load and weighs 39lbs just the rubber, fyi.

Buy her a gym membership instead or/and tell her to get a boyfriend. Being self sufficient is a good thing.

 

Trade her in for a boy

I am gonna pile on the roadside assistance bandwagon..

I am fully capable of changing my tires, done it at home a few times when I had a flat..
What I will not do, is do that on the side of the road [way too dangerous] - and even in a parking lot, it can get sketchy

Think of all the rando creepy dudes that will come up and want to "help"
Sure, there might be a good one in that mix but for my own safety, no


Add in that doing this is harder when you are under stress and don't have the right tools . . .
Break the lugs without an impact for example - -


If she isn't gonna be that far from home, she could always pull into the nearest lot and call you for help if you really don't wanna do the roadside assist thing.

 

Something to add. The “tools” that come with the car border worthless. Not all shops torque the lugs. Some still slam them on with an impact. Getting them off can be challenging. More so with the silly lug wrench. If there’s one that won’t come loose, it’s always the last one, tighten the other one’s back up, then try that one difficult one.

My grandfather’s car had a lug nut that refused to come off. It just spun and spun. I think some shop cross threaded and forced it tight. So I had to spin it about 300 times until it got super hot and finally broke off. Replaced the stud & lug nut.
