Get rid of that useless, dangerous standard emergency mini spare tire. Now!

[surprisinguy]

Has anybody done this on the staggered setup?

You'll have no problem running that wheel on the rear

 

[Starflyer]

That's so useless! I can't even drive 300 miles at 75mph on that 1 gallon of gasoline!

AND why would you want to? Especially at 75 MPH?

AND why would you want to? Especially at 75 MPH?

Probably for the same reason you would WANT to drive on a donut for a week or two at highway speeds??

I guess it wasn't obvious that that was sarcasm.

My advice is to either buy your car with a full size spare, or get one ASAP from another source.

I don't know for sure but I think the reason the Donut spare even exist is because of bean counters, wanting to keep the cost of a car as low as possible. Probably save as much or more than $100-$150 by equipping new cars with a donut spare. Also reduces the weight of the car and maybe adds 1/50 of a mpg to the EPA estimated gas mileage.

Back in the days when cars came with a full sized spare tire on a matching alloy rim I would rotate all 5 tires to get more life out of the original tires. I would then purchase 4 new tires while keeping the best one for the spare. Then some manufacturers began including a full sized spare on a non-matching steel wheel. This regulated the spare to an emergency only tire. The next money saving step then became the temporary spare as we have today. The final money saving idea was to eliminate the spare tire completely and just include a can of slime fix a flat. I think that I would buy a matching factory alloy wheel if I didn’t have a staggered setup.

I'm knocking on wood as hard as I can, almost pounding. But I've never gotten a flat, neither a blow out nor a nail/leak. My wife once had a nail in her tire about 3 weeks into owning it, extremely slow leak, maybe losing 1.5 psi a day. The dealership replaced it under some warranty package.

You are fortunate, keep pounding that wood. I've had a couple of flats over the years, usually not a big deal, but not long ago I lost two tires to cut sidewalls. Neither a spare or slime helps in that case.

Closest I came was many years ago, hitting a pothole that was hidden by snow/slush. Sounded like the strut came through the body. The jolt actually caused pain in my spine. It broke a belt on the inside of the tire, I never knew until I got the tire replaced the next year due to wear. There was a big bubble on the sidewall. I only put 2 and 2 together to realize it had to have broken in that moment. But I drove it the rest of the year with no pressure loss, boy am I lucky. At the time, I was driving 70 miles of interstate a day for work.

I totally get it (the last 2 posts). But still missing the point a little. It's a donut. Nobody should be shocked by that. And EVERYONE here knows what a donut is for. It's meant to get you "slowly" to a shop. It's not the donut's fault that tire shops aren't close enough, or that they're out of stock. And It doesn't matter if you're 300 miles from home. The donut isn't necessarily meant to get you back home. Unless you have spare tires at home and the machinery to mount them.

The point I'm trying to make is that a donut is surely NOT "useless" ever, or "dangerous" when used as intended.

Imagine having a spare gas can in your trunk in case you run out of gas, and then complaining that it ONLY holds 1 gallon!!! That's so useless! I can't even drive 300 miles at 75mph on that 1 gallon of gasoline!

Idiotic to think much less say that donut spares are dangerous or useless.

I've used "donut's" several times in my life. When I have on the car I drive 40 mph max and STAY off the Interstate highways. One time while out in the sticks I had to drive 70 miles to the nearest tire shop, sweating the whole way that the donut held up. AND IT DID! I think the most important thing about donuts is to make sure they're inflated to the recommended pressure.

Then again, at least on my base G80, I can get a matching OEM wheel and mounted tire "in good shape" shipped to my door for $200. Not bad to have if I were to be driving a lot in rural areas. Cheap insurance, and it'll fit in the same spot. I can also sell my donut spare for about the same.

Last week I had a flat that could not be repaired on my 2017 G80.

I had to drive around for 3 days on that emergency mini spare that came with my car. DANGEROUS AS ALL GET OUT.

Warnings on the tire and mfrs web site basically say, UNSAFE FOR MORE THAN A TOTAL OF 50 MILES...UNSAFE AT MORE THAN 50 MPH...UNSAFE WITH A FULLY LOADED CAR, UNSAFE, UNSAFE, UNSAFE!

After replacing all 4 tires, I spent a.total of $100 to buy a full size wheel from tire rack.com and had one of my old tires mounted and balanced on it. (Wheel was $75 and mounting it cost $25).

I sold the old mini spare for a few bucks, and now have a good spare tire I can drive at speed, under a full load, for thousands of miles, and not loose sleep over the safety of driving on a spare.

PS. I felt it was best to replace all four tires rather than drive around on one brand new tire and three old ones with about 1/3rd their tread life remaining.

My advice is to either buy your car with a full size spare, or get one ASAP from another source.

It's not expensive for your $50k car, and it could save your life and the lives of your passengers, too.

I did the same thing with a full size spare for my 2016 Genesis 3.8 sedan. I am now trading this car in for a 2022 G80, that has a donut. I am not sure if the front and rear tires are the same. I think they are different sizes. If so, how do you guess what full size spare tire do you put on a rim?

Use the smaller of the two sizes, the front size.

thanks

Here is my full size spare. It took a while to come up with a 19" rim. I wrapped the tools up in a rubber pancho. No rattling sounds. The black cloth bag is a small air compressor. The only downside is the tire is a lot heavier than the donut. Makes getting it out of the trunk hard.




The floor panel for the trunk fits flat like it is supposed to.


The styrofoam tool holder went into the storage room along with the donut.

Hopefully, I'll never need it. However, if I have a flat, I won't be sweating bullets about the donut.

$75 for a new wheel? Wow!

 

[MorrisGray]

I agree, those donut tires ARE dangerous. I bought an OEM wheel ($225) and put a Michelin CrossClimate tire ($235, like the other 4 on the ground) on it and it fit perfectly in the space. I did the same with the tools as you did.

Where did you get the OEM wheel from?

 

[TinsleyC]

Where?

They are on eBay.
