What is the small spare tire called?
While a few vehicles may come with a full-size spare tire, most come with a thin, fragile tire popularly called a 'donut.
Once car companies quit putting regular wheels and tires for a spare, they were called donuts. It is a derogatory term for the spare, because it was a cheap set up that wasn't totally functional.
What is a Donut Tire? Like a spare tire, a donut tire is a replacement tire that is stored inside your vehicle in case you get a flat tire and need to replace it. Unlike a regular spare tire, though, a donut tire is actually smaller than the regular tires on your vehicle in order to fit into your trunk.
A general rule of thumb is to drive no farther than 70 miles and no faster than 50 miles per hour before replacing your donut with a new tire.
A compact (or donut) spare is a lightweight, special purpose tire that's meant to save the day when one of your everyday tires calls it quits. The biggest advantage to using a compact spare is in the name: it's compact! You don't need to devote an excess amount of trunk space to it and it won't weigh your car down.
There are two types available: full-size and compact. A full-size is essentially another tire for your vehicle that you can leave on. It serves as a permanent fix. Compact spares are more common, and they are only meant to be temporary.
However, they are also much more expensive – temporary spare tires cost from $50 to $300. In the end, it's your choice.
These are called space-savers or donut tyres. They have a smaller profile than the usual spare tyres and hence, are lighter in weight and save a lot of space.
Can I Put Air In A Donut? You can put air in this type of spare one. According to the standard, the pressure in this type of product should be 60 PSI.
Donut tires, also known as temporary use spare tires or TUSTs, are great for saving space. However, just like with regular spares, donut tires do not fit all cars. They're mainly used as a temporary solution when you have a flat. Eventually, you will have to replace these with your regular tires.
Can my car sit on a donut?
The vehicle should be okay as long as it is not driven. The temporary spare is designed to go only 50 miles. It does not have any time limit but only a mileage limit. It may need to be replaced when it's exposed and gets cracks from sitting for a long period of time but it should be okay for a few months.
How Long Can You Use the Temporary Spare Tire? You should only use the temporary spare tire for emergencies. If you use the spare tire for too long, there is a good chance it will end up flat. In fact, you should only use the spare to drive for about 50 miles at most.
If you have a donut on your vehicle, swap it out with a full-size tire within 50 to 60 miles and replace the spare, Paul said. Full-size spares can be used for a longer time, since they match what's already on the vehicle. But Paul said he'd still take the spare off as soon as possible.
Spare wheel, space saver or tyre repair kit? | The Car People
What happens if you drive on donuts too long? The bursts or damage to the engine equipment, including the transmission, will happen if you drive too long with a spare one. It is not suitable for long-term use, too much abuse will endanger your safety.
A doughnut or compact spare is a short use, temporary spare tire. Generally, much smaller than a regular tire, doughnuts are meant for travelling short distances and at lower speeds. Essentially, a doughnut is intended to get you to the tire shop, and that's it.
Ruins Transmission
You know doing donuts ruins the drivetrain and, consequently, the transmission. However, this kind of damage warrants a section all to itself. If you happen to gain traction while spinning around out there, it could shift the gears or cause them to fail.
The driver simply had to clamp it to the rim of the wheel that had a flat. Davies teamed up with his brother and they were soon in business. They called their invention, the Stepney Spare Wheel, after the location of their workshop in Stepney Street*, Llanelli, Wales.
Also known as 'temporary use' spare tyres, space saver tyres are specially constructed spare tyres and rim combinations provided by vehicle manufacturers as standard equipment in many vehicles. These spare tyres are lighter and smaller than those which you would normally see fitted to motor vehicles.
Expandable/inflatable spare tires are available in some vehicles, including Porsche, Audi, Volkswagen, Mercedes, and Ferrari models. These spares come with a non-inflated tire mounted to the rim and an air compressor. Once you inflate and install the spare, it's ready to get you to the nearest Les Schwab.
When should I replace my donut spare tire?
Temporary, 'donut' spares are only safe to travel about 50 miles before needing to be replaced. After that, they can become a danger to you and other motorists. Full-sized spare tires can be driven for longer.
Can you use a smaller wheel as a spare? The short answer is yes. If you think about it, space saver spare wheels frequently have a smaller diameter than regular wheels. For emergencies, using a smaller wheel to get you home or to a tyre repairer is fine.

Over the past decade, more and more car manufacturers have ditched conventional spare wheels for tyre repair kits. They cite two main reasons for this: repair kits take up less space and are lighter, thus aiding fuel economy. But there's a third reason: cost.
DIY spare. Another option is to install your own full-size spare. You can order another full-size wheel and tire from a dealership or hit up used or refurbished wheels online. Even cheaper, visit your local salvage yard if your vehicle is a decade or two old.
Usually, the maximum speed you can drive on a space saver wheel is 50mph, and although there is no official restriction on the distance you can travel using one, around 50 miles is generally deemed to be the maximum safe distance for usage.
Compact Temporary Spare
It's smaller than both standard and temporary spare tyres, making it ideal for cars with smaller boot space, and requires a higher inflation pressure – generally 60 psi.
Check your donut tire pressure: The safe air pressure recommended for the donut tire is 60 pounds per square inch (psi). Since the donut tire sits for a while without being inspected, it is a good idea to check the air once you put the tire on your car.
The most common trigger for the warning light is low pressure in the vehicle's spare tire. Most customers are unaware that their spare tire also comes equipped with a tire pressure monitor, and the TPMS is only installed on full-sized spares, not donut spares.
Can you drive with a donut on the front?
What If You Have No Other Options—Can You Use a Front Spare? If you have absolutely no other options, and you're only driving a short distance (only a few blocks), then you're usually safe attaching a front spare tire—just make sure you drive defensively and refrain from taking any further risks.
Yes, as long as you have the same star or lug pattern.
A Spare Tire is no Spare Without Enough Air
Since tires require inflation pressure to provide load capacity, if any of these tires had been placed into service without increasing their inflation pressures, they would have been underinflated, overloaded and a catastrophic failure waiting to happen.
If your tires' tread depth will be within 4/32” of each other, you can get away with replacing just one or two tires. If you drive an AWD vehicle, the tires must be within 2/32” of each other. But you should always check the vehicle owner's manual to see what the manufacturer recommends.
If you're asking, “can I drive a flat tire 2 miles?” . 5 more than the recommended distance. Technically you can, but you'll have to be ready for additional vehicle damage. Furthermore, the most significant scare would be traffic accidents.
But if you MUST use it, it's always a good idea to use the donut only on the REAR of your car. There's a couple reasons for that: Most cars weigh more in the front, so you'll be putting less stress on it by using it in the back. Your braking force comes mostly from the front.

Whenever you check the spare tire, look for cracking in the sidewalls and in between the tread blocks. If there are light cracks that the edge of a penny don't catch on, you are alright to use the spare tire and just have it replaced after usage.
No you will not save any fuel from removing the spare its weight is not enough to improve your mpg.
Does removing a spare tire make a car faster? It would marginally decrease rolling friction by reducing total vehicle weight, but top speed is dominated by aerodynamic drag which wouldn't be effected. So top speed might go from 100.00 mph to 100.02 mph - an unmeasurable difference.
How long do spacesaver Tyres last?
The maximum distance you are advised to travel on a saver tyre is normally around 50 miles (as the wheels have a limited 3mm tread) but if it's necessary you can drive up to 300 miles.
Can Your Spare Tire Be Smaller? As discussed above, your spare tire can be smaller, and in fact, most car manufacturers now install smaller spare tires rather than full-sized spare tires. These tires are also known as Donuts or Safe-saver. They are meant to get you to safety in case of an emergency.
Space saver wheels are additional tyres that are stored in the vehicle, which are smaller and thinner than your vehicle's regular tyres. They are designed ONLY to get you to a safe place in order to get a regular tyre fitted.
The main reason your spare tire is smaller is that they are meant to take up less space in your vehicle. The spares usually have a smaller diameter, narrower width, and shallower tread, which means they make great space-savers.
The wheel itself should have a label or moulding that carries its speed restriction. Is there a maximum distance for space saver wheels: There is no official restriction on how far a driver can travel on a space saver wheel, but around 50 miles is considered to be the maximum safe distance.
The main difference between spare tires and donuts is the size of each of the tires. So which one is best for you? It's more common to find donuts in sedans or smaller vehicles. Larger vehicles such as trucks or SUVs are more likely to come equipped with a full-size spare.
Full size spares can be matching or non-matching. A matching full size spare is identical to your other tires and should be incorporated into your regular tire rotation. A non-matching full size spare has lighter-weight construction and shallower tread depth to reduce weight and make it easier to install.
Not all donut tires are suitable for all vehicles. It means that you cannot use one spare one for many different vehicle models and vice versa. The reason is that each type of spare part has a unique design with parameters specific to a particular vehicle.
Usually, the maximum speed you can drive on a space saver wheel is 50mph, and although there is no official restriction on the distance you can travel using one, around 50 miles is generally deemed to be the maximum safe distance for usage.

How many times can you use a space saver tyre?
It is not recommended to refit a space saver wheel is used for more than 50 miles as the grip is already weakened in comparison to the normal tyres. However, the car mechanic that fixes your flat tyre or fits a new tyre, will be able to recommend whether you need to buy a new space saver.
A spare tire (or stepney) is an additional tire (or tyre - see spelling differences) carried in a motor vehicle as a replacement for one that goes flat, has a blowout, or has another emergency.
The main reason your spare tire is smaller is that they are meant to take up less space in your vehicle. The spares usually have a smaller diameter, narrower width, and shallower tread, which means they make great space-savers.
Over the past decade, more and more car manufacturers have ditched conventional spare wheels for tyre repair kits. They cite two main reasons for this: repair kits take up less space and are lighter, thus aiding fuel economy. But there's a third reason: cost.
For a start you have to be sure that the spacesaver has the same number of lugs (pins to attach the wheel to the hub) as your car. These also have to be the same pattern as your car and the same distance apart. If they're not, the space saver won't fit. Simple as that.
If your flat tyre is on the front, and your car is front-wheel drive, swap one of the rear wheels to the front and put the space saver on the rear - this is because the front of the car is used for steering, braking and acceleration and therefore it needs the best rubber at the front.
The short answer is yes. If you think about it, space saver spare wheels frequently have a smaller diameter than regular wheels. For emergencies, using a smaller wheel to get you home or to a tyre repairer is fine.
