Safe-Saver/ Donut Spare Tire Your owner’s manual will give the recommendations for driving time and speed. A general rule of thumb is to drive no more than 70 miles and no faster than 50 miles per hour before replacing your donut with a new tire.
It should say right on the side of the spare tire, or on the wheel itself on a large, prominent sticker. If that’s missing or illegible, the rule of thumb is to not drive faster than 50 mph with a donut spare tire. Going faster could cause tire failure, differential damage, or both.
When you are driving on the temporary spare tire, you need to keep your speed down. It’s not a full tire, and it is not meant to be driven as one. You will want to keep your speed to 50 MPH or below. Since you can ‘t go above 50, this means that you cannot drive on the highway with it.
Here are a few things to note when driving with a donut tire: This is because they are more compact, so the guideline is the spare tire should not be driven faster than 50 mph. While you can drive on highways with donut tires, it is safer to stay off of them as you will only be able to go about 50 mph or less.
Donut tires are only meant to be temporary fixes for a flat tire until you can safety reach a Chicago area service center to get your tire replaced. In general, most donuts should not be driven on for longer than 50-70 miles.
Spare tire prices vary greatly depending on the type of spare you purchase, and often start at $100 and go up. A full-size matching spare generally costs more than twice that of a compact temporary. Some donut tires can be purchased online for as low as $50, but are more expensive at a tire retailer.
I’d say a solid 100 miles at least. Typically, most manufacturers state that the “ donut ” temporary spare is good for approximately 50 miles at speeds up to somewhere around 55mph. I do know people that have driven farther and faster than these limits, but the tires are not designed for this type of use.
Some time ago a rep from a tire manufacturer says a compact spare will last up to 3000 miles before it wears out. Of course no one is supposed to put that much mileage on them since they are intended for temporary use. But they are intended to be used repeatedly so long as they are not worn out or damaged.
A donut is designed to get the job done, but there are some important differences. First, the tire pressure is much higher, typically as high as 60 PSI. Certainly, it can get you back on the road again, but you’ll need to have the spare replaced as soon as you can, as donut tires are designed for a quick fix only.
they expect you to replace the stepney as soon as you fix the regular wheel. Nowadays it is a trend by manufactuers to supply a spare wheel of smaller size. They mainly do it to reduce cost [and thus make for profit]. However, it is recommened that you replace this with a standard wheel.
Often, the blowout will occur simply because the driver didn’t properly inflate their truck’s tires or they failed to change a tire that’s overworn. In both of these scenarios, a blowout can stem from tread separation, which causes the tire to rapidly lose air pressure and explode.
The air pressure or PSI of a donut spare tire is 60 PSI. If you have a full-size spare, the air pressure should be the recommended pressure on the side of the tire; typically between 32 and 38 PSI.
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.
The Dangers of Doing Donuts Doing donuts doesn’t simply damage your car. If you really can’t resist the urge to burn some rubber, avoid doing donuts in an empty parking lot and go to a drifting track, instead. You’ll be less likely to damage your car or injure people.
You may not think a tire expires, but tires are not meant for use beyond 10 years from the date they were manufactured. While a tire’s life may last longer than 10 years, it’s rare. If the manufacture date on the sidewall of the tire makes it older than 10 years, have your spare tire replaced. Check the tread depth.
