How safe of those skinny temp tyres

I had a flat this morning and put on one of those skinny space saver tyres that come with the car. I drove home, and it seemed ok. I was thinking of getting it changed on Thursday - is that a bad idea? Should i get it done asap? Is there a major safety issue there?

(sorry, thursday, not friday)
 
just keep under the speed limit on the side of the tire and it should be fine. also, if you have an FWD car the donut goes on the rear. dunno about RWD cars/trucks.
 
Stay off the highways/freeways and you will be fin until thursday. I have used one for months in the past

On RWD cars, the donut goes on the front.
 
You're safe. I did >600 miles of driving on a donut in the summer. I know I shouldn't have but I was really left with no other option. at least 10% of it was freeway driving (65-80mph).
 
I regularly did 70+ mph on a 20 year old never-been-used donut over the summer (after topping up the air, of course) with zero issues except it made the car look stupid and I couldn't corner very hard with it on there. The donut spare is grossly underrated at 50MPH max speed - that rating is there for other reasons (specifically, when it is placed on the drive wheels by a clueless owner). You will be fine.

And yes, the donut goes on the NON-drive wheels. If the car is awd, drive (slowly) only when absolutely necessary and change it ASAP.
 
Just make sure they are inflated to the proper pressure (which I think is around 60 psi). It's a good idea to check the pressure on these spares before you have to use them as they do lose air with time.

You stupid or something? Those things are only supposed to be used for emergencies to get you to a place that can repair/replace your damaged tire.

Yes..I am a complete moron. It was the stupidest thing I have ever done in my entire life. I should have reached into my pocket and pulled out all sorts of imaginary money to get it fixed right away. You think after driving on them for a couple days they self destruct and your car blows up?....Jesus, get a clue.

 
Wow, I'm amazed anyone actually admits to being stupid enough to stay on one for a long period of time, even taking an onramp feels unstable, you can actually feel the opposite wheel not making contact with the road, and the donut slipping. Skip a couple lunches and get to a junkyard, used tires can usually be had for $20-50, and while still a bad idea at least you are not completely unsafe.
 
lol, I've done 100+ on those things on the NJ Turnpike. I never have them on for longer than a few hours though...too embarassing.
 
The correct spelling is
doughnut. If you haven't already replaced it, just stay below the speed limit as posted on the sidewall, and make sure it's inflated to the proper PSI! I think my donut tire needs 55 PSI, and my cheapo tire gauge maxes out at 50! 😀

lol...you say you can't believe how stupid people are to admit to using one for a long period of time. Maybe you should take a look in the mirror, temps are not for highway use, yet you are stupid enough to admit to taking on-ramps.

Temps are plenty safe if not used above the rated speed.

Temps are rated for 50 miles at 50 mph, driving on I75 thru detroit at 55 mph ONCE is way safer than trying to drive thru downtown detroit, but thanks for coming out. And GL trying to convince anyone that you're not the idiot here.
 
:laugh: When was the last time any of you guys have heard of a temp failing because someone was speeding on it?

The manufacturers put that rating on there because it's easier to say "Do not use over 50mph" than "Do not use over 50mph if spare is on one of the drive wheels and also don't take corners fast or brake hard". Everyone who is even a little bit car savvy would know this, but many people don't even know which ones the drive wheels are. And, even for people who do know their way around a car - someone who gets a flat in the rain at night for example, is usually not going to take the time to transfer a good wheel from the non-drive axle to the drive wheels, and put the spare on the non-drive axle.

Using wheels with different overall diameters will burn up differentials / wreck transmissions over a period of time, and do so much more quickly at high speeds - hence the "rating". Not to mention, the handling and braking of the car are negatively impacted with a temp spare on there - which again, becomes a much bigger problem at higher speeds. The manufacturers put that ultra conservative rating on their to cover their ass in the event of an accident being blamed on a temp spare, and also to save them millions of dollars worth of warranty transmission / diff repairs caused by mismatched wheels.

As long as you are mindful that you are on a temp spare and drive accordingly, you could probably double the 50mph speed rating of that tire without any issues.

I'm more concerned about the altered handling of the vehicle, rather than a failing donut.

I did this once, because my dad wasn't going to let me drive with the donut in the front. Completely pouring, lol.

 
Thank God my Expedition doesn't use a donut but a full size spare 🙂. I can drive 80mph loaded with 7,000 pounds and still not give a damn 🙂.

You know what I hate? When a Jeep Wrangler has a lift and big tires, but the spare is a standard sized one, especially because everyone can see they were too cheap to buy a 5th tire
