Need Help Regarding a Flat Tyre/Spare Tyre

Hi guys I was hoping for some simple advice with an issue I am having.

My rear passenger side tyre went flat. I have a machine that puts air and I put it to about 35 but it went down again. The problem is I live 25 minutes away so I don't think it will last long enough. Similar thing happened to my dad's car and removing the flat tyre was really really tough. Maybe because it has not been removed in 14 years?

Anyway, it took me a while to figure out how to retrieve my spare tyre that was under my boot, but after getting it I found something confusing. It says R16. My four tyres are all R19. As far as I know all AWD Captiva's have R19 as the default tyre size.

So what I was hoping to figure out is whether I can use the R16 one and have three other R19s on the car. Temporarily until I can sort out what to do.

Thanks in advance.

My vehicle is a 2009 AWD V6 Captiva if that helps.

    The spare is for temporary use only so if it’s the one that came with the car (when new), then it will be fine

      Space saver spare usually limited to 80km/hr only.

    • then it will be fine

      Sure, if you want to stuff up your differential…

        It's a Captiva, couldn't possibly get any worse.

          Craptiva*

  • Read the instructions on the sidewall of your space saver

  • does the spare has a yellow rim ?

      It’s as mechanically useless as a C43AMG except you’ve spent far less

        It's a coin flip as to which dealer support network is less helpful at this point in history.

          My money is on Holden somehow being the better of the two

        Yeah, but can O.P. get a brake rotors for $2 each?

    Did you find the puncture? Might be able to plug it with a plug kit, SCA and Bunnings sell them

      Anyway, it took me a while to figure out how to retrieve my spare tyre that was under my boot,

      I think being able to plug a tyre is out of the question with the above from the OP.

      • lol true

        Pretty sad really

          No need to down vote him. He is totally right. My dad has always been telling me to learn how to change my own oil and stuff.

    It’s not the R number that matters here for the tyre to fit, it’s the whole package.

    It’s likely the tyre on the space saver is a completely different profile to your regular wheels and that is usually normal. Most space savers have quite a thin tread width to fit snuggly in the boot and compensate diameter with a larger side wall (which also helps comfort given the decreased tread width, but as long as it’s a similar diameter, it will be fine for its intended purpose.

    As an example a tyre that is 225/55R19 on the is the same diameter and rolling circumference as a tyre that has a 175/90R16 profile on a 16 inch rim.

    Further more to this, if you want to be extra safe, you are better off keeping the space saver on the rear. Even with your AWD car, power will primarily be sent to the front until the front starts to slip. Only then will it power the rear. This will also somewhat keep the turning feel fairly consistent too.

    • Thanks so much for the detailed reply.

  • I have a machine that puts air and I put it to about 35 but it went down again.

    How long did it take to go down? Pumping it up to 50 will buy more time. Stop at a few servos on the way to top it up.

  • It is common for modern cars to have a spare that is different to the rest of the wheels.

    If its the spare that came with the car, put it on. If its a smaller tyre/wheel it'll have a big yellow sticker on it that give a max speed.

    If you are really unsure, roll out the spare next to an inflated wheel and see if the diameter is similar. If it is within a cm or 3 of the same height its good to go - but stay under 80 and get the other tyre sorted before you go more than 100km or so.

    Even better, put the spare on the back. A caltiva doesn't drive the rear wheels on hard pavement so it'll be easier on the drivetrain
