Buy a pair of new tyres or just 1 tyre? (11,500km old)

One of my front tyre got a nail puncture on it and is unrepairable according to Costco (not close enough towards the middle). They happily took it out and replaced it with my full size factory spare free of charge. My car is bought brand new and have only done 11.5k on it. Its Kumho branded. The problem is: the full size SPARE DOES NOT have TPMS (tyre pressure monitoring system) on them so future pressure of the tyre wont be detected on my dash:

Costco suggest I should buy just 1 new same model Kumho tyre with TPMS (from beaureapaires or Bobjane) and put it in the front, and then return the spare that is currently on (without TPMS) back to the boot.

But then having read around,the new tyre would have different thread level etc to the exiting 3 tyres on. Does 11.5k old tyres matters?

Or would it be better to buy a pair of new Kumho tyres (with TPMS) and put them both in the front, which means that I'm kind of throwing away the other relatively new tyre away.. (it would be a easy decision if the existing tyres were old lol)

    Buy a new pair and you can resell the tyres you don't use as second hand if they are still good

    Edit: Just read your post properly. Surely the TPMS is on the rim not the tyre, so of course the spare doesn’t have TPMS? So get the spare tyre swapped to the other rim and you’re done.

    I’d be surprised to learn TPMS is on the tyre itself??

      Yes, I've already put the full size spare from the boot to replaced the punctured tyre. However for some reason, the full size spare does not have TPMS so I won't get any Tyre pressure reading on my dash from that tyre in the future. Costco suggest I buy a new TPMS tyre and return the spare (without TPMS) back to the boot.

        TPMS is fairly non essential IMO.

        I would just leave as is for now then. Get 4 new when you’ve worn them out.

        The tyre doesn't have TPMS, it's fitted to the rim. Just means you spare wheel doesn't have it fitted which is normal. You just need a regular tyre and should be able to get away with just replacing one given the km.

        Get a second opinion on the repair though. Generally if it's in the tread it can be fixed, sidewall can't.

      I actually have no idea to be honest, that's what they told me. My last car was a 2001 corolla. Im new to this TPMS thing myself.

      • Skramit on 03/09/2019 - 18:03

        Weird. All the cars I’ve owned with tyre pressure monitoring is based on RPM of the wheel. When one tyre spins at a slightly different speed the car computer detects one is flatter than the other.

        If your car has some other fancy thing for TPMS then I’m stuffed and have no idea. I’m just staggered u can buy tyres with it build in. Seems unusual and very niche.

        What sort of car is it?

        • username999 on 03/09/2019 - 18:14

          Its nothing special. Hyundai i30 hatch 2018. They initially said,"we'll just replaced the punctured tyre with the full size spare you have, then you can buy another new tyre to put it in the boot when you have time".

          After replacing tyre, they then told me that the spare doesn't have TPMS, and I can get a new tyre with TPMS and put the current spare one back in the boot.

            @username999: Fair enough. As I said about I wouldn’t worry about TPMS in general. If you ever hit another nail and get a flat, you’ll know about it with or without it.

            And you should be checking tyres every second petrol fill up anyway.

    11.5k isn't that much unless you're a hoon driver. A good set of Kumho's should easily last up to 60k

    I'd follow Cosco's suggestion.

    Just buy 1 with TPMS and put it on the front and put the spare in the boot.

    • username999 on 03/09/2019 - 18:19

      Yeah Im leaning towards that option. It just that a bit of googling about how it's better to replace a pair of tyres rather than 1, (because of thread level etc) made me kind of worried. But I'm in no way a hoon driver lol.

      • donga100 on 03/09/2019 - 21:42

        Keep the spare on and buy a new tyre to pair with it. Keep the tyre with 11k on it as your spare in the boot. This way you get balanced tyres and only need to purchase one.

        • username999 on 03/09/2019 - 21:58

          Yeah that would be the ideal option with balanced new tyres. But the current new spare does not TPMS as stated in the post, hence the issue. I would ideally want the four set of wheels to have TPMS (If that even matters). The 11k old tyre have TPMS.

    I love you, too, Pepsii Pepi.

  • garetz on 03/09/2019 - 19:27

    Why would you throw it away ? Just keep it as a spare.

  • k-rokfm on 03/09/2019 - 21:04

    Go through your dashboard and try to reset the settings - when we got a flat it didn’t automatically reset I had to do it through the dashboard

    Can't u strip the tyre from the spare to your rim with the tpms and buy another tyre as a spare any brand as it's a full size?
    Ideally replace tyres on the same axle at the same time but 11.5k is pretty low chuck it on the back and let it wear a little.
    You have a direct tpms so a physical unit in the tyre at the valve so most likely a metal valve tube the other type is an indirect so ECU monitored usually via abs sensors. You cannot buy a tpms tyre.

    OP There's lots of info online about the Hyundai TPMS.

    Pretty sure its not on the rubber itself and you may need to drive a certain distance to get it to register again.
