Should I Replace Both Tyres or Just One?

Hi guys, unfortunately had a sidewall damage to the front left tyre.

My car is an auto 2019 Suzuki Vitari, I think just front wheel drive. Car has had roughly 50,000 km. Do you think I should replace both front tyres as it is better for the axle?

Also my tyre size is 215/55R17. 94V

I've seen similar tyres except 94W for $140. Does it matter if I mix 94W and 94V…is it just the speed rating?

Thanks!

    If all your tyres have done 50000kms, it's about time to replace all of them.

      I just replaced all 4 on my car last Thursday with 90000kms. If you run the correct pressure, rotate on a regular basis, have a correct alignment and don't drive like a bogan drifter in a VT Commodore then you can get better mileage (unless of course you run high performance soft compound tyres).

        Age of the tyre is important too, if they're old with minimal usage, they can still be bad (dried out rubber)

        • -1

          If you park undercover it will be a decade before they dry out.

      • This is a great comment

      • What tyres?

      • +1

        Thats a long stretch for tyres Muzeeb

        What where they made of?

        50-60K is normal for tyre replacement.

        But of course without seeing what tread is left on the tyres one cannot come to any conclusions

          Black rubbery type substance.

          • @MS Paint: So what tyres were they??

            • @CVonC: Bridgestone Turanza Serenity Plus

              • @MS Paint: Nice, they already have the 50k guarantee too.

              • @MS Paint: The most KMs I saw on these tyres was 120,000. It was done by an uber driver on an Audi A3. He still had life left on them when we replaced them.

              • @MS Paint: SERENITY NOW

          If you live somewhere where there aren't many turns you can get incredible tyre life.

          • +2

            @sumyungguy: And don't dry turn every time you park the car. Just because power steering makes life easier doesn't mean you aren't slowly destroying your tyres.

      • If you only did city driving with a lot cornering it would be very hard to get 50000km. Only combined with highway or a lot of highway you can achieve that good tread

      • @Muzeeb

        1) What was the thread depth remain in your tire whence you replaced at 90K?
        2) How old were you're tires
        3) Anything below 3mm of thread depth significantly increases stopping distance so max you can push upto 2mm if you want to chance it.

        I ask because I had a 6 year old tire with 50K and 3-4 mm tread depth but there were minor cracks appearing in the tire with age so I replaced when there was a Michelin promotion $150 + $200 Executive discount at Costco

        • 1) Just approaching the tread depth indicators. The tyres had even wear all round. I rotate them every 10k kms
          2) Right on 2 years - yes I do a lot of driving. 80-90% is regional roads and 100km/h.
          3) I understand the importance of tyre condition and remain on top of it for my own safety.

          • @MS Paint: Great. My driving is mostly stop start local driving as I take public transport to work plus the age of my tire is 3X of yours

    • +1

      Depends on how you drive, regional or city kilometres, rotate tyres regularly, wheel alignments and balances.

  • What's the situation with your spare? OK, I looked it up… space saver.

  • Rule of thumb is changing all four is best. But of course the cost is 4x.

    Pairs are better than singles. but of course, single replacements can also be done - they happen all the time, and I have done them a fair few times over the years. It was usually budgetary constraints that made me take that route.

    IMHO, it won't really be too much of an issue with your axles. It will however be an issue when you invariably need to rotate your tyres later on. Sometimes if the wear levels aren't too far off, you wont' have any dramas at all. A tyre specialist you trust can guide you through it.

    In my case, during those times that I just replaced ONE tyre, the tyre specialist arranged it in the best possible way so that I would continue to have the best compromise between performance and longevity in the life of all four tyres.

    AFAIK, 94v /94w are speed ratings. it should be ok to mix. However, I'm very very surprised that the 94w is coming out cheaper??? I honestly thought they'd be way pricier.

    • Do you know much about all wheel drive systems… I’ve heard changing all 4 at a time is required for AWD e.g., Subarus etc. assuming this is correct, does this also apply to hybrids which claim to be AWD whereby the front axles are driven by the engine and rear axles are powered by the electric motor (I think that’s how they work).

  • If you do drifting in your Vitari you should get eco tyres for the rear and performance tyres for the front.

    Yes

    I also damaged the sidewall of my front tyre. Should I replace both of them or just one?

      Was waiting for jv to post this.

    I don't get the "all four", never done that, never will.

    But having the same tyre with similar wear on both sides of the axle makes sense. Similar grip, less risk of things going wrong. Unless you have extremely hard wearing tyres with very little wear and can get exactly the same model to match, you better get the pair replaced.

    • "I don't get the "all four", never done that, never will."
      problem with that is you need to make twice as many trips to tyre shop
      .

  • Since its a front tyre you’ve damaged on a front wheel drive car, I'd recommended replacing both front tyres. A large difference in wheel circumfrance will casue additional wear to the transmission, and potentially damage.
    If it was a rear tyre, you could get away with replacing just one.

    • +6

      why not just replace one, and rotate rear to front?

    What did the tyre place recommend 2 or 4 based on K's potential left for the additional 2 tyres?

    You should have roughly equally worn tyres on you drive wheels.

    If the tyres have 50k on them theyll be at least half worn out, plus theyre getting on in years amd pro aly due for age based replacement anyway.

    • Yeh, yeh, nah. 50,000km is only 5 years even at half the averge annual mileage. Decent modern tyre should last >10 years. OP should be able to tell if there's any rubber degradation.

      Reputable tyre places will give him the best advice but fwiw:
      -OP could look at buying a second hand tyre (or possibly 4) from a dealer then wait for 4/3 deals and do the lot.
      -Alternatively buy 2 new for the REAR wheels. https://www.jaxtyres.com.au/knowledge/tyres/when-fitting-jus…
      -If he chooses to buy one new tyre (not advisable) then it should be put it on the non-driven axle afaik.

      The V/W speed rating difference mentioned is negligible and can be ignored (as long as it meets vehicle specs).

  • Change both front tyres, then wait for the half-price deal to change the two at the rear.

      There are no stupid questions, although this forum does get its fair share of what could be considered fairly common sense questions.

      If you don't know, asking here could save you from getting ripped off by a tyre shop. Eg "my tyre is 2 weeks old and has a nail in the middle of the tread. Tyre shop wants me to replace 2"

      • -8

        Well, sorry that one is.If one has to ask if you should replace one tyre, well yes it is stupid.Go to a tyre outlet not an Oz bargain forum for an answer. Common sense should prevail, unfortunately some people don’t possess that.

        • +2

          Go for advice to quite possibly the only place that has a vested interest in overselling you the product you're enquiring about? Doesn't sound very ozbargain of you.

      • There are no stupid questions, although this forum does get its fair share of what could be considered fairly common sense questions.

        Of course there are stupid questions- asking how to fit a 77" TV into a room the size of a large wardrobe being a good example. It's stupid because it both defies common sense, and because can be self-answered simply by putting four post-it notes on a wall and staring at it, or walking into JB Hifi.

        • The question may appear to be stupid or common sense, but without knowing the context of the person asking we dont know if theyve got some issue. We dont know if they have any of their own life experience. We dont know if theyve come from another culture and dont understand ours. Maybe they have learning difficulties.

          By all means call out your mates for a stupìd question, but discourage others from trying to learn.

          • @Euphemistic: The context was pretty clear in that instance- old enough and experienced enough to own or rent a home and knows what a television looks like. I'm pretty that sure outside of uncontacted tribes in Papua New Guinea and infants televisions that tape measures and televisions transcend culture and life experience.

            https://www.ozbargain.com.au/node/836901

            That thread wasn't trying to learn, that thread was all about "too lazy to activate brain."

            And it was followed up with this gem of "will 80cm of fridge fit into a 60cm space": https://www.ozbargain.com.au/node/838576

            Asserting that there is no such thing as a stupid question in the face of things like this is just OTT political correctness.

            • @rumblytangara: Ok. Looking ar those thrwads, neither is a stupid question either. Aski g for experience with a huge TV on a wall it would clearly fit on, but asking about the distance to the couch. I normally sit in front of a 75" not much further from the screen. Its fine.

              As for the second, it wasnt looking for if an 80cm wide fridge would fit in a 60cm wide space, but more if 180mm sitting out in front of the cupboards was too much. Again, quite a normal situation. Fridge sticks out further than the cupboards in many places.

              Plenty of reasonable responses in that thread. Ergo, valid question.

  • you can replace the one legally providing same size and suited to the vehicle however particularly if its the front and you dont want drivability issues in regards to steering/wheel alignment/ABS (braking) etc is to replace both tyres.

  • -1

    look on facebok marketplace for a tyre places that sell 2nd hand tyres. and get a single tyre from there.
    give them the tyre dimensions and get a quote.

    one time I had a rental car in melbourne and the front left tyre sustained damage . tyre place swapped over a similar tyre for $50.

    • Nothing wrong with that option despite the negs.

  • Maybe private health insurance is another option to mitigate risk to injury!

  • What’s your spare like?
    If it’s old or worn you can replace the 2 front and put the other one as an updated spare.
    Either way with 50k and possibly a few years on them I would replace both.
    Tyres are important for you and yours to come home safely each evening…..

  • If it was 4wd would matter. So only if you got the "upgrade" from what I can see. Going to have less grip on the old tyre when doing sharp turns. Didn't like it myself and would get a pair vs single.

  • Personally, I'd do both.

  • -1

    It depends.

    Go to a tyre shop and ask them to check and show you how much life is left on your remaining tyres. If its less than 10k km or only 1-2 years. Then its better to replace all 4 as the shops will usually give you a discount package and works out to be cheaper per tyre.

    If remaining life is >3 years, the i would just replace the one.

      While your at it, call in your barbers and ask if they think you need a trim.

  • Both. End.

  • I would replace both fronts. Mixed fronts might affect your braking stability in an emergency situation.
