3.5 mm tyre tread

  • 03-07-2018 2:48pm

    So my car dealer checked tyres in March and rear tyres were at 3.5 mm tread and said to get it changed in July.
    I am not good at measuring treads and wondering if they are like less than 2mm now after driving 1600 km since last service? I know it's a tough question as tread wear depends on braking, acceleration, etc. But how long would it take for tyres to go down by 1.5 mm?

    Check your tread wear block as it depends on type of driving/compound of tyre/mechanical state, if flush with the tread it needs replaced

    You can get a tread depth gauge pretty cheap in Halfords or probably any motor factors. Other than that, the gold part of a Euro coin is 3mm.

    Also don't go to the dealer for tyres. It'll be cheaper to go to an independent tyre shop.

    "Shop around for tyres", i think thats what you meant to say :).

    If your tyres are 2mm now then you still have a small amount of life left in the tyres. To maximize what thread is left you could rotate the tyres on the car to ensure they wear evenly. I tend to put my near spent tyres on the back axle and they last much longer there than if I left them run out on the front. Then the new tyres eventually go on the back and I swap over again when the fronts are getting worn.
    Definitely shop around for tyres. There is bargains to be had if you put in the effort in searching.

    Which is something that loads of people do, while you should never do...

    Wow, we went from tyre depth to whether to put new tyres on front vs rear in 7 posts :D
    New record y'all!


  • Closed Accounts Posts: 3,292 ✭✭✭TheBoyConor


    But sure in that video they are probably deliberately trying to get the darker car to spin. Sure look at the speed of it and the way you can see the steering flicking to get it to fishtail.

    Particularly if you are like the OP and have a RWD car. I wouldn't be putting 2mm tyres anywhere other than in the bin.


  • Closed Accounts Posts: 3,292 ✭✭✭TheBoyConor


    The minimum legal requirement is 1.6mm. Bear in mind that anything above that will pass an NCT which is strict and so if you are replacing tyres with 2mm you are wasting your tyres. Also, I would expect the the 1.6mm limit probably has a safety factor included in it.

    And 2mm is even safer due to the tyres having more space to displace water. You'll hydroplane on with 1.6mm before you will with 2mm.
    Each to their own but I'd prefer to do what is safe.
    Real life example - smoking cigarettes is legal but is it safe?

    Sort of but by shopping around you'll usually arrive at my point regardless if you want a decent brand. 60 a corner in an independent will go further than a dealer if you're looking for quality :)

    Should I simply ignore a dangerous advice given?!

    The NCT is not strict. They say themselves it's a snapshot in time, that all it tells you is that the car met a minimum safety requirements on the day in question and nothing more.

    A 1.6mm tyre is scrap, a 2mm tyre is also scrap, it's just legal scrap, you're literally splitting hairs talking about a 0.4mm difference being worth anything. The RSA recommend that a tyre be replaced at anything 3mm and below to maintain good performance.

    The wet braking distances of a 1.6mm tyre will be considerably further if not a multiple of the same tyre with 3mm+ left.

    They were probably 7mm when new, so how long did it take to get from that to 3.5mm ?

    Generally, ii would take 10k kms + to scrub off 1.5mm but as you said there are many variables to thrrow into the mix.


  • Registered Users, Registered Users 2 Posts: 5,915 ✭✭✭masterboy123


    Thank you for coming back to the main query.
    New Mechellin were at 8 mm and did 30k kms so far on them until it reached 3.5 mm. Well according to this I have over 10k kms left.

    I will check the gold part of euro coin today.

    The harder compound tyres last longer. Basically "good" or expensive tyres are soft so they will wear away quickly. Other harder types of tyre like van tyres are harder and they will last much much longer.


  • Registered Users, Registered Users 2 Posts: 3,027 ✭✭✭Lantus


    Just because you can drive on tyres to the bear minimum doesn't mean you will get value if you suddenly need to stop for a car or child. Especially if your driving involves motorway where tyre integrity and grip become more important.

    Sorry, I didn't mean to criticise you :)

    All threads on tyres end up in the rears vs fronts discussion, but usually on page 2 :D


  • Registered Users, Registered Users 2 Posts: 5,915 ✭✭✭masterboy123


    So I took pictures of my tyres and used a special tread measure tool :) see in the pic attached. It appears I am at 2.5 mm level at the moment. Please notice the tyre tread block, is it the one in the middle or outer side?

    A digital one of those would be way easier on the eyes masterboy :)

    I think they can be gotten cheap enough on ebay too :)


  • Registered Users, Registered Users 2 Posts: 12,917 ✭✭✭✭Toyotafanboi


    Any time now would be good to loose those tyres IMO, they are nicely worn. Theyll be grand in the dry so it wouldn't be an immediate concern with this weather but definitely for the Autumn.


  • Registered Users, Registered Users 2 Posts: 2,172 ✭✭✭EPAndlee


    I'd definitely be changing those tyres

    Energy Saver +... They one of the faster wearing Michelins I've seen...

    Change them before Autumn for two all-season (not summer) tyres.


  • Registered Users, Registered Users 2 Posts: 5,915 ✭✭✭masterboy123


    What's energy saver+? It's Michellin primacy 3.

    I am thinking of getting Goodyear Eagle F1 Asymmetric 3, got good reviews on boards and online. What do you reckon?

    My mistake :D The Energy Saver+ I had had virtually identical tread - the differences could be blamed on size difference...

    Very good tyre. But I will keep suggesting all-seasons. We will be getting snow much often than in the past, the all-season will keep you on the road rather than in the driveway.

    Goodyear 4Season Gen2... Or Michelin CrossClimate+... ?


  • Registered Users, Registered Users 2 Posts: 5,915 ✭✭✭masterboy123


    I checked reviews for 4 seasons tyres and good mixed reviews. Fuel consumption appears be more on them and are noisy. My work arranged transport during snow storm period so hopefully I don't need to drive in snow.

    I will get my hands on the Goodyear Asymmetric 3 this time.

    Michellin Primacy 3 lasted 25k kms on fronts and 30k kms on rear, that include mostly motorway driving. Will try Goodyear this time.

    I love these threads and advice.

    I swap front to rear but I don't wait till there bate first.

    That video is rwd dependant. And under specific conditions.

    Reason they recommend it is for the average driver a front wheel slide is easyer to correct than rear.

    But for a front wheel drive car or can I still prefer better to front. It does your steering and braking. It takes most of the weight in a corner.
    It clears most of the water for the rear to follow in.


  • Closed Accounts Posts: 2,655 ✭✭✭i57dwun4yb1pt8


    i change at 3 mil, and they are all at 3 mil by then as i rotate religiously every 8 k or so .

    i find at 3 mil they start to spin on the fronts on take off, in the wet
    thats when i know they are fooked.

    I'll let you know about the Goodyear F1 AS3s. I'm putting all 4 on tomorrow. Moving from a Michellin Sport 3 and 4s. I'll never use the 4s again, but that's just personal. Others do love them.

    Grand stuff.
    People suggesting to change to new tyres and I don't want to go to dealer again. So I am thinking to get Goodyear F1 this week.
    How much did you pay and did you get them online? The difference is only 15-20 euros for 2 tyres if you order online.

    And thank you all for helping me out. My Boardsie decisions are always great :)

    Another quick question.

    Do tyre shop usually charge extra 30 euros if I request them to put new Goodyear in front?? The front ones are 4 months old.

    I'd get them locally so.
    I'd not consider that saving worth the hassle :)
    I've never bought tyres online and don't plan on either, latest yoke is on 19s.


  • Registered Users, Registered Users 2 Posts: 5,915 ✭✭✭masterboy123


    Thanks.

    Is it a wise idea to replace new tyres on the front? Someone posted video that for rear wheel drive it's better to have new ones on front. While other sources it is fine to have new tyres on the rear.

    You could have plenty of grip in the rear as you aquaplane into something. Cos your fronts can't clear water effectively.

    Replace the old tyres and rotate if needed to keep better at the back.

    A year will not make a significant difference though - so if your front needs replacing just after a year you have new tyres at the back, just change the fronts.

    Sorry, I think I was unclear in my earlier post.

    I got 2 new front tyres 4 months ago only. The rear 2 tyres needs replacement now. Do you suggest I get the brand new tyres on the fronts and rotate 4 months old on the rear, for better grip in the wet conditions?

    Your front tyres are effectively new anyway if you've only put 1600kms on them.

    If your sticking with the blend of Kumhos and Michelins, personally I'd leave the Kumhos on the front seeing as they are already there and pretty much brand new in an effort not to over think things.


  • Registered Users, Registered Users 2 Posts: 5,915 ✭✭✭masterboy123


    Thank you! That's clear.

    I am getting Goodyear F1 Eagle for rear side. Not getting another Kumhos as they take away the beauty from the car (friends made remark). Once Kumhos wear down I will get Goodyear for fronts also.

    So these are my Goodyear Asymmetric F1 Eagle XL.
    You can see quite deep tread.
    I am happy with it's breaking and grip.

    It appeared that I have been over inflating my tyres. Recommended on these are 33 psi on cold tyres. I always kept them at 36 psi, as recommended in my car manual, but tyre man suggested it's too high pressure.

    Great tyre, quiet and efficient, but very soft and quite prone to annoying punctures. Make sure you have access to some place local for the inevitable fixes.


  • Registered Users, Registered Users 2 Posts: 5,915 ✭✭✭masterboy123


    That's bad to hear, that it's prone to punctures :(

    This brings me to ask another question. My car doesn't have an extra tyre in case of a puncture and rather comes with a small electric device to inflate tyres, can this device be used to inflate non-runflat tyres?

    It depends on the weight of the car and other factors. Unless that 33 psi is recommended by Goodyear specifically for your car, I'd stick to the 36. The maximum pressure will be much higher (should be printed on the tyre somewhere) so it's not dangerous.

    Yup............but whatever caused the air to escape needs to be plugged first (by gunk type stuff or by actual strip plugs)

    I do several 150 mile long journeys a month, a full size spare is essential IMO.
