    I'd hate to own this car on NZ. Don't they inspect their cars every 6 months?

    Ya, nothing new there. But Mazda thinks its "sporty" for a car to behave like that.

    Once the tyre surface begins to wear unevenly, the thinner part will not be able to cope with the same amount of stress as the rest -> Tyre Failure.

    Getting tyres swapped on the rims or Camber Arms will help. Ideally though, if you're going to start playing with the camber, you want to adjust the Toe too.

    Most people would be lucky to get 30,000ks on a set of decent wearing tyres (OEM not included).

    So what does it cost to remove tyres and rotate between rims? $100.

    You do that every 5000ks.

    Then let's say that extends the life of the tyre from 30k to 40k.

    Means you done this 7 times, @$100= $700 to get extra 10000ks.

    Over 120000 k's, you would spend $2300 on the above technique ($100 x 23 times) but only changed your tyres 3 times. Plus the cost of tyres ( assume $350 a corner) $4200 = $6500.

    If you just rotate, means you're buying new tyres every 30000k's, that 4 times over 120000k's = $5600.

    Unless you're riding on some super expensive compound, plus youre getting greater wear, it hardly seems worth it.

    Or, if you could get them moved for less than $80 a go, you'd about break even.

    Of course, I very well could be underestimating the effectiveness of this technique and overestimating the cost of moving rubber between wheels.

    I'm going for 5 tyre rotation every 5000k's on Michelin PS3's. Will see how that goes.

    I have been doing a wheel alignment every 10thousand k's I got about 30,000 out of my stock tyres. The tread is still good but the insides have the canvas showing now sitting on 34,000 and getting them replaced this week. Cost of alignment was $50 each time.

    Are you getting OEM tyres? They quite expensive. Check the tyre thread for some alternatives.

    2. Maxxis
    3. Goodyear

    S/S
    1. Dunlop
    2. B'stone
    3. Toyo

    Overall road tyre winner Bridgestone Potenza Adrenalin RE001, closely followed by the Maxxis Victra i-pro (which are also $324 cheaper for a set!). Overall semislick winner was Dunlop by some margin.

    Pretty good value out of the Bridgys as well, if you remove the dead last by some way Federals the Bridgys are third cheapest at $296/tyre... and you should be able to find em cheaper than that as well.

    No. My neighbour owns a garage and is doing me a deal on something. Will let you know what type on sat at breakfast.

    About to get new tyres, so thought I would move fronts to the back in the mean time.

    Here are some pics of the inside tread wear. This is the driver's side front. The Passenger side is bad, but not as bad as this.

    Just got them today. Speaking to the manager at Goodyear Dural. He said my toe out was extreme. The combination of camber + extreme toe caused my inside edge tyre wear.

    He wants me to drive it for a week and then come back to re-adjust the toe. He thinks the Mazda specs for the toe on the Gen 2 is incorrect. I'll get a printout on the settings on my next visit.

    He was speaking to a Mazda dealer today in Sydney (that I won't mention) that has seen this problem too often (off the record). This dealer has adjusted the toe out settings against the recommendation to try and fix the issue.

    On my next visit he's going to make the same adjustments to my car. Will be interesting to see what the standard vs new settings are.

    Anyone know what Mazda recommended the toe/camber settings are suppose to be for a stock Gen 2 ?

    for a stock height mazda 3, the bush should be fine to bring the rear camber closer to -1.0.
    but for a lowered mazda 3, the arm would be better suited, as you need about 3 degrees adjustment to bring it back to -1.0.

    personally i think it is money well spent. $120 to extend the life of you tyres 10,000km per set.

    specs (toe/camber) i see for mazda 3 amaze me for a street car. especially the specs mazda allow/describe for a mazda 3 mps. it is someone from a race car. worth some tweeks to the settings, you'd easilt get 5-10,000km extra from a set of tyres, even before you supply aftermarket parts to make further adjustments.
    been saying the same thing for a while. i posted that back in September last year.

    personally i would not be running negetive toe if it is a daily driven car. no matter what the manufacturers says i should.

    if you will want an aggressive alignment setting, then +0.5mm per side on the front and neutral on the rears should still give a good turn in when the rolling forces move the angles of the wheels. and will increase the life of the tyres by mountains.

    Thanks for that projectrracing.

    This is my daily and I've only been to the track once and given the expense of these tyres I'd rather them last a bit more than 20,000kms.

    Wheel alignment done today.

    Here are settings from the printout they gave me -

    Front Axle (previous/current)

    • Toe Left == - 0.7mm / + 0.6mm
    • Toe Right == - 1.1mm / + 0.6mm


    Rear Axle (previous/current)
    • Toe Left == + 0.2mm / + 0.2mm
    • Toe Right == + 0.2mm / + 0.2mm

    that is more sedate settings than what even i suggested. how does it feel?

    So far so good.. I haven't driven spiritedly as yet but will see how it goes on the weekend.

    This time around with new tyres I think I will pay much more attention to tyre wear and rotation every 5000kms. I think I was to relaxed with the OEM set, thinking my dealer would know best.
