Tyres and Renewing Rego

Blue Cat on 10/06/2017 - 19:38

Hello,

I will need to renew my rego in a month and a friend got me worried on my car's tyres.

He said it won't be considered roadworthy if the front tyres are not of the same brand. Currently, due to financial reasons, all 4 of my car's tyres are from different manufacturers but all of them are the same width, profile and rim.
He now also called me a double retard (in a friendly way, mind you) because recently I busted my front left tyre after driving up on a sidewalk too quickly and replaced only one tyre with a new one, instead of replacing both front tyres since I will need that to pass the rego check anyway.

Also, does my emergency tyre is really REALLY bald. Would that pose a problem on both a random police check and rego check?

I am in NSW, my car is 2000 Corolla.

Thanks in advance.

From my understanding, this will damage your car as time goes. I am no car expert but my logic simply says that having tyres of different thickness will put pressure on some parts of your car to accommodate for the difference. Happy to be corrected.

There's no legal requirement in NSW to have matching tyres.

Spare Tyre: The RTA guidelines require that your vehicles tyres must be in good condition with a tread of at least 1.5 mm in depth across the tread surface.

You can probably get a suitable spare tyre from a wrecker for $20.

  Well, yes and no. While there is no hard and fast rule on on brands, tyres must be the same construction, size and track…
  
  From the NSW RMS tyres handbook:
  
  All wheels and tyres fitted to an axle must be of the same carcass construction, diameter, offset, width and
  mounting configuration (except for spare wheels used in an emergency situation).
  
  Don’t mix tyre types or sizes if you can possibly avoid this. Never mix radials with cross-ply tyres on one axle. If you have only two radials, they must be on the rear wheels. Always make sure that both front tyres and both back tyres are the same.

Your friend was probably told this when he wanted one or two new tyres and got duped into buying a new set of 4. I was told the same thing by a place that specialises in tyres however after looking it up online found out this was not a requirement and got a single tyre from the wreckers and got a roadworthy certificate without a problem (in vic).

There is nothing compelling you to carry a spare at all, nobody cares what condition it is in until the rubber hits the road.

  This. I deal with plenty of new cars and the amount of new cars that come out that dont even have a spare tyre. It's usually Euro cars. What they have is a bottle of goo and a compressor… great for a nail puncture, not so great for hit the curb and bust your sidewall…

Cops aren't going to check the tyre tread on a Corolla unless they catch you ripping a burnout or your car looks like a complete shitbox.

The only problems with non-matching tyres on the front or back, will be is if one is a cross-ply and the other is a radial. I know its dangerous, but I think it is also illegal.

I also believe the law states that you don't have to carry a spare, but if you do it must have legal tread.

Keep in mind that the law is different for each state, so research is best.

All you need is tyres with legal tread to pass. Only this year I had two cars pass with tyres different front to back. One had two different tyres on the rear. All of them were the same size though.

Having a pair of the same tyre on the front or rear is better for handling. Having different tread on each side of the car can adversely affect braking. One side may have more grip than the other causing veering to one side under extreme braking, or handling corners differently left to right.

Having all four tyres the same is only really necessary for true AWD cars like Subaru, not ones that drive one end all the time and the other end when traction fails like Honda CRV. In AWD cars it can prematurely wear the centre diff. Which is an expensive exercise I found out in my Subaru.

Buy another new tyre the same brand of the front left one you have just replaced.
Have it installed on the spare rim (the one with the bold tyre) and put it at the front right.
Put the old tyre that is now at the front right as spare.
With minimum cost you now have a safe car (front wheel drive likes good front tyres and also great for breaking and handling) and a safe spare just in case.

  This.

    Yep, this exactly. What maxi said is exactly what I would do. Take the worst tyre off the car and use that on your spare and buy one new one to match the newest one of set already on the car. Also, always try and put your best tyres on the front, even more so in a front wheel drive car…

  I was recently thinking the same, looks like this is the best way to go.
  Thanks!

Why would you ever get tires that are different profile and width? thats retarded. Best off buying 4 decent tires of the same profile/width. And replace both tires if you bust 1.
