Folks, Just got myself a 2yo Triton dual cab GLS, tyres are on the lean side.

The tyres are down to the wear indicators, but the tread depth is still aprox 3mm on the front tyres and 2.5mm on the rear. I have read min legal tread depth is 1.6mm. Other sites say once the wear indicator shows they are classed as illegal.

So are my tyres legal or not?

Any sugegstions for a a good HT tyre 265/70 16" ?

Thanks Zane

next silly question - the tyre wear indicator - the little bar located around the tyre - should this change colour when worn? Or simply become fluch with the tyre surface?

If it's flush ... the tyre is unroadworthy.

I wouldn't worry about trying to get the absolute maximun legal wear out of a tyre, since when it gets this low, the tyre performance is well down. Braking & handling have already deteriorated. It's more susceptible to punctures and damage, and isn't as good off road either (exept maybe for sand).

From a tyre performance angle, I believe the police renew tyres at about half tread (if I've been correctly informed?.

Having said that, the're a pretty dear item, so I know where you're coming from.

The tyre (any tyre) for use on a road must have a clearly definable tread across the road contact surface of the tyre. e.g. if the tread is worn off the shoulder, regardless of the depth of the remaining tread, the tyre is u/s

Hello - 1.5mm in WA (apparently) - have been lead to believe you need 2/3rds of tyre at this level.ie just having one section (eg tye shoulder) below this level is Ok (and from what Ive seen around normal!!)...but could be wrong.

As mentined not a good thing to let your tyres get this low anyway ...especially in winter.

Just had a roadworthy done in Qld. The guy said that the tread wear indicators mean nothing legally. He said he had to measure the tread at the lowest point. He also said that the tyres that have deep tread in the centre of the tread area but shallow on the shoulders mean that the tyre is buggered once the shoulder wears down to less than the legal depth (I think 1.5mm?) regardless of the depth in the middle.

However as others have said, once the tread is that low your tyres will handle like crap anyway. Buy a second hand set if you need to.

As I am a pink slip inspector, or authorised examiner in NSW the legalities are,
"If any part of the tread is worn down to 1.5mm the tyre is not to be passed for rego. If the tyre has any deformatives such as bubbles, cuts, damage to plys the tyre is not to be passed".
In answer to your question 1.5mm in NSW. The wear bars mean nothing.
