Tire surface condition and threadwear marker

[Ixat]

Hi, have been using my GR80 for 50K now. Rotated front to rear every 10K. Wear rate is even between inner and outer of the tire.

 

But the previous front tire which was rotated to the rear looks bald on the surface. But there's 0.6cm thread more before hitting the threadwear indicator in the inner tire as well as the sidewall triangle threadwear marker.

 

Tires grip well in wet and dry. Just a little noiser than before.

 

Its 1yr 8month old now.

 

Should I change based on the thread wear marker or just by eyeballing the surface?

 

Thanks!

as long as the lowest depth hits below 3mm change it

In most countries it is an offence to run on tyres with less than 1.6mm tread depth.

Bottomline, if you feel unsafe, just change it coz it the only contact with the road surface.

The grip in dry and wet feels good just like before. Tested on a safe road.

 

Just happen that my friend changed to a new set of GR80 and compared against mine, mine looks bad.

 

My tire mech said another 20K at least before change is required.

 

So tats a little confused.

 

Thanks!

Besides... tyre so cheap....

U need a Depth Guage to measure the Tire Thread.

Would you want to go to the extend to measure the

Thread Depth?

 

What about having uneven tire surface which is caused

by Rubber hardening which our naked eyes cant really detect.

Heard someone ever mentioned that 40-50K mileage is the

average usage for a set of tires. Anything more is

 

For me, I will change tires every 1 1/2 yrs or 40K of usage which ever

comes first. Unless I change car in the middle of the tire usage, else

I will stick to this protocol. Really like the feeling and shiokness of

having new set of tires everytime I changed.

You need a depth gauge preferably a digital one.

[Yeobh]

On the contrary uneven wears and cupping can be very easily detected by just running yr palm along the surface.

[Jazz]

As long the mechanic confident to say 20K to go, just save your money and drive carefully.

[Akula]

50K mileage, time to change.
