GR Yaris GR Yaris Tyre Wear

This set up and 32F 34 R tyre pressure has worked very well for me . Round Aus on all surfaces and in my track fun .

That's a surprise to me. I would assume the F1 SSs would last longer than the PS4Ss.

They will never as the (American system of ) tread wear is higher on the Michelin 180 as opposed to, I think, 150 on Goodyear.
There more than black n round!

It was my general sense based on videos & posts like:
I ran the PS4S tyres for 10700 miles, before I was asked to review the Goodyear Eagle F1 Super Sport tyre for the last 10000 miles.

I've still got the F1 Super Sport tyres on and they still have life in them, which is quite impressive as they did a full season of sprinting and a half track day ...

... with my F1's getting towards the end of their serviceable life with 4.5mm still showing...

which made me ask further above, as I would assume that a tyre that made it to 10k miles, after a full season of sprinting and a half track day, with 4.5mm still on, would last more than another 2k miles.

Ahh, now I understand where you're coming from. My understanding is that the Goodyear Eagle F1 SS is better with high heat applications like on track - which then in turns means less wear if you're using them like that. I don't think that you can really apply that to road usage though where the tyres stay in an entirely different temperature window.

My tyres needed replacing front and rear at 6k driven in track mode 100% they had 3mm left in the centre and worn on the inner edges. Getting cup 2 connect fitted next week

Were these stock tyres?

Any particular geo settings?

What % of road vs track miles?

That's...not a lot of miles.

I drive 99% of the time in Sport and my summers came off at about 6.5k miles and were still fine, front and rear, with even wear across the tread and plenty of life left in them.

I'm still running the standard geo though. Have you adjusted camber?
 
Mine wear like that, inner edge gets the pain. I have 2.5 deg of front camber, and a slight tow in front and rear.
I’m not convinced about the benefit of steering feel vs tire wear. Although I’m fairly sure on track the setup is better and results in less sidewall scrubbing, as if it’s the road driving that does the damage.

Very useful and thought provoking insight (y)

Your camber setting is nothing extreme, but it's probably the tow that causes such tyre wear anyway (or at least most of it) .

How much tow have you got and is it in or out?

I have 2.5 degrees negative camber on the front but parallel toe. They seem to wear pretty evenly.
 
Can you guys help me out please and give an opinion on the front tyres? Picked mine up today with 1250km.

Is that tyre wear normal and acceptable or am I to sensitive here.

Thanks

Tracked - as in driven on one a few times?

I asked and it was said no. Just thought that it looks a little excessive for that low mileage.
What do you suggest? When driven on the track with that low mileage I suspect it was not well run-in?
Feeling a little bit insecure now o_O
 
not really happy either with that PS4S wear but it seems to be soft from the structure and does not take too well any harder driving.
