Any Info About These Tyres

[Teiresias]

So, here's the question, are either of these directional tyres?

If you've seen the previous thread you might know why I'm asking.

They're the tyres that came with the car, and I'll be getting new one as soon as I can save up.

Playz -PZ-1

Playz PZ-X

This is one of my PZ-1, both of them are cracked like this. Any comments?

The last picture where the tyres are cracked, is probably because they are old/hard. I would still use them, but I'd be aware of their condition when driving in the wet, they will offer a lot less grip than newer tyres.

Take a look at that link, you will be able to check their manufacture date and figure out how old they are. In proper controlled conditions Bridgestone guarantee their tyres for 6 years from manufacture date when stored in proper conditions.

The Bridgestone Playz tyres are from Japan, not released in Australia but they look similar perhaps to RE002.

That page on aging is awesome, thanks for that.

And yea, I know they're a JDM, Bridgestone f**king Victoria's HQ don't know shit about them, and everything on the net is in Japanese, so yea, really want to find out for now if they're directional at all for now until they're replaced.

Looking at the tread patterns, they're asymmetrical, they have an inside and outside.

Doesn't matter what side of the car they are mounted on.

Bridgestones adrenaline range is the same, as well as a lot of the higher performance street tyres you can buy.

It should have inside and outside printed on the sidewalls somewhere.

Although, being a jdm tyre, it may be in Japanese text.

My Supra had 10 year old Kumho tyres. (Cracked like that)

They don't grip.. Stock car I couldn't get traction in 2nd in a straight line lol. Just good for skids really..

I took them to the skidpan, thoroughly "warmed them up" then they started to grip a little... Still crap though, so just have fun

If you don't work it out. Just drive carefully in the wet.

My current tyres are from 1998..... Should have seen the tyre fitters face when they worked it out.

Grip enough but noisy as hell.

Old yokas with a 140 tread wear rating, must have been a good set of tyres back in the day.

Yea... Already crashed, about 7mnths ago... Twas wet (not raining), fishtailed, did a 360, went sideways over the curb, wasn't even going fast, 50km outta the corner, accelerating and I was already shitting myself as the wheels has been spinning all the way home.

Ended up replacing all the right hand steering. barings, both rack and pinnoins, possibly still need to to a baring on the left and the right hand drive shaft.

When I look at them both sets seem to have the triangles pointing in opposite directions when they're parallel, wouldn't that mean that they push water though the tread differently? Thus one side gets more grip than the other? Again I'm no expert, just applying my own reasoning really.

But yea, they do have an 'outside' word on them, I think it was the PZ-Xs that did, the triangles go on the outside.

[luke gtr]

Yep, just make sure the outside is to the outside.

A lot of tyres are assymetrical nowdays...

Dunlop 3000a, fast response, sports maxx

Bridgestone adrenaline, er300

A lot of the Pirelli range, and the Continentals.

Also, some of the higher end Goodyears.

And let's not forget kumho KU36.

Bridgestone RE55S is one of the few that are both assymetrical, and directional.

Don't worry too much about water dispersal, they spent millions on development, I think they would work as intended.
