I've just bought these tyres and although they aren't directional they have "inside" and "outside" stamped on them. So in the pic they are how they will be across the rear axle. My worry is that the treads are opposite of each other.


Is this correct?

If that's how the manufacturer intends, yes absolutely.

Another case in point - Vredenstein Ultrac Sessanta

Surely they are directional if they have inside and outside stamped on them????

They're both asymmetric and directional.

Then of course it matters which is inside and which is outside.

What if the rubber compound is different across the width of the tyre??

Consider that tyre. You want to fit a pair of them to your car. The tyre is not going to have "outside" stamped on one sidewall of the tyre, like the tyres in the OP. Whichever sidewall is inside or outside is irrelevant, as long as the tyre rotates in the correct direction.

That was my point. You see what I mean?
Indeed I do, but your comment when in reference to the tyres he bought is not correct, the direction of rotation and inside/outside being correct are tied together.

My comment wasn't in reference to the original post. It was in reference to the post i quoted, hence me quoting it.

No, if they're directional, it doesn't matter which side is inside and which side is outside, it matters which way is forward.

Ok this is getting silly. hehe

I spoke to Toyo and it's fine.
Marfs second post shows an extreme circumstance where it just doesn't "look" right but it is.

T1 Sport

As others have rightly said, they're asymmetric not directional.

There are very few asymmetric directional tyres on the market, certainly no mass produced tyre is.

Is it me or has the price of rubber gone through the roof?

You've completely lost me.

To me, a directional tyre, does not have "inside" or "outside" stamped on, a la Eagle F1, Toyo T1-R, T1-S, R888, etc
Perhaps not inside/outside, but they are idiot proofed wink

That looks like a pair of passenger side tyres (or drivers side)

Rather than an Axle pair, you'd expect there to be a mirror of the tread pattern on axle pair.

Yes!

My front tyres which are 195/50R15 T1R were £35 each when I put them on two years ago, they're more than double now!

Let us know if the sidewalls are as squidgy as the T1R!

I have T1-Rs on there now so I will report if these are better. smile

This is what I was worried about, but if you see Marfs second post it shows it not to be the case.

Cool smile

Slightly academic for me as Toyo don't seem to do these in a 205/50+225/45 R16 which is what I need for my new wheels.

Indeed they are.

Also known as 'composite' tyres.

They aren't directional, they can go on either side.

They are directional though, in that they are designed to rotate in a given direction. There'll be an arrow on the "outside" of each tyre to indicate the direction they rotate in.

P6000 for instance are not directional and can be fitted whichever way round.

There's no arrow, if they are fitted on the N/S they rotate in the opposite direction than if they were fitted on the O/S. But both ways is fine.
