Tyres maked "inside and outside"

Which ones, A008s have a very different outer shoulder to inner shoulder.

I'll have a look in the morning. I asked for two second hand rims from the scrap yard and they arrived today with these inside/outside labelled and well worn illegal tyres on them.

I wanted the rims not the rubber so for £10 I am happy but curious.

The tread pattern is asymetric, but not directional.

may have a kerb rubber

Good point.

With asymmetric tyres (an inside and an outside), there's something different about the tread, tyre structure or the rubber compound between inside and outside parts.

Tyres with rotation markings are directional. If directional tyres were asymmetric as well, you'd need different tyres for left and right sides of the car.

An asmetrical tyre is often harder-wearing on the outside part of the tread. The old Michelin XAS had more rubber there, so the outside had a chance of not wearing out first. It was the first mass-market asymmetric tyre - in the 70s IIRC.

And if they're directional, asymmetric and different sizes front and rear like many top end sports cars you need four different tyres.

Which is why they have no spare wheel !

I went out with a girl once who had C+A on her knickers. She thought it told her what way round to put them on.

If there is no other reason for a tyre to be "handed" then it will almost certainly have kerb rubbers on both sides. To do otherwise would create a fitting issue which no doubt many tyre fitters would fail to spot and which would then create an MOT fail for absolutely no real reason because the kerb rubber isn't a safety issue.

Only if a tyre is either asymmetric or directional would it then be sensible to have the kerb rubber on only one side.

The strange thing is that tyres with kerb rubbers DID only have them on one side. Maybe there would be a problem with an inside edge kerb rubber fouling a/r bars or similar. I have not seen them for many years, so they are probably just for the classic market if they still exist.

Michelin Pilot Exalto currently have kerb protection rubbers on bth sides I've used them in 45 and 50 aspect ratio recently so hardly classic market.

oh, well, just goes to show. The last ones I had were on my Zephyr 6 in the mid 70's.

I had a Zephyr 6!!!!!!!!!!!!!!! Colum change and big bench seat?

On its umpteenth block and gearbox with only the rust holding it all together? The anti roll bar ripped itself off the chassis on my one.

Is the back seat any reflection on your addie - Mr Pounder?

It did when I got it !! I installed a Jaguar 3.4 with floor change manual box, so I had to install two front seats (possibly from a Mk4 Zodiac (I am not sure now) The handbrake was the big problem as I had to remove acres of bulkhead and dash so the umbrella handle affair had to go. I used a commer van handle on the right and made a strange agricultural linkage that went underneath , worked enough for the mot. !!

mine was OK rust wise and at the time was only ten years old, I only changed the engine to fit a larger one. We had several of them as hire cars and they were better than most on reliability.

the bench seat was in the front as well, which meant you could take 5 passengers with ease.
