OK, to answer all the Q's.

Datestamp 2313, so little over a year since manufacture.

Pressure, 32 PSI. They have been run harder when carrying load, and are noticeably skittish when run hard with no load, as are all tyres. Looking at wear pattern (these have been on the rear), this is still overinflated.

These are driven less hard than most tyres I've had due to lack of grip and a desire not to end up on a kerb going around Milton Keynes.

There does look to be a brown discolouration around the area where the tread meets the sidewall, maybe a telltale of overheating? If they have overheated, given the very limited number of times I've pushed these tyres, I suggest they are unsuitable for the Omega.

94Y, GM state 93

The brown(or sometimes blue on softer compounds!!!! ) is exposed worn tread that's unused.

So that would fit with enthusiastic driving, by you for example. Followed by more sedate driving for some time, by Mrs TB for example, where the exposed worn tread has been exposed to the elements. Sidewalls and other parts of the tyre that are exposed but not brown, and not in contact with the road will still have release agent on intact.


Brown is sometimes visible on sidewalls that have been scuffed on a kerb for example.

Personally I won't fit anything less than 97 load since the F f fer FALKEN disaster. Or at least the highest load available by that manufacturer.

Every Dunlop I've had has been 94 or 95 (depending on model).  Only ever seen this cracking on those Heinz 57 from your car, if you recall those?

[chrisgixer]

Are you sure they haven't run a bit flat at some point...?


....and you mean Tunnies car.

If they have been on the rears and driven hard from a standing start whilst soft, then could it be torque destroying the insides of the sidewalls

Be interesting to see what state the inside of the tyres looks like...

How does the sidewall construction compare between the Dunlop TT/RT and the Goodyears that might answer the conundrum...

Remind me to punch Jon next time I see him. Another fickin pointless tyre thread.

Never below 30.

Never below 30 mph.

You're not wrong

My average speed over the last 500 miles has once again dropped to almost 20mph, due to breakless morons not prepared to get anywhere near a speed limit.

The Dunlop And Goodyear web sites are almost identicle. As are the sizes available, and the suppliers. They are almost one and the same. Branding and models are differant obviously, but they do share technologies and resources. ....last I looked anyway.

Differant set up in the states iirc.

There must be summat fundamentally different for one to fail when tothers don't... nothing else has changed. Not the car, not the driver, not the driving

On top of that air bubble/blister on one of the 18s, I'm not really keen on having them on my Omegas again

I rekon he's run them flat meself. He's been very stressed lately, poor time management and all that.
