Chinese Runway Tyres
Discussion
I had three buckled 16" wheels on my TF and just bought a set of secondhand wheels with practically new tyres.
The rear tyres are a pair of Chinese made "Runway" tyres. They look new but could just be made of granite.
Does anybody know about these? Am I about to die?
Maybe I should take it on a trackday to find out what they're really like...

I thought I'd seen elsewhere that MGF/TFs (don't forget there is a much earlier TF model) were tyre sensitive
a tyre may work on a car but the correct tyre will work very well, on the same car and the difference can be night and day
'new' tyres with loads of tread can be be quite old and hard through age and lack of use
tyres, good or bad, effect the braking, steering, roadholding, ride comfort and noise
after brakes they are probably the most important components on a car, four small patches of rubber that are the only contact with the road, without that contact the car's electronics and driver's skill aren't effective
The TF is very sensitive to tyres. When I bought the car it came with a couple of unknown Japanese tyres on the back, different makes of course. Oversteer was very easily provoked but not so easily predicted. The correct Goodyear GS02s improved things but not nearly as much as the Toyos.a tyre may work on a car but the correct tyre will work very well, on the same car and the difference can be night and day

I reckon the best idea is to get the car on an airfield and slide it about; just in the name of safety.

sounds like you are going to test these tyres to extreme so can report back on them 
money to burn or at least smoke
I don't want to find the limits on public roads. Had enough of that with the unknown Japanese tyres that came with it.money to burn or at least smoke
There's a track evening at Cadwell coming up but that's not got the runoff to really push. I'd do it in my Locost as it's pretty easy to catch and drift but the MG weighs twice as much, has the engine at the back and these tyres really are a journey into the unknown. I don't want them to be a journey into the armco...
If they come up OK I won't test them to destruction.

Sir, to test your tyres I offer you this link - Curborough all day tack day - 1st August £80 per car all day
Looks good. There are also some evenings coming up at Brands and Donny. Evenings are good as they're cheaper and I don't want to stress the car too much. I've already got a track car which can take it far more easily.
The MGOC workshop seem to have used airtools to refit the wheels. Even using a 4' long steel tube as an extension I had to pull pretty hard. One wheel nut just won't come off.
Taking it into the tyre fitters with one Toyo and one Ringworm tyre on the back to see if they have any more luck with that wheel. It's just a little bit skittish...

I ran the car with both Runways on the back for a bit. They were in good condition when they went on, I inspected them as did the company who sold the wheels; an Elise motorsport specialist who buy written off MGs as cheap source of Elise bits (the dozen or so race spec Elises outside confirmed this). This car had been vandalised rather than crashed.
At first it was a pleasant surprise, the dry grip is a little lower than the Toyos but not bad and quite progressive. The back end would gently drift out and easily corrected on the throttle or a quick dab of oppo
Unfortunately it appears they've started cracking up within the tread and sidewalls on both tyres. It looks like they're de-laminating. This was with fairly brisk but safe road use.
Obviously I haven't driven the car since spotting this and I'm replacing them today. Just wondering whether or not to report them to the vehicle inspectorate.
The moral is: Don't buy Chinese tyres.

I agree with the moral of your exercise/story; We should indeed be careful of things made in china. Frightening, the abysmal quality of all products that have been coming out of there for so many years.
No, I've got some Nangkings on the front of my A4 at recommendation of the garage (who also race in 750mc) and they are very good. But Nangking come from The Republic of China as opposed to The People's Republic of China....Seriously, the Runways breaking up were pretty nasty.
