Nankang Ns2 Tyres

The Traction, Tread wear and Temperature ratings on tyres come from a US Federally mandated test regime.

If the tyres are to be sold in the US, they must have them.

Traction is an artificial WET traction test where the tyre is run through basically a large puddle (cant remember the speed though).

It is a measure of resistance to aquaplaning.

Temperature is a measure of the tyres resistance to damage caused by continuous high speed running.

It is tested by mounting on a machine which spins the tyre at various speeds and internal pressures against a rough roller which varies in surface temperature. The force of the roller vs tyre can be changed too.

Therefore a 2000kg car doing 160kmh for 6 hours in the Arizona desert at 85* road temp with a slightly underinflated tyre can be simulated if required.

Of course the test is actually standardised.

The tread wear is also from an artificial testing method using computer driven machines.

It is used more as a measure of tread hardness rather than mileage.

I'm on my second set of NS2's now... had the last set on the coon for 2 years... including some burnies and 1 skidpan, did near 40000km's on them, and they probably would have lasted another 6-12 months had the camber problem I encountered not chewed the insides down to the belts.

they still had 30% meat on the middle and outer edge.

during the 2 years they were on the car, I never lost grip or traction in the wet or dry (except if t/c) was off and towards the end I pushed them really hard on some wet days to see if they would break free they didn't... started to get a bit under steer-y in the front on their last days though, but they were completely bald on the inside edge.

I've heard of some cracking side-walls, as was suggested take them back and get them swapped.

I'm all for get what you pay for, and when it comes to 19" tyres that all seem to last about 40-50000km's that range between $200-$1000 a tyre, for me it's about longevity, then price, then performance, and the NS2 has met all those criteria.

I'm not saying they are the best tyre - by no means... they suit me, my driving style and my budget.

I have 245x45x17 michellin pilots (PS1's) and they won't see 20,000kms. Some spirited driving but no smokey burnouts, track work, or 1/4 mile runs. I found they wear quickly and are no improvement over the stock dunlop SP3000's, traction wise. They also lose traction very sharply in the wet, whereas the dunlops were far more predictable. Not a fan of these PS1's. I'm getting 19's soon and are debating on my choice od tyre.

The PS1's wasn't the best tyre out there, which is why Michelin replaced it with the PS2.

Ahhh that makes sense cro cos I hear the PS2's are very good.

Cheers.
