Nankang NS2R Tyres question

The NS-2 took me to victory a couple of weekends ago on a dry to wet track: http://youtu.be/NZJc1wK7Hfc?t=8m10s

Look from page 12 for the lap times in the race. It only got properly wet about lap 10.
Quick in the dry, only 0.7s off the AR-1 and in the wet they were awesome. Communicative, kept their heat, no aquaplaning and were progressive with slip angles.
Dave will be pleased to note they had loads of tread left on them when I finished!

For my education, I don't race in the UK, so not sure of practice, but how can the scrutiner look at tyres? I wouldn't dream of driving my car to the scrutiners box with the actual tyres I intend to race on, I keep an old set for that sort of thing, if I'm in the end pit it is nearly 2km to drive to the other end where the scrutineering is and the back of the pits road is covered in rubbish marbles etc.
The series I race in are open on tyres but has a width limit, that is checked by the series organizer, who is around the pits the entire weekend, I'm sure if I put something to wide on the rack he would pick that up.

Yeah, come to think of it why would a scrutineer check the tyres. They are there to make sure the cars meet msa safety requirements, not the race regs...

Race regs are still checked by scrutineers, just at a different time. When you come in to parc ferme and you dont have any tread left you could very easily be excluded. Never seen it happen mind...Thurbs said:

Happened last year with 750 at Oulton, one guy got (wrongly) excluded because the labelling on the tyre was slightly different from the description in the Blue Book, this was overturned on appeal. I've also seen a front running car excluded this season for going out on wets when they should have been on list tyres and I've seen other cars caught trying the same prior to the race - they were just reminded of the regs and did arrive at the grid on the correct rubber.
ETA, just re-read what you wrote Thurbs, I haven't seen any biffed for tread either

Meant to ask were you using the 100 treadwear compound? Timings: http://tsl-timing.com/file/?f=CSCC/2017/172964fuc....

We (as in the BMW Compact Cup) use the NS2R, we use the 180 compound. It seems counter productive but its actually better in the wet than the softer compound. Tread blocks don't move around as much under braking/cornering so disperse water out a bit better. Same reason applies to the dry. However also worth noting we don't allow tyre shaving so this makes a difference. If you are allowed to shave them then the softer compound maybe better.
The M3's use the harder AR-1, the 330's too!
