So all the advice is to use NSR tyres for your fast cars, but when a packet of 4 Supergrips contains the following three examples, you have to question their manufacturing methods.

I can't remember where I bought these from, but the fact they even made it into the pack puts me off spending my money with them.

So it would appear that NSR are having some serious issues with faulty tyres. Even the new super grip (grey tyres) have considerable mold defects and dags, the response from NSR has been to return for refund, though the return postage negates the refund... 

The grey tyres true up great and run great, the only thing I've noticed is as the tyre wears the holes and other defects are getting bigger over time. 

What's the fix for this? Well NSR need to inspect their tyre molds and injection machinery to get a handle on this before further damage is done to their name and products.
