I agree with everything said in this thread so far.
The Linglong L688 looks a lot like the tread pattern of the Triangle TR968 tyres (another cheap Chinese brand) which makes me nervous. Triangle tyres don't have a good reputation here in NZ. Neither do Wan-Li.
On the other hand, I've been surprised by the very good performance of the cheap Chinese tyres that I bought, which are Westlake SV308 (the same tyres are also sold as Goodride SV308), 215/45 17. Really important to get the SV308 high-performance tyre and not the H600 or any other version...
They are quieter than the early-style Goodyear Eagle F1s I had before and seem to have very good grip, I never feel them slip on smooth surfaces and there's no sign of aquaplaning. Nice steering feel too. They were round and well-balanced and the rubber seems quite soft compared to other budget tyres.
I have driven on many expensive and many cheap tyres over the years, and I can honestly say that the Westlake tyres are the best I've had. The low price is just a bonus. I think sometimes you can strike it lucky. The tyres are TUV-marked and sold in Germany.

. 917 reviews and an average of three out of five isn't bad.
At the end of the day, you have to weigh up the difference between old, hard tyres that may have been top quality or a full matching set of new cheapies. I'd rather have the full matching set of Westlakes
