Wanli's are supposed to be ruddy awfull, I'd just get rid of them. Had a look at the tyre reviews on Which recently, they gave the Wanli S1095 a rating of 10%, here's what the review said:
'The 195/65 R15 V Wanli S1095 offers acceptable dry grip, but wet grip is very poor in every test. In fact, we found that the Wanli S1095 was so bad at braking in the wet that it travelled nearly 20m further before stopping than the best tyre on test. Even though, like all the tyres we’ve tested, it passes all the minimum legal performance requirements, we recommend you Don’t Buy it. And if that doesn’t put you off, its availability is so poor you’re unlikely to find it anyway.'
