I just bought a set of Chengshan SportCat CSC-01 8ply 195R15C for my van. Got them for 2.8k each (with balancing and tire weights) from Mindanao Tirehaus... very good deal....Ok naman... very quiet tires, you can already tell by looking at the tread pattern... its smooth and has performance tire looks... Ok naman din ang grip... rubber doesnt seem to be stiff or hard... (parang Toyo tire softness in my opinion)...comparable rin naman to branded tires. More importantly its DOT rated/approved and its an ISO certified company so i dont worrry on its safety. Also i dont drive like a madman naman so ok lang budget tires.
15 years user na ko ng Westlake. Dati sabi rin ng iba pangit dahil China tires but after using several sets on various cars... had no problems or issues whatsoever. I have also tried Sailun and Durun tires before. Ok naman din.... no issues.
Pangit pa mga Goodyear ko dati in my experience.. madali ma-oblong. Yung mga dating Dunlop Lm001 na 195/55/15s madali naman mapunit sidewalls. Toyo tires naman on Grandia namin madali mapudpud agad.
Did a little bit of research... Chengsan has joint venture with Cooper tire (US brand) since 2006... known as Cooper-Chengsan Tire Co. Ltd.
Chengshan Tire
I have to admit though, sometimes i research the brand AFTER i buy... hehehe... but so far ok na ok lahat ng nabibili or na-ta-try ko. ;)
