BLK6T Member 305 Member For: 20y 7m 24d Gender: Male Location: Sydney NSW Posted 10/05/10 03:31 AM Share Posted 10/05/10 03:31 AM Hey all,Just replaced the rears (as is usual on a XR6T), I had some Kumho KU31's which have proved to be a very quiet grippy and overall a fantastic tyre.I opted to try the Kumho 37's (a newly released tyre) which rated to be slightly better according to Kumho. After having these tyres for 2 days, I HATE THEM. I have never had a tyre handle this way before. when driving over bumpy roads the car tends to pull in the rear and slide, it just does not feel right. Has anyone else experienced this? Traction is also very poor for a brand new tyre and having these tyres on the rear just makes me nervous, especially at speed.Anyway, if anyone is looking for new tyres I would advise not getting Kumho KU37 but would advise KU31's.Cheers Link to comment https://www.fordxr6turbo.com/forum/topic/68025-kumho/ Share on other sites More sharing options...

Wen you feel the sliding in the rear are you pushing it? Or is this all the time at posted speed limits on bumpy surfaces? Did the tyre shop align your car? Incorrect Toe settings can make a car feel very skittish and tram line quite badly...

Take the car back and get them checked. Link to comment https://www.fordxr6turbo.com/forum/topic/68025-kumho/#findComment-1006753 Share on other sites More sharing options...
