is it worth the money or do they just cause more problems?
This is why I will never use wheel adaptors!
I know someone whose friend had a pair and he was driving on the road, down a long straight hill. My friend was following him. Wheel adaptor broke. 36" tire passed the jeep that it was on and smashed into an ambulance that was coming up the hill on its way to a call. He got sued hardcore and no longer has the jeep. They were lucky that no one died.
