Recently I changed all four tyres for Falcon 452's which seemed good value and had good reviews. After getting them changed straight away there was a LOUD rumble which I presumed was just the new tyres, I read that they were a bit louder than the Pirelli's so thought I'd give them a bit of time to run in.
After around 3k miles the rumble certainly aint getting any quieter and I think its getting louder.
Now a loud knock has appeared when going over bumps, but only intermittently - happened 4 times in a mile last night but only once today in 25 miles.
Thought I'd do a bit of investigation and there doesn't appear to be any slack in the bearings up/down or left right, but the tyres are worn down to almost bald over the first inch or so on both fronts, rest of the tread looks ok, and the rears look ok.
When I slowly spun the hub back and forth I could hear the bearings (I think) take up with a little click.
As a bit of background, I've had an intermittent squeak from the front which I thought was the pads, but I changed the discs and pads a while ago. I was told it might be a wheel bearing but ignored it as it didn't happen very often, and hasn't happened since the tyres were changed.
I've read on the threads that one forumite was advised to get all 4 wheels aligned and change the tyres to cure the noise and inside tyre wear. Would this explain the knock or is wheel bearing a suspect?
And is wheel alignment the same as tracking?
Any help or suggestions appreciated!
All this just when I thought for the first time ever it was running perfectly
