Hi

Firstly;
What is the general consensus about wear rates on tyres and having to keep all the tyres at the same level of wear? When I had my previous Scooby (about 6 years ago) I was advised to make sure all the tyres were roughly the same wear level or it could cause problems with the diffs.

Due to the number of roundabouts we have the left front will always wear quicker, should you swap from to back? When I did a search some people said yes others say no!

Secondly;
I notices this evening that on the driver's side rear wheel arch on my my03 sti there is a black rubber trim which pushes over the lip of the arch. This is missing on the passenger side. I assume its not vital but should I get a new one for the passenger side?

Cheers
Steve
