Tyres

[Fast Eddie]

Afternoon everybody
I know there's been loads of posts about tyres but can someone help me with instructions how to 'search' for a specific thread or point me in the right direction please?
TIA

Thanks everybody. It looks like I'm doing the right thing by checking early due to availability. I don't need them for probably another 1mm

Yipper - lots of talk about 'Rolling Radius'.

How do I check that on my existing tyres so I know what to get?

Also does that assume the Rolling Radius on the current tyre is as per manufacturer spec?

Final Question :-)
If I need 2 fronts, should I replace the rears at the same time?
