Cannondale Bad Boy - tyres and bottom bracket

Hello gents

First post here so go easy on me. I commute to work on my bad boy and its been great for the last 2 years. I've just replaced the chain and cassette due to wear and it was looking like it would die any second. I also replaced them because of a clicking noise when applying pressure to the crank/pedals... but after riding into work today, the clicking noise is still there(even though the gear change is sweeter and the ride smoother)... so I guess I have to change the bottom bracket.

Problem is I don't know the size... I am pretty clueless on the technical side of bikes.
The guy at the shop said I have to take it out to see, but I need it for work... Chicken and egg situation. Does anyone have any ideas what size I need?

Also I have a problem with regards my front tyre. For some reason it has deformed and has got an annoying kink in it, making the front wheel feel like its egg shaped. I only want to replace 1 tyre but cannot find 700 x 28c Maxxis Detonators anywhere... Any suggestions if I can get them anywhere or whether I should swap both tyres for something else?

Any help or advice greatly appreciated.

    You can mix and match tyres, should be fine. I have a 23mm front and 25mm rear on my Trek and it rides well.

    (It's definitely the tyre and not the wheel itself with the problem, you're sure?)

    Don't know if you have seen this site already, but its a good first stop

    Regarding tyres, I use 700 X 32 Schwalbe Marathons on the rear and 700 X 30 Schwalbe Marathon Racers on the front

    Cheers guys.

    I can'tr see anything wrong with the wheel at all. It looks both true and free of dents.

    Any ideas on the Bottom Bracket?

    It could just need a clean. Or it could be the cranks/pedals rather than the bracket - linoue's link is gold for trying to figure it out.

    Thanks for your help guys. Tonight I took it to see a mate who is into his bikes and fixes alot of them. He initially thought it was the crank that needs tightening... so we did that and it still creaked/clicked. We then tried some different pedals and it still creaked/clicked...

    I am going to give the bike a damn good clean and lube then try again.

    Next job is a new BB for £13.

    Can anyone suggest a good lube for re-assembly?
