Hello,
I've got a '97 Cooper with the standard alloy wheels (minilites or Rover's lookalike I believe). I have a slow flat on one so have been reading up on tyres (preparing for being told it's not repairable!)

Currently the tyres are 145/70 R12. There doesn't seem to be much choice for that particular size, most of the 12" tyres seem to be 165/60. Could I change the tyres (presumably all four) to this size instead? What are the (dis)advantages of the wider (shallower?) tyre?

I've had a quick read of the wheels / tyres FAQ as well as having a search, and while there's some great info it doesn't seem to answer my question.
Oh and sorry if it's a really obvious answer and I'm just being stupid!

The 165/60x12 size is absolutely ideal. The road-holding will be improved also. However, don't buy those 'cheapie' tyres. Go for a good brand like Falken or Yokohama. You'll love 'em.

Yes do it!!! Change them all to 165/60/12's as soon as possible, it's by far the best modification I ever made to my mini . You'll notice a big difference in grip and road handling over those standard skinny 145/70/12's, I couldnt beleive that I was driving the same car after I fitted mine!! (keep the 145/70/12 on your spare though, as it fits in the boot under the petrol tank much more easily than the 165/60/12 does!)

Its more than likely the bead on the wheel has corroded and leaking.

Thanks for the replies - time to put some pennies aside and get them tyres changed! The tread's ok on the rest of the tyres so I might get some use out of first.
I wasn't sure what flexibility you have on car tyres with width / profile. I'm used to bikes (push bikes) you see, where the only issue is the handling really.

That's useful to know - is that easy to fix? It sounds like it'd just be a case of cleaning up the corroded area, would that suffice?

Most probably, clean it up with some sandpaper, put some bead sealant and jobs a goodun
