Switched to snows today - bad tire wear

[DunDan]

Off with the rims and on with the ugly steelies! Took my Yoko H4s off which have been on for <20K kms and only one is worn to the wear bars. The other 3 are in perfect condition. My question is after a new alignment, is it okay to replace only one tire?

[KJ-M3]

If the other 3 still have as much tread as you're implying, it should be ok. If you are worried, just replace 2 of the tires instead and keep one for a "spare" in case you tear one up etc.

But you SERIOUSLY need an alignment though. It sounds like your Toe in/out is out of whack.
