If you must have tyres today, you're probably stuck with what you have there.

However, if you have time to wait a couple of days for the shipping, go to http://www.vulcantire.com and get a set of Falken Ziex 512 in size 205-50-15.

You'll spend less money and get a much better tyre.

You'll be surprised how well they handle in the dry for a design that's also so good in the wet winter.
