Hit something I never saw in a travel lane (like a brick probably) and pinched my front driver's side front tire sidewall. Have a used tire on there as a temp (no Contitourings in Las Vegas--have to order). Car has 20k, and it actually looks like there's about 60% left on the remaining tires. I never intended to replace with Contitourings.

Question:

Do I order a $260 Contitouring and replace the front right only; or
Do I replace all four with W rated tires that I like and can knock down for $150 each.

Sucks to trash three tires with half thier life left. Also sucks to buy a new tire at the expense noted and only use it 1/2 way. Opinions or other suggestions?

Thanks.
