Two of my tires are totally worn and need to be replaced. And now I got a nail in one of the two remaining good ones...except it ended up being 4 nails and the tire shop said that is too many holes to repair.

So I have one good tire now (maybe 50-60% of life left). Would it be dumb just to replace the 3 instead of all 4?

I have a Fuzion ZRi, new tires will be Firestone Firehawk Wide Ovals (probably the Indy 500 version).

 

I an word....Yes. If you have to buy 3, the fourth is not that much more. The new Indy Wide ovals are only about $160 a piece.
