Pug

I ran over a spark plug with my relatively new PS2 (~3000 miles). It did enough damage that Costco is ordering me a new one (1/2 of the plug is sticking out of the tire - but it still kept enough pressure for me to drive about a 1/2 mile to a parking lot to change it!)

The Costco Tech indicated they would measure the tread on the damaged tire when the new one arrives to calc what I owe in the difference.

Has anyone gone through this with Costco yet? I'm trying to see if this is straight forward, or if I need to be on my toes dealing with this. (It's the store in E. Hanover NJ).

Thx
