nankang tires??

I had a set of Nankangs on bullitt wheels on my V6 before I got my GT. At that time I was driving about 200 miles per day back and forth to school. I thought they held up very well. I got about 40k miles out of them, probably could have gotten a bit more if my alignment had not worn the edges of the front tires. I didn't have any problems with them at all.
 
wher can i find these tires?? i looked thru ebay and couldnt find the size i want, im looking for sumthing like 275/40/17, how wide are my rims?? you can see them on my avatar.. also, whats the widest i can go with with these rims.
 
I bought my Nankang tires locally, although I have seen them on ebay. The ones I had were 245/45 17. I'm not sure what other sizes the Nankangs come in. I believe your wheels are 17 x 8. The maximum recommended width for this wheel is a 255. However, some people go as wide as 275 with no apparent problems.
