will a 255 series tire work? on my car and bolt pattern is 5x115 right?

255 may be a bit too wide, really depends on rim size also. yes thats the right bolt pattern

255s will take some modification inside the wheel well.

245s usually fit with no problem.

check out a tire calculator to figure out appropiate sizes to keep ur speedo close

I had a set of Goodyear GT+4'* installed on my car before (just moved to a normal size aquasteel for the winter, new 18'* come spring). The ones I had were 255 50R16'*. They fit, but at full lock in the front they would rub the plastic inner gaurd between the frame and the tire. In the rear the welded lip had to be pounded back (lip between the bottom of the trunk and the inner fender wall) to avoid sliceing the tire on suspension compresion.

The grip and cornering I recieved from the wider tire was amazing. I hope to get a comperable width tire when I get my 18'*.

with 18s i'd go with 245/45/18s

someday...someday

i going with 20'*
