Tire shops may ask you for the tire size you're willing to run, such as tread width and the sidewall ratio. Depending on the look you're going for, you could run stretched tires or run tires flush to the rim.
Offset means really little when it comes to finding tire sizes, it's not necessary and offset is more for determining how it fits with respect to the car
Assuming you're running a 8" width rim, a 225 series tire would fit really good on it and for 10" a 265 or 275 series tire would be great.
In terms of sidewall ratio the larger the number the more rubber you'll see and will also affect the speedometer if it doesn't match factory tire circumference. I would recommend a 40 or 45 ratio if you're running 18 inch rims
Some options you can run for tires are:
225/45/18 for fronts
265/40/18 for rears
Be sure to check out a tire size calculator to determine more accurate tire sizing!
