pirelli sport demon 120/80-18

Hi, looking for the inflated diameter of a Pirelli Sport Demon 120/80-18 tire...I purchased one based on its list inflated size of 25.9 but I'm lucky if its 24.75 delivered, do you think it will expand an inch when inflated? thanks for any insight....

Depends on the rim width too....Will have different profile...So inflated may be a wider.

Yes, its a 2.5 X 18 rim, first 80 series tire purchase, just wondering if its common to grow and inch or more once inflated, hopefully so...thanks
