Stretching tires and height of sidewall
 
Would stretching a tire reduce the factory sidewall height? For example would a 225/45 tires stretched on a 9.5" wheel pull the tires to something less than 45% of 225?

So if I wanted to keep the OE recommended rolling circumference then I shouldn't stretch? Is the difference signifcant?

yes, I've got 18x10+25 on 225/40/18 and they fit my rear fenders well with a slight roll.

If you like the look, do it. Anything under 5% difference is considered acceptable.
