205/75/15 OE
215/75/15 1 step up
225/75/15 2 steps up
235/75/15 3 steps up Stock for many small suv's/trucks

Can also go wider and maintain OE height with
225/70/15 Stock size for Ford Escapes. I did this with mine and it cornered soo much better than oe.. I used continental truck/suv.

Or go a tad higher and max width on stock rim with
235/70/15 won't find an suv/truck style tire. this is usually a street race tire size for hot rods

simple tire size math.. 1st oe numer is 205. that's 205mm tire width. the next number is 75.. 75% width=sidewal height. the 15" is obviously rim size. so to go from 205/75/15 to 215/75/15 is 1 step higher and wider. 225/75/15 is 2 steps higher and wider. 235/75/15 is the 3rd step higher and wider. All threse will work. 235/70/15's rub on mine (just hard turns/bumps.. livable), but that's cause they are mud tires.. same size in an all-terrain probably would clear.
