I can understand the shortage of funds and the need to save. This site will show the differance in tire size:
Tire size calculator
The info. shows the 235 55 17 has a circumference of 85.4" and the 225 45 17 has a circumference of 78.5". The 225 would make the wheels turn about nine percent faster if I figured correctly.
Can't tell you if that's good or bad. Should help you in a drag race.
MERRY CHRISTMAS and good luck on your decision.

Ray
