32's - 638.6 revolutions per mile - ~8.6'/revolution
35's - 576.5 revolutions per mile - ~9.15'/revolution
My math says its about 6.6" diffference per revolution difference so
for every 638.6 revolutions (1 mile on your odometer) you've traveled 9.15 feet on the 35s or 638.6 * 9.15 = 5843 feet or 1.10 miles. Roughly an extra 600 feet.
Edit: Assuming your revolutions are correct...

I used this furmula to figure out -
C = 2 pi r for the circumference. They are 63,360 inches a mile. Maybe I could be wrong...
