Can any one confirm is the rolling radius (give or take tread pattern variations) the same from 7.50 r 16 compared to 235 / 85 r16
I have a cut in a side wall and am looking at using a 7.50 as a spare the rest of the car being 235 / 85 r 16's

Talking to myself is bad form I know but found the answer here,

seems to depend on the tyre tread, the Commercial is bang on the same rolling radius and another as 12mm difference, negligble I guess given undulations on a road surface warping tyre walls anyway.

Michelin's figures for the same tread pattern (O/R 4x4):
235/85R16 2442mm Rolling circumference 363mm Static Laden Radius7.50R16
2450mm Rolling circumference 373mm Static Laden RadiusThat's insignificant to my eyes.
