There is no option for a 1:1 ratio ird, assuming you mean 1:1 ratio of front/rear wheels turning?...So with the older ratio and driving in a straight line, slightly larger tyres would be a benefit. However, when cornering, it would be advantageous to have the rear axel turning slower, so slightly larger on the rear is better on the later 1:1 ratio IRDs (as well as older ones)...
