Inosine allows for wobble base pairing, which reduces the specificity required in the third position of the codon, allowing for fewer types of tRNAs to match different codons. Without inosine, there would be less wobble, which would require more specific matching between anticodons and codons, thus more types of tRNAs would be needed to match different codons.
