For maximum tyre width I'd recommend 165/60s.
Here are some estimates (from a C program if you want it)
Specification Sidewall Radius Rim/Tyre Circumference Revs/Mile Difference
145/70-12x4.5 102mm 254mm 78.8% 1595mm 1009 0.0%
165/60-12x4.5 99mm 251mm 69.3% 1580mm 1019 -1.0%
165/65-12x4.5 107mm 260mm 69.3% 1631mm 986 2.3%
Whether they fit in the wheel well is your problem.
