Can anyone tell me the rolling radius difference between a 31x10.5 r15 and a 265/70 r16 which are the factory size, been offered the 31s on rims brand new for cheap and wondering the radius difference, cheers

31"x10.5 r15 diameter 31" x 25.4mm = 787.4mm diameter
265mm divide by 100 =2.65mm 2.65mm x 70mm (sidewall size) x 2=371mm + (16" x 25.4mm = 406.4)= 777.4mm
so the 265/70/16 has a slightly smaller diameter.
