46% of 257 = 46% * 257 = 0.46 * 257 = 118.22
You can, of course, but it is not a recommended substitute. It is never acceptable to go over or under 3% of the OEM size. The 235/75-15 is 4.09% larger in overall diameter than the OEM tire. You can however switch to a 235/70-15 which is an almost perfect swap at only 0.92% larger. This would be the size you need to go to.
40% of 257 = 102.8= 40% * 257= 40%/100% * 257=1028/10= 102.8
257 - 35% = 257 x (1 - (35/100)) = 257 x 0.65 = 167.05
