Opinions on changing tire diameter for 230i xdrive

car has 225 40 18 which are 25.2 tall wanting to change to 245 35 18 which is 24.8 because the original tires are way to narrow they measure around 6.5 inches wide i want to put the 245 35 18 all around, will the shorter tire height affect the transmission or differentials in a negative way

That size is used on the rear with staggered tyres, so there shouldn’t be any issues at all. Having all the tyres the same diameter is beneficial to the xDrive system, so this would be a good swap. Just a slight possibility of rubbing with the front tyres, assuming 8.0 or 8.5” wide wheels used (stock 7.5” wheels are a bit narrow for 245/35-18 tyres), but the right offset can minimise that.
