Does anyone know why my 20 inch wheels on a 2010 x5 have 35 profile on the back and yet has 40 profile on the front?

Because the rears are wider, and hence to get the same rolling radius must be a lower profile.

Are the rear ones wider?

Rears are 315, fronts are 275s. The profile, i.e. tyre wall depth is the same, but the number is different because it's a percentage of the width.
