Here is the comparison from stock to what i have now. So my sidewall is basically the same
Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
225/45-18 4.0in 13.0in 26.0in 81.6in 777 0.0%
245/40-18 3.9in 12.9in 25.7in 80.8in 784 -1.0%
and here is the link to it

If you already have a 7.5" rim with 42mm offset and are going to a 8" wide rim with 38mm offset it will leave the backside of the new rim where it is stock and put the outside lip .5" outward! We just wouldn't go with the racks recommendation of a 225 on a 8" wide rim! How about like Bart said and do 245 40's and add some Pedders to AO?
Another thing to ponder about the 235's on the new rims is they will clear everything but how about rubbing the fenders especially the rears when loaded?

ps; really sorry for my negative thoughts but I know that comes from being a true pessimist, (the glass is half empty theroy) .....
