going from 18s to 20s
I just purchased a set of 20's and been tryin to figure out that tire calculator for a while and cant come up with a right setup for tires
currently running stock
245/40 18 on 18.8.5 wheel
275/35 18 on 18.9.5 wheel
my 20's are 20b9 and 20x10
help me out with some tires combos so i get it right first time and not have to order new tires cuz the first one didnt fit right
BTW these are going on w210 E55 so not sure how much clearence there will be ..trying to get it as correct as possible to keep speedo in tact but also not run or bottom out .. THANKS IN ADVANCE !!!

Put in your stock tire size, and 20" tire size. Adjust until you get as close to 0% over all diameter difference.
