Your original numbers 235/30-19 F and 275/35-19 R give you 8.26% speed difference that will for sure destroy your drive train!!
yeah, you are right, I must have reversed the numbers as the other set-up is strange ( expected the higher ratio up front).
Dragonman , I hope you have 235/35's in front and 275/30's in back.......
