8" wide rim is really the best width with a +45mm offset, you can get away with +40mm with a 8" wide rim. Anything between +40 to +45mm offset is what you want. Anything smaller then +40mm you need a 7 to 7.5" rim or you will have rubbing issues. You have a 8" wide rim with a +35mm offset you might get away with a 225, but thats a narrow tire for the rim size. A 235 may even still have a rub issue.
