What size and width are the wheels your looking at as that will make a difference to the offset and how the wheel will sit under the arches?
Generally et35 will be fine on a 18x8 or 8.5" rim, but as you go bigger diameter with similar width it's safer to go a slightly higher offset, for a ball park figure I'm running 19x9.5" all round with an et38 all round 235/35/19 tyres and that's about a limit I'd say as I don't get any rubbing issues. However if my wheels were anet35 I reckon they would just about catch, but on a narrower rim either offset will be fine.
