Thinking about Staggered Wheels

Question from visitor, 07/02/2012 :I'm thinking about buying a staggered wheel set up for my BMW F10. Possibly 245/35 20 at the front and 275/30 at the rear. My question is, with this staggered set up, is it safe to have different tread patterns between the front and rear tyres ( but same tread patterns on the same axle) ?
Thanks.
