found a good price for 20's but there the same witdh front and back, tire rack suggests a 245/30 in the front and a 265/30 in the rear.... will this be ok? considering the width is the same but wider tire in the back? they have a +35 offset, thank you for your time

 

Yeah, that sounds fine to me. You should get 35 series tires all around. You wont have any issues with rubbing, even if you slam it... especially since you only have 8.5 in the back.
