No, the tithe is not part of the law. It was before the law and our share of covenant with God. Besides, God said if you tithe he blesses so it's a good deal anyway. Jesus said, Render unto God what is God's, We are bought and paid for with a price and we have things That do belong to God. Besides, Jesus still receives tithes, so if the tithing door is open, it's a good opportunity to keep blessed. Whatever the case, folks can keep their money if they like and not honor God for the abundance of all things. There is no law saying we have to tithe, but it is part of what Abraham did and we are blessed with faithful Abraham.
