You have an interesting conundrum.
As already mentioned the 7.00x17 Tire will be shorter because it has a skinnier tube resulting in a shorter tire. Tubes don't really allow for different aspect ratios.
But I'd be more concerned about the odd tire. Mine came with 7.50x17 singles in the rear and 7.00x17 in the front, which I kind of liked. I eventually converted to tubeless (31" tall), but I think you should match tires across the axle where possible.
