NO, thet are not just wider but taller, they will be 6" taller and that will make a very big jump in diameter and that will speed things up very quickly. I don't have the formula here to figure diameter or up to circumfrence but it will make probley 2' more travel for every reveloution. That would change the ground speed probably from about 10 MPH to as least 13 or 14MPH. The only tire size that had a wider version was the 12-13.6 that is the same height as a 15.5. The correct size for a B is 10" and if you take a 13" you are adding 3" to not only one side but both for a 6" increase in diameter. I had the 10-11.2" on me 46 B, 11-12.4" on my 49 B, 12-13.6" on my 51 A and the 13-14.9 on the big tractor a Moline U that put out 55 PTO HP. And changing to that much morr speed the brakes will be to small to stop the tractor at that speed and if they are indeed the 13 x 38 tire so old one will probably blow out and if at that high speed possibly cause the tractor to roll as it would be way too much drop too fast for you to control with steering. The 10 x 38 should have a diameter of 58" while the 13 x 38 will have a diameter of 64", do some math.
