Hey, this is my first post in this forum, sorry if I'm a little wrong in mower terms... I've been working with my Dad for a while now, and as long as I can remember, he's always had flat tires on the fronts of his mowers(not on purpose, though). I know flats on the larger rear drive wheels are a big no-no. I think it's do-able with the 36" ExMark Metro because it's fairly light, especially in the front, but I'm not sure if it's good with a 42" Wright Centar. I couldn't really find anything about it on the internet, other than people complaining of flats and $100 flat free tires, but I was just wondering if there was any actual disadvantage and/or danger to having flats up front. Any responses are appreciated, and thanks in advance.
