Just wondering why you wouldn't use 18s-20s rated for 4060 compared to 4500 rated 19.5s. If you think the wheels are able to survive higher than the rating, it seems the 18s-20s would be good enough. Of course, then there is the air pressure to reach 4500. I'm not sure everyone always runs high enough pressure to actually be rated for 4500.
