Cooper-I used the "vyta-flex 30" urethane rubber from "smooth-on"on my tires. I thought I was good by how easily they flexed but when mounted on the rim they became very hard. I think because it was a solid tire. This is your decision but I think the 60 may be a bit too hard. I agree with what you are thinking though. I would prefer the tire be to hard than to soft. If it is to soft it might just roll right off the rim on a side hill drive.
