Can't exactly say what load rating is, but it appears to replace the
old "ply ratings," and relates to max PSI for the tire. The Cheng
Shin is rated at 70 max psi (8-ply rating), but filled to only 30 psi.
Gross weight is not the key number, but the weight on the nose,
though. In U.S. regs, the gear and tire must withstand 2.25 x the
static weight on the nose. www.chengshintires.com does spec actual
pounds, not for this tire, but same size in a tubeless nylon, 4-ply
rating is 330 lbs. (at 46 psi). Looks to me like the 8-ply rating is
okay, as at 30 psi if appropriate for the static weight, it can thus
take a whack of more than twice static - 70 psi. Even if this is
ignorant analysis, I note that Van's supplies same tire, but 6-ply
rating, for the RV-6A (read, holding up a Lycoming!).
Can you just slice and patch up the fairing to fit? That's what I did
with a junk bin fairing from Titan Aircraft, and thus came up with one
that's the smallest possible for this tire (actually fork size is the
limiter).
