I am in the same predicament, maybe not so bad perhaps since I am using 5.00 x 5 McCrearys that fit in my wheel wells. However, these are old and have just come to the end of their useful life and like you I have found significant dimensional differences between the original and the current Desser/Airhawk 5.00 x 5. So I have been looking at the Lamb 11x4 5 8 ply which is small and should not cause any interference problems. The problem with this tire is that it only seems to be rated for 500 pound static load. This is based on the only specs I could find for this type of tire which was specified by Desser for the Aero Classic. I don't feel comfortable installing these since my plane is almost always at gross on takeoff. So I am looking for 5.00x5s (rated for 800#) to replace my original McCrearys. Wish the manufactures would publish accurate inflated dimensions!
In the meantime, I am grounded until I solve this vexing problem. I will keep you posted offline as I learn more
Thanks

Folks,
The recent correspondence on old LNC2 tires prompted me to replace my 1990
vintage originals with new tired from ACS, sold as “Lamb” but labeled “Cheng
Shin.” Unfortunately these are slightly larger diameter—the profile is
rounder—and the clearance from the closeout rib is reduced to about 50 thou with
the wheels fully up and 40 psi pressure in the tire. It’s close to the
hydraulic cylinder pivot bolt also, but that could be fixed by replacing the hex
head bolt with a countersunk structural machine screw.
Can anyone offer guidelines on minimum clearance here? I’m concerned
that with use the tires could become more flexible and possibly jam in the up
position. Does anyone have a diameter comparison between Cheng Shin and
the Desser(?) or other alternatives and suggest a supplier of smaller
tires?
Thanks in advance.
Chris.
