I bought two of these desser tires for my Lancair 320. =20= They=20 look
terrific, but I was surprised to see that they had stamped on the=20 side
"max speed 62 MPH". They also had "Tubeless" stamped on the=20 side. I
called Desser to inquire, and they assured me these tires= are=20 the same
as their previous offering for our airplanes, only slightly be= tter=20 built
(and they look a lot nicer). Their previous tires wer= e=20 also only
tested to 62 MPH, it's just that they were never stamped with= =20 that
information. These new tires have the stamp, but desser sale= s=20 rep
mentioned that in future lots, they will remove the "Max speed 62=20 mph"
stamp.
