I am about to have my tires changed over at about 160 hours. I was alerted by Walt to the possibility that the tires installed by Cirrus combined with the installed camber was likely to produce a short tire life. The bottom line is that Cirrus specified a fairly low grade tire and installed the tires(at least on mine and Walt’s) at a higher camber than necessary (producing excessive wear). I cannot fault Cirrus, like any manufacturer, they are inclined to install cost effective components, I just wish I had had offered(and I am sure Walt would agree) the option to spend a few additional dollars on higher quality tires. For low number position holders, you may want to ask the question about upgrading the tires.
Additionally this aircraft is more difficult than most to learn how to land. As I have said in prior coorespondence it lands pretty flat and requires a lot less flare than a C-172 or PA-28. If excessive flare is applied, a hard (tire crunching) landing can result. It does not surprise me at all to hear that a SR20 trainer is experiencing pre-mature tire wear.
This is an excellent aircraft for recreational and training flight, but its unique (and in my opinion superior) characteristics take a little time to get used to. The likely scenario is that the SR20’s in club fleets will be relegated to the experienced pilots due to the cost of the airframe, but I must say that new or low hours pilots are likely to take to the aircrafts flight dynamics more quickly than higher hours pilots. This aircraft simply flies and handles better than the planes we were trained on, making the challenge of dealing with the inadequecies (sp?) of older airframes much less important and the transition to the SR20 a little more difficult.
I am waiting for some nice weather so I can get my bird back up in the air.
P.S. I am replacing my tires more as a preventative issue than due to actual visual wear. I land at Class B airports too much to risk the wear related blow out. Logan is pretty particular about not wanting to tow singles off of 4R or 4L on a busy afternoon (I could cost them thousands).
