There have been some questions about tires and batteries recently.  Specifically regarding tires, the Cheng Shin tire for the 320.

 

I have been using that tire from day one on my 320 (December, 1994) and have been very satisfied with its performance.  I put on new tires in January this year after two and one half years and about 235 flight hours.  The only problems I have had were brought on by by underinflation, causing flexing and a pin-hole leak in the tube side wall.  I keep tire pressure at 48 psi (+/-) and have had no further problems.

 

I replaced my battery last month (November) after seven years on the old one, a Concorde RG-35A.  In the colder weather it was starting to struggle a bit cranking the engine and I didn't want to get stuck somewhere.  The new battery is a Concorde RG-35 AXC and it really spins over the engine on start.  During long periods of sitting in the hangar I keep a trickle charger on the battery.  The leads are attached to posts I installed in the right hand wheel well cockpit closeout rib.  That battery tending has significantly increased battery life.

 

Regarding tire life, I should note that I do not do touch and go landings, I do no training with my airplane.  I use the airplane to go places only, and it do go places in a hurry.  I don't jump on the brakes after landing either, using aerodynamic braking and letting it rollout.
