Narrative:
On mar/sat/01, I performed an 'a' check on aircraft IAP. I signed for item 5A&B. The tire pressures on 8 main and the #10 tire was high. I neglected to deflate tire pressures. The practice I was accustomed to was that the tire pressures would drop into range when the temperatures dropped to normal. Since that time I have been informed of the correct procedure on tire deflation and the 5 psi difference of the other tires. I will comply with ert recommendation.
