See chart below on pressure drop:
All reading are in Psi
Month. Date. Fr. Rr
Sept. 10th. 33 40
Sept. 15th. 33 40
Sept. 29th. 32 39
Oct. 13th. 30 37
Oct. 16th. 28 37
April. 3rd. 24 34
During winter storage between Oct 16th and April 3rd, there was a loss of 4 Psi which I consider kind of acceptable since 1 Psi per month is considered normal.
When I replaced the worn out tires I took a leap of faith and went for the conversion. It seemed to work fine.
Good information and good idea to check and record the pressure as you did. I've been surprised that my tubes don't seem to lose much over the cold months, maybe only 2psi...but then OR winters where I live don't get that cold, probably 35f night time average, and rarely below 30f. I just put new tires / tubes on. Thought about converting, but just didn't feel like doing it quite yet.
I'd be interested to see if there's any changes over 4-5 years.
