Letís define those categories.
1) Under-inflated: Any pressure below the recommended chart pressure.
2) Just Right: Any pressure above the recommended chart pressure that does not exceed chart pressure plus 20%. Preferably between 10-20% above the recommended chart pressure.
3) Overinflated: Any pressure that exceeds chart pressure by 20% or more.
The 10-20% recommendation offers us a Just Right range of 10%. Ten percent of 80 is 8, 10% of 100 is 10. For many of us, we therefore have an 8-10 psi range within which to keep our tires properly inflated. This should not be a difficult challenge. Accomplishing this should not occupy a great deal of our time.
Keep in mind that we round up in 5psi increments on the chart as well. So, we could be as much as 4psi over just by rounding up. That is, if we were to build a chart in 1lb increments. Thatís 4-5%, then add another 25%, from say 80 to 100. Now weíre pushing 30%.
Itís just too easy to keep it between 10-20%. So why knowingly go just a little over? Makes no sense.
