Cold tire pressure.

[Mungo]

Is there really such as thing as cold tire pressure when it's 90* outside first thing in the morning?

Just been thinking. If at say 50* my tire is suppose to be 40psi. Is it still suppose to be 40psi when it's 90*. If I'm not mistaken, it's all relative right?

have you tried nitrogen fills?

The psi ranges that the manual gives you are always for cold tires, they allow for a tire warming up and expanding. Even at 90 degrees and sitting overnight you have a cold tire, the heat that transfers through the tire after use, which greatly expands the molecules in the tire is what they are allowing for. I have heard some lower their psi 5 points in extrememly hot weather, this stays within the safe range, but none the less accounts for the heat....I keep both front and back at 35 psi for my dunlops no matter what the temp outside

Avon Venom Xs call for 40 in the front and 50 in the rear when cold. If I let my rear get down the in 30s I have an awful sway/wobble when powering through corners. As such, I keep my front at 38 and my back at 48 all the time (regardless of the air temp), which suits my style of riding.

As I mentioned above the front Avon on my bike calls for 40 cold and the rear calls for 50 cold.

As they say the devils in the details, and I tend to scan posts LOL

Yep, I keep my Avons set to 38 Front and 40 Rear which is a touch above the numbers for Dunlops on my bike. Like everybody else I check them cold before the bike has been moved no matter what the ambient air temp is. 8)
