What psi is best for low profile tyres?

weezal, Jan 25, 12:22am
All I can see is max load 51 psi and I know its not that and I know its less than normal car tyre cos of the less area to fill with air. Suggesstions!

Red ones it's best to just give up now, too heavy

Doesnt matter how much area there is to fill. psi is a measure of pressure. Pounds per square inch. Doesnt matter if your filling a car tyre or a truck tyre. 36 psi is still 36 psi.

Im assuming you have a 235/35/18 or something like that. When i run 55 or 45 profile i use 38psi. When i had 35 profile i liked to use 40-42 psi.

No.

MORE pressure is required with lower profiles.

anywhere between 36 and 40psi will do just fine

Not much to add. but 38-40 is good. if you notice wear on the outside edges of your tyres, put in an extra couple of psi, if theres wear around the middle, drop it a few psi. if its wearing good, leave it alone :)

40 psi is good, run mine at that. 51 psi would be for carrying the maximum load allowed by the tyre (also on the outer wall).
