Tyre pressure on non standard size tyres

[Stew]

People change tyre sizes when they fit 19s, 20s or even different 18s. Often an unknown is the tyre pressure. The tyre make up has a lot to do with the pressure rather than the size so this is valid even for those running non OEM tyres in stock sizes.

 

What should it be?

 

Well, the best thing to do is start at 35 psi and then adjust the tyre pressures depending on how they feel. Make small adjustments (1-2 psi) accross the axle until you feel it's right. There is no correct answer as different people have different set ups for different conditions. It's all personal taste really!

most manufacturers provide a chart on their homepages where u can look for the right pressure.
