I'm switching from 14 to 15's and was wondering if I need to run a different tyre pressure than spec'd for the 14's ?

I have a 1988 90Q and it recommends (I think) 34/34 unloaded, and 34/42 loaded. Should I just run the new tyres at the same pressure ?

Also, I've started Auto-Xing, and I've seen a lot of recommendations to up the tyre pressure, but my old tyres were rated to a max pressure of only 35psi. Can you go above the max pressure if you're at a lower than max weight ?

THanks

I woudl base off of 14" OEM size pressures & add +1 psi to that.
