??? I'm using from a cold start 27 F 30 R

42 Front
40 Rear
when warmed up

I do this in order to not bend wheels...the ride is a bit bumpy but Its safer IMO.

I did what Cy did and still bent rims. If you have narrow sidewalled tires, they are going to bend regardless of the PSI.

Thought my 20's were running kinda flat,so I went to add some air last week and found that they were already at 40 psi. I wouldn't go any lower.
