I am crazy about tire pressures and I know how soft the KM'2s are. If you want them to last the pressure needs to be even between them. My JKUR with 35x12.5-17 with stock bumpers rides between 28-30PSI cold. If it gets hot out I let out some air to keep them consistant. I did the chalk test to determine pressure. 35 PSI cold might be too much air for that tread. The center of the tire will wear quickly, and the ride will be rough.
