Tire Pressure - Hot Climates

[Swanny297]

Hey all - I have read through all the posts and chalk test posts - gonna do the chalk test again next week.

I have my cold pressure at 32psi (285/75/17 Ridge Grapplers, almost 34”) - yesterday on the interstate ride felt a little rough and they had climbed to 38/39 (Louisiana 115F). Would it be OK to drop them 2/3 more PSI cold? Even cold it is still a little rough and chalk test was difficult because tires heat up pretty quick.

I have my 2dr Ruby/ BFG LT285x70Rx17 tires all set at 30PSI and the ride is smooth and steering is "right on"-today it was 98deg.
