I would consider a 25% rise in pressure close to being a problem.
Pressure Pro has their upper pressure limit set at 24% but can be adjusted between 10-40 % by the user.
Have you ever been on the scales to see if the tires are within their load rating?
What I consider the most important is that all tires on an axle are running the same pressure within in 5 psi after a continuous run of at least 20 miles. This assumes they were at the same pressure when cold and not exposed to a heat source such as the sun.
Just remember the TPMS only transmits pressure about every 5 minutes when things are in normal ranges.
