I would consider a 25% rise in pressure close to being a problem........
I agree with this.
If I compensate for the change in ambient temperature - which should result in a 4 psi increase - then the actual pressure buildup is 8 psi - 15%. That is too much!
I think OP needs to use a tire with more load carrying capacity - more inflation pressure (if the tires are rated for such), a higher load range (with an increase in inflation pressure), a larger tire
- OR -
he needs to slow down.
Best guess is that the tires are ST tires and are rated for 65 mph.
