Tire psi in 100+ degree weather??

The spiders would have a easier time with mismatched tires on opposite wheel ends on the same axle than the power divider would having different heights on the front and rear axles. As far as matching tread depth I would say no more than 2/32nd. Tire shops say 4/32 but I think 1/8th of an inch is just too much difference.
