Deal every day with our local tire dealer/repair center.
They handle all major brands.
A few things i've learned over the years;

Low tire pressure is more likely to cause a blowout then an over inflation do to heat.
If also handles worse. Wet or dry.
A narrow tire will go through snow better then a wide one.
Keep pressure no less then 5lb's(2-3 is better) under whats posted on sidewall for best wear, comfort, handling, and fuel milage.
All good 16" tires will have at least 44 psi max when cold on sidewalll.
Goodyear is over priced compared to most other brands all things equal(my own observation).

Just last month, drove my K1500 down to KY and back.
Cruise set @ 70 mph.
Tires have 44 max cold on sidewall.
Going there, pressure was @ 37 cold.
Before heading back, up'd them to 40 cold.
Got 2 miles per gallon better milage @ 40.
It was also about 10* colder outside.
And truck "seemed" to handle/ride better.
