Big Tires?
37X12.50X17 on Mickey Thompson Classic IIIs
The 36X12.50X17 Super Swamper TSLs on M/T Classic IIs that I need to find a new home for! They are a 8 X 6.5 lug pattern that fits a wide variety of trucks.
I have done countless hours of research for tires on big trucks, this is what I learned.
Generally: open shoulder tires (like the ones pictured above) will get poorer fuel mileage than closed shouldered tires. You will have shorter tire/tread life with an open pattern (like above) vs. a tighter tread pattern. That being said - I have a set of winter tires like the ones pictured above and they get GREAT traction in the snow!! They self clean and don't plug up like a Goodrich T/A tread will.
Skinny tires will give better traction in snow vs wide tires.
You DON'T want your tires to touch if they are dualled up. If you are close and put 1500lbs in your bed or hook onto a gooseneck that has a good bit of tongue weight, your tires will squat and touch. When they touch, they can not shed enough heat and you will blow a tire(s) quickly.
If you need to announce to the world that you have a small "package" and need to compensate by running big tires - single up your rear tires. Be aware that this will reduce your weight carrying capability.
Shallow tread, small grooves, closed shoulder = best fuel economy and worst non dry traction. The taller the sidewall - the poorer the fuel mileage. Tire sidewall flexing takes energy, and that energy comes from your fuel tank. A tall side wall has more flex than a low profile side wall.
Do the right thing and buy an extra set of rims. Run the "boring" tires on trips and commutes. Run the "fun" tires in the winter/mud season.
