Stock size is 245/75-16
If I go up a size to, let's say, 245/85-16s will I get better gas
I'm not looking for much, but if I have to change the tires why not
move up to a size that might help. I don't tow, I just carry tools and
sometimes some job site materials (concrete, gravel, etc).
I know that increasing the unsprung wheel weight will hurt MPG, so I
want to go taller not wider, I would love to buy lighter wheels, but I
think that would get too expensive. If you think otherwise please tell
me where to get cheap light wheels (still load D or E though).
Stock is 30.5 in
With 245/85-16s I'm running 32.4 in (6.3% increase and with toyo tires,
I gain 1 pound)
With 255/85-16s I'm running 33.1 (8.5% increase - limited tire choice).
I could also go with 17s (they are all over ebay), but I think I'll
gain more unsprung weight.
Of course I'm stuck with "highway" tires, but that's fine. This is a
work truck so I don't take it off road.
I know the saying, you bought a truck accept your MPG, I'm not crazy
about improving my mileage, but when I HAVE to replace a part I always
try and upgrade it as best as possible.
BTW: what highway tires do you recommend?
