Now here's a interesting fact (well I thought it interesting anyway). Alcoa Wheel Products is celebrating its 60th anniversary with "... year-long celebration of wheel innovation." I can't wait. Anyway it does have a lot to be proud of on the grounds that it's the world’s leading supplier of forged aluminium wheels and more vehicles are fitted with Alcoa forged aluminium wheels than any other brand. So there.
But why the shot of a 1948 American truck? Well Biglorryblog can reveal that Alcoa's first forged aluminum wheels appeared in 1948 and what better way to prove it than feature this black & white shot of a Mack tanker with Alcoa wheels...or is it a Peterbilt? What do BLB readers think?
And what a selection you have to choose from the introduction of Dura-Bright XBR, Dura-Flange, the WorkHorse wheel, the 22.5 x 17.00 Wide Base Wheel, and most recently the new 22.5 x 15.00 trailer wheel. Now click thorugh here for more
Voted one of the Most Sustainable Corporations at the World Economic Forum five years in a row (2004-2008), Alcoa says it's committed to reducing fuel consumption and thereby reducing carbon dioxide emissions. Errrr...that's it.

Has to be a Peterbilt,there is no dog.

It's a Pete, see the oval emblem at the top of the grill.

I haven't the faintest what type of tanker it is but they don't build them like that anymore that's for sure.
That is a Mack LTL.You can't see the dogs at this resolution but they are there.The last "L" stood for "light" as this model has the Alcoas and you can clearly see the aluminium front spring hangars.I own a LTL and a LTH.

Strange, but I'm sure that steering wheel is on the right hand side???!!! Don't think its due to parallax in this view.
