White Wall Tires

Thursday, February 11th, 2010

Prior to the 1960′s, trucks were used as work vehicles. On Friday nights, most were parked for the weekend and the family sedan was the transportation vehicle.

It was a conservative era when you bought only basic necessities. A $5.00 grocery purchase was more than most could carry. Finding white wall tires on a truck would have been a rare sight, indeed. Very few cars, except for most luxurious models, would have had white walls even as an option. It should be remembered, that most roads, except highways and those in the main part of town were gravel, dirt, or sprayed annually with tar.

Of course, a dealer would have been happy to install aftermarket white wall tires, if the customer made a specific request. For a price, the dealer would provide any option to keep a satisfied customer and make a few dollars.

On GM trucks, white walls became a factory option in mid-1955, partially because of the introduction of the Chevrolet Cameo and GMC Suburban carrier and also due to more roads becoming paved. These very deluxe pickups, as well as several of the other well appointed 1/2 tons justified a white wall tire for those wanting it all!

Almost none of these deluxe models would have been given their second set of white wall tires. By then, the pickup was older and being used more as a hauler, not for appearance.

Wheel Striping

Thursday, February 11th, 2010

During the 1940′s through 1950′s placing pin stripes on automobile wheels occurred on most all brands. It was an inexpensive touch that added a little flair to the appearance of a new wheel. The stripe could be added quickly with a machine on a rotating wheel. The factory didn’t need a human as on the body stripes.

GM was no exception. They had been striping most new car wheels for almost 10 years. Beginning with the 1947 Advance Design trucks, this striping even was used on ½ tons that had the deluxe package (not the standard models). This extra was continued through the 1947-1955 body style.

The attached photo shows a used original never repainted 16″ 1/2 ton deluxe wheel. Note how perfect the 3/4″ stripes are applied. With the addition of the small chrome hub cap, the wheel drew attention

Artillery Wheels

Thursday, February 11th, 2010

The term artillery wheel is a nickname adapted from a scalloped type wheel often seen on US military vehicles in World War I. The similar appearance at a distance to GM’s scalloped steel wheels quickly gave them the name artillery.

On GM trucks, this style was first used during 1934-36 as a stock six bolt 1/2 ton 17 inch wheel. It was much stronger than the existing wire style wheels due to it being less susceptible to bending when hitting a large pot hole or sliding against a curb.

Though this 17 inch unit was discontinued on 1/2 tons for 1937, a redesigned 15 inch artillery began as GM’s stock wheel on that year’s 3/4 ton truck. It was stronger and wider but was still a non-split rim design. This remained the GM 3/4 ton wheel through 1945. By 1946, six bolt wheels on trucks were limited to 1/2 tons. The 3/4 ton would now have 15 inch 8 bolt split rims which remained stock into the 1960′s.

Today, we sometimes see 1947-59 GM 1/2 tons equipped with these early 15 inch artillery 3/4 ton wheels even though they were not placed on factory trucks after 1945. To many, they provide a unique appearance on the later 1/2 tons and will still hold the trucks current hub cap.

After Market Wheels for Older GM Trucks

Thursday, February 11th, 2010

From 1934 to 1959 GM 1/2 tons came from the factory with a tie rod assembly that extended side to side to almost touch the front wheels. With everything stock, the tie rod sits about 3/4 inch from the inside of both original six hole wheels and all fits just right.

A problem exists when someone attempts to add a more modern wheel. For example, the mid 60′s and newer 4×4 wheels have this 6 hole bolt pattern but their width causes them to contact the end of original long tie rod. Changing from the approximate 4-1/2 inch original to at least a 6 inch width just won’t work.

Solutions for adding a more sporty wheel are very limited with the original suspension. One almost unknown method is to replace the original GM multi-piece tie rod ends with the more modern knuckle ends introduced in the 1960′s. There are currently available and are 3/8 inch shorter on the outer end giving that much extra room for a slightly wider wheel. (It is not recommended that flat washers be placed over the stud between the wheel and drum as this can cause breakage.)

This GM six bolt pattern is also shared with several Japanese pickups. Some very attractive more narrow aftermarket wheels have been produced for their imports in past years.

1954 First Chevrolet Truck Wheel Cover

1954 wheel cover 1

It’s 1954 and the Korean War is now history. The wholesale price of non-ferrous metal such as chrome, stainless steel, nickel and copper are dropping. American have more disposable income and are beginning to ask for deluxe accessories on their trucks instead of just for the family sedan.

Of the many accessories introduced in 1954, the full wheel cover was a first for any Chevrolet pickup. These stainless steel covers were not borrowed from Chevrolet cars. They were exclusive for the 1/2 ton pickup 16′ wheel. These were Chevrolet dealer installed accessories and not added on the assembly line.

Today, locating a restorable set of these unusual accessories is very difficult. Many sets that were left over in dealer stock probably found their way to the used car lot to dress up a trade in.

Note: Don’t confuse these covers with the 1947-48 Chevrolet car, deluxe 16′ wheel covers. They have red centers and a different stamping in this area.

Hub Caps-Used 15 Years

Thursday, February 11th, 2010

Many of the tech articles on this web site emphasis’s the subtle ways that truck parts were made economically by GM. Truck often received Chevrolet car items that were used the year before. Sometimes even other GM brands sent their older items to be placed on assembly line trucks.

Of all the ways GM saved money on truck parts, none is more unique than the savings on 1/2 ton hub caps. Chevrolet pickups used the same baby moon style hub cap from 1940 through 1955. The skins and basis are the same. A relative inexpensive addition was simply changing the lettering or emblems on the outer brass skin. They required a change in tooling, not expensive for a company the size of the Chevrolet Motor Division. The stamping department just kept making the same base and skins. The skin surface stamping changed as was required by the design department each year.

Check the following pictures. The base hub caps are all the same. Some of the car hub caps are the same as the trucks. Even GMC trucks decided to use these caps between 1947-55. After all, just placing the three GMC letters on the skin added much savings to the company’s bottom line.
