WW2 Bargrip Tyre Shape?

[N.O.S.]

There are two types of bar tread tyres - the relatively flat tread one (e..g. Bedford Mk - Goodyear), and the profile with rounded shoulders (e.g. Omaha, as seen on post war Reo trucks etc.).

 

My question is - was the rounded profile used in WW2?

 

It never ceases to amaze me how little I know.

As far as I know, the rounded bar grips are a post-war pattern.

I agree with that Hanno. I think the square shoulder tyres were known as ND and the later rounded ones as NDCC. Wallace Wade used to show the difference in his tyre advert in MVPA Supply Line.

I am under the impression that the U.S. WWII had square edges to the bars and the British ones were rounded over on to the side walls.

 

I might be wrong though:sweat:

That's correct, NDT = Non-Directional Tread, a.k.a. NDMS, Non-Directional Mud and Snow. NDCC stands for Non-Directional Cross Country tread, a post-war pattern.

 

British wartime tyres came in the following types (source: Data Book of Wheeled Vehicles / Army Transport 1939-1945, edited by David Fletcher):

- Cross Country: heavily built tyres with bold, broad and deep treads.

- General Purpose: tyres of lighter construction than Cross Country, with narrower, shallower treads and more rounded shoulders.

- Sand: tread often similar to the normal commercial design, but it is broader and carcass is of special light constuction.

The best known British pattern is Dunlop's Trak Grip. As I understand it, this tread was moulded both on Cross Country and General Purpose tyres. The latter is shown in the pic below.

 

Hope this helps,

Hanno
