Original tires size?

[Dunkin]

Howdy,

 

I am looking to replace all six tires on my 1947 - WHA48 two ton Dodge with new ones and I wanted to know if anyone thought that instead of installing 8.25x20 all the way around I might look at installing 7.25's on my steer axle.  I have my build out sheet which seems to show 8.25's all the way around, although it reads 7" below the tire size.

 

Thanks,

Roman

I show several versions of the WHA-48 from the factory Salesman's book shows two Tire sizes for the front both on 7 inch rims.  A 7.50 8 ply or a 8.25 10 ply.  Both on 7 inch rims.  It shows the same for the rears.  

 

If you see a code 130 13000 MGVW on your build sheet it came with 7.50 if you see a code 155 MGVW it came with 8.25.  both on 7 inch rims.

 

Unless you plan to run a lot of weight I would go with the 7.50 inch front steering would be easier.  It looks like the tire size and rear springs were the major differences.  Bob Harrison

Not the same year but, my B3GA has 7.50 up front and 8.25 on the rear and I agree, i think it steers a little easier without a load than my B3HH that has 8.25 all around.

i have no idea how the 7.50s would be.  my b1fa has 8.25x20s front and rear.  never really thought it steered hard, though.

Thanks Robert.  I looked at the record and it doesn't show neither of the codes you speak of unfortunately.

Howdy,

 

I have somewhat of an understanding how to measure the width of a wheel (without mounted tire) by measuring from where the bead of the tire goes from one side to the other.  My issue is that the wheels on my 2 ton Dodge don't conform to the same shape as wheels I am accustomed to.  I wanted to ensure that my wheels are 7".  I know 8.25x20 will work as they are on the truck all the way around, but I wanted to ensure that 7.5x20 would work on the drive wheels.  Is it safe to say that if 8.25's are on my drive wheels currently, 7.5 would work for sure?

 

Thanks,

   I have two 6 hole 20” wheels that I removed the old tires. I set the ring on one, and it measured 5”. There is a number on the face of the wheel, that may help. I don’t know if you have 5 or 6 hole wheels. Rick D.

Thanks Rick. I have a 5 bolt set up on my rig. Looking at the first first photo, it looks as though I could use a 7.5 on the front. The single vs. dual confuses me a bit though. I would hate for it not to work, so I think I am just gonna go with 8.25's all the way around as I know those are good on my rig.
