Wheel interchange
 

I was visiting with another a owner on wheel interchange. The discussion was would a wheel from a 28-29 fit on a 30-31? I said it should with the exception of the hub caps. Who is right?

They are all interchangeable other than the caps

They interchange except the caps assuming they are not the AR (early '28) wheels.

You can also use 1935 Ford 16" wheels or 16" Kelsey-Hays wheels. Later Ford wheels have the same bolt pattern but need a spacer to prevent wheel cracking.

add to all the useful info above .. When I measured them a few years back the fitted 4.50x21 had a rolling perimeter of 2450mms and the fitted 4.75-5.00 x19 had a perimeter of 2300mms... So you may fine the gearing slightly different .. ( I'll let you convert millimetres into feet and inches:) )

I ran 18"s on my A 50 years ago.

Re: Wheel interchange
 

I've used 15 inch wheels on one of my model A's with no problem except it looks more like a hot rod . I also like hot rods and figure if it suits me it is OK .

Damnit, I didn't know there was going to be a math problem to solve!

Re: Wheel interchange
 

When I put 19" wheel on the back of my '28, he hubs push the hub caps off and I can't see what is causing the hub/axle to protrude further than it would on a 30-31

Just to complicate your mathematical exercises for the day. A Firestone tyre will have a slightly different rolling perimeter than a Goodyear tyre.

16" Ford or Kelsey Hayes wires and modern radials.Better ride,better braking,better handling.
Could never understand the 'looks' argument,the car is safer to drive and a better ride with modern tire sidewall flex and more tread contact..

I believe this is also a reason why the car endured,removing the 21's or 19's on a worn used car and fitting 16's changed how it rode and felt,they were less apt to sell or scrap it.

Re: Wheel interchange
 

If you are THAT concerned about safety you should be putting the front fenders back on your car as it would be much safer should you get caught in a rain storm rather than removing them for "looks".

Re: Wheel interchange
 

dont rain much here...but thanks for your concern.

Re: Wheel interchange
 

I believe it was more that it was easier to get 16" tires during the war than 19" and 21" than it was for comfort. That is why a lot of Model A wheels were reduced in size. I just seen a set of 16" "Model A" wheels the other day.

Re: Wheel interchange
 

Ruth, you are absolutely right! During WII, 19's and 21's were not available.

Re: Wheel interchange
 

26-27 Model T wire wheels LOOK like the 28-29 Model A wheels - but the bolt circle is different and won't fit.

I didn’t know that. How come the 19’s and 21’s were not available, but 16’s were available?

Shortage of rubber, all rubber went for war effort. Not too many Jeeps and trucks with 4.75X21 tires.

They rationed gasoline not because we didn't have gas, it was to cut down on people driving and using up their tires. Most all latex came from Asia with some coming from Brazil.

Plenty of good books with interesting facts about the WWII. IMO, none of the good stuff was taught in school.
