Tire Size

Unknown

There have been a few discussions on the board as to which tire size to use on a Hudson. So I thought I would practice my picture posting and post what I saw on my Hudson.

I was taking progress pictures yesterday and I noticed that the junk tires on the front are the two different sizes I have been considering using. A 235/70/15 or a 225/75/15, according to a chart I have the diameter of these two tires should be the same but the 235/70/15 would be wider. What I found was the 225/75 was an inch longer in diameter, the tire pressure was the same. I like the wider look but may be much harder to steer.

Front view.

Passenger side with 235/70/15

Drivers Side 225/75/15


It is difficult to see the height difference between the two photos.

Since you have the different sized tires handy, if you feel like doing the extra "research", could you put the tires on the rear, and see if one size is more difficult to get off, using the "Hudson jack". I'm like you, I want the tallest, widest tire I can fit under mine, but it doesn't do you any good if you can't change the tire on the side of the road. I've heard of guys putting tires on the car while it was on a car hoist, only to have trouble getting the tire off when using the original jack-stand.

I am going with repro OEM tires from Kelsey/Goodyear. They still have the molds and are making them to be tubeless with modern materials.



So I have one order 7.10 x 15 at $140.00 each balanced and installed. I went with a 2 1/2 inch sidewall with a 1/2 reveal. They match the tubed Goodyear tires I just took off.

Wes:

I checked the rear tires and I have the same thing mounted there as in the front. A 235/70/15 on the passenger side and a 225/75/15 on the driver side. When I was working underneath the car and moving jack stands and ramps around I did not pay any attention as to which tire I put where. I have mounted all these tires with the Hudson Jack with out any more than the normal difficulty of mounting a Hudson tire.

I saw one coupe with 235/75/15 tires and they looked, to me, too large. They looked to over fill the fender opening. I think with the height of a 235/75/15 would really cause you to rachet the jack to the limit to get the back fender high enough. Up in the Modification sub forum is a black stepdown using 60 wide tires. Maybe he will respond as to the difficulty of changing this width of a tire.

If you think 75 series tires are tall, the original tires (78 series?) were even taller.

Divide the first number (235) by 25.4 to get the width of the tire at its widest point in inches. Multiply that by the aspect ratio (75(%)) to get the heighth of the sidewall. Multiply sidewall heighth by two, add the wheel diameter (15) and you have the diameter of the wheel/tire combo.

Pat & Wes,



If you were referring to my earlier post about the Black Beauty I purchased from Rudy Bennett; tires and wheels were already on the car when I bought it and fortunately I never had to change tires, therefore sorry I can't contribute to tire changing difficulties...Presently trying to determine what size tires I'll use on my '52 Hornet coupe, almost 100% confirmed on using 16" wheels, but haven't decided on tire size, however I liked the look of my wheels & tires on Black Beauty and probably will use same size.

If a train carrying the entire HET roster was travelling 60 mph from New York to Boston how many gallons of gasoline would the train need to complete the trip?

I gave up this stuff when I got my degree - now there's computer programs to do it!

(BTW - I know the question is bogus!)

Just kidding - this is always the thing I forget when contemplating tire sizes - thanks for adding it to the thread!

I believe the largest tire size for a stock rim is 235/75/15

This is what I am going to plant in the rear - I'll go skinny, same height up front for looks and steering.
