Technical Rear tire size help?

Anyone know what size tire is in rear of this car .
I know the front one is a Firestone 500-5.25/16.
Or what’s a good rear tire for a 32 coupe with fenders ? 650-670-700?

 

What goes around comes around,,,, When I was a young hotrodder everyone wanted 14 or 15 inch tires...Old Chevys were the worst because they were 6 lug...They use to search hard for the 6 lug 15 inch Chevy rim...Now my new pickup has 18 inch back to 1932 I guess...

 

Can't go wrong with a 700 or 750 16 in the rear.

 

X2 what @Dan Hay said ^^^

 

the taller the tire the less RPMs the engine has to put out at the same speed...
what are the travel plans... long trips or round town...

 

I have a set of Firestone 550-16 fronts and 750 rears
Was going to run no fenders but decided to keep them on for now . The 750 -16 looks huge .
Plan on driving it a lot lot short trips . Some freeway driving. .

 

Is there a big difference between a 750-16 vs 700-16?

 

Check Coker's website and go to Firestone tires and they will have the specs for the various sizes.

 

It depends on how much room you have for the tire. A lot of people shoot for a 7.50 rear tire. BTW those are 16" wheels in the picture (by the distance of the flat area between hubcap and wheel hoop).

 

On Cokers site a 7.50 16 pie crust is 31 inches OD
700 is 30.4
670 is 28.62

 

I tried calling Coker ,guy on the phone didnt know to much .

That's page 3 of three pages of bias blackwalls.

 

Here is a closer up of the rear tire sidewall...8.00 to 8.25 - 16?

 

The gap between the edge of the tire and the edge of the fender...........both horizontally and vertically will detrmine a whole lot in wheter your car "looks right". Everyone......not really, but many 32 builders feel this is only right when the gap is reasonably small with a large tire. Here is a picture of a 265/75/15r tire and its fender relation. The tire chart says its 30.6" in diameter and 10.4" wide. If that suits you, you can use the attached chart and look for a similar size in 16" tires.

More importantly what’s the transmission and rear gear you have?

 

39 trans with a 39 rear end . not sure on gears

 

tiresize.com is a good resource. I like the way you can search in 1" overall-diameter ranges.

For those who are interested, the way to decipher metric tyre sizes, taking that example:
(265 x 0.75 x 2)/25.4 + 15 = 30.65" nominal diameter
265/25.4 = 10.43" nominal section width

Actual tyres are the size they are. The designations are rounded to the nearest 5mm width and 5% aspect ratio.

 

Here is a pretty cool link, it will tell you actual tire height based on tire size, so
you can measure how tall a tire would be for your car. It has worked well for
me in the past...

I run 7:50 x16 in the rear on everything and front depending on fenders and era of car. I have a set of 8:20x16 but are too tall

 

What do you have on fronts ?
Rim width on back 4-1/2?

 

Yes rim width in rear is 4.5 and run 5:50 highboy and 6:00 on a fender car . I also try to run 4.0 rims in the front with the 5:50 if I can find them. The 4.5 rims is ok with the 6:00 and unnoticeable on what your width is.

 

This has 5.25 on front . You think this is 750 on back?
