Hi I am new to this Discussion  I currently purchasing a 64 Deville convertible and It has bias ply tires that are 15 year old  they have L-78-15 tires and would like to put on radials . Question  what is a good cross to radial tire and is l-78-15 the original tire size. Thanks  Mark

The 235/75R15 is a good match.  Look into the Ironman tires for a white wall.

Hi Russ I am looking at the 235 75R15 in Ironman are those the RB12 after the tire size Thanks

[Mark Bartlett]

Hey Russ   what size white wall do you recommend and what was the stock width  Thanks

[3ft7bqmb7dryo]

I went with the ironmans, they ride well and feel good on the car. the width wall width is 1 inch. Not sure what the stock width is.

Original white wall width and distance from rim across the 3 tire suppliers is discussed in our Tires: Original Tires and Rims (Wheels) used on 1963 & 1964 Cad...   Scroll down and you will see  chart. Help Page.

Hi Russ looked at the Ironman Tires quite a few people are complaining the white wall turns brown  after a year have you had this issue

[Mark Bartlett]

Thank you Tony, So you agree with Russ Austin the 235 75 R15 ? Have you tried stick on weights for mag wheels?

I am surprised you don't run Bias Ply on your Eldo. I am strongly considering it for my 64 Fleetwood. By all accounts I have heard, the driving feel is better than radial. Bias Ply being softer. I am not a speed runner and most of the area around here is flat- so no large concerns there. The occasional jaunt on the freeway is the fastest I ever make it.

I recently changed out my Eldo's  bias ply tires for a set of radials, so I could drive the car and enjoy it a lot more.

I bought Coker's Firestone Steel Belted 721 LR78-15 "bias-look" radials with a very close to correct Cadillac 3/4" whitewall stripe. Matches the original spare in my car.  Overall diameter 28.78".

Price was $334.00 each. 

You can special-order tires similar to these from Diamondback (not sure Coker does this) with the sidewalls "blank", meaning there's no tire brand showing, only a size.  Makes the tires look classier to me.

Mark. I just purchased a set of 820-15 Radial Damond back tires with a one inch whitewall they look  very similar to the original tires  which where 820-15 bias ply with a one inch white wall. $304.00 each.  The original spare tire in the trunk was a 820-15 US Royal with a one inch white wall. I should have them in two weeks.
