[FWDLK] TIRES and sizes and Jumbo Mudders

["Lars Larson 56 Plymouth" <LARSPAINTR@xxxxxxx>]

Ah here it is, nested in the buzzom of my Nov 52 Issue of Hop UP.
>From a cars and parts annual of maybe 12 years ago, a table of tire sizes...
to wit
a  pre 1965 7:10 x 15 tire has as its equivalent
8:25 x 15 1965 on bias ply
or
a G78-15
or in radials
205R15
or
GR78-15

Unfortunately no chart on proper rim widths for appropriate tire
which DOES affect safety  ride and handling
A 5.5 inch rim width for 56 Ply wagon or Fury should work up to that 205R15
Above that it may well be too narrow for the tire to have the proper profile
so the sidewalls work as designed.  Sure the tire goes round etc etc but it
screws up the handling- no matter how good we have convinced outselves these
relics handle.
Put the same tire on your 6 cyl plymouth with 4.5 inch rims and the tire dont
work
as designed.
If U have a 57 up >>>>>LOOK car Rim widths are greater due to change in tire
design and car weight/size.

I had to search the wreckig yards for a spare wheel for my 56 wagon with 11"
rear drums, and still got another bent wheel.
finally
My 51Merc 2 dr came with L 78 15 Radials.  Great on the interstate but not so
much in town.  Steering at low speeds was like for Arnold Schwartzenegger.
Replaced them with Sears bias plys of proper size and it was like Power
steering!!
