It turns out there is a wheel wholesaler warehouse here in fargo that
has some of the ford rims in stock.
I went over there friday with a tape measure and got some dimensions.
I also remeasured my stock '53 rims this weekend and also a '63 lark
stock rim I have around. So here for future reference is what I
found....
Stock '53 rim:
Tire bead inside Width: 5"
Overall outside width: 6-1/8"
Backspacing: 4-3/8"
Offset (tire centerline to inside edge): 1-5/16"
Center hole ID: 2-3/4"
Stock '63 lark rim:
Tire bead inside width: 4-1/2"
Overall outside width: 5-5/8"
Backspacing: 3-5/8"
Offset (tire centerline to inside edge): 1-1/16"
Center hole ID: forgot to measure
6" Ford rim, NWRA X-40273:
Tire bead inside width: 6"
Overall outside width: 7-1/8"
Backspacing: 4-1/8"
Offset (tire centerline to inside edge): 9/16"
Center hole ID: 2-3/4"
Currently, my '53 has a stock mid 70's Maverick 8" rear end in it.
With the stock '53 rims, my track width from center to center of the
rear tires is about 54-1/2" to 54-3/4". I have 205/75R15 tires on it
and there is about 3" to 3-1/2" clearance from the tire sidewall to
the fender lip on each side.
While at the zone meet in WI last month, I took the opportunity to
check out some other cars. There was a '54 Champion hardtop there
with stock sized bias tires (6.70-15). I'll assume it had the stock
wheels since everything else about it was stock.... Track width was
56-1/4" center to center and about 2 to 2-1/2" clearance from the
sidewalls to the fender lips. I also checked the rear track on a '58
packard hawk and it was also 56-1/4".
Soooo. It would appear that the Maverick rear end is about 1-1/2" to
1-3/4" inches narrower than the original rear was in my car. Taking
into account the rim width increase and change in offset, if I put
these wider rims on the back, I should increase my track width about
1-1/2" and get back what was lost. The outside of the wheel should
push out 1-1/4" over what I have now and will make my fender clearance
essentially the same as the stock setup was like I measured on that
'54.
