307-5a: Those rims should not be that hard to find , i do not think they are scarce just that there are more of the 14 inch. post an ad in your local area , rims wanted .
C-tymez: Good ideal. How and where does one post an ad?
307-5a: Do you know of any steel plain oem rims larger than 15 inch ? with the 5 by 4 3/4 bolt pattern ?
C-tymez: No sir, 15" is the biggest I've seen.
307-5a: If i go with the rally wheels i have , i was thinking about a tire size of 235 or 245 60 15 .A tire shop said for sure a 235 60 15 would fit and clear everything but they were not sure of a 245 60 15. I should look for an old worn out 245 60 15 tire, mount it on a rally rim , just to see how the size looks on the car and if it clears everything .
C-tymez: Either size would be nice.
Here's a way to figure the tire size in inches. 25.4 mm = 1"
Width is the first number of the tire.
Second number is the height, which is the percentage of the width.
235×60r15
Width: 235 mm ÷ 25.4 mm = 9.25"
Height: 60 = 60% × 9.25" = 5.55"
245×60r15
W: 245 mm × 25.4 mm = 9.65"
H: 9.65" × 60% = 5.79"
Not that big of differences. You get the ideal.
