NEED HELP WITH TIRE SIZES. WHAT TIRE SIZE CAN I PUT ON 15", 5-1/2" WIDE' 6 BOLT, ARTILERY WHEELS WITH STOCK SUSPENSION? I WOULD LIKE TO GO AS WIDE AND TALL AS I CAN WITHOUT ALTERING SUSPENSION. AND NOT HAVE PROBLEMS WITH TIE ROD ENDS, BRAKE LINES, ETC. THE MASTER PARTS BOOK SAYS 7.50 X 15" WERE USED AS AN OPTION WHAT SIZE AND BRAND NAME TIRE SHOULD I GO FOR. THIS TIRE THING CAN REALLY BE CONFUSING. I GOT THE OEM ARTILERY WHEELS AND WOULD LIKE TO USE THEM. ANY HELP WITH MY OPTIONS WOULD BE DEEPLY APRECIATED.
THANK'S
SAM

The 7.50X15 TRUCK tire is the largest diameter tire available in a 15" truck tire. It will give you 715 tire revs per mile. The 6.00X16 743 and 6.50X16 is 728.
NOt sure if that size is still available.

Are you sure on your maths? It seems strange that a 15" tire turns less revs per mile than a 16" tire. Admittedly I havent measured the roll out distance.

It is not my math, it is figures from the truck data book. The 15" is larger in diameter as it is of the 7.50 cross section size.

Those tires had an aspect ratio of approximately 80. So if you take 80% of the width to be the height and double it, then add that to the rim diameter the result should be the approximate diameter. That times 3,14159..... gives the circumference.
So the match would be:
7.50 x .80 = 6"
6.50 x .80 = 5.2"
6.00 x .80 = 4.8"
15+6+6 = 27"
16+5.2+5.2 = 26.4"
16+4.8+4.8 = 25.6"
Now you can multiply by pi to get the circumference or rolling distance for one revolution. Then divide by 12 to convert to feet. Finally divide that number into 5280 feet per mile to get the revolutions per mile.
It is far easier to use the numbers from Gene's data book as they use actual measurements and not the approximations from the tire size.
How Sweet the roar of a Chevy four!

Would you put a 750 tire on a rim with 5 1/2" width?
My 1951 1 Ton is now on the road! My 38 Master 4 Door is also now on the road .

Looking at the 1960 truck data book there is no 7.50X15 tire size listed. It was never a common trck tire size and probably is no longer available. You may be furtherahead using the 16"wheels and using a 6.50X16 truck type tire if a larger tire is desired.
f it were mine I would stay with the common 6.00X16 tire that 99% of the trucks used. Most years ad a standard passenger car tire but with is 6 ply rating for more load carring ability.

The 7.00X15 car tires were used on may large cars and fairly common.
