There is a link to the Goodyear Farm tire handbook in the thread about posting a large document. I think KiotiJohn posted it, maybe IslandTractor. Good reading, may be useful.

Farmwithjunk,
I would take your tape measure to the dealer and measure a few tires of different brands. A big Ag tire dealer should have plenty to measure. This size difference is very common with tires. Start measuring truck tires, like 33's,35's, etc and you will be pretty surprised at the measurements, even as you say with the tire unloaded. In my experience I have found the Firestones tend to run larger in diameter than Goodyears for the same size tire. I would recommend checking out the Firestones and also if you drive by some tractor dealers, measure some tires. Just my 2 cents.
Good luck,
Russ

If you know anybody with a 1755 Oliver you might be in luck. Many came with the 7.5-15 according to an old "Official Guide" book.

From the Oliver board on ytmag: 29.2 on Firestone and 29.3 on Goodyear.

Sounds like I have the answer I was asking for. Thanks. They're not much different from the 6.50X16's that I have now. Found a set of "off-brand" 7.50X16's that are shorter than some I've measured. 3" taller than 6.00's. Might try that route. Gotta find a couple 6" or 7"X16, 6 lug wheels.

</font><font color="blue" class="small">( If your tractor is 4WD, be very careful to have the fronts and rears at the proper ratio, otherwise, the lead / lag of the rears to front will be off. This can lead to early tire wear, and linkage wear to possible linkage damage.
Read this article from Firestone to help you decide what is correct.

Thanks for putting up that link, I never realized about lead/lag and how to calculate it.

You're welcome. I first got onto it after reading that someone wanted to put larger tires on the front of his four wheel drive tractor. I knew that the ratios would be thrown off, but didn't know exactly how to tell him of the dangers. I found this link and thought it explained it very well, and probably saved the guy a lot of troubles.
