I've searched the forum and there seems to be a lot of discussion about larger tires and what size tire will fit on a stock wheel,

but I did not come up with what the size tire that Jeep actually installed on an 1982 J10.

I do not have my J10 here to see what the door sticker reads.

I did go out and look at my 1986 Grand Wagoneer and the sticker reads 7.00R15.

Because my J10 and Waggie both 15" wheels and have 3:31 gears, I will assume that they both have the same tire size.

Okay, that sounds lame, but its the best thing I could come with.

My goal is the find the closest correct tire size for my J10 so the stock speedometer will produce the most accurate reading.

I know, I know...stock Jeep speedos are not accurate to begin with.

Without a detailed discussion, I have a real world need to have the most accurate stock speedometer possible.

I cannot afford to be caught speeding again.

Aftermarket speedometers are not in the budget and I would still have the issue of calibration.

I will need tires soon, so this where I am concentrating for now.

1. What is the OE Stock Tire Size that Jeep installed on a 1982 J10?

This J10 has an 8' bed is powered by a 360 V8, 727TF, NP219 and rolls on a Dana44 front axle and AMC23 rear axle, both with 3:31 gears.

2. Is 7.00R15 a correct size for an '82 J10?

3. Is there a link to a web site or download to a Tire Calculator that will calculate old school tire sizes to modern Metric tire sizes?

Yes, I have bookedmarked many tire calcs, like: http://www.miata.net/garage/tirecalc.html

But none of these style calcs work with old school sizes.

4. What is the modern Metric size for a 7.00R15 tire.

5. What modern 16" tire would good size that would produce the most accurate speedometer reading?
