Original OEM Tire Sizes on Early CJ5s

Correct Grant. Here’s a pic. Notice the raised “ribs” in between the bolt holes. These seem to be only present for the v6 models.

 

Correct. If you measure across the very Outside Diameter of a 16" wheel, it will be closer to 17", and a 15" will be closer to 16". The rim diameter is based on the diameter of the wheel where the tire actually mounts, which is down below that lip.

 

You just HAD to show me another pic of your awesome Turbines didn't you!!!

Would a 7.35-15 tire be around 29-30" in diameter? Not going to get these in particular but this offers a clue: Deestone D503 LT 7-15 105/101L D (8 Ply) AS A/S All Season Tire

 

Hi Grant.
Here are the 3 most common tire sizes run on our Jeeps, if keeping with the stock look.

They came with H78-15, which is approx. a 225 75R15 in metric. Around 28” tall.

The 7.35-15 is a smaller tire yet. Metric is a 205 70R15. Around 27” tall.

The tire size on my Tux are 235 75R15. Closest size to the vintage L78-15’s.
Around 29” tall.

I am wanting to go to a taller tire when mine wear out. With 4.88’s, not worried about any performance loss.
