just make sure that it comes in an LT or a 8 ply tire to stand the weight of a disco,
Especially for off road

Here are the specifics of the tire...

"Terra Grappler All Season / All Terrain Tires (201-180) by NittoŽ. 255/60R18, Speed Index 112 mph, Max Load 2469 lbs, Max Inflation Pressure 50 psi, Tire Weight 37 lbs, Overall Diameter 30".

Looks like it is a "light truck" or "SUV" tire, so I should be good. I am not planning on doing any rock crawling or mudding with it, so I should be ok in that aspect. I might drive through the pasture at the ranch, but that's about it.

BK, that is the info I was looking for (and the pics). Thanks!! I'm thinking of going to a 255/60-18 like this one... 255/60R18 Nitto Terra Grappler

It's a 30" tire, instead of the stock 29". Looks like it has some pretty good reviews too.
IIRC, those tires in the pic were Terra Grapplers. When I went to the 265/60 18's I had to flip the spare tire carrier to get the spare to fit, you may have to do that with the 255's.

Do you have any pictures of your 265/60-18's on the truck? I would think they would be pretty close to the 255's in size. Have you had any issues with the ride or stress on the drive shaft? How about your mileage/speedo being off?

Here's the pic, if my math is correct since the tire is 10mm wider, that would make the tire 12mm taller than a 255's (6mm x 2). But as far as speed accuracy, according to my GPS it's 1.5 mph slower at 60mph (at indicated 60mph I'm actually going 61.5) Since I'm going from a bigger tire to a smaller one I don't have a reference to what stock feels like, but it is easier for my old bones to get into the truck since it's about and inch and a half lower.

Perfect!! Thank you!

I like the way they look. I may look into the same size. Depends on price too. I found the 255/60-18's for $175. Now, I'm going to look and see what I can get the 265's for.

If you are worried about knowing what speed you are going just use a GPS. I run 265/65/18 on mine and I am off by 5 mph at 70. In town you will notice that your MPG will go down, but if you drive it on the freeway it will actually go up, not a lot but a little.

I notice the size more when I am towing my boat up a grade. It is slow at times.

The Nitto is a great tire, I have had several sets and was very happy with them.
