Default Tire size?

From all the reading I've done it seems like the 2500s sit higher stock than the 1/2 tons. Right now I have a 3/4 ton with a leveling kit and 3" body lift and I am taller than a 1/2 ton with an 8" lift. So my question is, what would be the max size tire I could put on without compromising the travel? Im running 285/65/18 atm and Im thinking about 325/70/18 b/c its the largest firestone destination m/t available. Im getting about 50k out of the set I have now and I dont really wanna mess with success. I don't have the money for toyos and nitto m/t isnt my thing. All flash and no real purpose if you ask me. Any ideas/suggestions?

Slightly OT, but the Nitto Trail Grappler isn't al flash like a Mud Grappler. It's more of an old school redesign that works REALLY well IMO.

That said my half ton has a leveling kit and Monroe load levelers. The load levelers gave it a rake....again, but I like the height. Anyhow.....I'm running 295/65/20s ( I read that the Nittos run tall so my overall height was 35.5) with no problems on factory wheels, so surely SURELY you could make the 325s work.

I agree. A 325 should work just fine. My only concern going to the wider section width and taller tire is whether or not you'd rub on the inside of the wheel well or at the trailing edge of the front bumper.

I suggest you go out and measure clearance between the tire and the fender (front and rear) and space between the tire and inner wheel well liner/suspension ball joint with the wheel pointing straight ahead. Then, turn the wheel to full steering lock and take the same measurements.

Then determine what the difference is in height between the 65 & 70 series tires to see if you still have room.

Lastly, determine the difference in section width between the 285's and a 325 to see if you have room for the additional width without having to change wheels or offsets.

I have a road armor bumper and it seems that I wont have a problem with turning. Now I'm just worried about the travel. I think I'm gonna go with the 325's. I have over 30k on my firestone destinations. I was hoping that they would die before then but I guess high mileage isnt a bad thing.

You should be able to clear those 325's and it will look great.

that is really helpful. somehow I figured a 325/70 ended up being ~34.9/12.7. This make a lot of difference. thanks for the posts guys

I really like nitto's and toyos. The pro comp tires are very nice especially the extreme a/t. General grapplers and cooper zeon ltz's aren't too bad either. Make sure you get the applicable d or e rating depending on how much you tow and stay away from passanger car load ratings intended for crossover suvs. I know i probably didn't narrow it down much since i offered so many choices but if it comes down to it go by price. All of them are great quality.

I'm sticking with E tires, I dont pull heavy often but I would rather not have another set of tires to pull a trailer.
