Whats ET stand for

 

Think its a saying for offset.

 

325/60-18 is the way those crazy metric guys measure 35x12.50's.

 

No, they're 33X13s.

First, convert mm to inches: 325/25.4= 12.79
Multiply by aspect ratio (x2): 12.79*1.2= 15.35
Finally, add rim diameter: 13.35+18=33.35

So the most accurate answer is 33.3x12.8-18 or rounded to 33x13.

 

Standard is so much easier.

 

We stuffed 325/65/18's on my buddies 04 250 with no leveling kit, only rubbed on the leafs/frame a little.

They're shorter, but they're wide.

For the inner plastic fender, zip ties are your friend, drill a few holes and pull it back and zip tie it in place. For the front valence, just trip the plastic a touch if it's hitting. I have a 2.5" leveling kit on mine with 35x12.5x17's and the only rubbing is slightly on the inner fender, but I'm missing most of the clips to hold it in place anyways so it's my fault haha.

 

I didn't even know that size exist... Great size for the excursion anf F-series. Nitto site says they are 32.99x12.83x18 fit rim sizes 9"-12" with 9.5" preffered. 3000 pound rating and come in load range D for a smoother ride.

 

The tires are 35 inches tall by 12.5 wide on 18" wheels the 8 refers to how many spokes r on the wheel 18" helo max 8 wheels

 

As Karl pointed out, a 325/60/18 is a 33" tire, not a 35". They're also a hair wider than 12.5".

 

A 325/65-18 would be a 35" tire (34.6 to be exact) because a 65 series will have a taller sidewall than a 60 series, all other things being equal. Did you possibly write the size incorrectly? Also, that 13 inch width is section width, not tread width. Therefore, the tread may be 12 wide.

Oh yeah, that 3rd line should have read "15.35+18=33.35" that 13.35 was a fat finger on my part.
