I posted a question a few months ago about the Pro Comp Xtreme All terrains, but before I buy, just want to make sure I have everything right.

My question is, does the 325/65/18 = 35/13.5/18? Through my searching I have noticed that these two sizes have the same part number - PCT 58035.
But, when I do a tire conversion calculation, the 325/65/18's convert to a
35/12.5/18, which have a different part number.

So can you see my problem lol? I have 325/65/18's on my truck now, and would like to keep that size. But, most place online list either the 35/13.5/18 or the 35/12.5/18. So, which one should I order?

Really, I just want to make sure and double/triple check that after I order the tires online, they will fit onto my Helo Maxx rims with no problems!

 

Actually a 325/65-18 is really more like a 35x13.00-18 tire. I guess that is why some places are rounding the sizes down to the more commom 35x12.50 or up to a 35x13.50.

 

So if I order the 325/65 or the 35/13.5, which have the same part number, these should fit on my rims right? As, I do have Nitto 325/65's on right now. The 35/12.5's are a few hundred cheaper, would these also fit?

Thanx for the help!

 

Right, both will fit.

 

Perfect, thanx for the help. Now to order.
