325/60R20 on a 20x12 wheel?

Hey guys, I am pretty disappointed right now. I finally decided on a new set of wheels so I went to my local Discount Tire and was going to place the order. The wheels I want are the Moto Metal 962 in black/milled finish. I want to go with the 20x12 to get the deep dish look. I currently have 325/60 BFG AT/KO's (bought from Discount Tire) and they still have a lot of life left in them so I just want to get new wheels right now (money is tight also). However, they told me that they can't order the wheels because they won't install my tires on them. Now I know I've seen guys on this site and others that are running 12" wide wheels with 12.5" wide tires. My tire (metric) measures out to just over 12.5" so I don't see what the problem would be.

So my question is, can I run my current 325/60 BFG AT's on a 20x12 wheel? Thanks for any help!

Most tire shops will only install tires on wheels that meet the specs of the tire manufacturers. It's generally out of concern for legal liability, not to mention, drivability and longevity.

What does BFG show as the "Approved Rim Width" for your tire? Intuitively a 20x12 wheel seems too wide for a 325/60/20 tire. On the other end of the spectrum too narrow of a rim can also cause problems.

I agree and think that tire is better suited to a 20x10 inch rim anyway.

Got questions about your 6.0?

Hey, thanks so much for the advice. I didn't even think about seeing what BFG recommends for the tire. I just looked it up on their website and BFG recommends a rim size between 9-12".

So I just got off the phone with Discount Tire and they are going to call BFG and verify it. They said if BFG says it's okay, then they can do it. I'd like to stick with Discount Tire because they've always treated me right on numerous other tire deals, and since I bought the tires from them they will install them on my wheels for free. I'll keep you guys updated on what they say. Thanks again for the advice! I love the good knowledge on this site!!!

On an interesting side note, the Toyo Open Country M/T they tried to sell me that would "work" on the 20x12 rims I want were the 37x13.50x20 tires. So for kicks I looked them up to see what size rim Toyo recommends for those tires. Low and behold, Toyo recommends a rim size between 8.5-11". So according to Discount Tire they will work, but according to Toyo, they won't. I know the Toyo's will work on a 12" wide rim because there are literally thousands of people running that tire on a 12" wide rim. Anyways, just thought I would point that out as well.

I just looked it up too, because I was sure you misread something. I am blown away BFG recommends a 9-12" wheel for a 12.5" wide tire!!!

I remember seeing Nitto say 8.5-11" wide 9.5 nominal for a 35x12.5.

Yep, I thought I was seeing it wrong too, but it's plain as day on their website specs for the tire.
