315/75 on 2nd Gen Dually

GermanCummins · 02-11-2008, 07:40 AM

Hello,
a friend ask my today, if i know somebody, who run´s 315/75 on the 6" wide dually rim?
He is looking on the Cooper STT!
I know that he need´s a 2" spacer, but is think the 6" wheel is to small??
On the Cooper homepage stay, that the tire need min. 8", but i saw some rig´s in this forum with 12,5" wirde tires, but i don´t know how wide the dually from those rigs are?

Best Regards Basti

I have 235's on mine Cooper STT they look kinda small to me. My buddy just put 285's on his dually and they look a little big for the rim. I think they would fit but may look funny on such a small rim. My dad has 315's Cooper STTs on his 2002 2500 Dodge wheels and they look fine. Not sure how wide non-dually wheels are though.

I think that the rims will be too narow I had 315's on my 02 2500 also and they are on 8" wheels also I would not run them on the 6" you would have to run really low air pressure so that they would not crown. Stick with the 285's!!
