I looked and they are 265 50r20, they are wider than stock. My street traction increased dramatically. Stock height with those srt10 wheels and this size tire should have no problems at all with rubbing. Assuming you're still going for the street look, 265s in a 50 or 45 are your best bet.

You can see my same wheels with 45 series tires on a red Dakota in my profile by clicking my name, a guy left some pics in there. He has a 1.5" rear drop on it.

 

So that red one has 265/45's then. looks good which tires?

 

Yep 265 45r20s. I'm not sure what brand he went with, but the ones I have are Toyo Proxes II with 111V rating, load and speed. I like them a lot, they have been wearing very evenly, have tons of traction, and roll real quiet. The rain traction is really good and the snow traction was as good as any all season I've had in the past.

 

Which red truck are you talking about, read the post again, the tire size is not 265/45/20.
No sense wasting your time searching for the wrong tire size.

Just to clarify, I went with 265/50r20s on mine. The red Dakota in my profile is wearing 265/45r20s on the same wheels. Not sure what brand his tires are though.
