Will this fit a 05 rcsb? Tire size suggestions?

 

It will fit yes. What is your suspension set up?

Stock height you could probably fit a 285/70 on that wheel if thats the look you are going for. If you are lower I would go 275/60 nitto 420s

 

Its at stock height now. Thinking of doing the djm 4/6 kit.

 

then I would do the nitto tires. They are a tad shorter than stock with a slightly wider footprint. They will look good and should provide decent grip/

 

If you're going the drop route, I'm quite happy with my General Grabber UHPs in 275/55R17. Much better handling than the Nitto 420s and superior traction as well (the 420s is too slippery in the rain for my liking).

The downside of the Grabber is the directional tread (which gives the traction boost), which prevents rotating the tires from one side to the other.
