So getting closer to the 31.6" tire diameter is my main objective for a "corrected" rear gear. I may just stick with a 275/55-20 (31.9") and speedo calibrator to keep things looking proportioned. Nice pics by the way Zevox and BlackRam! You all are helping me decide on my choices as well.
Yeah that's one of my main reasons I want to run that tire. With the 3.55 gears and the 31" tire you get an effective ratio of 3.75. if I were to swap out the 3.55's with 4.10's, the effective ratio would be 4.34. I basically want to swap wheels/tires so I can improve the performance a bit. A little wider tire for some more traction and a smaller diameter to lower my gear ratio.
The other day in town I saw a 4th gen CC ram with a 3rd gen wheel/tire, the flower wheel with a 275/55. It was stock height. It looked about right. It looked like it was lowered an inch or so and the tires still filled the wheel wells ok. I think any lower would look funny. Your best bet may be the 275/55, it looked proportioned.
The more I look at Zevox's truck the more I am convinced that's what I want to do. Thanks a lot guys for the pics!
