My SE came with 18 inch rims. I am looking at changing out rims and tires in the very near future. What I have noticed around the forums is people seem to stick with the factory size or move up in rim diameter. These look great but the big rims, and tires to fit them, can be a little pricey. I am thinking about moving down in rim size. My plans were for a 17 inch rim and a tire with a similar diameter to what I have now (33) but wider. My PRG leveling kit should be installed shortly, allowing the wider tire which I think just fits with the lines of the Titan better. Going with a smaller rim and similar diamter tire will save me some cash and I shouldn't see any gear or speedometer issues. Since I don't see alot of people moving in the same direction I am wondering if I am missing something. Are there any other advantages to increasing the rim diameter that I have missed? Are there any disadvantages to moving down? Thanks for your help and input. By the way, I am not sensative so if you think my plans are retarded feel free to sound off.
