I have purchased a set of MRR HR2s and I have to say, I find them quite sexy. I have also purchased a set of Eibach Prokit springs for my 2006 G35 sedan. the rim sizes are 19x8.5(F) with a 35offset and 19x9.5(r) with a 45 or 48offset, I forgot which one, but as it goes for tires size, I'm still in question. I've used a tire calculator trying to figure out how close to the wheel diameter of the stock size to keep close to. I usually see most G owners with sedans stick with 245/35/19(f) and 275/30/19(r). I've seen some sedans where the rear tire was a 35series but looking closer it still looked a little big in the rear. It seems the 30series is not as big in some of the pics of those sedan owners who opted for 35series in the rear. Please, allow me some guidance on this matter. Oh yeah, I've gone thru quite a few of the forums looking for reviews, other's experience, or just about anything knowledgable, still no solid closure to what I seek. In short, should I go with 275/35/19(r), 275/30/19(r), or 265/35/19(r)? Any advice would be appreciated.
