I have a 1997 Thunderbird with a TVS2300-blown big bore 2V modular. The combo makes 560 RWHP and 520 RWTQ. Rear tire size is limited to 285 width by the wheel wells, and I'm running a 285/40-18 on a 10" wide rim. Originally tried Nitto NT555 G2s all around on the street, but traction was nonexistent. After switching to NT555Rs on the back, the car was much more manageable. The tread depth is down substantially after about 6,000 miles, so I'm looking to replace them. My question is whether to just get another set of NT555Rs, or switch to the newer NT555R2. On paper, the newer tire looks more desirable, but I'm concerned about the lower load index (96 versus 101 for the R). My car weighs about 3900#, and when we road trip it with luggage, tools and two aboard it maxes out between 4400 and 4500#. Would the 96 load index be sufficient? Also, what experiences have people had with the NT555R2, good or bad?
