275/50/15 Nitto NT555R no tubs or rubs

Hi Gang, I had an email from a member requesting some info on my rear wheel/tire set-up and figured I'd post it for all the guys...and girls.
My Drivetrain consists of a 1999 Mopar Performance Magnum Crate unchanged with exception of an Edelbrock Air Gap intake and a Demon "Street Demon" 625cfm Carb and an Electronic distributor, still on the orange box, headers for now but going to Gils(Treblig) exhaust manifolds soon. Figure to be in the 320 horse range. A 727 with shift kit to a narrowed 8 3/4, 3.55 trutrac rear end riding on Mancini Racing xtra heavy duty springs hung on a MP offset spring kit. No wheel tubs but my rear quarter lips are rolled.
The car runs great, rides terrific and is fast enough for anything I can do on the street.
I haven't strip driven it yet but looking forward to it in the spring.

I'm running Wheel Vintiques, 15x8, 4 1/2" backspace, Mopar rally rims that I originally mounted 295/50/15 BF Goodrich Radial TA's on. The stance was awesome with these however I was having a bit of sidewall rub on the driver side only when cornering or over road bumps, even with the rolled lips, which just wasn't acceptable. I was looking for a tire with as much tread width as possible which gave me performance as well as clearance so I started looking at everything there is out there but still try to keep it reasonably priced.
I compared everything to the Goodrich radial TA as far as sizing and came up with the Nitto NT555R 275/50/15. The tread width was nearly the same but the section width from sidewall to sidewall was nearly an inch in difference and the Nitto's are V rated. The difference is in the sidewall bulge. The Nitto's have nearly a straight verticle sidewall enabling more clearance. They're super sticky and priced really reasonably. I def like them.

Here are the relevent spec comparisons:
BF Goodrich Radial TA 295/50/15
Dia=26.7", Section width=11.8", Tread width=10.4"
Nitto NT555R 275/50/15
Dia=25.7", Section width=11", Tread width= 10"


Here are some pics of my set.
