Tires and wheel sizes...ughh...some questions

[94gt]

So, I think I am going to try the Vors D38 for my back wheels as they have a 19x11 that looks really close to the PP1 wheels. Since I have added the Roush Phase 2, these P Zeros just make it unable to hook up at WOT. My original though was to go with the D38, with a Proxe R888R, in 325/30/19, I know 11 isn't optimal for a 325 but Toyo does list it as an approved size. Now I am reading more that 315 is really the max size for the car itself without other modifications? I have never done anything suspension wise, so I am in uncharted waters for me to understand what it means.
I want to get as much straight line traction as I can without sacrificing too much performance.

What I have found currently available due to shortages everywhere:

Proxes R888R 325/30/19
Nitto NT 555 RII 305/35/19

The Proxes in 305 are on backorder until June (most places I have looked)

If I go with the 325's what else is needed to be done for them to work?
How much difference in traction (from anyone who has owned/driven on both) is there between the Nitto and Toyo?

I am open to other suggestions too, but these seem to both be highly rated, I want a street tire as opposed to a full slick, as I have not done the half shafts yet, and I need something that will break traction before I break a half shaft, but also something that will actually get power to the ground.

Any input is really appreciated as I need to get something on order soon...because I would love to actually be able to use the power my car now has

Don't underestimate the importance of overall diameter in straight line traction. It's not all about width. There's a reason why all the drag racers run with tall tires and small diameter wheels. The 325 will be very bad with traction as it has a short diameter which increases torque to the ground and decreases contact patch. If you're set on those sizes I would go 305/35/19. The extra sidewall will outweigh the 20mm width. Aesthetically, it will also fill out your wheel wells a lot better.

If you don't like the look of a drag pack type small wheel consider something in the ballpark of 305/40/18. I know Nitto NT555 R2 makes a 315/40/18. That size looks awesome aesthetically too. I think this is your best bet probably.

You probably still won't hook with the Roush but that'll get you as close as possible without a true drag pack.

Thank you for the info!

I have read that the compound on the r888r doesn't require the tires to be heated like r compound on nitto and mickey thompsons...

Anyone else care to weigh in?

Idk why people still recommend the R888R. Its a pretty old design/compound and doesn’t perform any better than a host of 200TW tires. (Discontinued RE71R, Falken RT660, Nankang CR1/CRS, and the real champ, the Yokohama A052).

falkens come in 315/30R19. Unfortunately the superior A052 (for straight line grip anyway) doesn’t offer a 315 in an R19, only R18, but I’d guarantee than the A052 295/35R19 will outperform the R888R AND the Yokes grip fantastically at cool temps.

I have the Nitto 555g2 in a 305 width, i have the roush stage 2 with an A10 and still break traction from a 40 roll let alone from a dig.

G2 doesn't hold the power.

You need the Nitto 555rii and the 555g2 on the front.
