High HP Street Tires

I've got MTETS R 325/50R15 for the strip, and Toyo 8RRR8 345/35R19 for the street by these Toyos suck. Has anyone here tried the Toyo Proxes RR 345/30ZR19? I've read that they are better.

Did you end up buying something?
The 305mm PS4s aren't enough bite for my new setup on the street, so I'm shopping as well.

I just sold my R888R's and went with the Nitto NT555 RII's our back and LOVE THEM.
I got the 345-30-19's out back....

That's what the shop that did my car recommended today.
I ran the original 555Rs on my '95 25 years ago, they were great overall.
Granted, that was nowhere near as fast as the '17

Did the 345s fit OK or did you have to make adjustments?
That's a lot of tire.

the 435's fit perfect for me.... the R888R's were the same size with no fitment issues.



Much better traction with the Nitto's

I started this thread back in July. Since then, I have changed from the Toyo R888R to the Toyo Proxes RR 345/30ZR19. My question is someone here, maybe CamOnlyJambroni, said he had gone to the Toyo R.

I'm looking for feedback on the Toyo R because my RR won't hold below say 60 mph, depending on numerous factors

Tires look great, but are they not mounted backwards? Tread direction looks wrong?

Not sure where or when you use the car but have a question.
This tire seems like it’s as close to a drag tire as you can get without actually being a drag tire.
That being said, compared to the MT ET Street R for example, how does it feel in both high HP grip WOT situations as well as normal road driving?
