What tire setup gives max speed

[NS_Stinger]

I have the potenzas but once I hit 135 it goes limp I’m guessing the ecu or the tcu has part of this plus I have a 2019 that’s AWD 3.3

Your car being an AWD in America likely came with the all season tire package which means it would be limited to 130mph.

Possibly but I hit 135 every time and the RMPS just stop and drop even foot fully on the throttle and down hill

The limiter cuts power. but you get a few mph over the limiter, like yours evidently does.

The solution, and answer to this thread, is to run something like the 155/70 spare, but on a 22" wheel. The extra 6-7" diameter gives you about a 25% overdrive to go past the (rpm-linked) speed limiter, and the 4" width reduces drag (traction not being a limiting factor).

All these replies and still no right answer...

You gotta get the tires with the white lettering on it, those is proper zoom zoom race tires.
