I have the MT ET Street R bias and have run them on the street at 26psi. No issues whatsoever... A5 trans, 4.56 gear bla bla...
Having said that, I'm 50yrs old and my hot-dogging days are long behind me... So, as far as driving like a law abiding citizen, and taking corners in the same manner as 99.9% of the other folks commuting along the road... they are absolutely fine.
Now... I have these tires for the track, but have been lazy in changing them from time to time and have ended up driving on the street with them, and, have driven to/from the track on them.
90% of the time, on the street, it wears bfg radials up front and the ET Street s/s radials on the rear... not sure your power level or what you are looking for, but that s/s has a lot of "street" traction.
What are you wanting to do with the tire?
@RangerJoe runs the R bias as well (stick car)... maybe he will chime in.
