Also curious to know if they sway, vibrate, and are a pain to mount and balance as I've heard?
Short sidewall because you have them in a 305-35-20?I have them on my ride right now and they're just fine but I don't drive mine in the rain. They ride about the same as the original pzeros that came on the car. In my mind the mt/et streets hook extremely well for what they are which is a short sidewall drag radial. even now as mine are far below the wear bars. The perelli's were instant tire smoke at any speed hot or cold.
When my car was stock, I could dead hook a 1st gear 20mph roll (in warm months) with 305 35 20 street ss's
They wear for shit but they do stick well. If someone gets 3000 miles out of them I’d be impressed. Mine got a little squirrelly at the big end at the drag strip @18-20 lbs. they allow the car so be driven in a fun manner even on the street vs blowing the tires off off at every mash of the gas on stock tires. The Nitto wear WAY better but have let me down on the strip when I really needed them not to. Not that the Nitto were disappointing every pass but the MT were fantastic pretty much every pass. Ultimately I’ll prefer the Nitto simply because most of my driving is street driving. I at one time had two sets of wheels one with the Nitto for street driving and one set with MT for track days.
I never drove with the MT’s in heavy rain but might be worried about it if I had to. My hellcats over the years were always toy cars.I have used both the 555r and the 555r2. For me personally performance wise I think they were about the same but I think the R2‘s would wear slightly better in street use.
