How well do they hook up (especially on a stock Hellcat)?

How's the traction from 2nd gear 30 and 40 mph roll hits? Little slip and recover quickly or dead hook?

How's the grip from a standstill?

What do you have your psi set at on these tires at the track and the street?

Do these tires sway at high speeds (120 plus mph)?

Thanks

• The tires hook up about as well as the car can hook up.
• Standstill grip is very good, considering that they're on a car with 650+ off-idle torque
• M/T recommends 11-14 psi
• The tires sway noticeably at high speed. If you have driven enough drag slick cars, it's nothing different, but it is a drag tire... not a performance tire.

I have never used these tires on the street, so I can't comment. I'd NEVER put a super soft sidewall tire on a street car. Never. Some people do it, but not me. I religiously separate my track tires and my street tires. Track tires never see a mile of street use, and vis versa. But, I will say that once you reach the point of having GOOD tires, there's not much difference on performance from a roll. A big power car is going to blow the tires off of these just fine if the driver mod has too fast of a right foot.

And for the record, I've never used these on my Hellcat. I did run them on my 1,024whp Mustang at the track. Low 9 second car. They did well.

Awesome time on the Mustang.

Definitely agree that cars with a lot of power will make any tire slip but with these tires it seems like you’re able to ease into the throttle more easily without losing traction? Obviously this is based on the skill of ones right foot but having sticky tires like these makes it easier I’m assuming?

When you said MT recommends them at 11-14 psi is this at the track?

I may have heard from one or two folks that they do sway and others say no, is this sway at high speeds an unstable scary feel? Also not sure if they have a speed rating on these tires, do you know happen to know if they do?

They are great tires as long as you know how to feather your gas pedal properly.

I last ran them at the track @ 20psi, 9150da, 90 degrees, stock wb redeye 11.367. feathered through first and WOT for 95% of 2nd gear. On the street I run them at 30 psi and they are comfy to drive. At less than 25psi you will start to notice sway at higher speeds. I took my redeye to 184mph on stock Pirellis and did not notice the sway that I notice with the M/T's @ 120mph and up, but different tire for different purposes...

11-14 psi @ the track

No speed rating as they are intended as track tires that are ok to drive to the track on NOT street tires that are ok at the track. speed rating = 98798465132198189mph for 1/4 mile at a time.

Scary? Depends on your understanding of the car and high speeds. Sway at high speeds in a controlled environment, not scary at all. Sway at high speeds on the street in an uncontrolled environment, could be scary.

Not spinning tires is all about throttle control. Ill spin the treads right off these M/T tires or any other tires if I want to. It's easy to do even without the line lock and the traction control partially engaged.

In short, if the tires aren't swaying, then you're over inflated and aren't getting the maximum traction. The low inflation rate is needed so the sidewall can curl and bite during launch. This soft sidewall is what causes the sway or shimmy as you're traveling at high speed at the big end of the run. I'd never in a million years drive these on a public street.

I had 305 35 20 s/s on my stock powered car and could dead hook 20mph in first gear with caveman foot (no rolling in to it necessary). From a dead start, some feathering needed but hook up fast. Very quiet tire and experienced no sway at least all the way up to 150mph. Street driven at 28psi.

Well dam I'm sold looks like MTs are the way to go.

Just pulled my Street SS' off in an attempt to solve a highway high speed wandering issue after lowering the car on Mopar performance springs, installing the Street SS, and a slight alignment. Problem solved with proper high performance on-highway tires. The wandering I found to be almost dangerous but definitely concerning. The car shoots straight again at very high speed open highway blasts. As others stated above I will never run the drag radials on the street on this car again. On the track @ 15 PSI it almost hooks solid. You do feel the wiggle coming through the traps but never thought much about it as it was expected. Again on a quick 1/4 mile burst @ 123mph hardly even a thought. On the highway the extreme wander @ 30psi really became evident above 120 mph to the point I wouldn't take it there anymore.

Of note the Conti DWS06+ i put in place are a huge improvement to the factory P Zeros. I went with 315 35 20 and fit very well on the lowered widebody. Car rides / handles better than new now. I'll post pics when the sun shines again.

I run the M/T Street R 315 50 17 on a forgestar 17x10 wheel. Driving to the track I set them at the OE recommended
32 psi. Once there I drop them to 20 run it see what it does , then change it .5 lb increments ( usually Lower). I have worked it down to 17 once in a while. It does waller around a bit on the big end , but its normal and to be expected. M/T
tech told me not to go below 14. I run M/T skinnies on the front starting at 73.

How low of a speed did you hit it at with that little slip and recover with 800rw?

At that power level whats the lowest speed you can hook without it slipping?
