I run QTP’s on both my cars. Had them on the dart also when it had a 4 speed. They worked well.

A buddy of mine built a '87 notch mustang with a grand national engine. Flat hood, stock interior, other than a few gauges and steering wheel, stock seats, and shifter, no cage or bar. Just had welded in subframe connectors, the kind that you cut the floor for. Stock suspension. With the grand national engine and trans, 3.73's and a set of McCreary ( american racer ) L60-15's that car went 9.72@142, driven to the track, and it still got almost 30 mpg on the hiway.
That car made us A LOT of money. And those tires worked great.

M & H 275-60-15 bias plys. On my third set. Drive more than race, but 3800 # car went 1.52 on them through the pipes.

Lots of buddies run American Racers too. AR is less $$ than the M & H.

Driven many miles with QTP's. Just stay out of water and rain or slow down extremely . They are wrinkle wall types with the right pressure.

I recommend tubes with the QTP’s.

I hear you on the wet roads part, I've been caught out in some rain with the MT drag radials and even those were a little spooky.

I've heard of a 69 Dart going on it's roof on a warm sunny day where some water washed across the road in a low spot.

My boy Curt did a Ballerina dance with his Duster and kissed the wall on the BQE coming from the now defunct E-town in light rain against my wishes while wearing M/T ET streets. I had told him to slow her down, and whali-whoop, it all happened right in front of me.
QTP's are no better.
I always keep a keen eye for puddles, open hydrants and just lay low if rain catches me out there.
On dry pavement, they are chiclee as they say in Spanish as Chewing gum.

Has anyone tried the M&H Racemaster?
The DOT street version has more tread then the M/T does.
I was looking to give these a try.

I use them. Been using them on this car since 2004. Due for a new set and I'm going to replace them with the same tire.

I want to put the American racers on my dart. I really like the look, I remember lots of guys running them when I was a kid. I want something more streetable that an ET street.

What size rear wheel and backspace, would work best on a Demon/Duster
with the above mentioned QTP tire?? I have a stock width 8-3/4 with a
4.10 and automatic, and stock leaf spring location. I was thinking of using these tires too??

Same ones I use at the strip for my Mustang, Don. That tread depth scared me, so I also have a set of 295/55/15 M/T ET Street S/S that I use for the street.

Good to see you posting Pat

What offset/backspace are your wheels? Stock axle width?

Please elaborate.

Yes, I would like to hear how it's easy as well. I spent years trying to hook a radial on a pretty nasty 6spd Fbody GM...going against other racer's advice in the process. When I finally did switch to ET Drag Bias Plys, my 60ft dropped 2 tenths immediately. More importantly it stayed consistent. When trying to launch a manual, track prep, pressure, and suspension are a magical combination. And, that combination usually only works on that track on that day. No doubt, they have the potential to go faster, but save yourself the headaches and run bias plys.

I've bracket raced more than one 4 speed car when I was a lot younger and willing to do the maintenance needed to do that, no more
My last halfway fast(9.99 in the 1/4 cork up through the air cleaner with full exhaust N/A ) pump gas street car with a good converter and a 727 tranny would get real ugly in a heartbeat at speeds above 55 MPH when I went to WOT on a less than perfect surface road on M/T ET Street Radials, not so on the same size ET Street bias plys
Trust me on this, don't get hurt trying to make a radial hook up on a high HP street car under normal driving conditions unless their real big and wide

Dang, you had to ask me lol. Yes stock axles. I honestly dont remember if it was 4.5 or 5.5 backspace. i will ask some buddies who have done the same thing, i am pretty sure 4.5 but dont want to swear to it

I am curious if ANY of you with over 500 HP can hook from a dead stop???
I have ET Street R's bias and I cant hook down low whatsoever.I av roll out in 1st and short shift 2nd then roll into it hard so 2/3s of the way through 2nd I'm at WOT then click high and stay hooked,,,most of the time.
Also use 31 X 16.5's. Ay the track I use 10.5w M\T and they work very good
