X2

My 517 C.I. six pack piump gas motor made over 600 HP to the flywheel and 545HP to the rear tires on a dyno jet chassis dyno here in Bend several years back,
The M/T 13x31x15 ET street bias tires would almost dead hook at 9.0 lbs. on 10 inch wide wheels on my old Duster on the street, 1/2 to 3 turns max weighing 3450 Lbs. total ready to race with 50.7 % weight on the front tires I raced it with all three sets of tires on the car, the bias plies 13x31x15 ET street tires where the slowest ET and MPH at the track and the 315x60x15 M/T ET Street Radials ET and MPH where almost identical to the 10.5x31x15 M/T drag race slicks, the car would cross the finish line at 6500 RPM at 134.+ MPH with the slicks and cross at 7000 RPM with the ET Street Radials at almost the same MPH and ET I never drove that car with slicks on the road so no input about that
I do like the M/T ET Street bias ply tires better on the street with decent HP compared to the M/T ET Street radials I used

Thanks, Don. Retired now, may pop in more from time to time. But ya never know.

28 by 11.5 QTP..... 15 by 10 wheel with 4.5 backspace. This on a 70 Duster, super stock springs in stock location

67 barracuda. Dana narrowed 4"/side, minnie tub, 15x10-3.5bs with a 28x14.50x15 QTP. Biggest tire that will fit in there. Just to give an idea.

Do those fit inside stock wheel houses?

Yes. It had been a while since i had that car( 70 b3 duster with W5 motor, many members here know the car)

If you want to see what the tires look like on it..... go to youtube.....” don’s wheelstand”
You can see how the tires fit. They were Just barely inside the wheel lips. Again 10 inch wheel in the video, so tire lays out more than wgen i had 8 inch wheels on it several years earlier
With more backspace tire would rub to inside on s/s springs. Its important tire is centered in wheelwell

See my post above...Highly reccomended.

My car might make 450 crank hp, it’s a 72 swinger with a 383, 4 speed with McLeod clutch, 4.56 gears and a spool, ss springs and 90/10 Calvert shocks up front. 255/60/15 mickey Thompson drag radials and I promise if your trying to hook on the street the MT drag radials aren’t the way to go, they are an awesome tire but a stick car on the street isn’t going to hook very well with them.

From a stop if I dump the clutch it’s useless, from a 10mph 1st gear roll it spins 1st 2nd and into 3rd, from a 2nd gear roll it’s ok. After my radials burn off I’m going to try a bias slick. If someone can hook a stick car to the street through the drag radials please fill me in lol
