Anyone have any experience with M & H muscle car DOT drag tires? I'm looking at trying a set of J60 x 15's that are similar in size to the 255 60 x 15 Comp TA street tires that I run on my KR. Is there a better option than the M & H tires?
Thank you.

Sorry, no experience with the actual tires, but hey had some cool logos back-in-the-day.

We ran a set of M & H tires on my 68 gt500 KR back in 85 or so at the muscle car shootout down in bowling green KY. They really hooked up good off the line as we made it to the final round beating a Hemi road runner but red lighted. Look in old muscle car review magazine as they did a good story and my car was on the front cover painted blue with white lemans stripes at the time. I sold that KR to my cousin who restored it and it was a loaded car automatic with A/C so it wasnt an ideal race car having the extra weight from the factory A/C up front it was nose heavy and all the a/c was on the car when we raced it. When we ran the marti report on this KR back a few years ago we found out it was the ONLY 68 shelby built with factory headrest seats and it was on the build sheet and kevin marti did a story on that in an old mustang monthly article.

Don ,
I ran them in the past and they are very soft rubber . This obviously gives better forward traction on the street especially with 16-18PSI, The tread pattern keeps them legal and they should last about 5,000 miles if the "burnouts are kept to a minimum. On the Mustang I ran them on ( 450HP 289) the strip times were the same as slicks. I have also found similar results with "modern" drag radials. The ETs are only a tenth slower than a conventional slick on my Shelby with the current 525 HP engine. Street traction" is greatly improved over a "normal" harder rubber radial.

I run the Mickey Thompson ET street drag radials. The 255/60-15 fit nicely on a 7" rim. Tires work really well, and hook up without having to do a really aggressive burnout.
Such as this. lol
Thanks guys for the info. I like the tread and sidewall look of the M & H tires so I think I will give them a try. Any thing to be aware when mounting or valve stems? Should they use the bolted style stems.
Not to change the subject, but I just heard that a 2020 GT 500 was able to brake into the 8's at Bradenton. How about a 8.97 @ 154 mph!
Metal stems are an NHRA requirement. At minimum of 16 PSI you won't need to add screws into the beads. "I" usually put a small paint mark where the valve stem is on the side wall to be sure the tire doesn't slip on the rim.
That is fast for a heavy late model. I hope to get my '66 into the 9s later this year. Time will tell , if the "all motor" combination is up to it. That would be an accomplishment for a no tub , no sub frame connector, small tire , combination. Well in "my " opinion anyway.
Randy
Thanks Randy on the tip with the paint mark and bolted valve stems.
I believe you will make the 9's on all motor this years and keep us posted on your progress.
Been trying to locate a suitable 68 fastback to drag racing again, as I sold a SS/HA 69 CJ when I moved to Florida from Pennsylvania. Would prefer a manual this time, as I missed a very nice roller back in July.
Too many of the cars have been back halved poorly. I think the left leg and right arm will be OK for a few more years, so I'm anxious to get into something soon. Would be nice to find a former C/S or SS/F old school roller or complete car
I run them on the street on my Eliminator, very sticky. Have them on 15x7s and nothing special about mounting.
What size are you running? Looks like 275 60 x 15's. I was looking at J60 x 15's but I like the look on your car. No wheel lip or leaf spring interference?
Scuffed and painted a set of 15 x 7 black steel wheels today for mounting and found the old Lakewood traction bars with J-bolts up in the attic.

These are the J60s on 15x7. No interference but they are on a Cougar. If you really are concerned on fitting these in a mustang wheel well I could put on my Shelby to see.
Are you running longer spring shackles or air shocks? Your Cougar sit high in the back and I like that look. No concern with the J60 x 15's as they are the same diameter as my 255 60 x 16 Comp TA's. The 275 60 x 15's are 1" taller diameter and that might be a concern.
Unfortunately my replacement leaf springs have a lot of arch. I bought them probably over 25 years ago to replace my broken leaf. I actually have lowering blocks in it right now to get a good stance. My brother and I have been talking about rebuilding the stock springs to get the correct arch and look back. Good eye though!
I like the stance on your Cougar, as it is old school with the rear lifted. When I bought my KR back in 1981, it had 275 60 x 15 Comp TA's but with air shocks.
What front tire size are you running to get the forward rake? I use 215 70 x 15's as they are about the same diameter as the 255 60 x 15 rear tires.

F60-15 Polyglas up front for the Day 2 look. I'm also running 620 coil springs.
Did u have to roll the fender lips on your cougar (like the boss cars) since biggest tire from factory u could get on 69-70 cougar was f-70-14?
Ed
they are not rolled front or back and do not rub at all. But my 235/60s on my Shelby rub with rolled lips. I think the design shape of the 69-70 Cougar fenders allows the clearance, as they would probably most definitely rub on our 68 Cougar.
Wonder why the boss 302 cougars didnt get f-60-15 tires with 15''x7'' wheels like the boss 302 mustangs if the bigger tires wouldnt have a clearance problem unlike the boss mustang that had to have rolled fenders for bigger tire clearance. The boss 302 cougar eliminator was mercurys top performance car and being heavier and more expensive than the mustang u would think they would have had the bigger tires and wheels if not a fender tire clearance problem and in 70 all cougars and mustangs had the beefed up front suspension like the boss cars to handle the bigger tires.
^^^ yes, another oddity between the Cougar and the Mustang.
The Boss 302 Eliminators also had no outside badging/emblems/designations announcing what was under the hood either.
