And on the 8th day, God created M/T ET Street Radials!

Man, I love these tires! Great street manners, and they hook like glue at the track!

First time in about 5-6 months that the weather forecast in Gainesville, FL was upper 50s for the low temp. Front going through, no clouds...think I went racing?


FYI, car is a 1970 Nova with a small block 383, TH400, Cal-Tracs, pump gas, 3500 lbs race weight, full exhaust with tailpipes, full factory interior. Pics of the details are on my webshots page in sig.

So I threw my fire jacket and bottle in the Nova and drove her out. Got there around 6:45 and already the DA was 2000 feet and dropping.

1st run, 17 psi in the 275/60/15 tires, and launching off the footbrake at 1800 rpm without the spray:

.021 - light
1.550 - 60 foot
4.645 - 330 foot
7.278 @ 93.08 mph - 1/8 mile
9.568 - 1000 foot
11.526 @ 114.53 mph - 1/4 mile

Oh yeah! Wheels up a good amount and dead hooking, DA down to 1534 at 8:15 pm.

So I figured "let's add the juice and see what she does."

Same tire pressure and launch rpm, nitrous hit about 10 feet out:

.003 - light
1.483 - 60 foot

4.297 - 330 foot
6.696 @ 102.11 mph - 1/8 mile
8.786 - 1000 foot
10.573 @ 125.55 mph - 1/4 mile

Same deal, mf'er dead hooks wheels in the air and I got on the bottle without any chirping of the tires. Time was 8:45 pm, DA down to 1125, bottle pressure about 900 psi.

Good night, aired the tires back up to 22 lbs and drove her home. I should do this more often!

Sorry for the long post, but had to share. Just something about driving a 10 second pump gas small block out to the track and ripping off good time and then driving home.

Ah it sounds like a great night at the track and such a sleeper. Doesn't look that quick :D
What kind of life do the tires have driving on the street?

Sleeper? Thanks, but I think some Rally wheels might help out the zzz factor!

Not sure on the life yet, they are sticky and soft. Buddy of mine with a 95 Firebird Formula got 4,500 miles and about 60 passes from his last set, and in my opinion, they're 10X better than BFG or Nittos, and still work well in the rain. I'll have to see how well mine last, got 20 runs and about 1,000 miles on em right now.

Re: And on the 8th day, God created M/T ET Street Radials!

looks like a real nice street car, not like the 71 Duster a co worker drives. The big cam in his 340 makes all the fiberglas bumpers, fenders and hood shake so bad you would think the parts would crack and fall off the car. The sad part is he can only get it to turn mid 12's. I know that is a respectable ET, but not for a 2600 lb shell with mega bucks in the motor.

Hey check out this plate they issued for my Nova. Had there been 273 more people in line in front of me it would have been 281-VLN and I would have just had to send it to you :D

Nice job Derek,

My buddies run those tires on their cars. One has gone 10.40 N/A (9.90 on the juice) and the other has gone 10 teens N/A.
Both have seen low 1.40 60ft times on our unprepped street legal night conditions.
Both of course are driven to and from the track.

Because of my 4.10 gears, I haven't been able to try them yet. But with a switch to 3.73's over the winter, I'll be buying a set.

Might have to try some spray as well.....see if I can't hit the lower nines.

Congrats!

Ron

Switched from Indy Profiles to Street Radials on the rears and now I screech second gear plainly and don't "railroad" on the curves as compared to the bias ply Indys. Recommend them to all. Yet to go to the track and try to better my 2.00 sec 60 foot times. This is a must do upgrade.

Thanks for all the comments!

Philip,

I've thought about personalized tags, but that's a new twist! See if yuo can find the 281-VLN holder, I'll make him a deal he can't refuse! :thumbsup:

Ron,

I think you'd like these tires. A friend with a 71 Nova, 496 pump gas car and a 'glide has gotten a 10.31 at 129 mph best with a 1.44 60 foot time on the same night I was hooking up with them. If you get them to stick, they 60-foot better than slicks or ET Street biad plys.

My 540 buddy schooled me on the 60ft times this last Sat.
He ran a pair of 1.38's on the M/T 295's To my 1.40's on 9 x 30 radial slicks.
But I schooled him on ET's, 10.12 to 9.97.
The interesting thing though....when he lined up wrong, he spun and ran 10.60's. My 60 ft times were between 1.402 and 1.412.......ET's between 10.01 and 9.97.
I'm intrigued.......I'll get the 3.73's in the car and try em!

Derek: all the hype has sucked me in and my ET Street Radials should be here this week. I picked up a set of Weld Pro Stars on fleabay and ordered the MT's from the factory (had free shipping) and I hope to be hooked up for this Wednesday's TNT. I have been closing in on 12's with street tires and hopefully now I can use that converter I paid so much for. The last TNT I went to I was running prety good until the last run and I dropped off two tenths and few miles an hour. Got home and found a bad coil wire (factory MSD wire). I had enough stuff left over from my cut to fit wires and made a new one and it runs good as new.

I got 15x7 wheels with 4.5" bs. I knew I could get a 15x8 with 5.5" bs in but only after a fair amount of "adjustments". I ordered the 255/60/15 MT's and only gave up 0.9" of diameter and 0.4" of contact from the 275/60/15. Hopefully it will cure my slight rubbing issue too.

Bruce,

I think you'll like these tires. I know I'll buy another set when these wear out :thumbsup:

I ran them again this past Saturday night in bracket racing when one of my slicks developed a leak from the valve stem.
5 runs with 60 foots ranging from 1.549 to 1.537 over a 5 hour period!

My MT's showed up yesterday afternoon, too late for Wednesday TNT, but I'll be there next week. Next season I am going to start running on Saturdays for points.

By the way, I am looking for a pair of Weld Pro Star 15x3 1/2 front runners if you happen to know anyone getting rid of a set.

Re: And on the 8th day, God created M/T ET Street Radials!

Hello,
New guy from Massachusetts. Had to chime in on M.T. ET Streets. used B. F. Goodrich Drag Radials but couldn't get consistant 60 foot times. The M. T.'s straightened out that problem.

I'm a lot slower than you guys running a naturally aspirated 406 in a 72 Nova with a 700R4 and a 4.11 12 bolt. It's a full interior car that's all steel except the hood, weighs 3488 without the driver. I'm a 240 pound husky toddler. Car runs 12.02 @ 111.41 MPH and I drive it home with the Air Conditioning on.

One note on tire pressure on the street. Mickey Thompson recommends running 75% of the maximum PSI stated on the sidewall of the tire. In my case that work out to 33 PSI. I've driven them in moderate rain without incident. I was changing the B. F. Goodrich's every year. Don't know how often I'll need to change the M.T.'s but they feel so much better on the street and at the track

33 pounds? :clonk: Wow, I'd never imagine running that much! I have 22 psi in mine for the street and they handle fine. Guess to each his own, and good to hear they work that high on pressure.

I used to run 30 pounds on the street until I read the article on www.mickeythompsontires.com/tech.php?bulletin=s3
I figure the extra pressure lets the tire run cooler on the street. I don't street race and I find my Nova drives well at 33 pounds.

Interesting read, but as I stated before, I guess each works a little different. The rec. pressure for a slick under 30" diameter on a car over 3000 lbs is 16 psi and higher?!? I run mine at 14-1/2. Anymore and it burns out the centers of my tires.

ET STREET RADIAL
On the racetrack DO NOT use starting pressures below 11 psi.
Recommend pressures for:
P295 and larger sizes: 11-14 psi
P275 and smaller sizes: 12-16 psi​
On the highway we recommend running 75% of maximum psi stated on the sidewall of the tire.

Derek, you are talking about your MT ET Street radials right? 14 1/2 looks to be right in the sweet spot.

I run 15 pounds pressure at the track. 33 is what I run on the street.

No I was referring to my ET Drag Slicks. The radials I run at 17-18 psi on track and 20-22 psi on the street.
