I want to mount one of these on my stock rims. Mikem did it on his rims with no problems. The ET streets (3743) require tubes which cost another $55 each. The ET street radials (3743R) don't require tubes I dont think. Is there a difference between the two types of tires? Which ones should I get?

 

Also, is there another brand of tire I should consider instead of the Mickey Thompsons?

 

I ran the 3743's last year without a tube on my stock rims and didn't have any problems at all. I think the radials will perform as well as the bias ply's or at least I think they will. Anyway that is what I am going with this year. I would like to hear what others think about this also.

 

They work without a tube?

Is it dangerous to run it without a tube?

 

They also say

 

We run the ET streets without tubes, they just will leak out and go low in a few weeks if you don't keep an eye on the pressures. We pretty much just use them on the track and air them up each time we go. And no it isn't dangerous, just inconvenient to some.

 

Anybody use the Nitto 555R? I wonder how it compares to the M/T tires

Ok I feel better about this now. But what's the difference between the 3743 and 3743R besides one being biasply and the other being belted?

 

I tried the 555R's and they weren't bad but when I changed to the MT's I knocked 4 tenths off of my ET. Could have been the difference between the 17" MT's and the 18" 555R's though. The 17's gave me more of a sidewall to take up some of the shock at launch.

 

i did when the car still had 3.55's and the best 60ft was a 1.87 not bad but the mt radial will be alot better and you can drive them on the street until it rain's and then your in trouble,for the track go with the et streets my best 60ft was 1.57 good luck and see you in april.

 

If you plan on driving on them (on the roads) to get to the track, I would recommend the radials. They have a little more tread than the ET Streets (see pics below), which is helpful if you encounter a little water along the way. I usually change mine at home, and then drive to the track. I hate trying to fit two tires/wheels and a floor jack in the car, plus then I don't have to leave my street tires/wheels & jack laying around in the pits.

The ET Streets (3743) uses an M5 compound, and the Drag Radials (3743R) use a special R2 compound. Comparatively, the R2 is slightly softer than the M5 (see Mickey Thompson Tech Specs).

And the radials hook plenty well. I know JDM ran as low as 11.60s on the 275/40-17 M/T drag radials.

 

I am getting spare rims so I will be swapping them out at the track. I won't be driving these on the street unless I don't feel like changing them for the ride home. I know the M/Ts are terrible on the rain.

Right now I'm leaning towards the 3743 Biasplies.

 

I didn't use tubes either. They never really dropped air, that I could tell.

 

I run the ET Streets without a tube also and it gives me consistent 1.6 60 ft times where the Nittos would never go under 1.8. I even drive on the ET streets to the track about 40 miles ( not good for tread life) and they are fine as long as I stay clear of water.

 

That is the new tire we will be running for Ultra Stang class at FFW this year. I haven't had a chance to put them on the car yet though we did have them mounted already in place of our ET streets. Until this turbo gets tuned we will be frying the street radials (Fuzion) that we originally had put on in place of the factory crap.
