NT555R drag radial help!!!

Kay, so I have a new set of 275/45/r17 nt555r drag radials on the back of my 92 fox. I took it to Pomona a couple weeks ago, and tried to launch it at about 4500 rpm and 15 psi. NOTHING BUT SMOKE! it has a 5 speed and used to launch okay like this on BFG DRs and stock rear suspension!

In conjunction with te new tires, now it has torque box reinforcements, tubular control arms and comp engineering drag shocks in the rear.

What is the problem? What can I do for some traction?

Not an expert but what if you launched a little higher?
Then again lower?

That's cause 555r suck compared to bfg dr, they are more of just a softer street tire. They will become a little better as they are broken in but still nowhere near the best

Ha yea after I bought them I started reading more forums and the general consensus is that they suck. I've tried 5k launches and4k launches. I know they're not great I just want to see if anyone knows a way to make do and get some traction.

What psi is ideal? What type of burnout should i do?

Don't know about the psi, but watched a shelby make 5 passes and his best launch, he didn't heat the tires up at all.

I tried a set on my car with lowers, uppers, drag springs, and Lakewood shocks... I never really could get them to hook but the closest I got was runnin 9 psi and doin a big a$$ burnout, I kept doing the burnout till I could feel them trying to push the car foward

Thanks for the info guys. Anyone else have any experience with these? I'm getting mixed opinions, some say high psi with little to no burnout, and others say low psi and a huge smoke cloud haha.

I wouldn't say they suck. If you can get a 1.7xx then they are fine. I launch at 5500 on 555s non R and get 1.81x 60' foot times. Heat the R compound super good then slip and dump. 1.75xor better can

lowering psi will not help help much. As stated, they are a hybrid tire. they sacrifice forward traction for cornering. 1.7s are still easy to attain. These threads are all too common. You are not going to buy a DR and instantly nail 1.5 60s.

psi should marginally less than street.

On 555Rs?? That is street tire territory. You have plenty left in the "tank". Go do it again That is the fun part no?

A drag radial is very finicky. A huge burn out often 'activates' them. Depends on the tire

Non r? I believe they are a true race tire that requires warming for road racing. The nt05R would be for Drag and some street

I believe the nt05 r would hook less since it sacrifices forward traction for road race traction.

They aren't made for road race. They are a drag radial tire

Re: NT555R drag radial help!!!

I wanted to add that the MT tires are proven over and over. They're fantastic drag radials for the money.

I am glad you brought this up as I was thinking of a different tire.

Yes, the NT05R would hook well but I would still go with the MT tires for the money.

NT05s are street tires. I run them around and they are awesome off the track. They hook pretty decent on the street, but I wouldn't expect much out of them for drag racing

MMFF did a comparison a few years ago when they launched:

Not true at all, NT05R is a drag radial designed for drag racing.


I will concede that there are better options out there than the NT05R, but for the price you can get them for ($250/ea or less) and the mileage you'll get out of them I think they're a good deal IMO. If you're REALLY serious about drag racing you should be getting 15" wheels and MT ET Streets though.

I also found this pretty helpful when I was deciding what DRs to pick up for street and strip duty. I was originally going to run them all the time, but decided down the road to pick up another set of 18x9 wheels and run 275/40/18s all around for better cornering. The DRs only go in when I want to do some nasty straight line speed.
