I'm leaving no stone unturned & thinking outside the box. I've been thinking about trying a DOT drag radial for some time.

Seeing I'll be running 1/8th the majority of my races this year. I decided to give the shorter dia. DOT radials a shot. I've been watching a bracket car similar to mine put down some pretty impressive 60's & ETs with a M/T ET Street Radial Pro.

Late last year Hoosier updated their DOT drag radial. It seems they are a game changer over their older model & the M/T radial. They have been working really well in both no-prep & prep racing.

The 1st link is the Hoosiers I'm going to test/race soon.

Have you already made the purchase? It would be interesting after trying these that you went back to review the best of what you’ve tried prior to compare these to. I can’t believe the price of tires, but I’m getting old.

I haven't pulled the trigger yet. Still thinking about if I want to try these before the Spring Fling Million event. I have 2 more points weekends with 4 races & 2 TnT's before the Fling. The main reason for these radials is for an outlaw, basically no-prep track in Northern NV. race in June. Regardless, I need to test these radials sometime.

I have a good many new changes to evaluate before the Fling & these radials would add to testing. I have the new T&D rockers coming, hopefully soon so I can use more boost. I have a smaller ProCharger pulley & shorter belts coming for more boost.

I'm not looking for ET; I'm searching for more 1/8th mile mph for the Fling. The shorter tire will help with that. I've been 125 mph in the 1/8th with the bracket tune, but would like to be around 130 mph.

I'm probably overloading my plate, but it appears to be the direction I'm going!

2BKING is running out of time & wanted to get nitrous on the car for a scramble button if needed. Probably needs wait for another time.

Hard to believe that what passes for "tread" on those tires passes muster with the DOT, but all that counts is how they work on the track right

I once got caught in the rain on the street with M/T DOT drag radials on my mid-11-sec Chevelle, and that's something you don't ever want to do twice.

The way I look at these new DOT radials, they are wolves in sheep's clothing. I think the last bullet statement sums it up well.

Product Description
Hoosier Racing Tire Introduces DR3 Tire


Hoosier Racing Tire has introduced the new DR3 race tire designed specifically for classes and events that require a P275/60R15 D.O.T. approved radial.


The DR3 is the successor to the previous DR2 tire.


Key features and benefits of the DR3 include:

• Purpose built construction designed to take on more power for quicker elapsed times
• New DR3 compound is designed with latest technology for optimum traction at the track under all racing conditions while requiring very little burnout
• New profile design to maximize performance
• The tread pattern is designed to meet minimum D.O.T. standards while achieving maximum traction and performance
• Tire intent for race only, not for street use

The tires are ordered, supposed to be here Mon. They did mention possible weather delays. Anyway, if they get here in time. I'll be testing them a week from today at a TnT. If not, they will have to wait for a couple of weeks.

Another reason for trying these tires was to help with the 3.55 rear gear change. While that ratio worked great for 1/4 mile, I think the shorter tires will help greatly with the 1/8th mile. The effective ratio will change to a 3.80 & we used to have a 3.89 rear gear. I just hope it doesn't wake the sleeping giant of a barely raceable car again.

The ones I have now are low run new set. The ones coming are aluminum on the intakes & steel on the exhaust.

Got the tires today, plan on having them mounted & balanced on Wed. Then have them on the car for this Fridays TnT.

The 1st thing I noticed was they're heavy & I weighed them, 30 lbs. each. Hoosier didn't list their weight anywhere that I found. Next, I thought they looked funny. I haven't run a 28" dia. tire in 15+ years. I'm sure they will look funny on the car also.

As for my calibrated thumb durometer , these are the softest feeling compound I've run. Hoosier says they're very soft but doesn't list them on their compound chart. My C30 compound Hoosier radials aren't listed either & is close in softness; these have worked great with 2 wins last fall & a win this season.

I only plan on using the new tires for the TnT & switch back to the C30 Hoosiers for the weekend's races. That's unless the new tire impresses me that much to keep them on. I'm not expecting that to happen, but you never know.

New tires are mounted and balanced. When I picked them up from the tire shop. I thought if I had another pair I would be going circle track racing. They don't look to terribly bad on the car but I prefer the filled in look of the 30" tire.

I sure hope these tires do what I want them to do.

I did measure the RO & they're dead nuts equal. I keep saying I'm not going to measure a radial again. It doesn't matter if they're M/T or Hoosier!
