Sorry if this is the wrong place? I did a search and did not find what I am looking for. If possible, I would like only those with real experience to comment. I am in the process of purchasing new rear tires for the bracket car and I have some questions. My car is a 1969 Road Runner/Satellite 3200 lbs foot break with a W2 headed small block. I will be flashing the 3500 RPM converter from 2500 RPM. My questions: Does one tire bite better than the other at the start? Does the surface prep matter? Is one more stable at speed? Does the radial need more burnout heat than the slick or vice-versa? How many runs will a radial take before losing grip? What radial would you recommend? What slick would you recommend? I am looking at 26-28 by 9 wide on 10 inch wide wheels
Thanks for the help, I only want to do the purchase 1 time. Allen

I run a 28x10.50 Mickey Thompson Pro Bracket Radial. My Car runs 10.50s and 60s in the low 1.4s. I have been super happy with these tires, they dead on hook 99% of the time on any decent track and I have only had a couple of runs where they spun enough to really lose ET(very poor track conditions). They are also wearing very very well, I have around 75-100 runs on them and even some street driving and they still look brand new. I really like the radials, the car requires zero steering input down track, no walking around in the tires like a bias ply tire.

After years of running bias slicks we now run a M/T pro drag radial. Our car runs better with the radial but it has always hit the tyre hard. Radial has a different set up suspension wise. I've never noticed any difference stability wise but we've never gone over 146 mph but the car is heavy. We usually run 19 psi in the Radials and had to run around 13 in the bias plys to stop wadding them up, We think we may improve with more pressure looking at some of the vids. The radials almost always dead hook with a big wheelie, we've destroyed 2 sump pans so far and damaged headers, steering stuff ,K member and pushed a wing into the door. Switching to Santhuff shocks (from Menscer valved Afco's) was a good move, they really calm the landing down.

I'd call or email Mickey Thompson as they will help you. The latest and greatest tire according to facebook is the PBR (Pro Bracket Radial). Alot of guys running them and getting TONS (300+) runs out of them and say they are deadly consistent with a small burnout. Now the guys I see posting this stuff have adjustable shocks and run at big money races were I'm sure the track is spot on. There are some guys that run them at my local track. Some do well, others have issues hooking up all the time. From what I have witness 1st hand is they work well on a decent track, but when you spin there's no recovering, your going to be a good 1 to 2 tenth off the dial. A Slick is more forgiving IMO. Thank you

I think the PBR is the way to go. It hooks great on national event prep tracks ( NMCA) and it hooks great at bracket tracks through the dead of the summer and even in the cold. I see you are from Georgia. My car has gone 5.90s at silver dollar with the temp in the 40s and gone down Atlanta in the hot dead of summer with no issues. I’ve been 9.40s at 3585lbs on the 29.5 x 10.5 PBR.
The “it won’t recover” is a myth. It recovers. We ran at a race in Tennessee that had water seeping through the track and mine left wheels up, went out and spun and then recovered. The PBR is not the old hard radial design. Most folks that I know that didn’t like them either didn’t have any suspension adjustment or were not willing to work and adjust. The bias ply wads up and hides a lot of suspension issues.
I am a big fan. I ran ar Silver Dollar a few times in 2016. I now live in Mississippi. Would you run the radial with CE adjustable rear shocks and MP Super Stock Springs?

Once I figured out what the PBR's liked I found them to be very consistent even on poor tracks. For me a medium burnout the first pass and then a very short one after Really not.more than just enough to clean them up from driving to the line.
My car is very heavily and it is much more stable with thePBR's than bias ply. I run between 18-20 lbs.
Ok

I’m a believer in the PBR. I’ve run both ET Drags, and now PBR’s on my Satellite. The PBR was quicker in 60, and every bit as consistent. It was faster on the big end with no other changes. The car also felt more stable at speed than with the ET Drags. The only nod I would give to the bias ply tires is the look (I love the old school sidewall)
I footbrake, but I have a number of friends running 28” PBRs with a transbrake in 9.90 & 10.50 cars; both hook & book with no issues, those guys are also sold on he PBR.
Is there anything wrong with a bias ply slick on a bracket car? No. You’ll likely be just as competitive with either, but the PBR is a firmer tread compound which leads me to believe it will last longer (???... purely conjecture at this point, but I am 2 seasons in on my first set, roughly 120 passes and they still look pretty good.) I’d say they are simply a step in the direction of progress.

I would suggest the best shock you can afford . I had ranchos into low 11s . Now have radial valved dbl adjustable Vikings on rear , far better .
Yes the pbr will walk out not just spin up if it turns more often than not . I went 135+ passes per set . Needed solid burnout , no " just haze them " or i would turn/chirp

While the PBR may not recover as good as a bias tire it DOES recover and when it spins it doesn't shake the car apart like the ET street radials do. My car needs DA shocks on the front and once I learn more about that setup I will be able to hook this thing in a car wash lol.

I use the m/t et street R radial. 325/50 with 18# never spun out of the dozens passes I put on them last summer. Street/strip deal with caltracs and in the past with several different brand radials, either they hook or they dont. With the et street r hook every time at different tracks. Awesome tire with the R2 compound wear better on the street than the others I have used. I would buy them again, but I'm now looking at the sr radial street tire because it has the same R2 compound. I drive more street than track.
