It's a bad tire, a few guys that run 8.50 index switched to it and like it.

Almost every Stock/Super Stock car in the country is on a radial, unless they are a four speed car. I saw a guy this past weekend at a bracket race with the new M/T bracket radial on his car. I asked about them and he seemed to like it. The Pro Drag radial is fast and hooks good on a fairly well prepped track but 100 passes is about all you will get out of them before they have cords showing. I'm interested to see how many passes the bracket radial will take.

Yes when you spin on a radial tire you don't just lose .02-.04 you lose more like .06-.09 in the 60'. They do not recover like a bias ply tire.

Read what the previous said."Hooks good on a fairly well prepped track". Yep. I ran Hoosier 29.5" x 9" radials and they were Dr. Jekyll and Mr. Hyde off the start depending on how well the track was prepped: Hook, or spin, no in between. I'd be curious if the MT bracket radial has been engineered to be more forgiving of marginal starting lines than other radials.

Ya, everything was great until you got on a marginally prepped track,then was either hit or miss. And yes every Stock/Super Stock is on a radial,but when you go out are you on a national or divisional prepared track. A lot may have to do with how much power you are making also. Pro Bracket radial was just released from Mickey Thompson last month. It's not like a regular radial slick, it's supposed to be the pro compound on a 29.5 tire.

I was hoping to read they had developed a new 14.5 x 15 radial. I tried them back in 2004 and like everybody says, they can really hurt consistency on on poorly prepped track. My log book shows a best of 1.262 and a worst of 1.342 , and a string of those to boot. On top of that, I was lifting often because the car would oscillate side to side so bad I should have lifted on more than half the runs. You couldn't drive it out either, the only help was to get off the throttle.

Our C/SA big block Barracuda has never spun on the M/T 30*9 radials either, but it is a very good working car. I have had it out and bracket raced it some too so it's possible to never have a issue with the radials. I just like to give guys who are thinking about switching over a little disclaimer on the things we have learned. The switch from a bias to a radial is usually good for a solid .10 faster e.t. as well.

I have never run a tire that wide, but with the 28&29 10.0 tires I run the radial is nite and day better on the big end.

I have never run a tire that wide, but with the 28&29 10.0 tires I run the radial is nite and day better on the big end. I do know that on my 63 I have a standard street radial tire up front and when I went to the radial slick over the bias Hoosier QTP tire my 63 handled better all around and had no walking at all on the top end. I love how good it handles on the radials on all four corners. Course I knew I was mixing the bias QTP tires with my front radials before but I was surprised how much better it handled. Maybe with all the power the SS/AH cars make it has something to do with their wobbling problem. I remember seeing Bucky Hess's car do that at Maple Grove a few years back but I really dont know what tires he had on the back of it that day. Ron

We have been calling that radial roll. If you have a car that is very loose, front end wise,& suspension. It's seems like this can become an issue when the track may have humps or low spots to unload the car while putting power down. The radials seems to try to fight each other pushing back and forth. I have experienced it a few times, not fun usually on the big end. I run the Hoosier 10.5x30 stiff sidewall radial on the super stock car & never had a problem with radial roll. The most important thing on a radial tire is air pressure. They can be temprimental at different tracks depending on conditions, also how big of a burnout dictates how they work also, it will be interesting to see how the new m/t work & last. I have heard tons of stories about how bad radials are but most of the time seems to be user error. grncpe....I remember seeing the build on your car, nice build I can't member the rear suspension on it. what's been your best 60' on the Hoosier 10.5 x30's

The best 60' with the Hemi in it was 1.26, the best so far with the super stock 383 has been 1.33 . The same set of tires, I am actually putting a pair of 10.5 x30 light weight radials on it now. My tires are 3 years old & just wanted to get it sorted out with the old ones. So fresh rubber & 3 pounds lighter per tire. I'll let you know what it nets out to be. I need to figure out how to load pics on here now, the 383 looks lost in there lol Tom have you weighed the car with the 383 ? Curious how much lighter it may be with the 383 vs the Hemi. Ron

Racerx, forgot to mention cal trac mono leaf with bars, cal trac shocks with the Hemi . Santhuff shocks with the 383 Hey Ron , it weighed 3195 without me and a alum headed Hemi . 383 ss motor was 3050 without me. All off the nose of the car. Of coarse I had to add some weight to it as I have to weigh 3470 for ss/ja. I have been running it at 3560 ish so I will lighten it up a little also to get it a little closer to min weight. That is with me in the car. Thanks Tom. If you dont mind me asking do you know the HP that 383 makes. I dont know anything about your 383 but thats a strong 60 so it sure sounds like a strong 383 stocker eng. How fast has it gone with that stout 383 ? Thanks , Ron

I was on Mickey Thompson's web sight and they have 2 different NEW tires I am interested in. The ET Drag Radial 29.5/10.5 with the R1 compound and the Pro Bracket Radial 29.5/10.5 with X5 compound. All the specs are the same except the compound and the ET Drag Radial is 2 lbs lighter. I am running the 315/60 ET Street Radial now that is the same height but 1 in wider. I would think the first 2 would be the best of both words since they do not have any tread and are a radial but they are 1 in narrower. Which one of the 2 new ones work the best?

D-50, You may want to try asking Jason Moulton , from MT , over on Yellowbullet . He was helpful to me , though i have gone back to Hoosier radials . I have tried the lightweight Hoosier 9x30 , 29.9 dia . Was very happy but did not have enough gear . I am only a small radial guy , Hoosier 275 , with not enough power .
