M/T pro bracket radial

I have heard good things about them . Word I got is this tire has bridged the gap between bias and radial slicks . This is not the drag radial or the radial slick , it is a new tire called the pro bracket radial . Surposed to be designed just for the bracket racer . I just ordered the 3362R 29.5 x 10.5 x 15 . we will see . Anybody have any input id like to hear it .

Re: M/T pro bracket radial

According to their compunction chart, the x5 is the same softness as the m5. The street radial r2 is softer. But the bracket radial Looks to be a 30" radial height. 94.2" roll out, bot comparable to a 10.5 slick width?

Re: M/T pro bracket radial

Are these the ones that MT was claiming acted more like a bias ply despite being a radial.?

Re: M/T pro bracket radial

A friend of mine works for the manufacturer of many racing tires, including the Mickey Thompson tires. He said the tire is unreal. They put them on some random bracket cars and picked up ET, as well as consistency, and the drivers spoke of it feeling more stable on the top end of the track. He seems to think it could be a game changer of the same extent the "pro" drag radials have been to radial tire racing. I plan to get some and give them a shot, if I can get mine out again before the season is over.

Jason mouton said with a stiff side wall and a tube minimal chassis adjustment is nedded if any .

Yes . this is new technology that is claimed to bridges the gap between a radial and bias ply . They seem to work on a marginal track like a bias and recover just as well .

The way I hear it is Cooper bought M/T and Cooper has a state of the art manufacturing facility here in the US and a lot of that technology is spilling over into the race tires . Not sure if this is fact or not .

Mine will be here by wed . Going to test Friday and then try and defend the National dragster challenge sat.

Re: M/T pro bracket radial

Hotrod,

Please keep us up to date on how they work. I need a new set of shoes now, but the only thing that I don't like is they don't have an equal to a 315/60.. Not sure how a 29.5/10.5 would be on a 12" wheel.

Re: M/T pro bracket radial

Hotrod,

I believe you may have heard right, but M/T tires have been manufactured by a third party for as long as I can remember. This has been in the works for quite some time, and is just coming to market. I think the facility is in Pennsylvania.

Super73,

The 29.5x10.5 should work fine on a 12" wheel. We stretch the 275 pros onto a 12" wheel all the time, and they seem to prefer the wider wheel. Of course I would default to the manufacturer suggested wheel width until others have shown the wider wheel works with this tire as well.

I will keep this updated . I also found that they balance great . The only guy I know running them said that one took no weight and the other was less than an once to balance . My last set with tubes needed a lot of weight to get one of them right . I have been buying them from a local 5.80 guy with 20 passes on them and would have bought another set but he didn't have any avalible .

I have 15 x 10 wheels just FYI . I have also heard that they really like air pressure . My buddies car is a 68-72 Nova , sbc , glide , leaf spring car . It is heavier than me @ 3200 and he is set up like a stocker with a 30 x 9 radial slick . He swapped to the 28 x 9 PBR on an 8 " wheel and his last pass he had 31# in the rears . He is a bit slower than me at 7.0X and I run 6.80's on motor and im currently @ 2840 for super street . M/t says start at 15 # and work up till it spins and back off . He says he cant make them spin at 31# , but with less weight and more tire it makes sence i'll be at lower pressure . First pass will be at 20# . They should be in today and I have already fitted the rims with good metal stems . Update coming .

Re: M/T pro bracket radial

These things are still a radial . I was at Evadale this weekend and they over sprayed the track with prep . My slicks liked like cotton candy coming off them when staging . The radials wouldn't work . Bolted the old bias plys back on and went right down it . About 7 or 8 guys on some type of radial slick and none of them could get down it . Everyone on a bias ply that had any kind of suspension that worked went right down it . 4 of the radial guys finally figured it out by turning the front full loose and softening the rear enough to big wheelie . The pro bracket radial may be a good tire , but im going to stick with a bias ply for now . My rear spring rate is 200 # and I need to be lighter . 150 or 130# would be better . My leaf spring is not common and at this point Calvert doesn't make anything with a lower rate. Back half with ladder bars would fix it , but im not going that far just for a radial .

Re: M/T pro bracket radial

Thanks for the info. The tracks local to me are not always prepped the best. Think I'll just get another set of 29.5x10.5 stiffwall tires and have my fun.

Im convinced this is a better tire . I just don't have the time to fine tune my setup to it . Manly due to the oddity of my truck . If I had standard type parts id stick with it til it worked then swap back to a bias ply and know it would work anywhere .
