XTREME Street tire question

[draggin3]

can BFG or M/T 325/50s be used in xtreme street?

[NMCAMike]

Trace,

You should have received my e-mail, but for the rest to see: We will be discussing a way to allow drag radials in both P/stk and X/S while we are in GA NMRA.

[draggin3]

Mike- thanks for your email. This was posted a few days before I emailed you.

Thanks again,

Trace

[draggin3]

any word Mike?

[NMCAMike]

Trace,

We are currently looking into a MT DR tire that will come as close to the 60ft of the 28X10.5 slick. There are many options to look into and I really don't want to put weight on cars. We will have an answer soon and will post it as soon as we (rules committee) have an suitable solution.

[BlownBird]

Am I reading this right? Is pro not allowing any drag radial in Extreme street? I was planning to show up at a few events, an I run a 295/65 15 M/T drag radial. Will I be able to run using this tire??? I feel this tire would be at a disadvantage over the Goodyear that everyone is running!


Please help, I am confused...

why do you say that? 295/65 is a 30x10 and the goodyear is a 30x10/10.5...? Wheres the disadvantage?

The real disadvantage is some people cant fit a 30" tire under their car. Which leaves the 325/50... which has already proved to be very similar to a 28x10.5 in size and 60' capabilities..(which is what they are looking for) :confused:

The disadvantage would be that it's a "drag radial". It is not as consistant as the slick and radial slick in my oppinion.
So... are we saying this tire IS illegal in this class??? If so, then I am confused. It fits within the tire limitations as stated by the rules, and will pass the go-no go gauge.

I have another question, do you think the drag radial will be an advantage in the class? There is no weight break for the tire, so what would be the advantage?


Thanks for any input.

It being a drag radial has nothing to do with it being a dissadvantage seeing as its 3 compounds softer then the slicks :confused:

its yet to be seen if they will pass the guage or not :confused:

for some cars...yes. for some cars.... maybe not. The m/t radials are like i said.. 3 compounds softer, but they are a stiff sidewall tire (as compared to a regular sidewall slick most run in the class). Just depends on how the car works on radials compared to the slicks. Our car 60ft better on 325/50's then the 28x10.5's :)

[BlownBird]

Thanks Pit,
Guess I'll just have to keep my fingers crossed.

There should be a revision for the radial tire this week.

[Bob Curran]

but the tire needs to fit within the GO - NOGO Gauge that is currently in place. X/S consistantly has the highest amount of cars, if you want to race bolt on a set that meets the current rules and come race.

[BlownBird]

Any word on this yet???

[draggin3]

any word on whats approved and what not?

[Bob Curran]

Rules page it has some revisions that i think they will revise! it states that the tire is allowed but the problem is that the MFG spec states it is a 11" tread width" thus most likely not fitting the go - nogo guage the class has to follow. do you have these tires right now have you measured them as to the footprint?

IMO this class has an Identity as a true 10.5 slick class with no wheelie bars and a single power adder, Drag radial class has it's identity unfortunatley i can't run that class as it requires stock suspension, and most racers of that class have not been receptive to a ladder bar car bolting drag radials and coming racing with them even though we know the tire would be the limiting factor. It would be great to see you out racing X/S! I got to meet Chip last year in MG and he caught me sleeping in the Semi's.


Class Overview
Xtreme Street is designed for small block and big block single power adder 1950 and newer American production vehicles. Supercharged and nitrous oxide engine combinations are permitted with a maximum cubic inch of 525 depending on combinations. Xtreme Street permits a variety of race-proven modifications and performance enhancements on stock steel bodied, stock appearing vehicles, with stock type chassis and frame rails. Xtreme Street competes on a true 10.6” wide slick and no wheelie bars are permitted. Xtreme Street racing will be conducted at all drag racing events (see race schedule).

[PITBITCH]

what are you worried about it for Bob? You're goin teen's and 0's on a tire 99% of us with mustangs cant fit under the car.

:rolleyes:

how about only stock suspension cars can run a radial in X/S. ;)

My thoughts exactly! Sounds like a winner to me!

[draggin3]

it would be nice to have the ability to run over here since my engine combo fits right in but i really do not want to run a slick after running radials for the past 2 years. the radial drives way better down track than a slick. if a 325/50 (28x10) isn't allowed then so be it. us DR guys will stay away when the PRO races are close to home.

ps.. it cracks me up that some have a problem with a DOT radial competing against a slick. just a few years ago you got a weight break if you used a radial.

is there a revision?

[chip provenza]

I hope they have a answer by maple grove I really am looking forward to racing with you guys again.325/50 MT radial please.

[draggin3]

found the answer. give me a call chip.

I knew someone would go there - and you race in a class where they only allow a drag radial and a Mustang! could I race my Corvette with Ladder Bar and Slicks there? But you would tell me to build a car to fit right! same deal on the Drag Radial in X/S! you need to look at the other racers views that have help build the class to what it is!

[BlownBird]

Bob,
I am still confused as to why you are so opposed to letting a drag radial into this class. I know you are the one who built this class to what it is, but open your mind a little. We are not asking to let unlimited drag radial cars to run in this class. The cars on radials would be running with the same set of rules, just on a radial, not a slick.
Is there something I am missing here?
The 295/65 should be the max allowed.(29.6" tall 10" wide)
Just my .02
DonB.

[Bob Curran]

I would agree that the 295 should be allowed as i believe it will meet the spec of the rules. but making a "spec tire" eliminates it from the rules the rest have to comply with! also in my open mind it will Cost for me to go NMRA Drag radial racing = $60K cost for a NMRA Drag Radial racer to come race X/S = $450.00. I am entitled to my opinion, and I am sure I will line up with a Drag radial car, hope I win but you just never know it's racing, and a little abuse i get for losing to a drag radial car, thats life and I can live with that! I have seen the performance they are capable of, and they will be competative in X/S


In the over view of the class which the intent of the rules were designed

not anywhere did it mention a drag radial

And how come Management hasn't let the Turbo Cars from DR in the rules? I was for it, but that just shows the pull I have!

[BlownBird]

" Xtreme Street competes on a true 10.6” wide slick and no wheelie bars are permitted "

So.... If I were to show up with an 8 Inch slick would that be breaking the rules? :rolleyes:
Just wondering.
DonB.

[Bob Curran]

yes as it fits the the go-nogo guage if you wanted too!

[BlownBird]

And my 295/65 will pass the guage also, for width and height, so I guess they are ok to run?
I'm just looking for answers. I don't want to fight about it, just would like to know if I could run if I show up on these tires. Thanks,
Don Barnett

[Bob Curran]

that they should fit, but i don't have any to measure so i can not be 100% sure! what i was stating is that they made a rule for a couple of tires, now i don't know if they meet the guage or not, i was going on MFG specs but they allow the 325 that states a 11 tread width and not the 295 you are inqurying about which the MFG spec shows it being a legal tire. I don't make the decisions on the rules, the tire they are allowing fits the Mustangs in the Drag radial class the 295 does not, so they are allowing it, but say a camaro may not fit the 325 with a stock suspension but the 295 does, so wqith that said if the tire fits the rules it should be allowed, not writing rules to allow a specific tire that does not have to meet the same rules as the rest of us! If my goodyear measures 10.7 i am DQ'ed if a 325 doesn't fit the guage the rule states that it is an allowable tire,kind of like when they came out with a 10.5 W the sidewall stated it but it was about 11" wide

[draggin3]

i'm not out to insult anyone. i just want to show up and run for fun. just an expensive test session. the only radial allowed is a 325/50 which is comparable to a 28x10. i would think that a 28, 29, or 30" x 10" slick would have a big advantage over a radial tire.

[BlownBird]

Bob,
I see what you are saying, I have a third gen Firebird with stock suspension. I cannot fit the 325 on the car, but can fit the 295. I cannot cut enough out of the rear quarters to accomidate the growth of the slick, hence the radial.
Like I said earlier, I am not trying to fight about this, just trying to understand, and make sure I would be within the rules if I brought the car to the event.

Bottom line is Who's is ready to get spanked in XS?See Ya soon:DThanks florida man.
