Hi Guys

[jacobgiles]

...

[Darling]

WHO is going to be manning the trailer at Bradenton??

[Jason Moulton]

We offer our Sportsman S/R that works great with the ET Street Radials. We have a 24X5.00, 26X6.00 and 26X8.00 in 15 and 18" rim diameters.

Thanks,

Jason Moulton

[Wheelycool]

Thanks to all for your support of Mickey Thompson here at the Bullet!
The object of this tech tread is to help our customers and increase communication with those that use our tire and wheel products. Please post any pictures, videos and questions surrounding the application of M/T products and we'll be there to respond.
Thanks,
Carl

[Wheelycool]

Ben and Aaron are at Bradenton ready to mount and balance!

Thanks!

[kfickler]

It was cool to see Dan start the year so strong. Has he started adding divisional races yet?

[Monty Mikho]

I know its been a couple years since I've raced but wonder about this question.

What is the optimal temp the tire should be compared to the track surface on 33x10.5w M/T tires? Does this depend on different tracks, temps, weight or any other variable? or is there a set temp to shoot for

[Wheelycool]

Yes - Dan Fletcher is awsome!
We are very proud to have him as a Team M/T member.

I'm sure he will adjust his schedule to maximize his championship chase.

Thanks Kyle!

Good question Monte. The rule of thumb is typically within 10 degrees of the track temp. With that being said, as ambient temps go up, the burnouts can get shorter. This is due to the ambient tire temp already being warmer. On the flip side, as the tracks get cooler, the burnouts can get longer.

Hope this helps.

Hey guys thanks for stopping at the Bullet. My question is about air pressure in the drag radials.........do you think there will be much difference in the pressure from my 325s to the 275s I will be running a bunch this year? Have you seen a trend one way or another?

[ford101mustang]

Im getting ready to head to the dyno. I was wondering how much my tire's will grow at say 150-160MPH? There 28x10.5 on a 10" wheel. I just wanted to see if i need to trim the wheel wells any more i have about 3/4" clearance right now.

Thanks
Brandon

[white mule]

How about a 31x13.5x15 ET Street?? Hoosier has 'em, but I don't really wanna run Hoosiers for my class tire size.

[jboehm]

Do I need to run more pressure? This is a 28x11.5 et street @12 psi cold.

[camaroguy327]

copied from another thread.

Do you all have a 215r60 or 215r50 ( 15"wheel) drag radial that will handle a 5100lb pickup or do I need to find a way to lighten the truck to make it fit the tires limits? Nothing radical just a stock 350 chevy with about oh 390 hp. I just want to drive it to the track and not have to change to slicks for a test and tune then have to change it back to drive it home.

[Jason Moulton]

anything rated over 130 MPH?

Nothing over an "H" rated or 130 MPH. However, it is important to know speed ratings are not relative to dragstrip speeds.

Thanks,

Jason Moulton

[Tireguru]

It's gonna be close, we'd suggest an Inch Clearance.

[Wheelycool]

Hey Mark!

That's a great question...
I think you would need to run the same pressure on the small tire as the big one to start. My inclination is to try 1 or 2 pounds higher based on the reduced contact patch with the same weight.
As always, I would try to run them with as much air pressure as possible based on the conditions.

PS - I really enjoyed your web site!
Carl

[Jesse Lambert]

What tire pressure do you recomend for a 315 radial on a 15x10 rim? I have heard and tried anything from 13-18 lbs

[Monty Mikho]

Good question Monte. The rule of thumb is typically within 10 degrees of the track temp. With that being said, as ambient temps go up, the burnouts can get shorter. This is due to the ambient tire temp already being warmer. On the flip side, as the tracks get cooler, the burnouts can get longer.

Hope this helps.

Jason Moulton

Is there an adjustment to tire pressure that needs to be made when temps go up or down? something like a ratio or such? Reason I ask is I never had anyone read tire to track temp and made adjustments accordingly to data from the data logger. I logged in a book different tracks, temps, surface grade, etc etc but nothing was concrete that I could find. I often made tire pressure adjustments and made a test pass to see. Didn't know if there is a better way to do this other than that. Sorry for the silly questions

[Jason Moulton]

How about a 31x13.5x15 ET Street?? Hoosier has 'em, but I don't really wanna run Hoosiers for my class tire size.

Nothing on the drawing board. We have the 30X13.50-15LT and 31X14.50-15LT.

[Monty Mikho]

1 last question and I will leave you guys alone..

To tube or not to tube. That is the question :p

[Novi357]

Thanks for a great product. I actually got my 9 second license on a set of 17 inch m/t tires and have run 8.87 on a 295/45-17 m/t drag radial.

Thanks man!!! Thats what i was thinking. I guess i will chop it back another 1/2 inch to be safe.

Thanks Carl for the reply and your support! I didn't think about a smaller tire needing to support the same weight will need more pressure. I will keep that in mind.
Did you guys get the calendars?

[gdsims231]

We have a brand new track and are going to host wwhat we hope to be major event a couple of times a month. We are also hosting the ORSCA season opener and world final. we are looking for support from MT. I have e-mailed a couple of people at MT only to get no response. What we are doing seems to be in line with other things you have recently supported. i would just like a response.

thank you Greg Sims Promotions and marketig

Nothing on the drawing board. We have the 30X13.50-15LT and 31X14.50-15LT.

Jason Moulton

Thanks, I will be running the 30's.

[Wheelycool]

Man... cool shot - I would say by only looking at this picture that you should be able to run more pressure. The distortion shown cannot be beneficial. I would also try a set of tubes in this application. They really help the tire retain the correct shape. As always, I encourage everyone to run as much air pressure possible dictated by the track conditions. The 60 ft times will be the absolute deciding factor.
Thanks,
Carl

[Wheelycool]

Yes sir!

I don't get a chance to race as much as I'd like but when I do I like
to get the best 60ft possible.

Can 28x10.5 Slicks be stored without losing their "Stuff" ?
if so what is the best storage practice?
How long will they last (Stoage wise not wear)


Thanks

We've never seen a relationship between air pressure and ambient temperatures. Air pressure can be a "tuning" device in small increments, but it is more related to track conditions.

Thanks for the question.

Has MT thought about producing a 29.5 x 10.5 radial slick, and if not, why??????

SWEET! Hope to see you guys at Bowling Green for the NMCA race if you are attending. Have a good night.

[Tireguru]

205/50R15 PT#3750Ror 225/50R15 Pt#3751R ET Street Radial is the closest. They are rated at a much lower Load Rating then 5100lbs!, but for Short Blast 1/8 or 1/4 mile, they would be OK.

[Wheelycool]

Monty,

We have seen some improvements with the use of tubes but I would suggest some testing to see if your application will benefit or not.

Thanks for your question!
Carl

[Jason Moulton]

What tire pressure do you recomend for a 315 radial on a 15x10 rim? I have heard and tried anything from 13-18 lbs

Over the years we've seen a closer range of 14-16 PSI. Most people recently are 14-15. I would try 14, then jump to 15. That should tell you which is the better way to go. Then you can "tweak" from there.

Thanks,

Jason Moulton

[kfickler]

Thank you Carl. Hi Ken and Jason.

I have noticed a trend toward racers not using rim screws, even with 7 and 8 second big tire cars. What are your thoughts on rim screws for big tire and little tire cars. My opinion is that we can't have too many, but as you guys know I'm kinda old school...

M/T recommends that tires be stored in a cool dry place out of direct sunlight and not on the ground (off the car). We generally state that tires will retain maximum performance in the two year range. I will let you know a secret though...
Bill Glidden won the PSCA race in Vegas on 5 year old tires.

[Jason Moulton]

Has MT thought about producing a 29.5 x 10.5 radial slick, and if not, why??????

Here is my reply based on a similiar question asked earlier today. Thanks for asking!

That is a good question. The current radial slicks are designed for Stock, Super Stock, and Comp Eliminator categories.

I'll say this, the great thing about a radial - it doesn't absorb a lot of power. The bad thing - it doesn't absorb a lot of power. It's important in the 10.5 market to control the amount of "hit" the car gives in order to get it down the track. Radials are not as "forgiving" when it comes to tuneups and track conditions. In other words the tuning window is not as big. Running on 10.5 tires, you are already limited.

With all that being said, we've come a long way in the past few years with radials. With our development going on, and BG's help, we learn every day.:wink:

Thanks,

Jason Moulton

[gdsims231]

I think we both know the reason for the question. Wouldn't you agree that the reason the radial is as fast if not faster on a GREAT track is because of the sidewall? You already have an s model in the 10.5 is there no way we could get a SS(super stiff) for those great tracks?

[Jason Moulton]

Anyone going to ADRL / Houston this Weekend?? Carl, Jason and I will be there!!!

[Chevelle Rob]

the tires on my car are 8+ years old and have been stored in the garage on jackstands the whole time. I have about 70 runs on them and a few street miles (very few)

in this video on the last run you can clearly hear the tires "squeeking" on the gear changes for an extended period.

http://video.streetlegaltv.com/video/8268

I couldnt feel anything in the car though, could the tires really be slipping that long ?? it appears to be hooking fine on the launch now.

I have to say for the tires to be this old and still get down the track at all is a testament to a great product.

Thanks

[Wheelycool]

Kyle
Well Kyle - here's the old school reasoning...
Wheel screws were originally installed to keep the tire in place and avoid tube failures. Since many found that cars could go faster with reduced unsprung weight (no tubes) so it then became more standard to remove the tubes but the wheel screws were retained. Then, we started watching the effect on the performance based on how many screws were installed. At some point in time the wheels improved especially in the area of the saftey bead. This made it safe to run tires without screws. So to summarize, I think that screws can be beneficial to a point. Many applications in today's enviornment can perform well with or without them. At a certain point Bead-locks come into the picture. Did I help or confuse the issue???
Thanks,
carl

Certainly the radial has the potential. However, there is more to it than meets the eye. Making it work consistently so you can tune to it is the tricky part. You never know what the future holds is all I can say at this point.

In regards to the sidewall stiffness, that is something that can bite you if you go too far, especially on the great racetracks. That's something we have figured out over the years.

Thanks,

Jason Moulton

Hey Rob!

In this case the noise that I could hear was quite normal. New or old they can all make the screeching noise. At 8 years old I would think that you might see some peformance improvement with new tires on the car.

In 8 years the technolgy has improved and there may be a better tire for your car.

Let me know if I can help you with that selection.

Thanks,
Carl

How much tire spin (in revolutions) do you want on the launch with a 29.5x10.5S in a 3300 lb small block nitrous application?

[Wheelycool]

How much tire spin (in revolutions) do you want on the launch with a 29.5x10.5S in a 3300 lb small block nitrous application?

Richard,
In the ideal scenario you would want no tire spin, but that is not realistic. Ultimatley the only real gauge is performance. For example, a Super Stock car with Drag Radial slicks will hook and go one to one with the track - every time! The extreme example is the NHRA Pro-Stock car. If you dead hook the car it would literally stop the engine! So, you need to watch the 60ft times and adjust your package accordingly. I don't really know too many people that can watch the tires and count revolutions anyway!

Thanks for your question,
Carl

put some shoepolish on the sidewall and film it, ask me how I know.

Thanks for the response Carl. I suppose there is no real answer to my question then... just keep trying different things and watching the incrementals??

[dpharris]

any info on when the 325 radials will be available

[bags50lx]

Is there a chance of making a 28"/29" tall drag radial for a 17" rim.

[Wheelycool]

Thanks for the response Carl. I suppose there is no real answer to my question then... just keep trying different things and watching the incrementals??

Yes Richard - you get the point...
You are correct in saying that there is no real answer because the variables are so many. Just let the car tell you what it wants...
It's all there - just reflect on the data and you will figure it out.

Thanks again,
Carl

[Wheelycool]

Is there a chance of making a 28"/29" tall drag radial for a 17" rim.

Anything is possible, but there needs to be a significant demand for a specific tire size before we can invest in the development and associated costs. You know how it is today...
We must have a good business case before we initiate any new products!

Thanks for your question!
