tires and speed ratings

[BlueSVT]

did motortrend do it on dirt? It was about 150 feet on my map app from the last undulation (big speed bump) to the stop sign, I was doing between 65 and 70 and didn't start braking until after my back tires left the undulation, that would bring it down to 130 feet or less to the stop sign, and I stopped 5 feet before it, lets say I was in the middle of my speed estimate (65 was how fast I was going the last time I looked at the speedometer before I went over the undulations and I was still accelerating through them, so I could've been going even faster than 70, but I don't think I was), that would be 67-0 in 115-125 feet, not bad for a 3 ton truck, like they say, car magazines vs. real world, there can be a big difference



I love the autobahn so much, as well as the nurburgring, most fun I've ever had, you sir live in the best driving country in the universe

No, it's not on dirt, on pavement! The supercab faired a bit better at 133-feet. This sounds about right to me.

My STI was a 3400lb car with Brembo high performance brakes all around, and 106 is ASTONISHING for that car, same as a Z06 with Brembo 6-piston calipers.

Now take a 6500-lb truck with regular 2-piston calipers and standard brake pads... You're not going to get anywhere CLOSE to the 100 foot mark.

Hahaha yeah most people don't think about the brakes lol. The first mob on the Boss Hoss was 4 pot Brembos and steel lines!!!! Who cares how fast you can go if you can't haul it down. Put the ss brahe lines on the Haysbusa as well makes a big difference. .

Been around 200 more times than I can remember on that beast but alwsys for short runs on open divided highway with no cars on either side of the run. Helps keep the popo from getting you as well. The Raptor is not built for high speed running no matter what you may have read. Way too many other components to fail. If

It makes me sad to see an accident looking for a place to happen. And the comment about older is not smarter, well that's a young kids answer because he does not know. Of course we are all invested in you as we share the road and if you think were not you really are less mature than your age of 21 would indicate. I can tell you by your answers given you think your in control and lack the understanding of speed, weight and distance to really know how little control you really have. Hopefully you live to June 1st go to our outing and a couple old farts between 30-50 will show you a thing or two... You lack the real world experience to make comments of you being all knowing..

Also I don't think its been mentioned here yet but isn't the driveshaft only rates for 110mph.....

Yes you are so correct and I did above in the "other components"---but you know some people are just ignorant and muddle through life.. Better for them to be lucky than good lol...

Some people think that this is a race vehicle lol as it comes off the line at Ford...

This is one of the functions of a forum such as FRF. Cleve is not an irresponsible youth as some posts may insinuate. Young, yes.
I am really excited that this meetup on June 1st is happening. Transfer of knowledge will be great. And this can lead to the wisdom needed. BTW, cleave was/is instrumental in getting this going. The exuberance of youth in Cleave & IHaveGas is what got it organized.
I am really looking forward to meeting more experienced drivers to learn from. I am outside the stated definition of "old", on the high side. But I ain't dead yet. Hopefully I can contribute something.
This is gonna be good!!

I am really excited about this meet also, but I think my wife is more excited than I am.. I don't mean any disrespect to any of our youthful drivers, I was one, once. But I know it is simply irresponsible to drive one of these trucks on public streets at over 100 MPH.. It will be Ihavgas final meet before he departs our area so it is also a going away for him.. Having buried a few friends from mistakes witnessing first hand the pain caused by irresponsible driving, riding motorcycles and flying it is really important to understand the risk reward of driving at whatever speed you travel..

Here is a quick formula to help understand how far it takes and how dangerous it is....
All drivers take a fraction of a second to perceive a hazard, and a fraction of a second to react before putting on the
brakes. This time translates into perception and reaction distance—the distance your vehicle will travel in the time it
takes you to perceive the hazard and to move your foot from the accelerator to the brake pedal. To figure your perception
and reaction distance in feet, take the first digit of your speed, add it to the total speed and double it.
Speed + First Digit = Perception/Reaction Distance
20 mph + 2 = 22 feet x 2 = 44 feet
In other words, at 20 miles per hour, your vehicle will travel 44 feet in the time it takes you to see a hazard and
move your foot from the accelerator to the brake pedal.
The faster you’re going, the further your vehicle will travel before you can hit the brakes.
Speed + First Digit = Perception/Reaction Distance
55 mph + 5 = 60 feet x 2 = 120 feet
65 mph + 6 = 71 feet x 2 = 142 feet
Braking distance is also determined by speed. Here are braking distances for some speeds for a passenger car
with well-maintained brakes on flat pavement in dry weather:
At… Braking distance is…
20 mph 18 to 22 feet
55 mph 192 to 224 feet
65 mph 267 to 316 feet
Now we can calculate the stopping distance for these speeds:
At… Perception/
+
Braking
=
Stopping
Reaction Distance Distance Distance
20 mph 44 feet + 18 to 22 feet = 62 to 66 feet
55 mph 120 feet + 192 to 224 feet = 312 to 344 feet
65 mph 142 feet + 267 to 316 feet = 404 to 458 feet
It’s easy to see that stopping distance is very much greater at high speeds than at low speeds. The faster you are
going, the greater the distance you must allow between you and the car in front of you for safety. Wet conditions
can double the stopping distance; icy conditions can make it ten times higher.

That's a great way to look at it. Thanks for posting it.
I was a very irresponsible youth and it is thru several Divine interventions that I, and my friends, are around today.
With the lose of the family as we use to know, we need these little meetups to to pass on things we should have gotten from uncles, grandparents etc.

first, where do you guys assume I was doing 100 mph for extended periods of time, this was on I-80 going through nevada, I only saw another vehicle every 10-20 minutes at most, that's at most 18 cars over the span of 3 hours, and I could see for miles on either side of the freeway and miles ahead, second, I wasn't refering to all drivers age 30-50, in my post I said "who have become complacent and no longer pay attention to the road", and that's not the old age group, that's my dad talking through me, you're not old until you're 70, my dad says he's old every day and that's been since his early 50s, it's been working on me for a while and starting to creep into my speech as well, I'm sorry, and lastly, the braking distance I gave was from real life, and it did happen, so I don't know what to say if all you can accept is numbers from a magazine

I'm not trying to start any fights, but I don't take kindly to people calling me an idiot when they never knew me just because I'm young, this was a thread for those of us who want to find higher speed rating tires, I know there are people on this forum who have gone faster than I plan on going in this truck, and they don't do this kind of research before hand to find tires and driveshafts that can handle those speeds, I'm sorry I started a thread on safety and all you guys can see is me trying to be unsafe

We all just need to get to know each other. It's easy to offend and be offended on a forum.
