Actually, you should have done the opposite and added a few more pounds of pressure to the tires before making the high speed run.
My line of thought:
P1VconstantT1 = P2VconstantT2
Therefore, to keep volume constant despite increased temperature, you should have to reduce pressure.
Here is the explanation.

Thanks!
They’re stupid and pointless. Dying because you smacked into the ground while you have more important things to live for is not a risk worth taking.
You and I see risk differently. Fact is, a LOT of people ride motorcycles over 80 mph on a fairly regular basis without a helmet and are not the worse for wear. To be clear, I would not do it.
But I remember the first time I ever rode my own bike. I bought a used 1983 Honda Magna V45 in 1997. I was doing 50 mph on I-405 in Bellevue on a nice sunny day and I thought I was going to kill myself. Within a few weeks I was topping off the speedometer on a regular basis (85mph).
No, I was not suicidal. I understood the risk. Over my riding career since then I’ve had cars on the freeway try to occupy my space on numerous occasions. There was never really a risk because I assumed I was invisible and always had an escape route.
I’ve been hit by cars three times while bicycle commuting, but I never went down. I just tore up the side of the car and kept going (people going the same direction as me deciding to take a right).
There is risk of death and injury whenever one works with machinery and/or speed. When you work at the place where the ones that are hurt end up going, you end up with a biased perception of the danger. My nurse sister-in-law calls motorcycle riders “organ donors”, yet I’ve been around a lot of bikers, both as a biker myself and in a band that plays at a lot of biker events. I’ve never knew one that actually donated an organ, though I have beed aware of “fallen friends” that have been. Not that many, though.
And my son has been to two funerals for bike messenger friends in downtown Seattle that were killed in mishaps with cars running red lights.
Life is risk - and very short indeed. Eternity is, well, eternal, if you are the Lord’s.

Too many Americans die of heart failure and adult onset diabetes while watching the adventures of others on TV.
I’m a doer, not a watcher. I was able to give up TV in 1997 because I don’t watch sports. I DO sports. I’m 59 and STILL bike and mountain bike. Both involve risk.
To give you an example of how I DO recognise risk, I stopped bicycle commuting about 4 years ago because texting has made it “always 2:00 Saturday morning”. Being on the road during the commute on a bicycle on a daily bassis is no longer worth the risk for me. I see it as a form of russian roulette. It’s because I’ve seen WAY too many people randomly veer off the road right into where I would have been if fate had not been on my side.
I need to add one thing: Not all riders and drivers are created equal. The lions share of motorcycle fatalities and injuries are young guys on 600 cc crotch rockets. And it isn’t just their age that causes it. Fact is, a lot of people do not have the hand-eye coordination and spacial reasoning ability to handle a bike safely. Older people know their limitations more than young people do. It is my personal forte. It is for a couple of other riders I know personally.
I’ve also seen guys on bikes that have no business riding. I watched a guy in front of me trying to adjust his helmet while riding around a corner and he went wide, straight into the side of a boat being pulled by a large truck. He had no business doing that on a corner. He had no business riding a bike.
Bikes are kind of a darwinian gene pool cleanser.
Ruh-roh. Same as me. After 3, I gave up. The last time I did a summersault and landed on my feet, landing without a scratch. Why I didn't give up after the first crash, I don't know...

It’s why I consider freeways pretty safe. Everyone is going the same direction and roughly the same speed.
The one time I was worried was coming through the international district of Seattle from the east at about 40 mph downhill and a woman going the opposite direction decided to make a left right in front of me. Again, having anticipated that she might do that I was able to go around her - in front of her. ;-)
But that one did get the adrenalyn going. I’ve put tens of thousands of miles on bicycles. The only time I ever went down was in summer of 1966 when I was jumping dirt mounds on my paperboy special. I’ve seen plenty of other guys break bones though - especially in pace lines gone wrong.
140 in my 944S, but that was at Watkins Glen.

On a Virginia to Massachusetts trip, we passed 32 motorcycles. Actually, 30 passed us, at high rates of speed, as we travelled at 70 mph.
Of those, 28 were driving recklessly, weaving in traffic. Most were kids on Japanese bikes.
So my conclusion is that motorcycle riding isn’t inherently dangerous. The drivers are the problem.

I put it this way:
There are two things a man should not do until he is 35 years of age:
1. Buy a motorcycle
2. Get married.
Not just Fords. It affects any solid front axle, quite a bit more likely with coil springs than leafs, as the leafs tend to hold the side-to-side motion in check better.
It can be something as mundane as worn out tires (my issue on my '98 Jeep Cherokee XJ), or any of a combination of things. Chrysler just came out and addressed it in fairly current models of the Wrangler.
My wife and I witnessed it on a newer Wrangler as we were travelling through Salt Lake City a few weeks back. My wife saw it first. I told her that was what my Cherokee was doing before I fixed it. It's violent, and if you aren't prepared for it, can cause a bad accident. Even if you are prepared for it, you can't stop it, you're only along for the ride. It's a shorts-changer, for certain.
The average mountain biking is not as risky as stupid things like bungee and sky dives and rock climbs. Sorry, the risk level and/or the costs are too great for something of no real worth.. How would you like to be the person who goes through life explaining his dad died when he smacked into the ground from a short cord and grew up without him? I’d feel just about resentful.
Not so sure, the '67 Galaxie would snuggle down to the road over 120...sure 'floated' before that, from about 90 to 115, but afterwards, there was some sort of ground effect that kept it down.
No, it’s physics. 2 wheel set is less stable than 4. Everything else being the same, the motorcycle is more dangerous.

I do not live my life in fear. I DO consider the risk/reward formula (it’s actually part of my job) and proceed accordingly.
So far, so good.
