Tires that resist freezing :annoyed:

[--weezl--]

Haha yea I went home for christmas once with 44" bias tsl swampers and the drive is 8 hrs. It was -64 below when I parked at my folks and the next morning good luck, had to drive the back roads and trails for half an hour before getting near a real road.

jesus! what were you driving when you did this?

just goes back to the air pressure thing ibrought up, Im thinkin before the cold hit (or after) you never checked your pressure to make sure they were up to snuff.

If its that cold, your tires heat up a lot when running... Which means the air inside of them expands. A lot. If you aired up your tire when its cold you'll blow a bead by the time you get to full running temperatures...
And when you air it up at running temperature, once you park it, the air compresses, and bam. D-shaped tire in the morning.

 

[--weezl--]

so you're saying that if i fill my tires to 35psi, with the tires cold when it's -30, then drive down the highway, the heat from my tires turning are going to bump the pressure up past the, most likely 3:1 safety factor, minimum, and blow the tire out?

what if i don't let the air out of my tires when we go into summer? i mean, calgary gets to -40 in the winter, and 35 in the summer is not uncommon, the change of 75* in 6 months isn't going to cause this though?

how about when calgary has a chinook, which normally causes temperatures to change by 10 degrees per hour, and again, not uncommon for it to change by 15-20 degrees... would that cause my tires to pop?

Yeah that would only happen if you filled the tire to max psi in like -50 degree weather to begin with... then driving to california or something. I've filled up tires to 35 in -40 and drove for 6 hours then parked it in a heated garage and the pressure was only up to 45 the next day.

I didn't say there was any guarantee of blowing out or anything, but you do run the risk. Plus I said you would pop it off the bead, thats all..

And dont lie to me, 35 is stupid-hot in Calgary, even for summertime. lol

The simple physics of it is air expands as it heats up.
If you dont beleive it, I got a simple test for you... take a balloon. Blow it up. Now put it out side. It will be significantly deflated in a while once that air inside the balloon has decreased from your body temperature to the -20 or whatever ridiculous temperatures you have in Cowtown today.

it's 3 in calgary today... and it's been in the mid 30's every summer i've been here since i moved from vancouver...

how do you blow a bead without blowing a tire, from excess pressure? the difference about blowing up a balloon inside and putting it outside is the fact that the average person can only blow 2.5psi, and a balloon does not take that much pressure before popping... so your balloon test is irrelevant...

jesus! what were you driving when you did this?

It was a sweet 1972 gmc jimmy I built.

i worked for a tire shop out in fairbanks alaska was negative -36 currently have 30 inch mickey thompsens on my bronco 2 and they dont get flat but in the tire shop we would hear what your talking about alot look on the side wall and buy a tire that has an A for temperature rating ones with a winter snowflake like goodyear wrangler silent aromors do excellent

Its not irrelevant at all. It still is a real-world scenario that illustrates the fact that air compresses in cold temperatures, and expands in warmer ones. Some people have a better time understanding principles like that when they can relate it to something they have experienced or seen.

And its 3 today? Damn. Thats a toasty January day for you guys... lol

it was actually 5* when i left for work at 10pm... quite nice indeed, didn't need gloves or even a jacket to fill the tank! though i did use an entire reservoir of washer fluid on the way here... god damn mud!

your right, the principals still apply, but the rate of expansion decreases with each additional psi, if you heat 1psi by an amount enough to make it double in volume, there will be a point where it will compress to 2psi, however, if you ramp it up to say 10psi start, and you heat it from the same start temp, it's not going to double in psi, by the same increase in tempature

-30F good god
You need to move somewhere warmer. It got down to a staggering 40F here last night, so cold I had to put long pants on.

I'd suggest winter tires... I'm running Bridgestone Blizzak DMV-1's and they are exceptional winter tires.

Cost wise winter tires are really cheap compared to all terrain tires and overall as you save wear on the all terrains it doesn't cost as much as some think it might to have the best tire for the season year round. I paid $112 a tire for the Blizzaks in 245/75-16... I've never seen good all terrains at the kind of price.

my boggers were almost like the cartoons, u know when there car has a flat but the flat part goes all the way around lol sucked ass, but gawd those tires were a beast offroad at about 6psi

Well,
As for living in -30Fto -60F winter temps I only got a small say in that. Uncle Sam said go and I said YES SIR! Yeah I am going to get winter tires as I don't want to kill the pricier all terrains I have been saving up for. Unfortunately I waited until winter was full on to think more about this and yes indeed the Alaska stores stock to the roof and beyond and yes they sell most of them for the folks who think ahead and get them and now there are like 5 tires left in my area and they are all different makes..... I'm sure I can find some though. Gotta do that soon, perhaps when the Chinook winds hit and we get to something well north of 0 for a couple days! Thanks all for info and advice. I very much apprecite it. I took an unanticiapted slide toward a deep ditch the other day and let's just say it got my attention!
