The few times I've had to change a flat I've either been near my destination, in which case I just change the tire in the parking lot, or I just drive until I find a spot where I can pull completely off the road.
I'd rather wear down my rims a little than risk getting hit.
That's what happened to me, because the leak was so slow that I didn't notice the flat until we had been running on it for a while.
It isn't the rims you have to worry about. When the tire is deflated,
the rims grind down the sidewalls of the tire. This will ruin an
otherwise repairable tire.
It's worse than that. All that friction of the cars weight creates a lot of heat, eventually, the tire will catch fire.
I've seen a few of these where a guy was stuck with a flat tire and decided to drive it anyway.
And then his car catches fire.
They don't tell you this, but it's one of those obvious things after your car is heavily charred.
Ford (I know this, because I almost did it myself, I fell asleep driving home having not slept for about 40 hours and hit a curb and blew out my tire (nothink like getting woken up by having your head smash against the roof of your car) and I was soooooooooo tired I didn't want to change it or walk the mile home, so I drove it home really really slowly, it was smoking by the time I got home. I'm damn lucky it didn't catch fire. I should have just slept in my car, aaaah the good old days.) ][
the skis) tear the shit out of the asphalt... and it's hell on the track...
...not to mention snowmobiles depend on snow for lubrication (track on hyfax)
and cooling (track kicks snow up on the tunnel, where the heat exchanger is).
Good point about heat build-up. Didn't think of that.
I'm trying to remember, but I don't think I've ever tried to get a flat tire repaired. Every time I've gotten a flat, the tire couldn't be repaired, so I ended up having to buy new ones.
I'm not sure I'd want to drive on a repaired tire, anyways. I drive a little on the hard side, and I don't want the possibility of a tire patch coming loose going around a corner. This is just me, though, so, pardon the pun, but your mileage may vary. :)
That episode with the curb yielded a 4 in gash in the sidewall. no fixing that.
if you get a screw or nail or something small through the tread side of the tire not too close to the sidewall, the plugs they fix them with work fine. I've done plenty of sideways on tires with puncture fixes like that with no problems.
I had a flat several years ago while driving fast... when I stopped on the spare track, I burnt my fingers touching the flat tire... luckily the highway had an open exit for maintainance just where i stopped, so i could escape.
but... that tire was all wasted. it had tiny gum nibbles roaming through the weel...
there's something in my family about being told to run when the tire was smoking. (as in, oh @$#@ the tire's smoking. When I pull over, everyone get out and RUN)
and then the tire exploded.
I donno. maybe it burst into flame
or made a large popping sound for some other reason.
On TDIclub, I learned to stay away from K&N air filters. At least I can say that.
