ive bought and sold alot of cars. driven some real beaters in my life. one thing ive learned is that you can control a blown tyre without much effort.
one time i was down in the fla keys and noticed my tyre was seperating at the ply. it didnt look bad, the spare was flat, so i drove home at 65mph. it was 150 miles home by the way. about 20 miles from home the front end of my car drops down 2 inches with a thump and i see a big black wad of tread go flying off in the direction of the ditch. what happened was that my tyre lost all its tread. but the inner carcass still held air. im glad i took the slower side roads with no traffic. this wasnt technically a "blow out" but the tyre balloned up like a well, baloon. it probably gained 20% of its normal size. long story short i end up driving home 20 miles on that tyre since the spare of this new car was flat. i made it home fine and got a couple new tyres the next day. the blown tyre was still holding air the next day.
had a tire blow out on my motorcycle one time. the front got low from a nail and i knew it was comming because on a motorcycle you can "feel" when a tyre is low. the bike gets all squishy. so i turned around and headed for home. i didnt make it and the tyre started seperating and flapping. you know its bad when the inner tube and rim strip get ripped off and go flying. i just did 15mph and got home ok. the rim survived fine. tyre and tube were shot.
hmm, i once had an old mercedes 300 turbo diesel that had tyres probably 15 years old on it. the car hadnt ran in a while and i spent a weekend on it getting it running. i was so excited that i took it for a spin around the neighbourhood. one of the front tyres tread ripped off. the tyre still held air and i limped back home on the carcass. but the entire tread was gone from 1 sidewall to the next. just like the other car.
i had a few blow on my mazda protege. the construction site i worked at was notorious for eating up tyres. i think it was the fact of running over 6 inch rocks and concrete chunks that damages tyres. anyways i had quite a few ply seperations and blows on that car. normally it would start thumping and get progressivly louder untill it actually went. if it was in the front end you would feel the steering wheel jerk to one side once per revolution. also the car would swag left and right. if it was in the rear end the car would swag left and right, but no jerking on the steering wheel.
ive been through a couple trailer blowouts too. they are the best of the blowouts because you hardly even notice it except for the damage it does to the fenders and wiring. but you dont "feel" it from the car.
really, i have never been in a situation where a blown out tyre has caused me to swerve or lose control. i just let off the throttle and pull over to the side. no big deal.
heck when i was rally crossing, the surface of the track was crushed coral. it ATE up tyres. in probably 30 minutes of racing i could burn through half the tread on my brand new tyres. i got a flat at the start of one race and had to finish the race on that same flat. you know what i still didnt do too badly.
the only time i really had a problem was with my dads 64 impala. he had this sweet impala with a 409 cid engine. i was driving it home one time from a car show following him in his truck. the car started thumping and like 1 second later the rear end dropped and sparks were flying and i couldnt control the cars steering. the brakes even went out. i couldnt hold it on the road and was veering into oncomming traffic so i steer the car sharply to the right and went off into the woods at 55mph. i ended up flipping the car 3 times, broke a 6 inch tree with the engine block and totaled the car. the axle on the right side was defective. it broke in half and the hub, drum, wheel and tyre went off into the woods never to be seen again. seriously, we never found it. but the axle has cracking where it broke and rust marks inside the cracks. since there was rust we figured it wasnt a new problem and had been there for some time. thats not technically a blowout, but it was sure scary. thats really the only time i couldnt handle it. when the tyre wheel drum and hub broke off, they snagged a brakeline on the car so it couldnt build hydraulic pressure when i hit the brakes. it just pumped fluid out through the broken line.
