The tire has
ABSOBLOODYLUTELY HAD IT!! It doesn't matter how good it looks from the outside, take the tire off the rim & inspect the inside - almost certainly, it's gonna be visibly shredded, & even if it isn't visibly shredded, after riding on it flat for anything more than about 30 yards or so, it certainly will have torn/damaged the sidewall plies embedded inside the rubber, making the tire a throw-away &
well beyond JUST dangerously unsafe!! :yikes: nojoke :yikes:
On a new tire, if you look inside them you can usually see the inside skin that looks a slightly different colour than the outside rubber,
THAT skin is the bit that keeps the air in & allows the tire to hold the load off the road surface at the same time as letting the outside bits get up to their operating temperature - any damage to that means the tire is compromised! Most reasonable quality tires (probably not Kendas tho!) can easily handle running at low pressures for a fair while, just so long as the rim isn't pinching tire rubber between it & the road - in fact I've purposefully run tires at less than 10 psi for over 2000 miles (was
paid to do so actually - testing, at slow speeds of course!) Buuut, unless the tires you are on are specially designed Run Flat Tires, they can usually only last maybe a few 10's of metres/yards of running absolutely flat, which effectively means having the rim pressing all the load onto their insides when the tire's flat; so maybe they'll survive running 20-30metres MAX; but beyond that, then internal damage, visible or not, is pretty much guaranteed!! So beyond that sort of distance, the tire's definitely toast, & an inside inspection will reveal that very quickly!! So get your tire off the rim & have a look - I'm reasonably sure you'll be horrified at the damage that
IS going to be there, & even more horrified that you ever even considered riding anywhere on that after your slow trip home!! :shocked:
While the tire is off the rim, check the rim carefully for any gouges or cracks on the raised bead sealing edge - if there are any sharp gouges or visible cracks, the rim will also be a throw away, but I doubt riding carefully & slowly while you actually had rubber between the rim & the road will have killed it - but you still
MUST CHECK!! Running an alloy rim on the road directly (with no rubber between it & road surface)
WILL damage it, so you need to check very carefully!! Steel rims will probably survive a touch or two, & you can usually hammer out any dents & file off any sharp edges/nicks; but you can't really safely hammer an alloy rim back into shape & visible cracks mean the invisible stuff makes the rim
VERY unsafe!! That said, modern (quality) alloy rims are stronger than steel rims, & some can even be re-rolled back into shape if deformed, but flexing & bending them anywhere can compromise the structure & create weak areas, it takes specialist gear & skills, & should involve X-rays afterwards to confirm they are up to the stresses of riding safely! :sour:
Still, to sum it all up,
your Tire is DEFINITELY TOAST, throw it away & get a new one!! The rim
should be OK, unless the raised edge has touched the ground directly (without rubber between it & the road surface) in which case you need to very carefully inspect it for damage. If you
know it touched the road surface with the alloy rim anywhere, or if can see
any damage on the alloy rim, then it needs specialist inspection before being deemed 'safe', & that just might be more expensive than replacing both the front alloys, particularly if you go with a/mkt rims anyway!! :dontknow:
Don't be too hard on yourself tho, the longer you ride (or live for that matter :lecturef_smilie

the more likely you will do some dumb things - the real trick you want to take from all this is to learn to recognise those dumb things & learn from those dumb things before you make them worse by doing something even dumber!! :shocked: Oh, hang on, you've already recognised & learnt about dumb step one followed by dumber step two, haven't you!!

It's just some of us slow learners who managed to keep going for a while!! I can tell you from experience that having a tire
AND RIM disintegrate at speed underneath you is
NOT FUN!! And it's made soooo much more NOT FUN when you
know you shoulda read the writing on the wall (& the chips/cracks in the rim) & thrown it away back when you changed out that tire you'd shredded earlier!!

pps: Like I said, I might be a slow learner, but once I've learnt a lesson, it sticks! :2thumbs:
