Several weeks ago, had my first flat on my tubed, yet tubeless Ready 27.5x3" rims...
Took to LBS and told them to go tubeless...they did. 50 bucks.
Apparently, I way-over-inflated (I commute mostly road) and while biking home, heard a HUGE explosion.
Scared the crap outta me. Sounded like a gunshot.
Completely blow off my back tire off the wheel...carried my bike home in shame.
Back to LBS for new Tire...60 bucks...when they installed the tire, they warned that spokes had been damaged and could not be effectively tighened w/o further damage...
Took it home, but soon became bike felt unridable. - RIm was out of tune and very wobbily....apparently I damaged the wheel during this explosion also.
Back to LBS for new back wheel....$420 bucks...for a 27.5"x2.75"....it's adding up.
I have my bike back now...seems to be riding ok...the smaller diameter wheel in the back is a bit odd, but doable.
Have now rode for a week and could really feel the tires drag on asphalt...knew I needed to inflate.
Inflated this morning to 31psi front (still tubed) and 29psi back(tubelss)...(tire sidewall reads 17-35psi)
MUCH MUCH BETTER...but I still am waiting for my back, tubeless tire to explode again...think I have PTSD about it.
Anyway, my questions are...can you inflate and run tubeless tires at the upper extreme of their rating???
How often should one be checking and re-inflating tires?
Could I really have damaged the wheel with over-inflation??
Not diameter, your new wheel is narrower so it's width. I highly doubt you're able to feel a .25" difference between the new wheel and the old one.
Yes, you can definitely damage a wheel by blowing the tire off. That's a huge volume of air. I'm guessing this is a knobby/dirt tire. Do NOT overinflate it in an effort to make it roll better on pavement. I wouldn't go higher than 30psi.
