rim beads worn through after 2 rides

[chriss2.0]

HI! my name is christian , iv been looking all over for an answer to a most perplexing problem.

i have just bought a new bike (sirocco 2) and i have all terrain tires. i have ridden a total of about 200miles ,
on one ride about 20 miles from home i got a bulge, so i rode back to fix it, and when i deflated it, i could see the bare threads of the beading. (the manufacturer is sending new one

so i fixed the tire and decided to use it for light use. but shortly after, BANG! it had worn completely thru.

on closer inspection there are signs of the same wear all around the tire, and the inside of the rim had become rough. so to be safe i checked the front too. same thing!

so my question is, what could be causing this?

i dont want to put new tires on, only to replace them later

You've not got your brakes rubbing the tyres rather than the rims have you ?
Or tyres rubbing the bike frame or mudgurds?

no, they are disk breaks, the wearing is inside the rim, thanks for replying

Manufacturing fault?

i donno, i hope it isnt, because it means i have to wait longer before i can use it, and i do kinda need that bike

Your tyre pressures are too low and the tyres are squashing down and fretting against the rims. What size are the tyres and at what pressure are you running them?

they are large all terrain tires, i had them at about 55-60psi, tyres max is 65, however the bike manual iv recently discovered said that 50psi is the highest recommended.

it may be useful to note that the wear is just above the wire at the very bottom

The recommended min/max PSI will be shown on the tyre wall.

There is no solution. You need new tyres.
Sounds like the supplied ones were either second hand or faulty.

so you don't think it is the rims, or over inflating then?

You said you didn't over inflate them.

And what rims so you mean? The wheel or the tyre?

What type of rising you doing? Is it off road where you are skidding a lot?

 

[chriss2.0]

i stick to cycle paths and road with some mild off roading (forist paths mainly flat),
i don't do stunts jumps, or anything stupid

the wear is in the beading of the tire and the rim of the wheel i think has gotten rough as a result of the wear because they are re-enforced tiers. will send pics

That looks like brake block wear, buy you say you have disc brakes.
