Creaking Noise When Inflating Tyre?

    Hey guys,

    The GF recently bought a bike to cycle to college in September. We picked one out from Halfords for €160. I'm well aware that they're BSOs but we picked a hybrid with a rigid fork and 700c slicks. She ended up getting a hardtail with a suspension fork and 26x1.95 Kenda knobbly tyres...

    I'm not going to even get into it, what's done is done, anyway, the tyres are rated 40-65psi but when I was pumping the tyres up I noticed the rim started to creak once I hit 40psi. Since it's a BSO, it's just a generic rim. I was hoping to put my old 1.35" Marathon Plus on them from my MTB because her commute would be easier being puncture free, but they're 80psi minimum I think.

    I'm not comfortable inflating these tubes, what do you guys think? I don't think the rim can handle the 65psi the tyres are rated to and I doubt she'll return the bike.

    I know Halfords are ****, but this is an absolute joke. Assembling a bike with unsafe brakes and gearing?

    a few weeks ago I had the same thing happen when I was infalating the tyre,i was a biy worried so put on the safety glasses,deflated the tube and pumped it a second time and it was till the same,about half an our later a spoke popped so id say in my case the noise was the metal failing in the spoke

    Any rim on an -adult-sized bike (even a BSO) should be able to take 65 PSI, especially if the tyres supplied on it are rated to that pressure.

    As a check, deflate the tyres to around 30-40 PSI and examine how the brake pads sit against the rim's surface when you pull the brake - they should lay flat, touching from top to bottom (if they don't, it's an adjustment issue, but not relevant to what I'm getting at here) - either way, note how they sit on the rim, and then inflate the tyres to 65 PSI and check again - many BSO's rims are so poor that their walls spread out under the load from the tyre pressure, and then the brake pads don't sit against them properly.

    If this is the case, then I would invoke the Sale of Goods Act, as mentioned by Lusk_Doyle, specifically that the product is not fit for the purpose intended.
