So, as part of a trade, I got an old 4 ply 36" Nimbus Nightrider, and it’s got some cracks on the sidewall. (I knew about the cracks - the trade was all good).
I’m not super concerned, especially with it being the 4 ply version, but I was just wondering who has tyres with cracks on the sidewalls and rides them with no concerns, and if anyone’s actually had a failure of a tyre with cracked sidewalls.
I don’t worry about cracks. One of the Nightrider tires I’m now riding is cracked quite a bit and run it a the max pressure of 65psi. The strength of the tire is the cording and not the rubber coating.
I had a cracked 20”, but it was the dry rotted original tire from ~‘70s and it lasted through my learning phase, some hopping and messing around in the driveway, and a few miles of riding before blowing out, but not out the side, right out the top of the tire I think. So I guess the sidewalls still held up better than the tread.
