A Worn Through Tyre

Reading Time: 2 minutes
There was a time when I would change the rear tyre regularly. I was changing from an indoor trainer tyre to a road tyre and back regularly. I developed my skill at this art and then the pandemic occured and I stopped changing tyres as regularly. Recently I went for a 74km bike ride and when I checked the tyre a day or two later I noticed that the rubber was gone and the fibres were showing. I went for one last bike ride, and then I swapped the old tyre for a new one.

Frequent Changes When I Used Zwift

Swapping tyres, once you know how to do it takes a minute or two, with the right tools and right level of experience. It took me 15 minutes. It took that long because I haven’t replaced a rear tyre in three or four years so the right habits had to resurface. When they did the process was quick, and painless.

In the past when I changed tyres I pinched my fingers, or hurt myself in other ways. This time I didn’t even draw blood. That’s a smooth and efficient tyre change.

Wait Until Punctures?

I intended to wear it through until the first puncture. The tyre damage was clear. I swapped it. It’s better to swap the tyre at home, rather than have to swap and inflate the tyre on a bike ride with a tiny pump rather than the proper home bike pump.

What’s Next?

The tyres that I have on my bike have been discontinued so I have to choose which tyres to replace them, several thousand kilometres from now. The rear tyre is brand new, and the front tyre looks fine. Indoor trainers ruin tyres because they wear them out unevenly. The bottom is flattened but the sides are fine. The front tyre is fine.

Good For Another Two Years

if I ride like I have been riding then I’m good for another two or three years before I need to swap the tyres. I’m using continental Grand Prix 4000 S II tyres and they last for three or four thousand kilometres before needing a swap.

And Finally

I’m tempted to shop for new tyres but it isn’t urgent, as tyres can last for years, or thousands of kilometres before being swapped. By the time I need new tyres new technology will have come out. I can also buy new tyres when the price goes down. At the moment they’re 10-20 CHF more than at their low point.
