>>1503149I never have. Get some good tires. Some are very prone to flats, some are not. (example regular Panaracer Paselas get flats all the fucking time, but Panaracer Pasela PTs which are very nice tires never get flats) And don't ride in the gutter/curb where all the debris is. And fill your tires up before each ride since they lose air over time from sitting and low pressure = likely to get flats.
>>1503135I have never heard of a rim providing tire width recommendations but it sounds like that's what it's doing. Reference pic related.
