What condition does the road tire need to be in to be considered unsafe?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Been riding on zwift for quite a while on on of the kinetic trainers and my bike tire feels slicker compared to my front one, but not that significant I think. What condition does the road tire need to be in to be considered unsafe?

Should be fine unless you see cords/casing.

Until your threadwear indicator marks tells you to replace it. If you have a feeling they need to be replaced, replace them!

If the inner tube isn't bulging out the sidewall, it's good to go. I've never had a wreck or even felt unsafe anytime I've flatted on a bicycle. Perhaps other have horror stories but I have never experienced anything remotely unsafe feeling.

You should consider where you are going to be riding and how a flat might impact you in those areas. If a tire is getting close to looking bad, I'll change it a week or so before I do an organized century ride or such.

It's been on the trainer and probably has worn down to a flat profile. This is not ideal for performance, but it doesn't really affect safety unless, as noted above, the cords are showing.

Also, for the most part, getting a flat tire is more of a nuisance than a safety hazard.

No worries.. on your type of trainer, even if the tire blows your axle is locked in.

Yes, probably safe enough on the trainer. If you move on to riding outdoors, maybe treat yourself to a nice new pair as a reward.

If you are having some slipping issues on the trainer, wipe the drum and tire down with some rubbing alcohol to clean it off. That often helps improve grip.

If that stops working, you can take some sandpaper to the tire to rough it up some. Sometimes tires glaze over a bit when used on the trainer a lot, and the sandpaper clears that and adds a bit more grip.

Last option, you can buy grip tape that you stick to your trainer drum, but that will chew up tires and can create a bit of a mess.
