When do you change tires

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

When do you change tires

When do you guys change tires... when they're
1. worn out
2. new season = new tires
3. whenever I fancy trying something new
4. none of the above (besides I am wussy).

Nah I decided against a poll.

Ps: is it just me, or are there a whole bunch of tire-related threads lately?

When they're worn out.

Most people on my team (faster than me) put on race tires for races. I'm too lazy and only have one wheelset, so I just use the same ones (GP 4000).

^^ those are race tires.

I replace them when 1) I can see some of the casing or 2) I bought new tires on sale and can finally justify putting them on when there is a fair bit of squaring off of the rubber

Why is this even a question? When they wear out, period. I will easily go through 3 or 4 rears in a season of just moderate riding.

I suppose if you ride your bike 100 miles a year and the tires are 5 years old but still have tons of tread I might consider new tires, but even then, I would probably just ride them.

Many folks are uncertain when the tire is considered worn and needs to be replaced.

1) When I can see casing
2) When it gets thin enough to cause frequent flats
3) When they rot

I am waiting for the tire I am running to fail. I can't imagine there is much rubber left on there (over 2K on the rear and they squared off at 600 miles) and I ride over glass/gravel daily. Somehow these cheap, unprotected, worn down tires (Maxxis fuse if you are wondering) just refuse to give up. Their number is up, next flat and they go.

Tonight. I did a descent on Saturday that was 9 miles long and up to 43mph. At the bottom I noticed a pretty good sized patch of casing threads on the rear. Time to change it.

When they are worn out, deformed or cut by broken glass.

When I can see through to the casing. I just replaced a pro race 2 after I took a close look at it and could see several places where the casing was peaking out through the tread.

When they easily flat, which is usually before the casing shows up or rotting.

I go through 2 to 3 tires a season typically. When the rear is overly squared off it is swap out time. I will normally rotate the front to the back then put the new one on the front. I try to start the new season on new tires just to start fresh. Removed rear tires will be used for the trainer during winter.

It's not a pure race tire. It's somewhere in the middle. I consider race tires something that lasts under 750 miles or so. You can get 2-3k out of GP 4000 from what I read. They're cheap enough on PBK that I use them for training and racing.

Plus, they come in red, that's hard to find in a good tire.

Same - works out to be about 1,500 miles. Trying to get the last few hundred miles is not worth the flat potential to me. Plus we have a lot of tight descents and more rubber is gooooood.

3) Before any ride of 400 kms or longer if I've put at least 3000 kms on them already.


I'll likely change mine next sometime in May.

When this happens:


I'm glad I got good tires in this case, haha. Descending behind a car, when i saw brake lights. I instinctively reached with my right hand... and locked my rear wheel. Still counting my lucky stars I got good kevlar tires...
