When do you replace 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 replace tires?

Purchased a new Giant Defy Composite 1 this year. I have put 2000 miles on the original P-R3 tires now. I haven't had any flats. I'm noticing a little discoloration in the sidewalls, but no performance issues. How long do you ride a set of tires before you replace them? My riding is probably 70% smooth pavement and 30% chip seal roads. Appreciate any advice on what is reasonable to expect from this set of tires.

Start looking today.

Well, now that you've said no flats, you'll get at least 4 in the next 3 rides.

But seriously, I actually replace them when they become damaged or when I start getting a lot of flats on them (which indicates the tire is getting too thin to repel the normal stuff I ride on).

Buy some new tires from ribble or pbk so when they do need to be replaced your not left waiting like mentioned.

Replace when you can see any casing or you notice they are cutting easily and get flats. 2K is good from a set of stock tires. You might really improve your ride from some new tires. Also if you are a lighter rider you can expect a much longer life than a 200+ clyde would.

your front is probably good, but the rear will probably slowly become an issue in the next 1,000 - 1,500 miles. I've never used that particular Giant tire, but this is typical.

I replace them when they're worn out. Isn't that when you usually would?

There's a couple tell-tale signs I look for when going to actually replace my tires (as 10 Wheels mentioned, I think it's best to buy stuff on sale and stock up for when I need 'em):
When I start consistently getting a flat on the same wheel for multiple rides, I assume that tire is thin/worn out
If there's a chunk/slice missing from the tire (i.e., if I had to boot it to finish my ride after a flat, or, if there's really conspicuous damage at any point)
When I wear through a layer of tire, especially when there is discoloration (more common on my fixie)
After around 2,500 miles, and especially if I'm planning to do an event or race that week.

I'm a lot lighter than a lot of the riders on here (primarily because I'm female) so your mileage may vary. Hope that helps.

Next time you get a flat, rotate the tire in your hand feeling for soft spots. If the tire starts becoming noticeably soft to the touch, then you are already prone to blowouts. You won't even notice until you hit a bump and it blows a hole in your tire and tube. I rode my last set too long until I had patches on dime sized holes worn through the tire from constant blowouts. If you think changing a tube flat is annoying, try fixing blowout holes in your tire as well when you are out 30 miles from home. Sometimes peace of mind is worth the money.

Schwalbe had some Ultremo 23c's on closeout the last time on was on their site, they were 1/2 as much as other sites were asking for the same tire.

I have a set of tires in waiting, the Ultremo's. Not that I'm complaining, but my current Conti's won't die. I'm over 4000+ miles at this point and there still going. I've loved every Conti tire I've tried, the Schwalbes were too good a deal to pass up, plus I'd never tried them.

1. Cords show on rear tire.
2. Remove rear tire and discard.
3. Move front tire to rear.
4. Put new tire on front.

I had a new rim set put on my bike a couple of thousand miles ago and when the LBS swapped the tires onto the new rims they rotated the tires, so my front tire was now on the back wheel and the rear tire was on the front wheel.

I've never rotated tires before, but it seems like a good idea, it evens out the wear rate a little bit.

Conti 4000s have a wear indicator. I use it to determine when new tires are needed.

Since my rear wears at about twice the rate of the front, I prefer to do the 2/1 dance - less work than rotating. My original question was to see if anyone rides w/ cords showing on the front.

Agreed. I changed a set out when I got several cuts on them and got tired of using Shoe Goo to cover the cuts.

Rotation works by putting front on the back, and THROWING out back tire. NOT putting it on the front. Basically you want the best tire on the front. It's possible to recover from rear skid, not so much on the front...
