Do you mean like........"What's the amt. of time they are optimal"?............or......."How long will they last, before popping"?

Although I am sure that others have, I have never worn a tire down to the cords. Usually way before then I manage to get a bad enough cut or hole in the tire that I needs to be replaced.

Inspect your tires regularly for exposed cords and larger holes, slices and cracks. Also, if the tire is old, inspect the sidewalls for cracks. When is a hole too large? When you look at it and say - that's worth $50 ($40 - whatever) for a new tire.

If it were me..........I'd put new tires on, now. Then, I'd buy an extra set and put them on a couple weeks out from my HIM.

Then, switch back to the "training" tires, after your race. Use the "race" tires for future LC races......or, make them your "training" tires when the others are worn.

You can buy Continental GPIIs (really popular tire that performs well) for $70/pr if you watch Ebay.

thanks, i will keep a eye out for them. i may try latex tubes out for awhile. i trained for and did a 100 mile ride last year with butyl tubes and did ok. not worried bout time for the him (if i can make the swim, but not this thread) so not sure its worth the extra money, but if im changin them out anyway thought i would try them.

i looked and will prob get them. seems like pretty cheap insurance. however, i have another stupid question. my original tires on my giant defy 1 were completely slick. these look to have some tread. how will that affect roll resistance. i was thinking about just ordering more like the originals if i can find them

The Continental GP 4000s II with latex tubes are going to be waaaay faster than what you had on before.  I'm sure they would be way faster even with butyl tubes.  You can get them for $35.29 each at Merlin cycles right now.  Probikekit and Wiggle have them on sale for time to time too.  I operate pretty much the same way as NC452010.  I put new tires on a week or two before my "A" race.  If I don't have another big race for the remainder of the year I'll just leave them on...they are fairly durable tires.

Some tires, like the Continentals, have a wear indicator on the tire.  It's a little hole in the tire...when the rubber wears down flush with the bottom of the hole you should replace the tire.

The answer depends on the rider weight, tire size, and wheel. The rear wheel takes up 55 to 60% of the load.

My girlfriend (130 lbs) rode a tubular tire for 7000 miles. The truly amazing thing was she had no punctures.

I'm 175 lbs. I've logged 4000 miles on a Conti Race 23mm wide tire on the front wheel. I've ridden Conti Gatorskin 25 mm on the rear wheel for 3000 miles. I'm logging 3000 miles Vittoria Rubino Pro 23mm front wheel and 2000 miles for the 25mm width on the rear wheel. All these tires are training tires.

I've had good luck with Vittoria latex tubes.  They're not cheap and you do have to be careful when you install them (making sure no part of the tube is pinched between the tire and rim) but they are worth it in speed and comfort.  I would only use them for racing though given the higher price.  Put a butyl tube in your flat kit when racing...you don't want to fool with installing a latex tube during a race.

Probikekit has a decent price on them.

thanks again guys. the front tire has about 2500 miles on it, and the back has about 1500. they are 700x25s, and i weigh 180ish. i will be training for a him this year so will be putting quite abit on them. so i think i will change em out and hope to avoid flats. the extra speed would be well appreciated beings my bike is a road bike built for comfort more than speed. i might go ahead and buy em and just keep them, use what i have for training, then a mos or so before the him put them on an ride.

Depends on so many different things... how good/bad your roads are, if you ride in terrain where you accelerate/brake often and abruptly, etc.

For GP4000S, I usually get about 5k miles, but that's pushing it towards the end. Your tire should have minimal flat area in the middle and no visible cotton threads (that's a telltale sign that you went too far). And you should have no flat spots from braking (locking up will cause this).

great info for a guy that truly has not clue. appreciated. my back tire blew out on the first ride i made after buying the bike brand new 2 years ago. had a gash about a quarter inch through the side wall. i had never had a real bike before so figured it was par for the course. i looked around and there was no glass etc around where it popped. now im thinking somewhere along the line someone or something gouged it and the ride let the tube through the gash causing the blow out. i may well be wrong and dont really care, it was 2 years ago. anyway, lbs repaired it and away i went. last year they suggested i put another tire on it so i did. but, my ocd kicked in and really bothers me having 2 diff tires on the bike (i know i know). anyway, i have 2500 on the front and 1500 on the back. i figure i will put around 1500 ish again this summer raising that total to a level im not willing to drive 14 hours to a him event and compete on. so, im gonna buy the cont gp and latex tubes. train on my tires i have now til bout 6 weeks out put the new tires on just to have a few rides to ward off any blow outs etc like i had with my first tire. then go race. will carry my regular butyl tube is case of a flat (alhtough i have to learn how to change a flat, never had one in training and did alll the you tube videos but havnt used the info in 2 years so kinda rusty) and go to it.
i appreciate greatly the advice. cont gp40002 and latex tubes here i come. wonder how much diff in speed i should expect.

Conti's have a little hole on the tire that indicates wear. When it isn't a hole anymore. . . time for a new tire. I'm not sure if other tires have this. . .so maybe take a look and see.
