|I put a nice 1/4" sized hole in my rear tire yesterday on a piece of glass and had to replace the tire. I had 900 miles on the tires which are Conti GP 3000. Should I put the new tire on the rear in the hopes that the front and rear will then wear out at the same time or should I put the new tire on the front. My existing tire looks to be in pretty good shape wear wize...|

|I would rather have the best rubber up front. If you are going to get a catastrophic flat, far better to get it on the back and retain some control over the bike and have the hope of riding it out rather than just going in nose first.|

|Generally we should have our best tire on front, but if your front has only 900 miles and seems to be in good condition I think you could put the new one on either wheel, I would probably put it on the rear knowing that it will still wear out faster than the front.

|Per Chen2's comment, your back tire will still wear out faster. Except for very heavy riders or a LOT of downhill braking, the front tire suffers very little wear. It ages, gets cut and nicked, but it doesn't lose weight due to rubber being worn off. The rear tire does all the wearing due to the power being transmitted to the road. Move your front to the rear, and put the new on the front. Otherwise, you'll have an old, cracked, crazed, and oxidized front tire - not good for cornering traction and a bad place to have a tire fail catastrophically due to age.|

|Does this still apply if the front tire is only 2 months old?|

|It probably does not make a difference in your case but it is good practice to get used to. You will wear out both tires either way. And you will not get any more actual milage out of any two tires on a bike regardless of whether you switch your tires around or not. If you get 4k out of the front and 2k out of the back or 3k out both when rotating front to back you still get 6k out of two tires.
Its your life, put the best rubber up front - its a good and safe habit to get into.

|I guess I just wanted both tires to wear at the same time so if I wanted to try out a different tire later I could get a new front and rear without throwing away good tire.
On another note I read in another thread that you also ride a Cannondale Jekyll. I also ride one, a 3000 my wife got me for christmas. Where do you have your shock positioned and what pressure do you ride your lefty at? I like the bike but I am having trouble getting it totally dialed in...

|Hey, welcome to the club! I also have a 3000 ('01).
The pressure in the shock and fork really is a matter of weight and riding style. I'm 175lb and run my Lefty at 130 and the shock (Float RL - some had RC's) at 200-210 with little rebound. I originally ran the shock at higher pressure to keep things from bobbing but as I learned to work with the suspension I found that I could run lower pressures and get a better ride without inducing bobbing. The bike climbs great, you just have to be smooth.
I run the shock almost all the way in. I ride technical, rough stuff without, for the most part, long downhills. I prefer quicker handling because of this and want the bike to be more upright thus the shock most of the way in. As you thread the shock out you slacken the geometry and slow down the bike's handling and lower the center of gravity all of which adds stability, especially when going down hill fast but hurts low speed maneuverability and climbing.
It took me a while to dial in the pressure, rebound and shock position. I'm pretty happy with the set up above.
Hope this helps - having ridden most FS designs I still think this is the best "non-racing", all mountain dually going.
On your tire dilema, just run the new one on the front, when the rear goes get a new set of tires and save the one from the front for the trainer.
Cheers, Mike AKA the Jekyll..................

|Common sense will tell you to rotate the newer tire to the front, but from my experience....I've had the same tire (Conti GP3000) on the front for the last year, have logged probably 5,000 miles on it, and it shows very little wear...on the other hand, I've replaced my back tire (same Conti GP3000's) three times since the original pair. Forget the old adage that says that the front lasts twice as long as the rear...just replace the tire...within a few weeks you won't be able to tell which one is newer and soon after that the rear will be looking used and abused. And whatever you do...enjoy wearing those tires out =)|| |
