Running 2 different tires (GP 4000S & 4 Season), which should go in the front/rear?

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

Running 2 different tires (GP 4000S & 4 Season), which should go in the front/rear?

I bought a CAAD10 used which had a Continental Grand Prix 4 Season in the front and a Vittoria Randonneur in the rear.

I got flats and noticable cut(s) in the Vittoria so I'm replacing it with a Continental Grand Prix 4000S since I'm eventually starting to do road races. I'll probably switch out the GP 4 Season, but not right now since it's still got plenty of life left.

So if I'm running a 4000S and a GP 4 Season, which should I put in the front and which in the rear? I know that the 4000S is known for better handling but the Season has better flat/puncture protection.

The newer, better handling tire should always go up front.

Really? I imagined that the wheel that carries the most load (rear) would benefit from the better tire (4000s).

Listen to the other fella's.

The front is responsible for the steering and most of the braking. The tire with better grip (GP4000s) should be there.

And since the rear generally wears faster due to the higher load, it also makes sense to put the more durable tire (4 Season) back there.

I mixed GP4000s with a GP4000 on the rear and it was not a good idea for fast corners. Hanging it out at 30 mph on asphalt and 1" tires is fun and exciting. Almost as much fun as a pedal strike at 27 and 50ft later the back tire meets ground in a big slide.

The rider benefits the most by having the best most reliable tire on the front, since loss of the front tire is often more catastrophic than loss of the rear.

As others wrote - newer/grippier up front. If both are equally new I'd probably go 4KS front and 4-Season rear. But it's a bit like driving a car with summer tires on front and all-seasons on rear wheels. Also, your desire to race should not dictate 4KS tires - it's as good racing as training and then there are so many other ones which might be better of worse depending on conditions etc. Congrats on the new CAAD10

Are both the same size?

If not I'd put the bigger of the two up front.

Both are 23's, I'm gonna put the 4000 S in front and the 4 Season in rear. Eventually I'll have 4000 S for both. Thanks everyone

When you get the new one, put it on the front and rotate the used one to the rear. As the rear gets squared off and worn out, keep rotating that way.
