Conti 5000 tire pressure
I just bought these tires (700 X 25C). I wanted these tires to increase my speed for race day due to reduced tire resistance, as advertised, and the tire's popularity. I know it won't make a very large difference, but more speed is still better than less speed given the same degree of wattage I can produce. Based on your experience or knowledge, what tire pressure front and back will optimize milaegage improvement (whatever it may be)?

Google 15% drop pressure, consult chart. Adjust to taste.

Also, invest in a decent standa lone pressure gauge to make sure you have the pressure where you want it...pump gauges are not reliable. They're good for getting in the ballpark, but are not reliably precise.

As an example...I weigh about 160 and would run 85rr/75frt w/ 25mm tires. Especially Contis as they tend to be a little wider than stated size.

Then go ride the tires and adjust the pressure as necessary after some test rides nrsmd. The outputs are not perfect, but without a lot of fuss will get you very close to a useful pressure from which to start experimenting with the right pressure.

True, however, there are a couple of reasons an accurate pressure gauge are helpful, in my experience.
1) You need to start somewhere.
2) once you know what works fro a given surface with a given tire, it's helpful to know what the actual pressure is, so that you can replicate it without another round of trial and error.

To get the same feel of suppleness (as my Veloflex and Vittoria 25mm) on the 5000s, I have to reduce the pressure from my usual ~100 psi to about 85, thereby increasing the rolling resistance for me. Rider weight =190lbs.
In my opinion, the Conti 5000 may have slightly lower rolling resistance at equal tire pressure and (reportedly) good durability, but has a stiffer the ride quality than the comparable price competitors. If it proves out more durable in my riding conditions, that is a reasonable trade-off.

I ride my 28s @ 60psi rear 54psi front. Great ride at those pressures for that width.
