I cannot find the recommended tire pressure on these size. Any input is helpful. It's a Continental Extreme Sport Contact.

 

Usually anything between 32-36 is normal for a smaller vehicle. I run 32 on my civic hatchback and s2000 when driving around town.

I'm sure you could email or call Continental too.

 

32 psi cold per Continental.

 

Every tire has the recommended PSI stamped on the sidewall.

 

I'd email the manufacture the size wheel and tire you're running for their suggestion. I personally run around 30 to 34 PSI on my 205/50 with a 15x7 inch wheel.

That's incorrect. That pressure listing is only a notation during bead seating portion of tire replacement on passenger vehicles with typical street tires.

 

Sure thing. Believe what you want. But yes the recommended tire pressure is in fact posted on the sidewall of all tires.

 

That's the maximum pressure. Recommended is from the car manufacturer for the specific vehicle, not what's on the tire.

 

*sigh* You're usually one to post false info but alright, I'll bite with evidence.

Subject tire is a 205/45R17 Bridgestone RE71R, production date Week 1 of 2018.

Two pictures provided, you're welcome to enlarge and check for yourself. There is no recommended tire pressure, just a warning to not exceed 40PSI when seating the beads.



Please stick to selling wedding table seat covers and handing tools to racers in the sandbox before falsely assuring yourself that you are correct and making passive sly remarks.... Like usual on and off the forum. =)

 

30-34 psi for road purposes, tires only have max psi settings and for inflating the tire to seat the bead, every car has a certain psi setting on your door panel due to tire ware overtime if not followed you might have more inner ware on your tires if inflated too high, too low will cause edge ware on both sides of your tire making a round shape over time

 

What's posted on the sidewall is the maximum safe pressure for that tire, when it is in use. You should always go by the care manufacturer, not the tire manufacturer. It is usually posted on on the driver's door frame. Open the driver's door and look at the frame that is behind the doo.

A heavier car will tend to have higher pressure required, up to the maximum amount listed on the tire. A lighter car will have a lower pressure requried, much lower than the maximum safe pressure.

Using too much pressure will cause less traction as only the center of the tire from side to side will contact the road instead of the entire tread. Too little traction will make the car unsafe. It will spin out more easily when making abrupt turns. This will happen when the rear wheels lose traction but the front retains traction. On a front wheel drive car there is more weight over the front tires, so the effect of too much air in the tires will cause lack of traction that is worse on the rear than at the front. This will also result in uneven wear, and the read will wear out faster.
