What is the recommended pressure for the sumitomo 275/35/18? They're just for street, on 2000 cobra r wheels. Thanks

jdavis96gt,

Since you're just cruising around on the street, I would run 32-33psi. That should be more than enough to get the best MPG and retain the proper inflation. You should also check the tire psi listed on the inside of your driver door. That's the best psi to use for a street tire.

If you ever hit the drag strip, then lower the psi down to 22-23. That will give you the best launch!

Hope this helps!

That's true, but the tire psi is also based a lot on the vehicles weight, more so than rim size. So, if the psi is less than 33psi on your door, I would probably meet somewhere in the middle between the two. That is if you're looking to be exact. 32-33psi will be perfect, anyways.

Enjoy the new wheels!
