As the title says, I would like to hear what the experts think. I have an 06 330i sedan, has the sports package, with the runflats. BMW recommends 38f, 42R for those tires. I have upgraded to 19in with 235/35 and 265/30, and want to hear what you think for pressures. I ran them tonight with the OEM pressures, and seemed high (like bricks). I did search and I saw a few say 36f, 38r. Thanks in advance.

min recommended is in your car manual, max is on the tire, max recommended by manufacture is also in you manual

for 335i min is 32psi i believe, max is what you said 38-42, tire max psi is on side wall and should be about 50-55 maybe. its probably not a good idea to run your tires close to 50s though

max recommended for my car (s2000) is 32, i run about 36-38

Sure, sure I thought there was some range specified somewhere, would never run it at max (unless it is fully loaded), which it never would be.

Any others with advice on the pressure? So many running these wheels, there should be something of an idea.

I have 19" 235/265 Hankook V12's and I run 38/38. That seems to be the sweet spot for (in my personal opinion) for these tires. Not sure what you're running, but I'd suggest setting them at something and going for a drive. Seeing how it does and adjust accordingly.

I have the BFG KDWs, I have had them at 36f, 38r, and them seem ok, but I drive really aggressive on turns, just want to make sure I have enough pressure in the fronts.
