Tire pressure.

Just put my 19s on from am and I'm trying to find the recommended tire pressure for them. The sticker on my door panel only gives it for 17s and I can't find it on the tire? Any help appreciated. They are 245/45/19 pirelli.

Thx, I see the 50 psi max on the side wall but I'm just not sure what it should normally be set at. It thought it shouldn't be that hard to find but apparently I was wrong. Checked pirelli.com, door panel and side wall of tire. Thx for the research BTW.

No problem. I'm guessing the store that did the install can help you out an a minimum pressure to use based on your driving load.

50 is max and when rolling it will increase and possibly blowout. I'd set it at 40-44 to be safe.

run 32 or about there in them, you may have to run 35 if you have a sensor

Just called pirelli because I coundnt find a set psi and they said for our v6s at 19" should be at 32. Thx guys for the help. They are at 40 now, gonna go adjust it. I really love theses tires and wheels from am the fill the gap perfectly. I know it doesn't make much sense but I filled up Sunday with the new tires on and reset my avg mpg. I was averaging 12L/per 100km, and now its 11L/ per 100km and the tank is almost done! Shouldn't it have gone the other way? Confused.
