Hey guys ,

Just got a set of apex wheels with federal 595rs pro tires ,

Fronts are 235-40-18
Rear are 265-35-18

Didn’t know what to set for tire pressure seeing if someone had a similar set up and could chime in?

Edit - single turboed not a daily driver so I’m looking for an agreesive pressure recromendation if that’s possible

Should still go by the recommendations on the drivers site B pillar sticker

Don't think his door pillar sticker is for:
"Fronts are 235-40-18
Rear are 265-35-18"

There's a reason racing bicycle tires are inflated to ~ 90 PSIG.
There's also a reason the front wheel is "Quick Disconnect".
Low profile tires generally have higher inflation pressure, largely to protect against (as much as increased pressure can ;-) RIM DAMAGE when you hit a Pothole.

Hey !
Yeah since my tire sizes are different then stock I figured it would take differnt presures . Didn’t know if anyone autocrossed had these sizes and had a good tire pressure setting

You're not that far off the OEM 225/40-18 and 255/35-18 sizes, just use the suggested pressure for those and work your way from there to find what you like.

I truthfully still don’t understand what increasing or decreasing pressure does / how it effects overall feel
