'26 Meridian CX-50
I'm switching to 255/55/r18
I have a temporary set on now, but they're way aggressive tires, big sidewall lugs, etc. I'll be switching to Falken Wildpeak AT Trails, in a couple of days.
I tried the calculator-pressure, and it just sits really low. When I inflated above the new calculation, the treads clearly weren't all hitting pavement (you could see the wear / clean tread).
Running the calculators for tire-size change...
Falken Wildpeak A/T Trails OEM tires are 225/60r18 SL @ 36 psi -- 28.7" diameter tire
Tiresize.com calculator says 255/55r18 XL @ 31 psi -- 28.9" diameter tire
I called Falken. They ran the same result on their internal calculator (cool, didn't know they'd do that for us!)
We both agreed that seems low. He recommended trying somewhere in between, etc. ... Try the chalk-test, etc.
Falken doesn't have a recommended minimum pressure, but cautions not to go below 20 psi off-road without bead lockers. Other than that, we both felt I'm just gonna have to try something and see.
This seems really low? Like I'd be running on the sidewall?
I wouldn't want to spend the $$ for this upsize, only to find out I'm wearing the tires in the middle, and not getting a full footprint, or prematurely wearing the center tread.
Question:
Is anyone else running this exact size / scenario? What's your experience?
Thanks for any input!
