Tire pressure

Ryguy29 · 02-25-2014, 08:16 AM

Wondering what psi I should be running on my 20 inch falken 245/25/20

snj1013 · 02-25-2014, 10:21 PM

Doesn't sound like a correct tire size for the F10 chassis? What car are the tires on?

Ryguy29 · 02-26-2014, 05:53 AM

They are aftermarket rims that are on a 528

You mean 245/35/20?

Whatever is on the doorframe of the car is what the tires are supposed to be set to unless that value is higher than the maximum pressure allowed by the tire manufacturer

I know it says it on the door but these are aftermarket wheels and tires , they are also 3 inches bigger than my stocks just looking for a good psi to run year round on the new wheels...

The reason the pressures are listed on the door frame is that the car has been tested to react safely and predictably with those pressures. The tire manufacturers always tell you to inflate the tires to manufacturer's specifications on the door frame. There isn't much discussion beyond that except if you are looking to run them lower to improve comfort on 21" wheels when the car is delivered with 19's as stock. If that is what you are after, 21" wheels with lower tire pressure isn't really the answer.

I run 245/20 and 285/20 with 35psi. Rides nice, but don't know about tire wear.
