Changed the standard WRX wheels on MY05 motor to PDR's with 18 inch Yokohama Parada's.

Can anyone confirm what tyre pressures i should be running ?. Do they stay at what Subaru display in the book or should i now refer to something else ?.

Also need to no what the torque settings should be on the wheel nuts as the suppliers advise to re-check after 60 miles.

Cheers.

 

Depends on the tyres really. Pressure itself shouldn't change just due to the tyre/wheel size, but you find that the handling charactaristics of the car will change with pressures for certain tyres. What's the stock pressures for the MY05 WRX?

 

2.3 bar front (34PSI)
2.2 bar rear (32PSI)

Do you think i am safe sticking with these ?

Any ideas on the wheel nut torque settings

 

Yep. I don't have any hands-on experience with the Yoko's, so can't say what works best with them. I've ran 34/32 with Goodyears no probs and 36/34 with some Hankooks and Toyo's in the past. It should be fine with the OE settings, but there's nothing wrong with trying some other pressures and seeing how you find them.

On my classic the wheel nut torque is 70ft-lb. Does it not say in the car manual?

 

New age manual says 72 ft-lb.

 

Cheers guys
