Need Help With Tyre Psi

[Aznbongsta]

Hi people!

I recently bought myself a set of used rims with tyres from japan and the tyres dont have any PSI readings for me

I dont know why, but this might also sound newbie of me

My front tyres are 245/40/18 Yokohama DNA Ecos ES300

My driver door thing says 36PSI but thats for 17" Rims with like 225 tyres

or should i just bring it down to a tyre place?

Thanks

What does the tyre say on it?

38psi to 40psi will be fine.

on a 35 profile tyre in 18's, 40psi is about right, so in your size i would agree with the 38psi level.

it's a rough guide to start with as some tyres in the those sizes might be better running more/less (apparently the KU36 Kumho's are better at a slightly lower psi than what one would normally run at a given size)

but yeah, start with 38psi and see how ya go
