tire pressure

[lion_g]

i got a set of toyo 235 40 r18 on my car the ones on the back at the same dims just a diff brand cheaper so i got them
they were on like 40 when i got them checked them the other day and now they are down to like 30 :/
i do city driving not highway driving only on weekends...whats a good balance so i dont have to pump them up for long trips or let them down for city driving i want a nice smooth ride no matter where i go.

40psi... get your tyres and valves checked

38 or 40 psi is safe.

you have low profile tyres, you HAVE TO run high pressures to stop rim damage.
