My 95 accord coupe had stock tires of 185-70-14 in which they say 32psi all around is good

My question, do I use that same pressure in 215/35/18's?

the tires are spec-2 prada's..don't know if it makes a difference..tires say never inflate past 40psi..

 

Just watch the pressure if the tires are pretty wide, or you'll wind up with the center tread going bald really fast, due to the width of the tire being so large, the tire tends to "balloon" out so I'd go with say 30 and see what you think. IF they handle like crap with 30 then up them and just check for odd wear.

I'm no pro but this is what I've noticed with several different cars with varying tire sizes.

 

i put my 225/40/18's at 33

 

I've been recommended 40psi for my 215/35 18's
