Tire Pressure

On my '99, I have swapped my stock 14x6 rims out for a set of '01 SE
16x6.5 rims. I'm now running 205x45 R16 Yokohamas and wondering if I
need to up the pressure for the lower profile. Anyone out there have a
car that came from the factory with 16"? If so, what does it recommend
on the door jamb? Thanks!

26 psi all round

It's not just a matter of "all tires." Your suspension is different from
the '99, and your lower profile carries more risk of wheel damage.
Follow whatever the door jamb sticker advises as a minimum pressure; if
you drive hard, you may get crisper response by adding another 2 or 3
psi. If you just cruise, overinflation wears out the tread centers and
yields an unnecessarily harsh ride.

As for the OP's 205x45 R16, I would run 29 or 30 psi all around.

Where does it say that? I'm skeptical.

Those are the factory-recommended pressures for a Mazdaspeed Miata.

OK. What about the Mazdaspeed would call for higher pressure in the front?

Just a guess, but perhaps Mazda wanted to ensure understeer on a car
that can break traction easily in the rear.

Hey guys, I did 'search the world over' as they say to try to find the best
the best compromise of my particular ratio of looks / weight / price. I
ended up with OZ Racing "Ultraleggra" 16"ers. IIRC they cost $189 a piece
and weigh 14.5 lbs. Most normal priced 16's run 19 to 21 lbs and as Pat has
mentioned when you get down to the ultra-lights (11 to 13lbs) the prices
skyrocket to $300 to $350 per wheel. The OZ's are he

(watch for line wrap!)

They're not horrible to keep clean but anything seems easy after the miata
BBS wheels!

Good luck,
