Wheel diameters for '89 Prelude?

    I recently acquired a well-tuned 1989 Prelude (not the AWS model) that
    is quite fun to drive. Fuel-economy is atrocious for a 4-banger,
    however; and I suspect the tiny 175/60R13 tires are to blame -- as the
    engine is whining at near 4000rpm going 75mph. 1st gear is also a joke:
    if a snail breaths on the rear bumper, the car is moving fast enough to
    shift into 2nd.

    Could someone post the bolt-pattern specs (four bolts), and largest
    diameter tire I can reasonably put on the fronts without rubbing the
    wells? In the age of $3 gas, I'm willing to trade racket-like
    acceleration for improved highway mileage.

    Also, are there any kits to enable opening the rear triangle windows to
    improve air-circulation?

    hi there
    my 91 'lude has 185/70/13 wheels as standard.
    I think the offset is 100 mm across straights,not sure about
    diagonals(not measured).
    hope this helps

  4. define atrocious? my 87 prelude gets 36-40MPGs. It got WORSE when I
    switched to 195 65 R14s from the 13s it came with.

    I would suspect it needs a tuneup or you have a brake dragging... Is it Fuel
    Injected?

    The bolt pattern would be 4 on 100mm. I'm sure you can go 185 - 70 - 13
    for tires.
