5th gen (2000) prelude
the size is 17x7.5
what offset? 45mm or 48mm?
hub bore- 67.1mm
what is our bolt battern? </TD></TR></TABLE>
bolt pattern is 5x114.3
of those two offsets, +48 will be a better fit, especially if your car is lowered
as far as hub bore goes, you need to make sure you get hubcentric adapter rings for just about every wheel out there so the wheels fit the car properly (they're cheap + most places that sell tire/wheel packages include them for free). don't recall what the Prelude hub bore is but only a few wheels out there are machined to our exact bore size.
And before you ask, 215/40/17 is the correct size tire for the new wheel
Very close to stock diameter (which results in minimal speedometer error)

about 3mm
The +45 wheel will sit 3mm closer to your fender than the +48. It should still fit with a 215/40/17 tire although you may get some rubbing if you're really low.
+48 is one of the known sweet spots for 7.5" and 8" wide wheels on the 5th gens so thats why I suggested it.

Re: Will these fit? (HxClude)
lol you know what i meant! but thanks for the heads up. im not that low and plus my suspension is adjustable so i should be ok.
anything else i should know before i place the order?

I think its all covered but here's a checklist:
1)correct bolt pattern
2)hubcentric rings to ensure good fit
3)correct size tire (correct diameter for the car as well as correct for the wheel - e.g., 205 through 225 width on a 7.5" rim)
4)you have smaller "tuner" lug nuts to mount the wheels as well as wheel locks (I recommend a McGard Spline Drive kit - Summit Racing is a good place to get it)
And then the obvious - wheel is lightweight, strong, looks good

just curious, why owudl the same offset apparently be a "sweet spot" for the same car using two different wheel widths? the 8" wide woudl stick out 1/4" more toward the fender than the 7.5" right? offset is the mating surface of the hub to the centerline to the wheel so unless i'm missing something, if 7.5" + 48 is a good combo, then the offset to get the 8" wide wheel outside edge closest to the same woudl be +42 (.25 * 25.4 = 6.35; 48-6.35 = roughly 42)

I'm going on known fitments that have been posted on PreludeOnline and HT rather than calculations. There's just too much variation with tires and suspension setups so I go by what has worked for other folks. So when someone asks a question like "does +xx offset fit a 5th gen?" I have to make some generalizations to account for lowered cars and varying tire width. Crazy how a 215 tire can vary in section width by 1/2" + across the various manufacturers
Put a 215 Goodyear F1 GSD3 next to a 215 Falken Azenis and the difference is ridiculous.
Anyways, the sweet spot I guess applies more to the 8" wheel where the thing just barely fits with any substantial tire. The 7.5" has more flexibility. For example, the SSR Competition and OZ Superleggera, the only 2 common (I guess you could say) 17x8 wheels for the Prelude are both +48 and are both known to fit well on lowered cars. Some of the other JDM wheels that are +50 or higher in 17x8 tend rub on the suspension components. I'd also refer to the +48 as a sweet spot because guys have run 235/40/17 tires on +48 17x8 wheels with no rubbing (and no more than 1.5" drop). Crazy to think that you can't go a few mils in either direction without rubbing - tolerances are that close sometimes.
I think that +48 is a better or at least safer choice for 17x7.5 because it is less likely to rub the fender lip. +45 should be ok for a lot of setups too, particularly those where the car isn't slammed.
forgot to mention another factor - the increase in wheel width without the tire is not linearly related to the increase in wheel width with the tire. think about it. you can run a 215 width tire on a 7", 7.5", or 8" rim. the sidewalls bend to fit the rim, changing from angling outward ("stretched" appearance) with an 8" to angling inward with a 7" rim. The overall width does not increase 1 full inch when you go from running a 215 tire on a 7" rim to running a 215 tire on an 8" rim due to the sidewalls angling inward or outward. this factor could make one offset ideal for two different rim widths since the actual difference in width once the tire is mounted could be well under 1/2".
wow this is fun
