Tire size vs lean burn, gear ratios, etc. What tire size am I after?

That is +~6 pounds per corner vs. the insight combo. And another 2.5? Pounds per corner for spun aluminum moon discs. Total guess at the weight of the disks.

They are also only 1.5% taller. 900 revs/mile vs the stock 913.

But the kicker is, they're 20mm skinnier per corner. That is 80mm less contact patch width total vs. both stock and the insight.

Stop and go would suffer, but I would, in theory, gain mpg at cruising speed. But if +1.5% isn't big enough to keep me in lean burn, it's all for naught.

I have the Honda Insight gen1 15" donuts and they are 4" wide and lighter than the Yaris steel wheels. I was going to use the Continental Tires with a modified version of these Insight wheels for a car project of mine. You can purchase them from Ebay for around $50 USD.

Will they hold a standard hubcap? (Moon disc)

That I am not sure bout I have never tried but I am sure that one of us ecomodders can get something rigged up to work :-) This is what we specialize in after all You did notice I said modified version of these Insight Wheels in my previous post

What did you do to them? Also, they're all $100ish shipped on eBay. : (

Crap all this talk about Honda Insight wheels and RE92 tires got me messed up LOL sorry for the confusion I probably caused

The wheel is actually a Honda Fit not Insight wheel from an 09 10 or 11 year Fit car. Bolt pattern is the same and I think cost is why I went this route instead of the Insight cuz you are right the Insight wheels are more spendy. You can definitely get the Fit wheels shipped for around $50.

Here is a link to one currently on Ebay = 09 10 11 Honda Fit Wheel 15x4 Spare 742470 | eBay

It looks like there are some Civic wheels on there also in 15 X 4 that are even less shipped for like $35. I think they have a 5 lug bolt pattern however. Lots of options for those Conti tires though.

Do you have a pic of them on your car? Are you using spacers? Concerned about offset..

[GreenHornet]

I do not have these wheels and tires currently on a vehicle. If you are concerned about the offset just check what the Fit is and that should tell you if they will work on your CRX without modifications such as spacers. I believe the CRX has a 4 lug 4 X 100 bolt pattern which is the same as the Fit. So lug pattern should not be an issue.
