Default swapped wheels big difference!

So I was here complaining about my mpg with my old wheels I had on. I was skeptical that oe size wheels would make such a dramatic difference. I purchased my 02 manual insight in may and started learning how to drive it for optimal mpg. It came with 17 inch wheels on low pro tires. Well thanks to scott another board member I tried his wheels out and wow the difference was incredible. Well I've been scouting for a set of wheels for cheap since I was recently laid off of work and I found a set of aluminum wheels off an older civic and had kumho 165 65 14 tires on it. It was a noticable difference with these but I know that the stock wheels with the re92's were much lighter and rolled much easier.

Well my prior best tank was 52mpg with about 505 miles on a full tank (manual calculation)

So far on this tank im at 64mpg and I just had my best trip of 76mpg and i'm driving slightly faster and able to maintain lean burn much easier (computer calculated on display)

Once I start working again i'll no doubt find a set of oe wheels and re92 tires.

A 1st gen insight with 17"s?

For Real? I wouldn't think they'd even fit. What size were those tires?

Yeah, I'm sure it made a massive difference. OE Insight wheels with RE92's will probably be good for another 10-20% over Kumho rubber on civic wheels. You probably shaved 20lbs per corner of rotating mass.

Not sure why you would be skeptical, though. There's literally hundreds of threads on ICN with hundreds of owners who've all come to the same conclusion: There is no beating the OE wheel with RE92s. Any other wheel costs about 5%-15% mpg, dependent on size/weight/aero. Any other LRR tire, such as Michelin Energy Saver costs about 5% mpg. Any other non-LRR tire costs 10-20% mpg.

I dont remember the size of the tires but they did fit easily. I know there's many threads regarding the tires, but not many threads with larger than oe size wheels.

I just bought a 2013 on steel wheels. I have been searching for a set of lightweight aero wheels that are the same diameter and width as OE. I have been looking for some Canadian Honda Fit LX wheels from about 2009, they look very similar to the 1st gen insight wheels, but no luck as yet.

Sorry this is G1 thread. Most G2 people would like that information posted on their forum.

Yep, but I thought it was not too far off topic, I figured the some of the G1 guys knew of the Fit LX wheels as they are 4 lug and while they are 15s instead of 14s they do have the same look. I was hoping to hear somebody say that they knew where to get a set.

The moment of inertia of a thin ring is twice that of a cylinder or thin disk of the same radius and mass.

If we have two wheels with the same mass and diameter, yet one of them looks like the G1 insight wheel, and the other looks like a sporty wheel with very few spokes, Then the spoked wheel obviously has more of its mass on the outside ring. The wheel that looks like a disk will require less force to accelerate.

Anyway. OP when finding your wheels, weight is important, but if two wheels are the same weight, pick the one that looks like more of the material is closer to the center of the wheel, not a sturdy rim supported by very thin spokes.

Yes, the gen 2 is 4x100 and fit wheels fit. Most gen 2 owners go with tires they like vs higher mpg for the better handling.

there are a few decent choises of OEM wheels out there. I have started taking weights of my different wheels and tires.

96-00 civic HX wheels with my 175/65-14 Hankook I-Pike winter tires.
-27.300 lbs. each 109.200 lbs. per set

00-06 insight wheels with OEM bridgstone RE92 tires.
-22.712 lbs. each 90.848 lbs. per set

thats a difference of 18.352 lbs in rotating weight.

maybe we should start a thread with different tires/wheel combos with precice weights (no bathroom scales).

I will weigh the OEM insight wheels with the worn out cheapo tires that are on the front soon.
