Found a nice set of wheels 15x6.5 +45 offset. Tires are 185/55/15 will this fit alright or too high offset? Stock height right now but will have coilovers soon

 

Technically, that setup should work just fine with no rubbing. that said, there are other issues to consider.

• 185/55/15 is too small of a tire. it will throw your speedometer, odometer, and warranty off. you should be running a 185/60 or 185/65 to be close to stock. 185/55 is more than 4% off of the stock size so you'll be about 3mph slower than your speedo at highway speeds.
• you'll also be sitting about 1/2" lower (and the fit is already pretty low - also your fender gap will increase by 1/2" so your wheel wells will look bigger.)

The185/60/65 is about 1% off either side of the stock size and will work best. I run 185/65/15 on my snows and they work well.

Those are gonna look real tiny, but should "work".

 

It sounds like a practical hassle free size to use since you will be lowering your car.. You will be turning a few more revs when driving because of the change in final drive ratio but the reduction in rolling resistance with the skinnier tire will make up some for the slight loss of gas mileage.. You should notice an improvement in acceleration and the steering will feel a little lighter also. The diameter is only 0 .33" smaller than the tire size used on a 1st generation Fit Sport and narrower by 0.39".

 

Lerts do the math again.
185/55x15 tires are 23.01" diameter; thats 4% as stated compared to 185/55x16' at 24.01" but the speedometer error at 60 mph is 2.6 mph. The 185/60x15 tires are a good bit heavier and will cost you probabkly 2 mpg.
If it doesn't bother you to register 1040 miles on your odometer for traveling 1000 miles the 185/55x15 tires are good at the right price.
Yes it will sit lower by a half inch but that not a problem to most who install reduced ride heights of 1 to 2 " because it will corner better. The Fit doesn't really sit very low by comparison with other cars which is why most of us lower ours to corner better.
good luck.

 

I run 185/65R15 snows and I am lowered on Swifts.

I suspect your wheel offset is OEM 53 or 55 mm and naturally a half-inch larger diameter tire will fit. !85/65x15 is a good choice for snow tires too.. OTOH that doesn't look lowered by 1.5" either. But even so with OEM offset should work well for 185/65x15 tires.

 

I took a chance on some 205-50-16 Goodyear Eagle GTs even though I knew the the increase in rotating mass, larger circumference and rolling resistance was going have a negative effect on acceleration and odometer, speedometer readings.. What I didn't expect was that even with the odometer showing less mileage than I was actually driving, there was a fuel milage increase of 2 to 3 MPG at highway speeds... I can only assume the reason for this to have happened was due the inertia of the heavier, larger diameter wheels and tires....

 

TC, you still have the GD right? 205/50/16 is stock size for the GE (to clarify for the Original Poster).

I run slightly larger diameter than stock snows and found that to calculate the actual mpg of the vehicle on snows, I had to add the error correction of an actual mile which was a drop of 2% so my actual fuel economy when I Was getting 40mpg was just about 39mpg.

Of note, my snows on 15" alloys were lighter than my stock tires on 16" alloys. Now that I'm at 205/50 on the stock 16" alloys, my winter setup is definitely the lighter of the two.

Yes, the 205-50-16s mounted on Kosei K4R wheels are on my Gd3 at this time.

 

More than likely its due to the decrease in effective axle gearing; if you drive on level ground - no acceleration - and at steady speed - no acceleration - going to a larger tire diameter is the same as replacing the 4.29 with 4.11 or 4.56 with 4.44 gear atios. That will result in higher mpg's if you're driving steady on level ground. But if you're not ...
