Can i use a 175/65-15 snow tire on 07 sport wheels? The stock tire is 195/55/15
thx B

 

Certainly if you're not dropped. 17565x15's are about a half-inch taller than the stock 195/55x15's but still cllear the fender wells unless you're dropped or carry a couple of heavyweights in the back seat.
They have a couple of advantahges
1. narrower tire cuts thru now much easier and has more pressure on the contact surface to grab better because of smaller contact area on the road.
2. larger diameter rolls over snow in front easier and therefore make better headway.
3. taller tire also increases road clearance a little (1/4") but every little bit helps passing over snow.

Ok I counted 4 too.
good luck.

 

Mahout
I will have about 150 pound machine in the trunk. But one bit of info that I left out is that i am going to put the 07 sport wheels on my 09 fit sport with stock suspension.
thx for your help

Aha, Since the stock wheels on an 09 are 24.1" diameter you should be OK if you got away with carrying that 150 lb machine then without difficulty on the stock tires.

 

The 175/65R15 is actually even better for the winter and they fit fine.
If I can help with the tires let me know.

 

2000 Honda Civic wheels. 14 inch of course. They fit, but it is close. They are also hubcentric correct. I will be using these for snow tires. This is an initial fitment and in no way means 14s will fit any other 09 Fit. But, if you're wanting to try, the Honda Civic rims are a good choice.

 

Now your speedometer will read 40 when you are actually doing 30...at least you'll think you're going fast...

 

No, a 185/70R14 has the same outer diameter as a 185/55R16. Speedo will read the same.

 

OK, I’ve exaggerated the mileage…but it will be off BECAUSE a 70% tire is taller and will compress more than a 55% tire to the point that your effective rolling diameter will be smaller. Sooo...YES!

 

Effective rolling diameter, of a radial tire? Do you also think that setting a tire to 32psi prior to installing the wheel on the vehicle will result in a higher pressure when you sit the vehicle down on the tire? You're not helping yourself when it comes to being knowledgeable about tires

 

Just about all tires make these days are radial…even truck tires radial plied…some old truck tires are still bias plied and earth-moving equipment still use bias plied tires…so, moot point.

Now your second statement also does not make any sense either…you’re implying that you remove your snow tires to check the pressure????

And thirdly, I’m not trying to help myself…this is for the sake of everybody else here on this forum. If you want a little tire theory, all you have to do is ask…

 

SOME Drag tires, trailer tires, "new" off road tires, ATV tires, motorcycle tires, and etc are bias tires. My point is not moot, the characteristic you were giving, "Effective rolling diameter", is more along the lines of a Bias tire and that is why I made the point. Bias tires can grow or shrink with a change in pressure or load. Radial tires by construction, from my research, resist changes in circumference due to pressure or load changes. It is the circumference, not compressed diameter, that determines the distance traveled per one revolution of a tire (and thus, speedo readings). Circumference is not directly related to the compressed diameter of a loaded tire. Tire construction and properties are just not that simple. Radial tires maintain a pretty consistent circumference regardless of normal pressures and loads. Your previous statement about 55 and 70 series sidewalls is incorrect. Then again, I COULD be wrong, but I'm not the one offering tire theory for the sake of helping people. If you are trying to help people, at least make sure your info is correct. I would say we're getting off topic, but most people do by a snow tire that is narrower or a smaller diameter wheel, and is therefore a different series tire. So, it is relative to the topic.

 

The 185/70R14 tire is within 2/10" of the OE Fit tires. It is not going to throw off the speedometer more than maybe 1 mile per hour at 55 mph. I will say that we do not show the 14" clearig and working on the 09 Fit. We only list up to 15" but if you get them to clear they do have enough load capacity so you are fine.

I am not really sure where all of the bias versus radial tire thing is going.

 

you ever find out if the 14" or even 13" rims work? i'm needing to throw on my old CRX snow tires and they are 13" rims with185/80/13's

 

2/10th's ?!?!?!? dude, reduce your fractions. it should read 1/5th

 

It is better to remain quiet and be thought a fool, than it is to open up your mouth and remove all doubt.

I know that education is expensive, but how is stupidity?

 

Actually theoretically it is correct that setting tire pressure prior to installing on the vehicle will increase the tire pressure when mounted on the vehicle. When the tire supports the vehicle weight it deforms the tire and reduces the interior volume. That increases tire pressure. PV/T = pv/t.
However the change is not great simply because much of the weight is carried by the tire structure rather than the air pressure.Its also why if you change air pressure from 35 to 30 psi the contact patch doesn't change by 16.67% but a much smaller change thanks the stiffness of the tire carcass. And the more hipo tire the smaller the change generally. Does change the spring stiffness of the tire and car considerably. Yeah, it is rocket science.

 

Noooo. Tire structure determines the effective rolling radius before tire pressure does. If you really want the info consult revs per mile on tire rack for two tires to see just which 'compresses' more.

 

Noooo. maybe 62 at 60 mph.

 

Still off...at least 3%

Exaggerated to make a point.
