I have a 09 sport, would like a large & wider tire
I would like to make it 1 size taller and as wide as I can go w/o rubbing

 

The size tires you can run on the stock rims are:

Stock size: 185/55/16
Little wider: 205/45/16
The Widest: 215/40/16

As far as taller goes, all side wall heights are determined by the width you are running. Example the 185/55 is the same height as the 215/40.

The Fit would dramatically improve with wider tires when accompanied with lowering springs and hopefully someone will design a stiffer rear sway bar here in the U.S. (there maybe one... not sure). I would wait on the 215's until someone post some pics up because they could balloon out which would hurt handling.

 

Sorry dude all this stuff irks me
What # makes the tire taller?

 

are you saying i cant go taller and wider at same time?

 

Can go wider but not taller. Your speedometer will be off if you go taller.

The second # is the height of the tire. The height is determined by the first # which is the width. Go to discounttiredirect.com or tirerack.com you can plug in your car and they have how-to sections on reading tire sizes.

 

Actually a better size would be 205/50/16, it is only .25% smaller than stock
215/45 is 1.67% taller, 205/45 is 3.13% taller- that will really mess up your speedo....

 

What he said ^^^

205/50/16 is the tire size you need.

 

on 16x7 rims whats the largest tire you can go with without rubbing? (no lowering springs)

 

I honestly dont know... but why would you want anything wider? Your gas mileage will suffer, your car will be drastically slower and wont even handle as good. Not to mention itll look like crap without lowering springs.

 

OK so can anyone recommend a 205/50/16 tire with a very stiff sidewall?

 

how ds wider = slower? i dont want to lower my car either

 

Wider tires usually = more agressive (stickier)rubber = more rolling resistance = slower car. Helps with handling/cornering though

 

Thanks dude I was worried some1 might take that wrong.
I was shooting for a more aggressive look, w/ beefier tiers and I don’t want to have to look out for every pot hole

 

Whats a good tire size for the Base 15 inch model? OEM size doesn't offer many options.

 

Hijacker!!!

this 1 talks about the base Fit

 

Just replaced my stock tires today (kept the alloy rims) on my 09 Fit Sport with Yokohama 205/50/16s. The ride is so much smoother (big time) and the wheels are perfect -they fit the wheel well perfect and give the car a more substantial stance.

I HIGHLY recommend these!!

I got them at Discount Tire --part number is YK520 BW 31714

I will try to post pics in the next few days.

 

I replaced my stock tires with the above size in Goodyear Assurance Fuel Max because I wanted something that was low rolling resistance.

They also have a better ride and grip than the original tires. Somewhat quieter too. Not quite like Michelin MXV4's, but definitely better.

The size is almost perfect because like another poster said, size change affects your speedometer. My speedo is just about dead on now with the GPS. The difference is miniscule.

A side benefit, which I was hoping for, is improved gas mileage. My last tank was 41 mpg in normal driving. Usually I'm averaging around 38 mpg.

I really need to average this over a longer distance, but it is encouraging.

Usually a wider tire will lower your gas mileage. The rolling resistance offsets this.

 

I first went to the 205/50's when I had to replace the stock Dunflops on the old Protege 5. Stock size on that was 195/50/16 - very hard to find decent replacements for that size!!!
At the time I went with Fuzion ZRI's (they've stopped making them in the 205 size now)
Great tire in the dry very good in the wet!!
When the time comes, may look into the Yokohama's, running a set of Avid's on the wife's Miata.

 

205/45 taller than 215/45 doesn't make sense. For the same aspect ratio, a narrower tire should be smaller in diameter; i.e., shorter gearing.

Hmmmm.. I used that same calculator to post the size comparison... guess I mixed up my + & - ....
I bow to your superior mathematical skills!!!
