What is the biggest wheels the Fit can take without tire rub?

right now i have a 17x7 in wheel with a 25 offset and a 1.7 drop.

it did rub in barely

[redrumm]

yeah it rubbed a little bit

[jim@tirerack]

It really depends on how much you want to spend on the upgrade. Going with wheels and tiers and reducing unsprung w3eight will improve the handling and looks of the car. If not just going with a wider better handling tire in the 14" will also help.

Can someone please post a pict of the backside of the factory 15's?

The reason is im planning on getting some Kics spacers in 15mm and
the stock studs will protrude past the spacer by about 10mm...i need to
know if the stock wheels have a cavity adjacent to the log holes to
clear the stock studs.

Thanks!

[kenchan]

come on guys, you dont have a few sec to take a quick snapshot of
the back side of your factory wheel that are stacked up in your garage?

[kenchan]

f-king loosers.


there were cavities between the spokes. (before i sold them) lol

hi, i'm currently rolling in my 07 sport fit on eibach sportline springs(1.8F/2.0R) drop. i also have 16x7 rota grids with 205/50/16 tires on them.
i rub a whole bunch, so i'm looking to drop down to 14" rims. with my 1.8F/2.0R drop, what tire size would you recommend to be best in 14"?
thanks.

[jim@tirerack]

You can run 185/65R14, 195/60R14 or 205/60R14. The real problem with the 16" that you have is the tire size. The 205/50R16 is about 1" taller than what it should be. You need a 205/45R16 for the 16" wheels.
If I can help let me know.

The 225/45x17 tires are probably too big in diameter. 20/45x17 tires on 17x7x45 rims are all we could mount even then we get a little rub once in a while. Good tire choice.
Rim width generally needs to be equal to tread, not sidewall, width. A 205 tire is 8.41" wide and protrudes .45" over each side of a 7.5" rim. A 225 tire is 8.85" wide and the sidewall protrudes .42" over the sides of a 8" rim. On a 9" rim it would protrude about .17". The sidewall width increases to 9.35" from 8.85" when the 225 is mounted on 9" instead of 8" rims.
The 7" rim has no advantage with a 225 tire. It takes less air pressure to 'flatten out' and reduces footprint. The wider rim needs more pressure to flatten out and supports the tread better so cornering in better.
Good luck. Cheers.

I plan on getting 17x7 rims. I have a brand new all stock fit sport as of right now don't have any plans of lowering as of yet. And am completely clueless on what kind of tires I should be getting this is the first time I have done this. Would need something that wouldn't rub live in wisconsin so somthing all season. Not too much plans on racing but don't necessarly want to kill my speed and accelaration. Any hints on what i should be looking at or where I can look to find this information.

Any help is greatly appreciated.

Sorry for being the nub.

From what i have read thus far, you will probably be looking at a 205/40r17. Maybe a 205/45r17, but i am still searching that. The only thing that would concern me would be possible inner fender rub while turning, but the right offset/spacers should minimize that.

ALSO - you may want to consider getting a set of summer rims/tires and keeping the stockers for the winter (seeing as you will not be able to sell them for much anyway).

Tires will not weigh you down too much (especially @ a 205/40), it's the rims that you have to watch out for (RE: acceleration)

[MINI-Fit]

For 17x7 rims use 205/40-17

For Wisconsin and for one set of tires with no need to change them for the winter pick All Season tires.

Ultra High Performance All Season tires-
Bridgestone potenza RE-960AS $172 each 400 treadwear
(a very well balanced handling and comfortable street tire for all weather but expensive- if your budget is larger then this is quite good)
BF Goodrich g-Force Super Sport A/S $112 each 400 treadwear
(newly released looks good for handling, works in all weather)

Continental ContiExtremeContact $68 each 400 treadwear (backordered)
Yokohama Avid W4S $83 each 400 treadwear

(the next two are more budget minded, not quite as good in snow)
Kumho Ecsta ASX $67 each 420 treadwear
Sumitomo HTR+ $62 each 360 treadwear
Falken Ziex Ze-912 $58 each 360 treadwear (might be sold out)

High Performance All Season tires-
Bridgestone Potenza G009 $85 closeout at Tirerack.com 460 treadwear
Yokohama Avid H4S $79 each 500 treadwear
Both these are good for handling and comfort, well priced and suited for the Fit in all weather including light snow.

In the same class but more budget minded and not quite as good for snow.
Fuzion HRi $63 each 400 treadwear
Kumho Ecsta AST $54 each 400 treadwear

Stock tires 195/55-15 can be used on 15x7 rims
225/45-17 is way too large for the fit
I will try to test fit a 17x7 rim with 205/45-17 tire but I think it will be too tall and rub a little in the rear under full load of passengers.

215/40-17 or 215/35-17 sizes might work with 17x7 rim. May depend on offset.

hi jimmy
i was wondering if i had me some 16inch rims would i be able to run 45/215 without rubbing?, i am lowered on Tein Basic coilovers. or would i have to roll the fender?
oh and wheel specs are 16x7 and offset +40

[mahout]

If this wide tire were mounted on a 17x7" wheel, it would seem that
the sidewalls would protrude a bit on either side, offering the rim
some small level of protection against curb scrubbing. A 225/45x17 tire is almost 2" greaterin diameter.

That would seem to be a good thing, but what I need to figure out is
if there are any handling / ride considerations for using a 7" rim
versus a 9" rim.


First you must find a wheel with 55 mm offset and 5.16" backspace.
Even then you may get rubbing; almost certainly if you lowered. Why 225, why not 205/45x17's on even 42 mm offset wheels. They work well on my car and no rubbing. A 225/45x17 tire is 1.52" greater in diameter. 3/4" taller and 1.52" higher ride .They will rub period.

Wider rims increase the contact patch, up to a point, and so 9" width at upper limit of mfg range will be better than 7.5" As the rim width reduces there is a half loss in tire width. For every inch less rim there is 1/2"loss in tire width is a general rule.


The wider the rim the more stable the tread is under side loads. Again, up to a point. Usually thats about 1/4" greater than the tread width. After that the tread wants to bend upward in the middle reducing contact surface. That might help rolling resistence but certainly hurt cornering & worsen hydroplaning.
BTW all this tire dimension data is readily available on Tire Rack's website, which is wy they have the premier website in automotive, maybe entire internet. And I don't work for Tire Rack.

Awesome info! Thanks. Keep us posted on the 205/45/r17's also.

Thanks again.

[quote=Charles Lasitter;9034]Tires have specs for section width, rim width, and rim width range.
(Plus lots of other stuff).

Looking at a Pirelli PZero Nero 225/45-WR17, it lists a rim width of
7.5" and a rim width range of 7-9".



I see there are 17x7x45 offset wheels by MB which should let you run 225/45x17 tires.
In passing we do have a set of new 225/45x17 tires that were not claimed by customer that we will sell for $160 the set if youre interested.

I did the test fitting today.

17x7 rim with +42mm offset using Sport Fit with stock suspension.
205/45-17 street tires.
Works fine no rubbing. Felt pretty smooth considering the 45 series sidewalls. Wasn't harsh riding.

Tire diameter is a bit tall at 24.4", causes the Fit to be a little more off the ground by 1/2" and wheel gap is less by 1/2" but OK. Odometer and speedo will read lower than actual.

205/40-17 will be more stock sized.

Just for run I also did a test fitment of-
15x8 rims +36mm offset with 225/50-15 tires and that worked too, front and back no rubbing. It's taller than stock as well and very wide but OK.
205/50-15 and 225/45-15 would also work.

[cavie187]

Good to know. Thanks again.

I need some suggestion plz!!

I'm planning to move on to Coilover with 1" drop Front & Rear, looking to get the WedsSport TC105N - 16X7.0 / 4x100 / +43 offset. What tire I should get without any issue??

Planning to get Yokohama S.drive, I want little wide at the front 215/55/16 or 225/50/16??

If I do different setup at the front and back, 225/50/16 at front and 205/45/16 back. is that a good idea??

thank you
