thanks things really got cleared up with the width divided by 1/2 + offset. ....i nominate the above post as wheel fitment for dummies... page #1

I'm curious as to ReTed's thoughts on this setup.

Tires are 275/40/17 Kumho V710's on 17x9 27 offset.
The fronts stick out about a 3/4 inch from fender and the rears stick out maybe a 1/4 inch.



Here's the orig thread

Think with a 275' tire that has less width I could tuck it? Since the kumho race tire is wider than most 275 reg tires. Think I could make this work on the street? Or maybe just the track?

this is a great thread. i have decided to go with the following:

wheels: 5zigen FN01R-C 17x8 +35
front and rear

tires: Falken Azenis ST-115 225/45ZR17

i know these should fit with no problem, but i was wondering if anyone knows how this will look. the fronts should be nice, but do you think the rears would look better if they were 17x9? i don't really want to do a staggered setup like that though...

oh yeah, i should probably mention i don't plan on a body kit yet. however i am planning on suspension upgrades, in the order of aftermarket springs (1-inch drop max) and shocks.

thanks

can someone tell me if a blitz type 01 17x8 all around with a +44 offset fit my FC? any help is appreciated. thanks.

Race tires, in general, are narrower than their street tire counterparts.  The sidewalls look straight enough, so a +35 on a 9" wide rear wheel will easily fit.  You could try a 9" +40, but I question if this will clear everything.  It's going to be close to get the tire to tuck into the rear well.

Have you tried to check the inside clearances on that FC in the pic?  I think you can tuck it in, but it'll get really close.
How can you tell the Kumho race tire is wider?

RETed

Yeah, they should fit no problem.
If you don't like the stagger, don't worry about it.
Enjoy your tires and wheels.
If you're worried about the "flush" look, you can run a small spacer in the rears to push them out with the fender line.

Drops like that do not normall affect clearances that much.
If anything. camber adjustment (i.e. front camber plates) will allow you a little more clearances up front.


-Ted

RETed

No, they will not fit with anything larger than a 215 wide tire up front.

Looking at the spec's on tirerack.com, most of the kumho's sect. width and tread width is bigger.

For example, with the Kumho Victoracer (not the same tire as show in the pics) it is 11.1 sect width and 10.3" tread width for the 275/40/17 tire.

While the a street tire such as BFGoodrich g-Force T/A KD, has a sect width of 10.9" and tread width of 8.9"

I asked the kid that is running the 27offset on the 17X9, he said he checked it and no rubbing, he's also running a 5mm spacer in front. He'll be racing on them this sunday, so I guess that will be the real test. According the webpage using the 17X9 w/ 27 offset

The clearance from stut housing to the inside of the wheel will be 12mm LESS
The outside edge of the wheel will EXTEND an extra 38mm

How much room is availible on the inside, since I would think this is key to making something like this work, without widebody fenders.

I can see why you are recommending the +35-40 offset as it bring the wheel even closer inside caliper and makes it stick out less, if this were the case, I dont understand why someone wouldn't have already tried this and we would all be rejoicing in running 275's in front (which everyone says is impossible on stock bodywork) Which doesn't seem possible if you are saying there's only 5mm more room on the stock FC wheel.

And finally, Spacers, basically I could run the risk of trying a 35 offset like you said, and if it doesnt work and rubs the inside, I cuold run spacers correct? Just so I'm not totally screwed. He person running the 27offset 17X9's is currently running a 5mm spacer in front just to make sure they dont rub. So I'm guess that a 30 or 40 offset would be too far in. Couldn't I just mount a wheel on an FC and measure how much space is on the inside using a stock TII wheel? then I could calc a new offset and how much closer it would be, plus I'd have to turn the wheel etc and measure again.

The other factor I'm seeing is lowering, I'll have coilovers, but it will not be excessivly lowered. I'm thinking maybe 1" from stock.

Thanks for the replies ted, that was exactly what i wanted to know

RETed

The section width is only 0.2" difference, and that's not too bad - maybe 5mm.  Concentrate on the section width, as this is what hits the insides.  The tread width is typically narrower.


Getting it to tuck up front is next to impossible.  We can easily fit 225's up front...and maybe 235's.  Some have been able to get 245's to fit up front, by anything wider is very hard...under the stock fenders.


Up front it's tight - maybe 5mm or so.
In the rears, there's a lot of space.  Easily there's almost an inch inside and a couple inches to the outside fender line.

I don't think it's possible to fit a 275 up front.


Sure, this is how I am able to give out recommendations on safe sizing.
Running a small spacer (5mm or thinner) is not that big of a deal.

SoloIIdrift

Thanks for the response Ted. Do you think it's possible to run 285's in the rear with the perfect offset?

RETed

275 is already tight enough, I would worry about 285's.

How about this setup?

17x7, 225/45, +40 offset

btw, it's for front and rear

SoloIIdrift

Ok, last one I promise.

17X9 front 35 offset 255/40/17 tire with spacers of ? mm's

17X9.5 38 offset 275/40/17 no spacers.

I'd roll the fenders as much as possible, and i know the front will stick out a little bit, but I'm thinking it can't be worse than the pic I posted above with the guy running 17X9's w/27mm offset + 5mm spacer w/ 275's in front, right??

domesttuner:

It'll work but please read the thread before you post... it has been mentioned before.

SoloIIdrift:

There is no way 255s are fitting up front as far as I know without overfenders of some kind... in the rear, 265 is pushing it even with right offset, and I think your offset is already too tight. So those won't work without serious modifications to your fender AND spacers.

domesttuner

i did read the entire thread, but everything i read said that +40 would be very close. i couldn't find what i needed easily.

thanks for the info, though!

Rookie84

oo I see Stock TII wheels are 16X7 +40mm and people don't have problem fitting 225s up front and back with them. Hell, I have 245s in the back on stock TII rims

domesttuner

yeah, i thought 40 would be okay since that is stock for TII's, but i knew those wheels were 16", and i just wanted to make sure 17"s would still be okay.

what size tires do you suggest for that size 17x7

i was thinking 225/45

what do you think?

Rookie84

225/45 is perfect. In fact, it is the widest tire that will fit on 7" wide wheels perfectly and will not hinder handling. I would not have 245 in the back if the previous owner didn't put them on because it's way too wide for 7" wheel.

fstrnyou

me too

domesttuner

great, thank you very much!

that's what i have on my old buick, but that was FWD and the wheels were designed for it, so rubbing wasn't an issue. thanks for your help!
