Front Wheels look bigger than back
 
1 Attachment(s)
first and most of all, I must apologize if my post is not done correctly, firt time ever posting anything anywhere.

to the point, I just had 20" 8.5 front (245/35/20) and 20" 10 back (275/30/20) Savini BM4. for some odd reason, I'm not sure if its just me but it seems that the back wheels/tire look smaller than the front. anyone has experienced this before and is there a quick not costly fix?

thank you all for your quick response.

Front Wheels look bigger than back
 
It's hard to tell what you mean from the picture but if by smaller you mean more sunken in then you can get wheel spacers to push them out a bit. Common ones are H&R and Z1 Motorsports.

theDreamer 01-15-2014 10:07 AM

It is smaller, what you are referring to is offset.
The front push the wheel farther out and become more flush where the rear are sunk in more. Looks like you could put on a spacer in the rear to balance it out.

Never mind you're using an 8.5 wheel up front instead of the 9.5 thats originally used :|

Thank you Zack, much appreciated, I’m referring to the size as in the radius of the wheel, I’m really disappointed on the look. check this other picture

wheee! 01-15-2014 10:31 AM

You are referring to profile height. And yes, there is more sidewall on the front tire. Normal

Tazicon 01-15-2014 10:33 AM

That is wierd that the front tire looks bigger than the rear.

yoshi1975 01-15-2014 10:41 AM

thank you all for your response, I know the pictures are not that clear but it seems that all the replies point to spacers, is just that as soon as someone sees the car the first thing that comes out is “hey, front wheels bigger than the back?” :mad: thank you guys, much appreciated. i hope the spacers fix this look or i'm in deep pocket trouble

Tazicon

you see the difference i'm referring to?

cooltoy 01-15-2014 11:03 AM

The front diameter of you set up is 680 mm, the rear is 674 mm. So you are right the rear is smaller in diameter.

how can this be fix so that it looks normal? i mean, i sse other 370z with 20" and they look normal? i been told about spacers but spacers wont change the diameter of the rear wheel... :eek:

cooltoy 01-15-2014 11:17 AM

You are correct, spacers will not change the diameter. Only tires will. Should have done your math before buying them.

285/35/20 will give you 708 mm.
275/35/20 will give you 700 mm.
285/30/20 will give you 680 mm.

Spacers won't fix what you are seeing. The front tires will still look bigger.

And yes I see exactly what you see. Only fix is larger rear tires or smaller fronts.

yoshi1975 01-15-2014 11:41 AM

thank you All for your input... i hope the shop where i got them from are willing to change the rear tires to bigger size... i just got them yesterday.

Cootoy, you would think the shop where i bought them from would know what they are doing, i mean, you would think they are the expert, i hope they do something about it since i just got them yesterday or else i'm S.O.L :owned:

Yes, they're sunken in. Get spacers :iagree:

cooltoy 01-15-2014 11:59 AM

Never trust anyone, very few people give a crap.

Always double check everything yourself.

They should be able to exchange your tires after one day.

The assumption we are making here is that the tire you bought is available in the size you want.

Different problem, but ya they will look better with spacers.

What are the offsets on your rims right now? I can figure out the size spacers you need to make the depth look even. Will not help you with the diameter of course.

i'm not too sure about the offset Cooltoy, but as you say, it wont make a difference, it will still look smaller than the front, i will go to the shop tomorrow since the guy who sold them to me is off today, i really hope they can change the tires... this is stressful!!! :shakes head:

cooltoy 01-15-2014 12:07 PM

The offsets should be marked on the rim (probably on the inside).

What kind are they?

Are you lowered or going to lower the car?

Falken Azenis FR453... i couldnt find the offset...

again, Thank you Cooltoy for taking the time...

cooltoy 01-15-2014 01:01 PM

Sorry, I meant - what kind of wheel.

ituan 01-15-2014 01:06 PM

the concave face is what you're talking about, i'm assuming. because the rears have a lower offset thereby giving you a concave face, it will look slightly smaller. unfortunately thats how it'll look.

ah sorry, 20" Savini BM4 wheels and car is not lowered just yet but i will be doing that next...

cooltoy 01-15-2014 01:13 PM

Your tire is available in 285/30/20, which will make you overall diameter the same as the front. That is your only other choice for the rears. Or get a smaller tire for the front.

here you go, found the name, Savini Black Di Forza BM4 BM-4 Titanium (Concave) i will see if the shop is kind enough to replace the ones i have for the ones you are suggesting, 285/30/20 so that at least it looks even...

cooltoy 01-15-2014 01:18 PM

Keep in mind that stock sport set up the front is 679 mm and the rear is 675 mm. So even stock it is not the same.

but on the stock wheels you dont see that much of a difference as you can see on these aftermarket ones, do you suggest i try to see if the shop upgrades the rear wheels only to 285 or 275/35/20? would that make a big difference?

thanks Cooltoy, appreciate the education here... :tup:

cooltoy 01-15-2014 01:39 PM

Looks like the wheel come in custom offsets. Front from +15 to +50, rear +25 to +50.

You sort of need to know what you bought. Somebody along the line has that info.

Yah, 14 mm difference now vs 4 mm with stock. I would probably go with 285/30/20. That gets you closer to stock numbers. But if you want to fill more of the gap, then you need to change the front to a larger diameter.

That is why I asked if you are lowered or plan to lower.

he said that the offset on the wheels was 15, what difference will this do CoolToy?! whats your advise? try to get bigger tire? i know i cant change wheels for sure, even the tires might give me hard time, but i mean, they should know this things!! :shakes head::shakes head: your suggestion please

See if they'll replace the tire with a 285/30/20 and then after the drop you can measure your clearance to decide how much spacer you need.

cooltoy 01-15-2014 01:59 PM

Yes, since offset and tire size are two different things, deal with them one at at time.

Get the tire changed first.

Second, find out the exact offsets in the front and the back (maybe you can see then on the inside of the wheel when they take them off).

Once you know the offsets, we can advise on spacer size. With out the offsets it's a guessing game.

it's your offset. you got it wrong. will fix it by adding a 10mm on the rear probably.

come on yoshi, you're japanese, no? you should know this. :shakes head: :icon17: ;)

+1 for an 8.5" front that doesn't look that bad

I would just keep your rear tires and switch to 245-30-20's in the front

From the pics you provided it's not that sunken in the front so worst case don't get spacers until you see how it looks with different front tires.

hahaha... not japanese but for sure Z fanatic...

finally, the shop has been nice enough to take my tires back and will be getting me 285/30/20, so this should make a difference, no?!? :eek:

this forum dealio its awesome, better than an encyclopedia!!! after i get this tires swap, i will come back to ask for lowering education 101... but thinking on 1.0" front and .5" back...

cooltoy 01-16-2014 11:06 AM

That's why you need the offsets. When you lower, the top of the wheels will tuck in more, so you might need larger spacers vs non-lowered. Read the spacer 101 sticky.

MacLean 01-16-2014 11:31 AM

Why did you go with 20" 8.5 front (245/35/20) and 20" 10 back (275/30/20)? Be honest with you, I would have went 20x9.5 (265/35) & 20x11 (315/30). I wouldn't go any smaller than 305 in the rear. You want the tires to look nasty and aggressive looking, but still sexy looking as well. Given your 20x10 size I would recommend going to 295/30 at least if not 305/30.
