CRX rim Size

[Int3gra-T]

hey guys, i got a 91 CRX, its got stock 14" rims,
if i get 17" rims. will i get any inner rub etc?
or would 16" be more suitable?
help please...

[Sexc86]

gday mate
i had 17s on my civic, as these cars are very similar i should be able to relate, and yes i did get some scrubbing on full locks, but all depends on type width and profile. depends what your aiming for as well with the rims, if your after looks, id say 17s, if your more after perforamce and a bit of looks id say 16s... just my opinion .. good luck

[Int3gra-T]

thanks man, MOD PLEASE CLOSE.

[ITEAZR]

yeah i got 17's on my crx and its lowered and it rubbs...

[bumography]

my 16x7's rub on one side
but i fixed it by raising the car a lil

legal issues? what's stock diameter of a 14" rim+tyre?

[tRipitaka]

my stock diameter size (195/60/14) is 589.6mm

after putting 17's (205/40/17) in, it became 595.8mm

so ~6mm difference, which causes about ~1% change in speed..

[Bayani]

6mm is still within legal confrins isn't it?

6mm is still within legal confrins isn't it?

185/60/14 is the sticker size of stock crx wheels.577.6mm diameter

I got 205/40/17 on now 596.5mm,which is about 18mm bigger than stock diameter

Legal is 15mm bigger than stock diameter of largest optional wheel provided by manufacturer for the series of car (I dont know whether that means if Honda offered an optional alloy wheel at the time u could use that size,does anyone know if they did & what size they were?),so they are 3mm over.u could get away with 205/35/17, at 575mm.

At the end of the day all this is pointless cos your only allowed a 26mm increase in rim width on the front wheels of a FF vehicle.
Stock crx is 5"(unless another optional wheel was offered like I queried above)
So 6" is the max,hard to find 17" x 6" wheels or ive never seen any.

All above is RTA for NSW.

EDIT: i personally will be goin back to 16" when money allows,I found them much more appropriate.

EDIT 2: just found that EF8's came as 195/60/14,wonder if u could argue that to em.

its not so much the rolling diameter that is LEGAL or ILLEGAL.

Its the rim SIZE. Traffic departments allow an increase in 'wheel' diameter of maximum 2 sizes eg; original 14inch - allowed 16inch; original 15 inch - allowed 17inch.

Ive got 17s on my CRX and no rubbing issues what so ever. Even of full lock I don't get anything. I did get inside FW rub on full lock when i pre-fitted 18s - and hence decided to stick with 17s.

I dont know about Perth,but NSW & VIC are all about overall rolling diameter,rim width & also wheel track(which i forgot to mention above,+ 25mm allowed),nothing to do with rim diameter.

I shouldnt imagine other states to be much different,as the overall rolling diameter & combination of rim width/offset is what determines the loadings on the suspension components.

My reply was for Bayani who has a NSW location in any case.

[Bayani]

Thanks CRXer, basically wha I was after ^^ -- Do you have references for this?

Sinister, not having the rolling diamter is odd; because you can still adapt your tyre profile to match your previous wheel diameter.

the 2in rule is a general guide for officers when writing up a ticket; what I want to find out is the more technical information that will allow 17's; as at the moment, that's what I have on my car; when money allows, i'll alkso be going down to 16's.
But in th meantime, I want the car streel legal; perfectly.

[SINISTR]

All of those things get taken into account here in WA (as rest of australia), but wheel size is the most obvious therefore most defects come from wheel size issues - ad as we all know once you chance to a different size wheel you're changing rolling diameter.

Just recently one of the guys here was going over the pits with his CRX and got sent back because of 17inch wheels - yet the difference between the 17s and stock 14s in terms of rolling diameter is 0.23% which is nothing.

what im saying is that the rolling diameter for a stock 14inch CRX wheel eg: 185/65/16 vs a 205/40/17inch wheel - the difference is very small - as I said .23%. from memory it takes a 14inch 1.87175m to do a full rotation while it takes a 17inch 1.87081m to do a full rotation.

So wheel size is the first thing thats being picked on - purely because its an obvious thing. Which 1980/1990 FWD car came out with 17s as stock wheels? so when you get pulled up for a check - if they notice you got 17s they automatically know its 3 sizes over as most cars in those days came out with 14s standard.

[CRXer]

u would have to find the 17" x 6" rim to make it legal,unless there was a 14" x 6" offered by Honda as an option in which u could go 17" x 7", & a tyre limiting the rolling diameter to 593.6 mm(unless u could use the EF8 size 195/60/14,589.5mm which would make a 604.5mm legal).

EDIT: as i always forget,offset would have to limit the wheel track increase to 25mm also.

I understand what your saying,but Im sure if u had all the appropriate info & calculations to throw back at the copper(nicely of course) & your wheels were actually legal,there is not much they could do & the defect would be cleared at the inspection station in any case if they did refer u to one.

[SINISTR]

I don't think info and calculations would make much diff if the copper is set on giving you a defect, Ive seen cars getting defected regardless when a file of permits and notes was given - the yellow still went on for something completly different.

I think in WA you can get defected for just 1 thing not right on your car and surely they will find 'something'

RE: wheels and sizes - i've been pulled over for an RBT couple times and funnily enuf the comment I got about my wheels wasn't reg so much the size but more the look 'nice wheels - are they 17s?' and thats all i got :P lucky i guess.

[Bayani]

Very ^^
Okay, so in terms of an ed9; what're we looking at for tyre profiles on an 17" for legalities? in NSW -- not so much width..
