can I fit 245/35/18's on all four corners of my zed (NA)

Well after all that

I've looked and looked and found very few tyres 345/35/18. Imostly want them for the fat look, It also allows tyre rotations. Thanks for all the replies. I think for the next set of rubber I will try and find some 245/35's.

 

The correct term >>

that Ian doesn't seem to be aware of, is Rim Offset.
There's nothing wrong with the "Rim Design", it just wasn't designed to fit to your car or application.
Do a search in the tech section, & you will see that it mentions that when purchasing rims, to specifically get rims with the right/correct offset. These will clear the calipers without any problems.
I agree with the others on here that have stated, "NOT TO GRIND YOUR CALIPERS". Thats like someone telling you to put oil on your tyres so you can smoke them up. Not a bright idea. They were designed & went through rigorous testing by Qualified Engineers when manufactured. They weren't designed to be modified by reducing their size.

Answer to not that dump a question

Backspacing
Also called rear spacing. Distance from extreme back edge of the rim, not bead seat, to the mounting pad. See Illustration. Lay a straight edge across the back of the rim and measure down to the mounting pad. Nearly all custom wheels use this measurement method to indicate the location of the mounting pad in relation to the rim.

I got P36 on the ROH Drift R's
as in a 36 positive offset
30's wont clear caliper's
36's or 40's will depending on arc in spokes too, if any ?
But that's specific to the ROH Drift R Rim's

 

It isn't a fault, it is probably because you purchased a 'low disc' type ri

m and not a medium or high type disc rim. See the work meister website for details if you need more info on that.

 

To quote you Ian, "Its not often your right", this is another example >>

Where do you come up with this BS. "NOT Rim Offset"
Check any reputable wheel designer or tyre store & you'll see that all New Rims (as opposed to 2nd hand) come with a sticker on the rim with the centre offset of that particular rim.:thumbsup:
If you buy the wrong rim & it scrapes the caliper, then the designs not at fault, YOU ARE, for not asking for the correct offset to clear the calipers.:embarrassed:
Most Tyre & Rim retailers will tell you what fits, their the experts. If you go against their advise & buy something that looks good, but doesn't fit, your the goose.:thumbsdown:

it isn't just the offset that determines calliper clearance, it is the disc

type.

 

I certainly hope rims don't move in relation to the caliper

If you have 2mm clearance between the rim and caliper when the car is just sitting there then not matter what corner you are turning into the rim will not tilt or flex over to hit the caliper.

Btw I've filed my calipers smooth so start the flame war

 

Offset is not an indicator of caliper clearance

for example my front wheels have an offset of +41 yet they clear the calipers by 18mm, that's almost 2cm which is a huge clearance! Yet other wheels with the same offset might not clear the caliper.

This is because of the High Disc rating & design of the centre piece. As Method was saying there are different classifications for brake caliper clearances on wheels. However, some cheaper wheels many not provide this information.

 

I keep telling you KEZA there's NO second prize :wacko:

Rim offset has NOTHING to do with caliper clearance. Rim offset is the relationship between the rim (bead to bead) and the hub face. If you have the incorrect offset then your tyre (or wheel if you have undersize tyres) will rub either the inner guard or the suspension.

The design of the wheel is the determining factor on whether the calipers will scrub.

High caliper clearance wheels will have a deeper arch in the spokes between the hub face and the rim, effectively skirting around the body of the caliper.

Low caliper clearance wheels are more likely to have straight (or very close to it) spokes between the hub face and the rim rendering them useless on a car with larger style calipers (unless you fit a spacer).

That is why 3 piece wheels are so popular. You start with the appropriate centre (high or low caliper clearance) and then proceed to fit an inner & outer rim to provide the required offset. No matter what offset you end up with you CANNOT hit the caliper because the design of the wheel already precludes it.:thumbsup:

 

Thanks Loyde, The rims are at Gould St Chullora getting machined

Btw the rims are SUV/truck rims and they start from 20"+ They are beautiful and i havnt seen many zeds with 20"...just want to be a little different and unique ya know? :zlove:

 

ive got 255/40/17 on the back and 235/45/17 on the front..

i get no rub dont know if that helps..?
Cheers

 

Re; Caliper woes

I think you need to re-read the thread Bro, this discussion is about rims that rub on the tops of calipers, NOT about wheels centres that rub on the "NISSAN" embossed caliper face.
Offset plays no real part in the cause of the aforementioned problem.

 

Tyres

Yes buddy. They will fit without a problem. In a nut shell, the back can go upto 285/40 ZR 18 or 17. The front though you have to be careful. To be on the best side, don't go anything beyond 245 size. If you go above that size, it may hit the upper arm of the suspension arm, and also the car will begin to 'tramline' as the tyres are so wide. Best bet is to stick to these sizes. I have tried the tyres with various sizes before buying and best suit the car is as wide as you want at the back and then sticking to the size I have suggested at the front. I have an N/A with me as well, so I'm giving you the best advice as I could. Good luck champ

Get the back as wide as you like keeping cost in mind and stick to the size I gave you for the front.

 

Rims are incorrect for car

Hey guys, just in reply to this posting. There's gotta be something wrong with the rims in that case. I just got a set of calipers and rotors for my zed as the brakes seem to fail on me with I go out for my weekend drives, and the new rotors in my car are 13inch and I have 17" rims on my car and it clears perfectly. It's been said that when putting in the bigger calipers and rotors that you have to have a minimum of 17" size rims on the car. Dude, if the rims are bigger on your car, and it's touching, then there's something wrong. The type I got for my car were the R34 GTR calipers and rotors for the front. So they are big in comparison to the stock Zed calipers. Hope this helps.

Good luck

 

thankyou najay thats the most straght forward informative answer yet.

 

Me Bad :embarrassed:>>

eyes checked, brain in gear.:LOL:
Didn't see that bit, about rubbing on the Tops of the calipers, only the bit about grinding away the raised NISSAN on the sides.
Still with 20" rims, he's goner need Very Low Profile tyres, just to clear the inner guards etc.
Cheers

what is rong with grinding

ive ground the nissan off the brakes before and had no problems i dont see how grinding this off is going to make the calipers leak unless you hack at it and it cracks ,some of you guys are way to anal about this stuff. i herd a guy thats been selling imports for years tell a guy just to let it grind down (this one was only cliping the brake when cornering, sounds dodge at first but when you think about it theres nothing rong with it , its a chunk of aluminium

 

I don't think anyone said that grinding Nissan off will make it leak....

the anguish was created when aK wanted to start grinding the top of the caliper. Obviously there is a lot of meat in a caliper that could probably be ground off without ill effect but how much is too much ? I think finding wheels that WILL fit the zed would be the better solution.

 

You may be happy with a stationary lump of alloy/cast iron.........

slamming into your spokes at high speed, but I can assure you I AM NOT!
Please send a detailed itiniery of your planned travel, as I would like to avoid the possibility of meeting you by accident.:wacko::wacko:

 

The NISSAN can be shaved off a few mm no problem...

I don't see what the big deal is? My wheels only just clean the front calipers bay few mm!!! Anyone who has seen them can vouch.
