finally found a wheel i'm in love with. It's 19x8.5. the stock 17's on my KJ are only 7" wide, and it seams there isn't much space for anyhting more than 8". Does anyone know or has 8.5 on their car and would be able to tell me if they can fit without rubbing.
cheers.

Yes, 8.5" wide tyres can fit without rubbing. (providing you dont really chuck on rubber with bigger than 235 width). 225/235 rubber is standard for members running 8.5" rims.

nope got 8.5" on mine and its fat fat fat :D

just try em on first coz mine stick out a weeeeeeeeeeeeee lil bit. not much and not many can notice it but its sticking out a lil bit. dosnt really matter its just that u cant slam your car heap on the front but the rears will be fine.

booya had 17x9s for a while, it all depends on the offset

Should be ok and like it has been said, as long as you have the right offset and tyre (nothing bigger than a 235)

I had 245s on 8" wide rims and they were rubbing against the suspension control arms :confused: But this can be fixed by putting on some magna sports/vrx control arms

BTW, What rims are you getting?

As long as the offset is correct and the size of the tyre does not exceed 235, everything
should be fine. The width of the tyre together with the offset is the limiting factor.

Basing one the stock 225/50R17 with 17x7" wheel with +46mm offset:

If you use 235/35R19 tyres with the 19x8.5 wheel with +40mm offset then the amount of
room between the tyres and suspension components remain the same as stock. However,
it will stick out 11mm further. This may cause rubbing of the splash guards during turning.

If the wheels have a +46mm offset then the tyres will be 5mm closer to the suspension
components and will also stick out 5mm further. This is the ideal setup.

The best setup will be with 225/40R19 with the wheel having a +46m offset then it is the
same as the stock in all dimensions.

I have 235*40 R 18*9inch ROH DRIFT R'S and havnt had a problem at all know rubbing whatsoever! FATT!

Do yourself a favour don't use fully-sick-dorifto underzised rubber. For 8.5" you should be looking at 245mm rubber. if you can't fit properly sized rubber, then find some smaller rims, the hassles of under-sized rubber can be a nigtmare.

Problem with the is that the tyres offer no protection to the wheels if and when you
accidentally scrape along or hit the kerb.

attached are a few sizes: the left one is MYMAGS', the middle one is the best fit and the
right one is the next size wider one.

AHHH thats why i scraped the front left!! is it possible to get the 235*35 would it make any differance to rim protection if it was still 9 inch?:confused:

No, you need wider tyre not even lower profile tyres. As Chisholm said, you need at least
245 tyres with flange protection.

9" = 228.6 mm (thats the width of the mounting surface, so the total width of a rim,
including the lip will in most cases add another half inch which makes it 241.3mm.

Thanks for the info vlad i'l have to upgrade to the 245's then:)

I will be running 255's on a 18x9" rim on the front - 255/35

the back's get a 283/35 on a 18x10" rim (now THATS Phatt!!)

Had 8.5 inch wide rims on my old magna and never had a problem.

Because i went for a 8.5 inch rim, i was able to get one with a big dish so it looked PHAT !!

That's nothing. I saw a wide body 911 with 305 R19 wheels at the rear.

no matter how wide or narrow a rim is a 245 won't fit without changing the rear suspension control arms.

Then the obvious choices are replace/modify the rear control arms, or get a more sensibly-sized rim :)

Although, I'm running 235's, and I still have a bit of room between the tyre and control arm. This makes me thing it may well be possible to squeeze 245s in with the right offset.

finally found a wheel i'm in love with.
Before you get too attached to them, confirm that it's a) insurable and b) roadworthy

thanks for the detailed facts vlad, you sound like a pro, well the stock sports suspension in my KJ is the same as the vrx i believe, i have about a fingers width of space from the control arms to the corner of the tyre, which as u guessed correctly are 225/50 on 17x7 wheels, so lets just say 15mm, from where i'm looking at it i don't have much in the way of goin inwards, just outwards, but it aint going to look good if the wheels stick out further than the body, i'll have to see what The Tyre Factory has to say and what they can do, otherwise it looks like a different, more slimmer 19" rim for me :(

8.5" wide rim with 225mm wide tyre is fine (the middle example of my previous post). Also,
are you measuring that gap with an old tyre or new tyres (bearing in mind theres may be a
difference of 5-7mm of tread from new to old). Also, my AWD rear only has 7mm gap. This
gap, however, if you look at how that suspension arm is attached will move with the wheel
as it is attached to the hub so once there is a gap, that gap won't change. Also, going
10mm further out is not a problem (that is what I have as I maintained the inner gap size)
in going from 215mm to 225mm wide tyres as there is plenty of wheel arch gap to take
care of that (there is approx 15mm gap between the outer face of the tyre and wheel
arch). Just stick with 225/40R19 on the 19x8.5" wheel with a +46mm offset and everything
should be exactly the same as your stock 225/50R17 on 17x7" wheel with a +46mm offset
as again, because the tyre width is the governing dimension, the new tyres sits in the
exact same spot as the old ones.

There are benefits performance wise by running a tyre on it's maximum width rim, that’s part of the reason drifters do it, they provide heaps better feedback as the sidewalls when placed on wider rims provide much better lateral stability, generates less heat because of less movement. It’s a way of getting the benefits of much stiffer sidewalls without having to go to the expense of getting racing tyres. Drawbacks are increased ride harshness and that your rims have little protection from objects hitting them.

With the right offset most ppl i know have had no worries fitting 19 x 8.5” wheels with 245/35/19 tyres.

Something else to consider about wider tyres is that the probability of aquaplaning is increased and wet weather grip is decreased.

Yes, its harder for water to get out. However, ones with wide grooves and directional
tread solves that problem. You don't see F1 cars with wet weather tyres aquaplaning.

i got 8.5" on mine.. and they rub a lil but only full lock... jus on the inside of the gaurds.. nothin to do damage to the rim or the gaurds thoe so shuld b sweet

Actually you probably do but the electronic controls are working overtime :bowrofl:

You know, I've noticed lately that a lot of people say they've experience aquaplaning but after listening to their appraisal of the situation, it sounds purely like typical loss of traction. Yes, aquaplaning is a loss of traction but it's different to normal sliding. It's not normal to suddenlt go aquaplaning off the road.

Anyway, keep your pressures up and reduce your speed and aquaplaning becomes harder to do.

That's why IMO stretching tyres on a road car is a silly idea. From what I've been told, you have to run rather high tyre pressures to avoid the risk of a blowout, which means bone-jarring ride quality, and high chances of cracking/buckling rims on potholes and bumps. This would be compounded by the fact that the the OP's rims in questions are 19"s. meaning rubber-band tyres. And good handleing obviously isn't a priority for the OP, or he wouldn't be looking at stupidly heavy/wide (for a magna) 19x8.5" rims.

Stretching tyes onto wide rims may provide benefits for drift cars, but a street-driven magna is rather far removed.

My new rims (to be fitted tomorrow) will be 19*8.5 running 245's front & 19*9.5 running 265's rear...

Why? Forget about practicality, what happens when you have a puncture? Wider tyres on
the rear for a FWD is very bad for handling, not counting the fact that the extra weight of
the wheels detracts from performance and handling and fuel economy.

And according to wheels master (http://www.wheelsmaster.com/rt_specs.jsp). with 265/35R19 tyres on a 19x9.5 with +40 offset, the
tyres will be 14mm closer to the suspension arms and 26mm further out which makes it
dangerous and illegal. From memory, according to my friends ralliart, there is only about
15mm clearance between the rear tyres and suspension arm and sticking out 26mm means
it is way out of the guards.

I'm running 19 x 8" fronts and 19 x 9.5" rears, the size diff just for looks, actually fills the guards out, would have liked 8.5's on the front but didn't come in that size. I'm running 245/35/19 tyres all round, with 9.5" wide being the widest rim you can put these tyres on, the back has a lot less sidewall flex than the front which is on skinnier rims.

Gives me 25mm track increase at front and 20mm at back.

The car has been engineered like this...

The weight of these Konig Unknown wheels with tyres is 19.9kg front and back, only a few hundered grams between the front 8's and the rear 9.5's, my 17 x 7.5" OZ Racing Superturismo Racing wheels are 19.8kg with 235/45/17 street tyres, bugger all difference!

(The Enkei's that came with the ralliart were 24kg with tyres!)

On street tyres the handling is much more responsive on the 19's...

Why?
It must be a RWD Magna :bowrofl:

And good handleing obviously isn't a priority for the OP, or he wouldn't be looking at stupidly heavy/wide (for a magna) 19x8.5" rims.

lol Considering the original 17" rims weigh 3 kg more and have 225 tyres, compared to the new wheels which will have, 235 width its not that extremely "stupid" is it. True front handling is goin to be slightly sacrificed, but its not enough to notice with casual driving, its not like i'm planning to race it or sumthing, just the occasional fang lol Aftermarket wheels are usually a great deal lighter in weight than the OEM wheels. i was gunning for 8 inch wide but they don't have them in the wheel i want, so trying to find a simular one that does but its hard, i probably should mention that the cars on lovell sports low springs. :) does that make much of a difference? lying about 25mm closer to ground, but they still reaasonably new so probably drop to 30mm...
