Outer Limits 4x4 Board

hey

pretty much what the title says

im buying another set of tyres for the paj- purely for offroad, im going some mtr's or the like, as i have a set of real good not worn 31 ht's for everyday driving

-my ht's are on zero offset rims (no gap)

i was thinking of getting some l/c rims (20mmish gap) for the tyres to go on, as these will be offroad tyres(some hardcore/mostly touring/dirt roads)

- so does it really make THAT much of a differecne in stress to steering stuff ie wheel bearings for that extra offset.




OR should i go the patrol offset (10mmish) for middle ground

I know nothing of your vehicle.
But my zook has 65mm offset rims.
Have not worn out any more bearings than I did before.
But it is clear that more stresses and worse steering geometry must happen.
Tho I'm happy with mine, some would not be.
My personal (non expert) opinion is a 20mm change should be fine.

I think as an offroad set, it won't affect things all that greatly.
As everyday it may wear them out quicker, but for a weekend set I wouldn't worry about it... Plus the extra width is always welcomed

non professional oppinion is that, yes it will affect bearings, handleing etc to a degree, but not enuf to overcome the benifits of a wider track...

I run 10" rims (tho std toyo backspace). I think the mud and water gets to the bearings before the offset has a chance to affect them.

I agree with that

it all comes down to maintance. just check them more often and maybe regrease them a tad more..


id be more worried about your wheel nuts and studs!

Exactly.

The exact centre of your tyre should be where the wheel "turns" for steering. This line is traced from teh top and bottom swixel points. If it sits outward or inward from this then impacts will load the steering trying to turn the car. More force, more wear, poor handling.

Again, not an expert, but I think IFS vehicles would be a little different, as even with standard offset, the entire wheel sits outside of the pivot point, but it would put more stress on the ball joints, or heim joints as the case may be.

Not that it stopped me putting -25 wheels on my Prado, lol.

enter "steering axis inclination" into Google images and you will see that even though the pivot point appears to be further inboard, the result is exactly the same- the tyre's contact patch is suppoesd to sit just outboard of the steering axis intersection with the ground. Note that IFS cars tend to run more backspacing on their rims to get the correct results with acceptable overall width.

Also note that increased tyre diameter will affect this!

Leverage, bushing compliance etc makes IFS cars more sensitive to correct wheel backspacing/offset.

2 easy

after reading all this- ill be going ahead with the land cruiser offset rims then

cheers

I've had toyo offset on my paj for a while now. I've not noticed any large ill effects.

I believe if your susp/steering components are worn then the extra width may exagerate or amplify the effect of worn components - ie if your steering is sloppy now, the wider offsett will make it worse.

just throw some 33's on some custom massive offset 15 x 10's and be done with it.
If its for offroad only, screw the flares !

paj got width?

My rims I bought second hand were fitted to a pajero, -28 with 33x12.5 claws bloke said it was awesome in the bush

yeah the steering is pretty good any way, all the ball joints and the like are in pretty good nick- i had a good squiz when we had it over the pits at work when we put the 2" lift in.

so yeah probably go mtrs or bighorns or maybe radial claws- just gotta see what the whole coin situation

pajero was awesome in the bush

yeah hulsty i know

I've got reverse offset rims on my 60 and don't really check the bearings as often as I should. If you increase the distance from where the original rim's centre sits to the centre of the hub, you will increase the torque/moment on the bearing. Torque or moment is equal to the force multiplied by the distance of application. Think of it as rachet with a short bar on the end of it and then with a long bar on the end of it, the torque/moment increases dramatically.
If you are aware of what is actually happening to the bearing you'll understand what "may" happen if S!@T goes wrong.

yeah i realise the bending moment will increase,


for that reason ill only go the landcruiser offset 22mm rather than a flipped rim.i wasnt looking for anything extreme rather a bit more width

ive no doubt that it would stress them more.. but ur using them in a crap environment any way, so u will be replacing them as it is.. jsut do it.. u cant beat stability!

Another thing I have noticed that I think someone else has mentioned, is that if you have got a front locker (air locker) and your rims have got a large offset, steering is massively comprimised. If you try and visualize what is happening, the steering setup is trying to drag the wheel over a small radius instead of simply swiveling the wheels on a point.
After all this, I'd still recommend sticking offset rims on any vehicle. there F%^&ing great ! Not only making roll over less likely but also giving you a small amount more wheel travel. Oh, and if you consider buying factory offset rims from Rockcrawler, mine where $150 each.. from Procomp (16 inch, reverse offset).

paj got width?

yeah it does now

MTZ's

and 15x8 cruiser offset sunnies

Looks the goods... more pics

yeah looks good- almost 4wd worthy
