Wheels for KZJ90 - Help please

[Shayne]

It's all guesswork from me CAT because try it and see is the only real test but i read and crossed referenced and read again over and over before opting for the 16x10 305's , now all sources said these were a true 33" - but they are not . They may even be a little smaller than the 285's on a 16x8 rim , I personally believe it's because Toyo never intended them to be fitted to a 10 inch wide rim .

By that twisted logic a 285 on a 10" wide rim should - and i repeat should bring it down to a 32" tyre which should fit truck no bother at all .

And to add to your misery all tyre brands tell lies some 37" might actually measure 35 , some 35's are a true 33 when fitted , few if any actually give the true fitted size of the tyres they sell and even when they do they leave us to guess what size wheel it was fitted to when measurements were taken

I doubt you will find a 285 that says it can be fitted to a 10 inch wide rim so your steeping outside of the guidelines if you do go that route but i would do it .

I think your flares are wider than mine .

Cheers Shayne, ok so it is a matter of asking manufacturers if their tyres fit on a 10 inch rim?

Could you have a lower negative offset and then push it out a bit further with some wheel spacers? Or am I getting into dangerous territory there?

Where did you get your wheels Shayne? Your truck is ace by the way mate!

 

[Shayne]

No what i'm saying is tyre manufacturer guidelines can be ignored to a certain extent but if you ask they will say no .

I'm not sure why you would want to go much wider than i have , though i would like to using Total Chaos long travel IFS but silly money for not much gain .

If you did go wider than me you would need new and wider arches , i'm thinking about extending mine . Tyres are Toyo Open Country MT and i will be buying them again and the wheels are Gojo's .

Can I add one to the porn-show?....

Love this photo...

Shayne’s mini-me....

I like this one

I do have a bunch of pics of your truck with the bonnet up and a sad face etc Nick from that entire day we missed because your pram hurt itself going over a bump . Unfortunately im on windows 10 now which is a about 4 times worse than than my very low expectations but i can if i must spend 3 hours looking for and posting them up .

 

[fbnss]

I don't know what you're on about Shayne. I just liked the stance of your truck from that direction.

 

[Shayne]

Tell the truth now it just makes you happy when you see it that you managed to avoid me towing your old bus home doesn't it

 

[fbnss]

That would have been bad!

Ps. I spoke to my mate Helen, she said all the photos were deleted along with that rather amusing video of her and the wasps... ask her.

Believe me I don't want to go any wider than what I have to! I am just unsure what exactly I need to get the tyres where I want them. At the minute if I measure from a spirit level which is running to the outer edge of the flares there is about a 100mm gap before the outer edge of the tyre. I'm going to take it to a local tyre dealer whenever I get a chance and see what they think also.

There's no exact science to it CAT , i took the camera out today to get your pics and ended up driving the kids to macdonalds instead forgetting all about it

My rims are well inside the arches but the tyres bulge a good way past the rim and being a 305 width the tread is at least an inch outside of the arch to .

It sounds ridiculous but the correct way to do it is choose your wheel and tyres then make the truck fit them

I very much doubt the experts at the tyre shop will help beyond advising you to fit the most profitable option for them .

I do hesitate to say 16x10 and 285/75 will fit but but i got 16x8 with a zero offset and 285/75 on originally with no lift at all . There was a fair bit of trimming involved but i managed to keep the front mudflaps (most don't) and hey trimming cost's nothing . It was a long way from perfect and it did rub in places but i could have run the truck that way forever .

I have a vague notion that a suspension lift pushes the front hubs forward a little so having a body lift instead you should expect to lose the mudflaps but a negative offset should if i'm correct solve most of the rubbing issues i had .

It's your money so spend it once , i'm on my third set of 5 brand new wheels which is an expensive way to work out what's possible .

I figure yours is a truck for life so if you accept a coil spacer lift could be added for little cost should your new tyres prove problematic the risks of blind purchase are at least diminished a little .

As i say i'm hesitant to offer this advise but damn i wish i could have found someone to offer it to me when i started out modifying , if only you were nearby , i'd have you around here and we could spend a day swapping wheels .

Just found some old pics 285/75 on zero offset 16x8 rims and no lift at all

Trimming at front mudflaps , i took more away as time went on .

They rubbed on the chassis because they were zero offset

 

[CAT]

I think you have given me enough confidence to go for the 285's and go from there

I have a winch on the way so after fitting that I may find that I do need some sort of suspension lift at the front which would make the 285's fit better.
Cheers lad, will keep you posted.

As promised and better late than never

Top two pics are 16x10 -32 with 305/70 Toyo open Country and the bottom two pics are 16X8 -38 with 285/75 Copper STT OWL which are no longer sold .

 

[CAT]

I ordered a GOJOs 16x8 -32 and it arrived this morning, stuck in on the front and back and it probably has too much of an offset. What do you think? Going to go with the 285/75/r16's on it.

I think I might just go with the triangular 16x8 -25 offset from accessories4x4.ch

 

[Shayne]

The top two pics of tyre and plank have more offset than yours -38 i think and the cooper stt owl tyres are 285/75 . It doesn't make the truck dirty .

Which tyre also comes into play here , what you don't want is square edge tyre that makes the tread the widest part , most available have a curved edge and a narrower centre tread contact area . It's the contact that throws crap up over your doors , and this does happen with my 16x10 wheels hence i wonder about widening the arches .
But it doesn't happen with my 16x8's the tyre wall bulges past the arch , meaning tyres bounce off hedges rather than the arches (protection) but the actual contact tread and so the crap for the most part hits the underside of the arch as its supposed to .

Thinking of going for Goodrich A/T's , now trying to decide between the 285/75r16 or the 275/70's.
Not sure I will get that much more benefit from the 285's? But would it be feesable to put 275's on a 10inch rim? The triangular wheels are 8 inch.

 

[Shayne]

I'm confused are your last pics 16x10 Gojo's ?

If as stated they at 16x8 will a 7mm smaller offset make much difference ?

The above photos are the GoJos 16x10s.

The main difference between the GoJos and the 16x8 triangular ones is the price! Virtually half the cost.

 

[Shayne]

Looking at Goodridge AT the contact surface seem's narrower than on my Toyo's but its anyone's guess how a tyre will sit when fitted , this is the problem with modifying you either copy exactly what someone else did or you throw caution to the wind and experiment so i can't really help further , only you know what you want .
