Post by GRIMACE »

THREAD TITLE CHANGED :D

Whats the biggest offset reccomended for an 8" rim to gain the most stance possible ? ? ?

255/85s are approx 10.5" wide and 33" tall...... :?

It wont be for too long as I am selling the BFGs in hope of purchasing a set of simexes or maxis crawlers in a wider & taller tread.

They go on 16x7. but will fit 16x8.

also why do you want a 10" for a 11.5 - 12.5" tyre with your next tyres. Stick with at most an 8" rim

OK - I've gotta be pedantic here.

10" is exactly 254mm. A 10" wide tyre on a 10" wide rim - I wouldn't have thought so! As grimbo said, why 10" - something we don't know about?

As a comparison, 31x10.5 typically go on 7" wide rims.

Cheers,

Scott

1. Illegal to fit the tyre to the 10" rim
2. Illegal to run a 10" rim on the road
3. the 10" with the tyre is a bag width dimension, not a tread width dimension. the 255/85-16s will have a tread area probably of 7", and just think of all of that lovely downward facing sidewall just waiting to be punctured
4. It'll break the bead
5. It'll be a major PITA to get a seal on the bead to fit to a 10"" rim

6. Every ET and JT2 over 32" will fit on a street legal 8" rim.

the only reason I was asking is I am gonna be purchasing rims soon, and if i could run the 255 on a 10" rim i was gonna buy 16x10s and then upgrade the tyres but I am gonna get the 15x10s with 100mm offset :? (i think thats the right word).

Now i just gotta find em for the right price :D and wait for the funds to build after I see the final bill for my auto overhaul :cry:

This thread is so funny :D

Can I run a 7.50/16 on a 10" rim??? I like running rims that are too wide so I damage rims, puncture sidewalls and roll tyres off beads.

And to add to this - my truck in my avater to the left is running 285/75/16's (33") on 16x7's. It is better offroad to run the narrowest rim you can, so that you are less likely to damage the rim/sidewall and roll tyres off the bead. What tyres do you want to run? 15" wide???

My aim is to increase my track buy 4" each side (approx) I dont wanna hear illegal this illegal that..... its what I WANNA DO.

Izuzu - my initial question may have been dumb, but its been answered. Your post havnt helped me at all, if you have a problem with ten inch rims thats good to hear, I am running the 255 on my standard Rover rims at the moment but unless i go out and by some 3" wheels spacers for offroad use I am not gonna be as confortable sitting at 45degree side angles. I personally dont like spacers, so getting wider more offset rims is my choice.

I may choose to run a 38" tyre in the future, and I think that the fact that I can fit anything from as small as a 12.5 33" rubber to a 44" 18" wide monster swamper on a 10" rim is extremely appealing to me for the many offroad years to come.


Thanks for the constructive critisisum :D :finger: :D

Why not get some 8" rims and have them offset. My 7s I have had offset as much as i could so i got an extra 2.5" track width per side.

A 10" will not rut a 12.5" tyre nicely as it will stretch the tyre and make it next to impossible to air the tyre down. You will also run a greater risk of sidewall damage.

Also when you ask for advice and people give you some don't then flame them for trying to help. Just because it is not what you want to hear don't make it any less correct or relevant

if you are going to a 44 ( on your rangie, right :shock: ) then buy some new rims. you can get them for around $50 -$100 ea and to get this money you could sell your 8" rims because people will want to buy them.

Buy what is appropriate for the job don't try and second guess what you might do.

Grimbo - I wasnt flaming anyone that actually gave me advice (thank you for all you helpful one can be found down the bottom of this post :D ) and i dont wanna hav a set of 7" go to an 8" and then to a 10" rim if the tens will work for the next tyre option anyways.
Your getting nasty cause i asked a silly question, now your getting nasty cause i wanna run a 10" rim, to gain alot of side slope stability and hopefully run some 36x13.5inch simexes some day :D


Thank you for the information turps, grimbo (first post :D ), bazzle, NJ SWB (many thanks :D ), and slunnie.
Thank you for the funny shit locky & avgas :armsup:

Dude the amount of work + $ you'll be pouring into your driveline to run 38's I reckon another set of rims wouldn't even be a blip on the FARK THIS IS EXPENSIVE radar :D

Just get some 8's heavily offset ;)

OK - to be constructive...

If you want to increase track then a heavily offset narrower wheel will be much better than a wide wheel - because the load will be further out rather than spread over a wider area (even though the outer edge of the tyres are the same).

Rims are a very small expense compared to tyres - the ones you are talking about in the future will be about $400 each and you can usually sell rims for about the price you pay for them (2nd hand).

8" rims (although not manufacturer recommended for some really wide tyres) should do the job for about any wheels you can run on a rangie drivetrain (or even a rangie drivetrain with hilux internals).

To run anything bigger than 36's or 38's on a RR drivetrain (even with hilux axles) would be asking for breakages. And no-matter how wide your track goes, it probably won't compensate for the increased CoG needed for the body lift and spring lift to fit the wheels on.

THANK YOU :armsup:

I was told that it is bad to offset a tyre so much, thats another peice of info that had me thinking I can have the 8"s with 100m offset or the 10"s with the same amount of offset.
I like the tens cause obviosly there gonna get me more stance and I can run a 33 on em for now but not for to long hopefully :)


8inch rims with only a 50mm offset cant be good..... or can it ? ? ?



P.S. I hope i havnt mixed up the words offset and backspacing :oops: ? ? ?

where is the IGNORE POST BUTTON...... :D :finger: :D

Anthony...how will you be covering those..RS flares wont... so there is some custom flares..$$$$ if you want them to look good...

First - YOU must decide...what size tyre am I DEFINATELY going to be running.
Second - YOU then look at wheel width options
Third - YOU can then decide how much offset you require
Forth - YOU pay $$$$ to get them made

Then you need to seriously beef your drivetrain to turn them as well as be strong enough to not break everytime you wheel.

So you need to decide where you are going to spend your limited $$$$ first. Drivetrain or wheels...If wheels then you will not be wheeling until you get drivetrain. Sorta catch 22....wheel your current setup until you break something then beef it up.

RS flares will be almost an inch to short thast were the garden edging comes into play :lol:
I will like to run the current tyres on 8" rims aslong as its ok to offset the rims heaps. And also aslong as the same 8" rim can run a 36x13.5 simex in the future.

At the moment I was just trying to find out what rim would be the best for me and my current tyre or if I was better to get rims for a totally different set of rubber. It seems the idea is to stay with 16" rims and get an 8" wide one heavily offset, I like this idea so long as its cool to have them offset a shitload.


I am still not 100% sure if i have the offset backspacing words used appropriately :rofl: or if i have mixed em up :rofl:

I don't know how to explain what I'm thinking, but here goes!

The wider your rim, the sooner the side load (from a side slope?) will be trying to roll the tyre off the bead. If you have bead locks this may not be such an issue.

Grimbo's comments about sidewall damage are the next thing I'd be concerned about.

If "legal this, legal that" doesn't matter, why the talk about flares? Wear a full-face helmet :D

Flares are for the safety of passer bys. So not to much shit gets flicked up into other peoples windscreens cause we all know how anoyying it can be to get a stone chip on your front window......... and also have mud hit your arm thats dried on the tire and let go when your doin 100ks on da highway (it hurts) :)


So who can answer my question about how much offset i can have on a 8" rim if two inches (approximately 6" stickin out from the bolt pattern) is ok then thats what i will do :D and I will run my 255/85 on that until new tyres are needed :D and that wil give me the extra 100m stance each side, that I would like :)

Im running a similar rim on my 110 2" backspacing 15x8s

I had them custom made for my disco running 35: ets

I now find them to wide for the 110 as the brakes are exposed to rocks and the like when racing

I also cant find flares to fit

They were good on the disco the tyres sticking out protected the body work and I had heaps of stability

no idea if this helps or not, but...

i'm running 15x8s with the max offset that speedywheels can supply, something like -28. i think it works out at 2.5" backspacing but i could be talking out my arse

offset and backspacing are just two different ways of measuring the same thing as far as i know... might be talking out my arse again

either way, i haven't noticed any negatives with the setup - steering isn't much heavier (i'm running 31s), and the extra stability is really noticeable
