Mud tyre circa 35" to fit on standard Nissan steel split rims

Guys, when my 32" goodyears MT's wear out I want to run larger diameter tyres on the GQ now it has the chev conversion. I have a 2-3" nominal lift in it. I don't want to have to carve the guards out to run larger tyres, so was toying with the idea of fitting a set of 'high profile/aggressive muddies' to the standard factory split rims - i have 5 rims that have a clapped out set of SIMEX ST10 rock tyres on them - great tyre below 10km/hr - nightmare above 11km/hr and noisy/ no grip in the wet on bitumen - these are 750R16 10 and 12 ply cross-ply.

So my ideal set-up would be the larger diameter muddies that don't require guard mods, mounted to the 16" rims, them mount up 33"x10.5R15 All terrains for general use on the rims fitted with the Goodyear MT's..

I also have a spare set of original Nissan white spoke wheels fitted up with near new/low klm 31/10/15 desert duellers but they are perished from sitting in the backyard without storage and not worth the risk, so i could use these rims also.

I realise that 33" is my legal diameter threshold, but am willing to take the risk with 35" or equivalents as long as no gueard mods.

Tyre recommendations pls would be appreciated.

Fit drop boxes to push the front diff forward 10mm or use spacers if you already have caster correction. (I have a brand new set of spacers I'd sell of your keen) a very very slight trim or bend of the rear bottom of the front guards is what I would do. Not trim even, just re-bend. Get rid of the splits, they are terrible and hard to balance and keep balanced. Go to 16x8s and fit some 315/75r16 Km2. No regrets, you will have these tyres for the next 5 years plus so don't compromise.

Check the manufacture date on the "near new" duallers if they are not worn much but you have had them a long time.

Thanks Darren. Can you bring the spacers to the Donk party? You can run me thru the installation then. How much do you want for the spacers as I do have castor correction bushes fitted.

I believe you'll still need to chop the GQ rear too Phil. Check out AB's & Rossco's at the meetup, a bloke in Lilydale did it for them and it looks full factory, price was right too!

I would really like to avoid the panel chop, so is it the width of the tyre or the diameter that is the issue? Also, is this guy recommended for the bonnet grills I want to insert re airflow? I have the grills but need them colour matched and the bonnet cut in two places. This is not a job for a butcher like me!

Best to chat with the GQ blokes Phil for the tyre scrub issues. In regards the panel bloke, reckon he could do it all and he rolls the edges after chop too I believe mate.

At a best guess, I'd say the height of any 35 would scrub the GQ inner guard above the chassis at full flex so offset is needed and the chop and rubber flares added thereafter. AB and Rossco are running 35x12.5/15 Km2s though not pizza cutters that may have a slim chance, pardon the pun!

My suspension is relatively stiff, certainly can't flex like others I have seen on the forum, so if I could get a tyre that fits inside the guard and is 35" diameter I would be happy. I take on board Darren's comments regards split rim balancing as I used these rims for years with the sines tyres, wobbled and bounced around, but a radial tyre would not do this as badly as a cross ply, certainly since the dimes are 12 ply and with 5 psi still stood upright!

AB do you have the contact details for the panel chop guy, assume he is a panel shop?

The 35s will fit inside the rear guards of a GQ but scrub the inner upper of the wheel arch, this is smith so there is no damage. Call it a bump stop.

If you have fitted longer lower trailing arms though then cutting the guard will be required.

I will bring the radius spacers with me to ABs. I will check what I paid for them and let you know a price mate.

Do you have front mud flaps? They need to go. I could bring my folding claps and if we feel energetic fold the back of the front guards while we are there. It's pretty easy to do..

Do those silverstone centipede copies come in a 34" x 9" x 16" ?
Not a fan of split rims,

Sorry mate he was leasing out our mechanics spare factory for that time and now he's working full time somewhere.

A decent metal fabricator should do it easy!


Heat and roll...

Just some food for thought too Phil mate. I looked at/queried some unusual new tyre/rim sizes when I joined the forum and was kindly alerted to the fact by blokes like Darren that emergency spares would be weeks time to find out there and sharing extra spares between a convoy (no matter how small) was a great idea :-) ! A lot of the Vic adventuring crew seem to berunning 35-15/315-16 within mm's of each other to get everybody
EDIT: back to camp!

OK, this makes sense. Thanks guys for the input.

Darren, I will take the spacers, but right now will sit on the fence regards body mods until I see first hand what it looks like. I still have a lot of life in the 32" tyres, so can afford the time to consider further, however will likely end up with the 35" solution.

TD, maybe a bit too aggressive and unsure how they track on wet bitumen. I have a heavy vehicle and the lugs will 'melt' under the load I reckon and give a very short life, but I have looked at them as well.

Check out this thread. Doing the back of the front guards will be a fare bit neater than the pics here as I going to paint so I didn't care

Thanks Darren, images don't show up on my work computer - might be an internal issue, so will look tonight at home.

I'm out on this process. There is no way I will attack my vehicle like that, despite it turning out how you wanted it, it just sends shudders down my spine! I then have ask, what is the largest tyre that will fit under the guards on a patrol with 2" lift? - 33"? 34"? but not 24"?

Don't stress Phil, Daz has already kindly offered to do it for you FOC at AB's donk party soon mate! We'll just get you pissed and facing the other way whilst he preps it so you can join him on one of his 37" Otway muddin winch challenges :-)

You know, the OTWAYS is the one place in the world I am not returning to to go 4wd'ing. I was on a Landcruiser Club trip years ago and they managed to get 5 vehicles stuck up to the door handles in some black sandy goop down the bottom of the valley of death and it pissed down all night, despite being 40 deg during the day. We got the last guy out at 7pm the following night after having to drive 100klm to get to the other side of the bog - total nightmare of a weekend. I think I would rather contemplate a weekend at Jells Park than that - sorry Darren, just a huge recovery scar that has blown up after MB picked it!!!!

@PBBIZ2 we must know each other as I was in tlccv for years.
Good friend of tony Bryant and dave white. Think I remember stories of that trip.
Anyway have you thought aout putting a body lift on the GQ ??

No but will it help? I have never considered it to be honest, am unsure about legality, bearing in mind I have spent a small fortune getting thru the VASS process.

I believe in Vic we are allowed a total max of 75mm/under 3" total axle to guard lift from stock (happy to be corrected though). You've already got a 2" sus lift too I believe so maybe 1" body lift could over max it. 35's are definitely a no no unless engineered with Portals too I believe. I'd also imagine a 33" tyre would be your GQ max legal. I'm assuming stock GQ's of your vintage were 31" or maybe under like 30" so worth checking that too. Two tyre sizes up max I think?

Oh dear, looks like more time in exile. Portals are a major shift in my thinking, but possible - not this year but by the time the 32's are knackered, for sure. I am open to weigh up anything to be honest and if it makes total sense, its on.

You miht have to make room in one of your paddocks MB in case exile becomes Xmas Hills.

Happy to rob a b&nk together tonight Phil and camp out in exile together in front of:

These really are the ducks guts I reckon and I have no need for them but have always wanted'em. Fitted they look like circa 24k with the replacement GU axle housings, hydro brake boost and engineers. Seems like an expensive way to legally run 35" tyres, but the GVM also goes thru the roof as well.

Yes, gotta have.

Level me out a spot big enough for the patrol pls, maybe big enough for 2?
