35's Tyre conversion

[double_d69 Member Find all posts View Profile Close double_d69]

Guys I'm going to put some 35's on

I've only seen this done on the Artic Trucks and so far the biggest problem I have seen is getting flares made to cover the wider wheel base. I'm currently investigating this at the moment and getting pricing.

My steps will be this

1. Change diff ratio from 3.73 to 4.10 or 4.56 (the latter is much cheaper therefore I will most likely use this)
2. Trim fenders to fit 35's - I want to make sure I can still flex....at least in the rear anyway!
3. Install custom flares to cover wheels
4. HD Spings - Perhaps I could remove the front sway bar to gain a little more travel and not sacrifice the onroad handling with the HD springs??
5. Go and find some mud and test them out :mrgreen:

As far as costs go

1. 4.56 diff gears can be imported from the states for $2000 (includes front and rear ring and pinions, rear pinion flange, rear solid pinion spacer ,mini installation kits and 5hours local labour to fit).
2. Flares - unknown as yet
3. 35's (315x75R16) - Most likely MTZ's or BFG KM2's on a set of Dymanic rims 0 offset - $2500 or i may buy second hand
4. HD Kings - $330

As far as road worthyness it's probably not going to be hehe - might try and get an engineering cert??

Feedback welcome!

Re: 35's Tyre conversion

Feedback - buy a 100 series or GU and fit 35's to it

Re: 35's Tyre conversion

The body mount at the rear of the wheel well is gonna spoil your plans. 35's won't fit without a cut and shut on it. You'd also need extended bump stops.

Can't speak for the other states, but in SA this would be difficult to engineer, if not impossible. The engineer would want a brake upgrade for this much of an increase and also they'd want the sway bar left on (Which would need mods to stop rubbing aswell).

Any rubbing on any body work or suspension components is an automatic "Can't be engineered"

I think (and it's only my opinion of course) you should consult with an automotive engineer before spending any money.
No engineering certificate = unroadworthy = void insurance.

35's would be police bait in SA... since our "Hoon" laws came in our coppers seem more educated in all things automotive.

Exactly why I got rid of my weekender, body lift and 35's = police bait http://blkmav.com/

Re: 35's Tyre conversion

I have been in discussions with Arctic trucks and they WILL ship a kit over to be installed locally. As for getting an engineers on it, well, thats gonna be expensive...

Any ideas on pricing for this?

The whole thing could be getting too expensive by the sounds of things..... as nice as the 35's would be, maybe I just stick with my original plans of 33's

Thanks for the feedback

Re: 35's Tyre conversion

Factor in GST & Conversion rates it wont be cheap. but neither will be trying to fit 35's. You will need to move the front diff forward and dropped, lots of engineering... 33's are fine for most.

Re: 35's Tyre conversion

I have 35's on my FJ Cruiser (same platform as the 120). I have had nothing but problems since going with them. Yupu will need to cut the body mounts behind the front wheels due to rubbing, I have blown a rear diff, rear locker, front steering rack, my steering wheel is loose and won't center with an alignment, and have serious vibration issues that Road Forcing can't even fix, I have body cracks due to the wheels 'bottoming out' in the wheel wells, and have an 'odometer error' that will follow the vin number effecting the resale forever.

Once these Tyrese wear down I'm going back to 33's to make the truck more manageable.

Yeah too much work... :cry:

So no probs fitting the 33's?.... i was thinking of some 16x8 dynamic rims with +15 offset - they may stick out a bit from the flares, but should clear the upper arm?

Thanks Ben, you have definately convinced me not to go 35's!! Did you have any issues with 33's?

Re: 35's Tyre conversion

I also forgot to mention I had to replace my front transfer case seals, both tie rods, upper control A-Arms bearings, & wheel bearings on the front axle as well.

33's are a good fit. There is some problems that are associated with the weight of tyres. Some clubmates have been going with 255's (also referred to as 'skinnies or 'pizza cutters') as opposed to the 285's. The 255's are close to the OEM weight of the HT's and have the same benefits with footprints even when aired down. They put a lot less stress on the front suspension components and increase fuel mileage.

I have a PDF of the benefits of 'skinnies' from Overland Journal. If you want it PM me your e-mail & I will send it to you.

Re: 35's Tyre conversion

Iīd say 35" are very much ok for 120-series. I canīt understand how Ben is got so much parts worn out/broken... It have to cause of driving style/terrain and lot of miles.

My friend has Arctic Truck version of 120-series, I have droven with it too. Itīs very sophisticated truck and goes well at any speed. Good suspension, not too stiff but handles itīs job well.
There is 60 mm body blocks under, the ones behind the front wheels and the most back ones, are custom made; there is no blocks between, only OEM rubber. Itīs 206 cm wide, wheel offset is -52 mm.



This is his AT35 Hilux (only 20 mm bodylift + 120-series front struts + Some fender arch trimming/flares):


Some other pictures of 120-series with 35" tires. This one is with 40 mm bodylift, 70 mm suspension lift, 8x17" wheels offset +10 and 35x12.50R17 tires.







Compared to stock:


33x12.50R17 are much easier to get fit. Youīd need 75 mm bodylift, spacer rings below the lower front spring plates (stock springs), front mud flaps off and itīs it. Wheels offset +10 and you donīt need any extra flares. Stock gearings are fine with 33" too. I have seen more than 10 of these, made by local offroad shop. I can highly recommend.

This one has 75 mm bodylift + some suspension lift too. And 33x12.50R17 tires. Looks good too.

Re: 35's Tyre conversion

Thanks for the pics and info - some very nice trucks

I do a lot of 4x4ing and sometimes really push the limits of the Prado - similar to Ben i guess, so the 35's would be too much strain on the axles, cv's and diffs i would imagine. I'm not sure how much those Artic Trucks articulate?? Maybe this is something they don't require as it's all generally flat driving? For me I need all the wheel travel I can get, so a Tyre too big would scrub my guards.

In QLD where I live we are allowed a 50mm body lift so it is something i've considered, however I think there would be alot of work involved - e.g. raising radiator, bull bar, transmission, extending all the lines etc. I was thinking rather than 33x12.5 I would go 285/75R16 as the I would scrub my sway bar with anything wider (unless I had a 0 offset and then I would have problems with the flares). As I understand it 285/75R16 will go on with only a 50mm suspension lift and a -13 offset.

Re: 35's Tyre conversion

Allowed a 50mm body lift and getting it engineered are two very different situations. If you have driver/passenger air bags then you have no chance of getting engineered with a body lift.
