Volk ZE40X on 2025 GX550 OT

[kulahi]

I’m looking at these wheels and really not doing anything to the suspension except maybe leveling the front. 285/75 R17 (~34s) on +35 offset wheels are generally what’s recommended if not modifying the stock suspension. what’s the biggest recommended tire size in diameter and width on the ZE40X which are available in a 17 +20 offset?

TIA

I was trying to get those wheels(ZE40X) in the 20 offset and pair them with 34x10.5. I thought they looked great and lightweight. However I had really difficult time finding them. Ended it up putting on Tacoma trd pro wheels 18x8.5 20 offset with 275/70r18 tires. Just a touch of poke beyond the fenders. Super happy with it. IMO 20mm offset with stock or sub 34” tires looks great, functional, no mods needed and spare fits.

Good to know 33’s fit. What model year do you have and are you running stock suspension?

2025 OT stock suspension.

I have ZE40X on my GX550, something that no one has mentioned when mounting these is that these are made for M12 studs. Your standard conical lug nuts can only get about 5 turns of engagement and the bore is too small to fit ET lug nuts. I will be installing either extended studs or machining my own custom lug nuts.. but just FYSA

Dang. I have these wheels on order (still 4 months out) and this is not something I considered at all. The bore is listed at 29mm at the wide end and 15mm on the narrow end for the lugs. On a 14mm stud, that 1mm difference is not much room to play with so I doubt we can find an ET lug nut that fits; having less than .5mm of material backing those extended threads would probably be pointless anyway.

That makes replacing the lug studs on all four corners the only option, which will definitely be a PIA to DIY. Please let us know if you find a suitable replacement for the OEM studs.

Ooof! Thanks for the heads up. I think that’s the deal breaker for me. I already have a Taco that I performed extensive “surgery” on. Don’t want to start on that slippery slope again.

Does this mean that ordering this is wrong?

It means that compared to wheels that are designed for extended thread lugnuts, you will have to do some extra work for maximum strength and safety; you will need to replace all your wheel studs with slightly longer ones. The process is not that complicated but definitely tedious since you will have to remove all 4 calipers, all 4 rotors, press out 24 studs, and press in 24 new ones.
