33's or 35's??????

[Richo460]

I have 33" bighorn muddies on my gq but am wondering about a set of 35" muddies on a set of mickey thomson classic lock rims. reckon that would look sweet but i want to consider a few more factors and i need to hear from people who have had both and what they prefer.
Will 35's improve its off road performace by much?
Will 35's decrease the on road performace much?
Fuel economy i guess will be a little worse but how much is to be expected with a TD42?
Will the extra weight of 35's be a factor?
Whats the deal with reduction gears? As far as i am concearned i just want it to be revving nicely at 60, 80 and 100k's.
Any input and experiences would be appreciated.
Cheers

I really really want 35's currently got 33 mtz. But really will need reduction gears in the really steep stuff I can stall in low 1 now let alone with 35's
Edit: NA td42

hmmm. How much does it cost for a set of reduction gears? Are the transfer cases in GQ's chain or gear driven? Surely it can't be too hard to install a set yourself. just take a while. but with wheels and gears it sound like an expensive time consuming excercise.

Check out big rigs members ride thread "Tank Big Grey and Ugly" or message him, hes done em and absolutely loves em

Also consider just changing the diff ratio. Downside is it affects all your gears (not just the transfer case), upside is its relatively easy to install yourself

35's are great for offroad. 33's are a good all round size. Your fuel economy wont vary much but your speedo will be out and in being so will actually read less on your odometer than you have actually travelled (hence thought less mileage) as a 35" tyre doesnt have to as many revolutions as say a 31" tyre over the same distance and since your speedo etc is calibrated for 31" tyres it will be out. An example of this, me and a mate travelled to gympie myself on 33's and my mate on 35's when we got to gympie (150km trip) my trip meter said i had travelled 20km further than him (both zeroed at start of journey). As 35's wont have to to do as many revolutions your engine wont have to rev as hard, 4.6 diff ratios (2.8TD) will bring your speedo and revs back it to alignment with standard. Then if you do a lot of offroading reduction gears are awesome and by memory i think retail for about 1250-1350 and a GQ transfer case is chain driven (this job can easily be tackled in your shed on a weekend). Hope this helps.

I am running 33's at the mo and have just got my hands on a set of nearly new 35" beadlocked Simex's. I am using them for the first time in a couple of weeks (GQ). I will let you know results. May have to up the boost and play around with the air / fuel ratios but everyone local reckons will be pretty sweet.

just wondering how you went with the 35's mate as i am looking for a set myself

just wondering how the TB42 will handle them as i cant afford reduction gears atm and will be hitting some pretty steep stuff
