285/75/16's on a frontera

Unread post by loppa » February 27th, 2009, 6:23 pm

Hey guys going to buy new tyres soon and want 33's, Im looking at buying the silverstone mt 117 sport in the 285 75 16. How do you think they would go (power wise) on my fronty I have a little 2.2l petrol?

just change the gears in the diff and the rotors to slotted rotors, you'll be fine (braking is a good thing to have also)

which year fronty do you have (might be able to use the jackaroo centres)

modified 12 bolt diff, you can use the jackaroo diff ratios

- quote from the jackaroo section of australia4wd.com

might pay to make a post in the main section, asking how to calculate diff ratios needed for tyre size increases
In the 98 and later models, the 3.5V6 auto is a 4.1:1 diff. The V6 manual and the 3.0 diesel are 4.3:1 diff.

The manual also lists a 4.555:1 and 4.777:1 diffs that were in the older 3.1 diesels and 3.2 petrols.
Gear ratio (to 1)
4.100(6VE1)
4.300(4JX1, 6VE1)
4.555(4JG2–TC, 6VD1)
4.777(4JG2)

Your low down torque would be less, just means more clutch work on the uphill/rock ledges and soft sand, but should be right.
I'm assuming that you have had a suspension and body lifts done ?

my son has 33's on his 98 fronty. You can see it going up a hill we call widowmaker before guzzler, a couple of issues back on the mags DVD. They called it a MU, but it is a 2.2 fronty like yours. It still goes fine on the highway, but the gearing is too high for 4wding in the steep country.

Well guys i ordered my tyres today I stayed away from the silverstone mtt 117 sports in 285/75/16's and went the maxxis bighorns in a 255/85/16 to try and keep the width down but still have a 33 on it.

255/85 should also fit inside your wheel wells on the stock rims

At least at that width its far less strain on the steering components. Wish I could trade my 33 x 12.5 Bighorns for a set of 33x 10.5 for that same reason.

Cheers
