Hi just bought a 2000 Gu ute 4.2 and had it for a bit and got new tires on it the other day and now a massive wobble happens as soon as I get over 75k's but before I got he tires I had a little tiny wobble at 80 but nothing u would really notice any ideas of y this could be happening. I Am new to this site and new to patrols as this is my first one any help would b appreciated to fix it for a reasonable price as I'm only a apprentice haha
Cheers

If it wobbles after new tyres, the tyres are not balanced properly.
I have had it happen to me, take them back and give the tyre place a chance to balance them again, obviously at no cost to yourself.

btw: what size tyre and tread?

"New" tyres or "new" for u tyres (2nd handies) ???

x2 both above comments. My new maxxis 751's wobbled a lot, i took them back and the tyre mob apologiesed and re weighted them. however some tyres you just cant balance (from experience) e.g if you have 37" super swampers missing lugs and chipped to christ it's gonna be a lost cause ;-).

The tires are brand new 265 75 16's Mickey Thompson fc II didn't go for any thing special really that's y I found it strange that iv hot a wobble considering they are the same size as the old ones!
Cheers for the replys guys

there are a few reasons it could be , it could just be coincidence that it is just when you changed the tires it has happed.
Have you checked your bushes for tears?
what is your bump stop height?
what is your caster reading?
what are you using for caster correction.
how is your panhard bush mount in the chassis
how tight are your wheel bearings
is a rim buckled that you didnt notice ?
there are a quick few things to look at, there are still a few more but at least this will give you a point to start.
We have had customers that have had these type of problems but it has been from the suspension height change from a 4wd trip recently and this has altered the caster without the customer knowing.
Nissans are tempremental but not had to fix if you know where to look.

Great tips ^^^

Wouldnt a rim buckle be noticed on a wheel balance machine ???
Generally IF i get a wheel balanced and theres too many wieghts in one area,
The rim has some damage of sorts
I usually check this stuff,cause the boofhead doin the balancing will just keep wacking wieghts on
