After having a new set of tyres fitted on Saturday My GQ has got the worst steering shudder at any speed over 40 K's. It probably doesn't help that they are 34" Simex jungle trekkers. My mate has the same tyres on his GQ and doesn't have a problem. The car is going back on sat to get an on car balance to hopefully cure the problem. If any body has any other ideas it would be appreciated.
I fitted a new rancho steering damper today but it made no differance.
If anyone is thinking of getting the jungle trekkers I can vouch that they transformed the GQ's performance on Sunday 100% compared to my 33" BFG muddies.
Mark.

JT2's are good until you come to sideways grip, like a off camber corner on a long downhill.
They are like boggers, Claws, and Xterrains, suffer from no sideways grip.. but good for 360's!
Enjoy em!

PS... it sucks, but to be legal, and have insurance... you need an engineers with 34's and they wont engineer JT2's...

Hi Mark,
Realise that you running some pretty extreme rubber,
well compared to most H/T or A/T patterns. However, this sounds like a balance issue.
Check out recent post #5798 that discussed this same topic (GU/ GQ wheel balance).

Hi
Have you checked the wheel nuts are tight?
Did you use new rims with these tyres?
They could have been drilled off centre or they might be hitting the calliper.
Jack up each front wheel and spin them looking for these things or anything else that might look unusual.

This is a common fault with Nissan's. Nissan blames the tyres; the tyre man blames the stabiliser/wheel bearings/birfield joints/ball joints etc.etc. All I know is that the tyre/wheel balance has to be absolutely spot on, preferrably on the vehicle.
I am interested in your impressions of the Jungles' viz;
a] Are they 15's or 16's?
b]What pressures did you try out?
c]How is ride quality and on-road noise?
d] What width wheel did you go for?

HI Steve,
My first immpressions on the JT2's are superb, it feels like I have fitted a locker they give you so much grip, compared to my 33" BFG muddies which aren't very good in the slippy stuff.
They are 34x10.5x15, 35psi on the road and 18psi on Sunday in very deep sloppy mud. The on road noise sounds like you have an aeroplane sitting on the roof but I can live with that, and the rims are 15x8 powder coated gun metal
grey. You can feel every tread when you come to slow down.
I would recomend them as they are alot cheaper than the centipedes but not as your daily tyre as you may get an ear infection with the noise.
Thanks for the responces
mark.

Thanks for that Mark. I think I'll give them a try once the BFG's have worn out. Cheers.

Mark,
I have experienced this problem also.. On my 90 GQ (2"
suspension lift/0" body lift) 3 years ago I upgraded to 33" BFG Muds. for the 1st year they were great, But after a 3000 k trip to
Adelaide and back I discovered sawtoothing on my steering tyres and decided to rotate front to rear. This brought on the problem of a wobble in my steering wheels.
I then spent some time rebalancing them to discover that the wobble can be gotten rid of if the tyres are perfectly balanced.
Nowadays I balance my tyres every year as I rotate them.. ( I'm only a low kms user approx 10000kms/yr)
Also my Father-inlaw 99 GU (3"
suspension lift/ 0" body lift) had a similar problem when he had new 31" goodyears put on last year. And my Dad has had simliar experience with 31" Toyos on his 91 GQ (0"
suspension lift/ 0" body lift) but hasn't had any problems since he went to 31" Coopers.
I my opinion this is related to caster angle but haven't had time to adjust it and see..
Cheers
