Worrying weave!

Bikermutt:
Hey all,
This is my first post outside of the newbie section. I have just put some new wheels on my Discovery 200TDi with Bronco Grizzly Claws & the steering has now developed a mindn of its own over 45 MPH, just seems to weave all over the road! To keep you informed, the previous tyres were road orientated Michelins  the suspension has a 2" lift. Anybody experienced similar symptoms?

Disco Matt:
I would guess that the lift has upset the steering castor angle - I know people say that you can do a 2" lift without needing castor corrected swivel housings (or radius arms, but I'd rather change the swivels as I've heard of a few failures of aftermarket arms) but from my brief experience of HD springs it is noticeable. On standard springs it feels much more settled.

The tyres may well make it wander a bit, my Insa Turbo Dakars are vague and understeery in corners compared to the BFG A/Ts I had before. You do get used to it and it improved a lot once I got rid of the HD springs in favour of standard ones.

Range Rover Blues:
If you swap the swivels then get the Tomcat Motorsport ones that are castor corrected from new.  I've heard about QT arms failing but mine have been fine and TBH I think that fitting catsor corrected arms solves more problems than just the castro angle.

Plan C, the chepaest option is ofset polybushes, though they do restrict a bit of body roll.  Good on road, bad off it.

Bikermutt:
Thanks for the advice, I have since put my old tyres & wheels back on & it is fine again so defo a tyre issue! Am suprised at how much difference the tyre change has made, all I can think is that I have duff tyres!

topless matt:
Well, i can tell you now, it is def the grizzley claws....absolutly shocking tyre on the road.
Mine had a mind of their own and i put up with it until 3 delaminated on the same 50 mile journey......never buy bronco tyres again!
