Since I had my car Geo set to A110 Life fast road and track settings I get Tyre skipping when maneuvering and slow speeds (parking etc) on near to full lock on the steering.
Has anyone else experienced this is it normal?
I'm fairly sure it never did it before the Geo.

Normal. Look up 'Ackermann angle'

Crabbing? I've noticed it happening a little both before and after getting the Life110 geo iirc. Usually on cold mornings.

Not sure if tyre pressures are a factor, but mine were low before I got the geo done and Matt at Spires set them all optimally.

Either way, it's nowhere near as bad as I've experienced in my last car (Lexus RCF) which had wider and lower profile tyres.

Its this. Happens most when the road is slippy or cold.

It's very common on the Hyundai i20N. A bit disconcerting at first on a brand new car but a combination of the suspension settings, limited slip dif and special P Zero tyres cause's it. Apparently it's a lot better when switching to Michelin PS5 tyres as the Pirellis are particularly prone to it when cold although not quite as bad when warmed up. It's the price for optimum steering feel and ultimate handling.

Would I be right in saying the more aggressive Geo would make it more prevalent as I don't think I noticed it before.

Its nothing to do with the LSD. This always gets trotted out in RS Megane circles too. It's the steering geometry, road surface and tyres.

My Clio 182 used to do it (open diff). It's common on plenty of RWD cars too.
