....got it through my thick head that slow steering might, just might, be related to low front tyre pressure. As it's such nice weather, I took the LC4 out for a spin earlier - very funny feeling from the front: slow steering, and a reluctance to turn right at all. *ding* went the lightbulb above my head - "I've been here before" I though. Sure enough, took it to the next petrol station, and checked the tyre pressures: 29psi in the rear, and *cough* 8psi in the front. That'll be that then. Sure enough, filled both up to 32psi and off I went, happy as larry on a properly handling LC4[1] [1] for LC4 values of "proper handling" of course.
