The potential owner is in London and the car is in Bradford. Just waiting for her to get back to me and if she is interested I will be hoping someone local can give it a once over. It wont be ready until the end of the week.
I have no free time for 5 weeks.
Anybody.
You will be fine, the zed is a great car for distance driving. I regularily do long drives and I am and old duffer with a bad back. Never had a problem.
Your car works out the balance assuming that all tyres have the same characteristics and so IMO anything that isnt matched will have an effect on how your traction control responds.
If you have the same tyres at each end that helps but unequal wear will always make a difference.
I know its expensive but I always change all tyres at the same time.
