"Friends of yours were having tyre selection issues or doubts with their MGF and I was going to point you at a superb website. You might already be aware of it but if your friends join the group and go into
MG BBS > BBS archive > MGF technical > Tyre selection > Tyre selection
they will find a thread started by me and one of the respondents refers to a web site on which there is a tyre satisfaction survey. It worked for me, we binned the Kumhos and fitted Toyo, transformed the car.
I have found the site fascinating and extremely helpful with both the F and the Midget.
Best regards,
Adam"
