I put new tires on my MGB today. After searching the archives I concluded that I should buy 175-70 R14's (Michelin) to replace the 185-70 R14's which I bought nine years ago. The 175's look much better on the car and, based on a short test drive, seem to make the car feel a bit more stable at speed. Hope others will find this helpful. Peter Schauss 1980 MGB
