Tyre size compatibility - frostbite
My car is currently fitted with 205/50 16 but one of them is barely legal. I have been offered a 215/55 16. Is this slight difference in width & profile significant (and legal) for one corner?

No, you would have to buy a pair and bput them on one axle but I would not do it, buy the right tyre. Regards Peter

It's not a slight difference, it's actually about 30mm or 5% of the total diameter of the wheel and tyre combination and would in no way be safe.

Even putting a pair on an axle could have some implications for handling if the other tyres didn't match, and your speedo would be inaccurate if it isn't already.

Quick calculation - the circumference of the new tyre is 5% greater than the old one, which is a lot. I doubt your insurance company would be very impressed if you crashed with two different tyre sizes on the same axle.

I've got some good 205/50 R16s if you're interested. (Location - near Ipswich). They're on very tatty alloys, and they'll be cheap.

Thanks for that chaps - knew I could depend on the backroomers for good advice (i.e. DON'T!).

Richard, could well be interested there, would you like to email me frostbite@lineone.net.
