Tyres


 * Standard fit is 135/80/13, or 145/80/13. This size is getting a little uncommon and the best source may be an online tyre provider such as Blackcircles.com who can either supply casings by mail order or arrange a local fitting.
 * Due to the lack of central holes in most R4 wheels, some tyre centres may not be able to balance your wheels, and may have to fit the tyre manually. Check in advance.
 * The wheels are suitable for tubeless tyres in spite of what you may be told.
 * Current recommendations are that tyres over 5 years old should not be used. The Michelin website amongst others, gives a key to the DOT code on your tyrewall which will tell you how old they are. If you are putting a car on the road that has been sat for many years the tyres may look fine, but the compound may be weathered, hardened, may have flat spots and may delaminate under high speed cruising (whatever that is!).
 * The MOT only looks at tread depth and pattern, and serious visible defects such as cuts, but not tyre age. You may get an advisory for surface crazing on tyre walls, but tyres over the critical age will not be flagged. Don’t assume that because your new buy has an MOT that the tyres are fit for purpose!
