Tyre technology has advanced enormously since the golden era of British motorcycling, and choosing the right tyres for a classic motorcycle involves balancing several considerations: period-appropriate appearance, modern safety performance, and compatibility with older wheel rims and suspension geometries. At South Wales Classic Motorbikes, tyre selection is something we advise on regularly, and the range of options available to classic owners has never been better.
The Case for Modern Tyres
The compound and construction technology used in modern motorcycle tyres is vastly superior to anything available when most classic machines were built. Modern tyres offer dramatically improved wet weather grip, greater resistance to punctures, and much longer service life than period-correct alternatives. For a classic that is ridden regularly rather than shown, the safety and performance advantages of a modern tyre are difficult to argue against.
Period-Correct Options
For concours competition or historically accurate presentation, period-correct tyre specifications may be required or preferred. Manufacturers including Avon, Metzeler, Dunlop, and Coker produce tyres with period-appropriate tread patterns and crossply construction that are dimensionally correct for classic wheels. These tyres look the part while incorporating modern compound technology that improves their performance over genuine vintage tyres.
Sizing and Rim Compatibility
Classic motorcycles were built to use tyre sizes that are no longer the industry standard — many use imperial sizing (such as 3.25-19 or 4.00-18) rather than the metric sizing that is now universal. Most classic tyre suppliers offer these sizes, but availability of specific sizes in specific tread patterns can be limited. Checking availability before committing to a rim size when rebuilding a wheel is advisable.
Tube or Tubeless?
Classic motorcycle wheels were designed for tube-type tyres, and this should be maintained unless the wheel has been specifically rebuilt or converted for tubeless use. Running a tubeless tyre on a tube-type rim without an inner tube is dangerous and should never be attempted. Most classic tyre fitments therefore require an inner tube, which adds a small additional cost to each tyre fitting.
