Jaguar XJ220 owners: you can now buy replacement tyres for your supercar

9 September, 2016

“Produced from 1992–1994, the Jaguar XJ220 has gone a long time without new rubber — but that is set to change thanks to Bridgestone.”

When you look at the Jaguar XJ220 it’s easily identified as a ’90s supercar. Its wheels are too small, it lacks modern aero, and it has an interior almost pinched from a 1991 Mitsubishi GTO. The ’90s were a long time ago, and so was the last time Jaguar XJ220 owners have been able to buy replacement tyres. A scary thought considering the XJ220 is capable of reaching 349.4kph — and it held the Guinness Book of Records fastest speed ever attained by a standard production car from 1994 to 1999. 

Just recently though, Bridgestone announced that they have teamed up with Don Law of Don Law Racing to develop a new OEM-spec tyre for the XJ220. Something as simple as a tyre has no doubt hurt resale value of the iconic ’90s machine, so it’ll be interesting to watch the prices skyrocket once people start getting them out of their storage holds. The new Bridgestone tyre is said to greatly outperform the original due to the advancements in tyre technology, which will be exciting to see, and they’ll be ready for the car’s 25th anniversary in 2017. If you’re curious about just how big the tyres are, try 255/55R17 tyres up front and 345/35R18 tyres down the back — just bonkers. That’s 300mm short of one metre of rubber touching the ground, just on the back! 

The XJ220 was an interesting beast. Originally it was meant to be a V12 all-wheel drive, and after taking 1500 £50,000 deposits Jaguar changed their mind, dropped two driving wheels, halved the amount of pistons and added two turbochargers — weird right? This came at a time when only Japan was producing such vehicles, as European supercars were meant to be V8, V10, or V12, and, more importantly, naturally aspirated. 

Jeremy Clarkson once described the turbocharger lag of the XJ220 to be terrible, and demonstrated by putting his foot down and counting until the boost came in. When it did come in it was quick, and produced 400kW (550hp) and 644Nm (475lb-ft) of torque. The XJ220 would accelerate to 100kph in only 3.6 seconds, which even by today’s standards is seriously moving. The 3.5-litre V6 engine found in the production XJ220 was dry-sumped, had Zytek multi-point injection with dual injectors and Zytek electronic engine management — all way ahead of its time. The engine block was produced from aluminium, as were the heads. An interesting note is that the XJ220 would receive 8.8L/100kms, which matches most common commuter cars of today. Not surprising though when you think how bad the turbocharger lag was — it was probably never on boost! 

Coaching from the bench: Casting plastic knobs and rubber parts

16 July, 2026

Casting rubber items is simple if you have a good original to work with. The item doesn’t have to be perfect. You can use plasticine to smooth out cracks, and you can even make whole prototypes out of low-fire modelling clay available from craft stores if you need to. Prototypes can also be made of wood or metal.
You will need mould dams to contain the liquid urethane moulding solution until it cures. You can build boxes out of strips of wood, but I have found that small plastic boxes and bowls such as those you would use for leftovers in your fridge work well if you spray them with a mould release agent.
Temperature is important to the chemical processes involved, so work in an area that can be maintained at around 20 degrees. You will also need adequate ventilation because the fumes can be dangerous to breathe. And you will want to wear latex gloves to protect your hands.

Fraser Cars – low flying into the fourth decade

10 July, 2026

With almost three and a half decades under its belt, Fraser Cars is one of New Zealand’s longest-surviving car manufacturers. The company first opened its doors for business in 1988, during the boom time for kit manufacturers. During the ’80s, around 40 different companies were building kits and turnkey cars for this niche market. Of those, only Fraser and Almac Cars (established 1981) are still in business today.
Most of the new kit car companies were killed off in the cradle by the threat of new legislation that never eventuated and definitively by the sudden availability of high-performance Japanese cars when the floodgates to second-hand imports were opened. The now long-retired founder of the company, Neil Fraser, first came across Lotus Seven replicas while racing Lotus Cortinas in the early ’80s. He regularly found himself racing against a little Caterham, a Lotus Seven–styled car built in England. He was very impressed by its simplicity and handling. In 1986 Fraser built his own Lotus Seven–type car, using the knowledge he had gained from several close looks at the Caterham.
