Hmmm TVR's come supplied with a space saver .... If you run with a space saver spare on your vehicle ... should you make that call to your insurance company everytime you need to use it ?
If you are driving the car with the space saver on and you have an accident, is your insurance null?
I dont think insurance companies have clauses for "running whilst using a space saver"


I rest my case

But surely the space saver is part of the original specification of the car, so unless you are going over 50mph thats fine, if you are running something that does not conform to the original spec then thats when the insurance companies must have a case.

Space savers are part of the Manufacturer's original equipment so no problem. No need to rest your case.

As an aside, I saw a big merc barrolling down the M1 with one of these on, still doing 90 mph a few inches back from the car in front. I imagine it had some sort of ABS/stabiliser thingy because he didn't *quite* spin when the traffic slowed down. Did look awfully entertaining though. Presumably he was late and in a bad mood from having a puncture?

There seem to be four issues here at the moment:-
1 The law regarding tyres
2 Manufacturer's original specification
3 Insurance companies
4 Spare wheels

1 See the useful Government website mentioned by jvaughan. Offenses all relate to the condition of the tyre, apart from unsuitability. Tyres have to be suitable for the use of the vehicle and be compatible with the tyres fitted to the other wheels. This leads to;-

2 Speaking to TVR and many tyre manufactures: stay close to the original rolling diameter, tyre width, aspect ratio and weight rating and do not decrease the speed rating. Imanaged to speak to John Ravenscroft( the chief developement engineer ) about this whilst having my car serviced at the factory. My 350i had 205/55R15s on the front and 225/50R15s on the rear( a 3% reduction in rolling radius ) and i was considering 205/50s at the front. He thought that 205/50s would upset the suspension angles.
The tyre manufactures are also helpful; many even publish tables, for example see the TVR website. Tyre technology has advanced considerably in the 19 years since the 350 was introduced and the original construction Goodyear NCT ( as specified on page 59 of the handbook ) are obsolete. Thus 350 owners will have to run with 3% smaller diameter wheels if they are to enjoy the benefits of state of the art tyre technology. ( Where are these mythical 350s running on Bayford's leaded fuel, Unipart spark plugs, Armstrong dampers, and Unipart oil filters? )

3 Once a correctly completed proposal form has been accepted insurance should be valid.

4 The spare wheel was originally full size, then a space saver was introduced as a priced option; then the space saver was a no-cost option, then the full sized spare was a priced option. It is not pleasant driving the 350 at any speeed with the space saver on.


Has phil350i bought any tyres and has anyone tried A048Rs yet?
