Hi Chaps, Not been on for a while but change of vehicle prompts a question.

I believe it's because it's on a steel rim. You could always look on the well known auction site for a full size spare on an alloy rim to get round the speed limitation. |

I'm sure I read somewhere, probably on here, that the speed restriction was due to the taper on the wheel nuts not matching that on the steel wheel. You'd think if that was the case then JLR would have specified a steel wheel with the same taper. |

I know that for mot purposes, the tyres across an axle must be the same size and aspect ratio. I believe the law makes an exception for different size tyres for temporary emergency use as long as the speed is limited, hence the 50mph/80kph (not 30mph/50kph as has been said earlier) sticker on the wheel. Nothing to do with using a combination of steel and alloy rims (well, at least as far as the mot is concerned). My FL HSE has 18" alloys as standard but the spare is a 17" steel one although both have the same external circumference due to the 17" using a 'taller' tyre. If you had an 18" steel wheel with the same size and aspect ratio tyre there would be no speed restrictions. As others have already said, get a same size alloy spare but if you are worried about a reduced towing speed, aren't caravans/trailers limited to 50mph anyway? |

Thanks for the replies. I have been and checked the wheel, and you are correct its 80 kmh/50 mph not 50/30 as i first thought. So that's a result. You can tow at 60 mph on motorways, but with a spare on, 50 won't be a problem. Me thinks its got to be better than a kit repaired tire. Not had any experience with modern systems, hopefully will never need to. Will also check the wheel nut taper difference - thanks for that.
