I have heard of swapping front to rear to equalise wear but never side to side. I have been told that once a radial tyre has been used it shouldn't be refitted to rotate in the opposite direction.

What you say Iliacus makes sense and refitting road wheels to opposite sides of the same axle should not be done if you have uni-directional tyres fitted.

They will have an arrow on them with the word 'direction' or 'rotation' on them next to the arrow. The arrow must point in the direction the wheel will rotate when rolling forwards. They can only be swapped to the other side if removed from rims, rotated and then refitted. The other tyres may be asymmetric and will have 'outside' marked on them which must face the, errr, outside of the vehicle. They can be swapped to the other side with no problems. Any tyres with no markings are symmetric and can also be swapped from side to side with no problems. Just make sure you don't have a uni directional tyre as your spare - you've only got a 50/50 chance of being able to use it legally! Past: FL2 TD4 HSE Auto

Steve D - what's your evidence for using a unidirectional tyre the wrong way round being illegal? I've never seen any legislation to that effect (and in fact it's more or less standard practice in the army, owing to the incompetence of the fitters...).

Well, as an MOT tester I know a car will definitely not pass an MOT test with a uni directional or asymmetrical tyre fitted not in accordance with the manufacturers markings on the sidewall and I'm assuming that would make it illegal. Can't quote the exact law that would be broken, if any. I do know that cars can pass the mot test but still be illegal the minute they go on the road though so perhaps the opposite may also apply eg fail the test but be legal to drive on the road. If so, I may be wrong with the 'illegal' bit of my previous statement. Anyone versed on the law on here? Past: FL2 TD4 HSE Auto

That's very interesting. I did look into the legislation a while ago regarding different size wheels/tyres on the same axle, and the only legislation I could find was the old one about not mixing crossply/radial on the same axle. I entirely agree it would be bad practice, but I haven't seen any legal thing. A lot of MoT items seem to be down to MoT regs, not to anything enshrined in law. Would you pass a car with a 17" and a 19" on the same axle (perfectly legal, and a possibility with the standard FR2 spare wheel)? |

I have swapped wheels front to back regularly on my last few vehicles ( all 4 x 4's ) when either fronts or rears we're wearing a little bit faster so the wear is evened out on the tyres

Definitely not. Must be the same type, size, width, aspect ratio etc across the same axle. Obviously you can use any size as a spare wheel (spacesaver) legally on the road but I think you are restricted to 50mph which is why most spare wheels have a ’50mph' sticker on them.

Just had a look at the MoT rgs on http://www.motinfo.gov.uk/htdocs/m4s04000105.htm

Just saw your last post Steve - yes I agree that it makes perfect sense, but again I can't see any strictly legal basis for that. FR2s are sold with a 17" spare when different size wheels are fitted, or sometimes with the same size wheel but a different size tyre. It must be legal to drive with these, although obviously far from ideal. |

That's true about the arrow thing - but like I said earlier, to be valid it must also say 'direction' or 'rotation' next to the arrow. The specific reason for that rule is because there is a brand of tyre out there that is made by a company called 'Arrow' and an arrow is their trademark that they have on their sidewalls!

Significant MOT failure points would be covered under 'Vehicle in Dangerous Condition' if there isn't a specific offence. Good old 'Construction & Use' again. |

I questioned the wheels being swapped on the same axle on my service's by LR in the past.
