New WHEEL - Probably v.easy answers.

[highguyuk]

Hey,

Need to get a new spare, wheel and tyre. Have 14" on and discovered spare is only 13"

Was going to go to the scrappy and get a cheap wheel and get new tyre fitted onto it. Not sure about swopping tyres and stuff for best wear (?)

Anyway, my tyres are 185/65/14. So in looking for a replacement WHEEL :

a) It has to be 14" (duh!)
b) Does it have to be specific to fit a 185?
c) Does it have to be a 65? Ive heard it could be 5 either way ...
d) Does it have to be any specific wheel, or will any fit. It will only be a spare, ive got alloys for my car.

Thanks again for any help!

Keep the 13" wheel if it's just a spare.
Otherwise go to scrappy and get another 14" wheel with a tyre from the same model car.

But surely the spare should match the set?

Does this have an effect on the MOT perhaps?

[Mookfish]

The spare dosn't have to match the rest of the wheels, just have the same rolling radius, (i.e. if you wrap a tape measure around the spare then one of the normal wheels you should get about the same measurement.)

This is the principal behind spacesaver spare wheels. Also the spare is not part of the MOT, although there are many testers who would dispute this. (mostly ones working in tyre centres.)

Also it is normal to have four alloys and a steel spare.

Just discovered a flat tyre and got it all replaced with my spare tyre. However, the spare is only a 13" and mine are 15" and I had alloys etc so it needs to be done pronto. (http://forums.moneysavingexpert.com/showthread.html?t=165407)
On another note...
Ideally all the tyres on your car should match exactly (i.e. type, brand etc..) so that the tyres should react in the same way, preventing a mismatch in performance when in use.

It has also been suggested that when you change/replace a tyre, it's better to change them in pairs or have 2 wheels which are in exactly the same/similar condition put on the same axle. Obviously if you have had one wheel replaced recently and its only a few months old (for example) you won't need to replace 2wheels (if replacing a new wheel) if all the other tyres on your vehicle is in excellent condition (unless the tyres are worn down, for example).

Sorry to hijack your thread but I hope this is of use to you and others reading this. :)

The spare can be a smaller wheel. Most modern cars with large alloy wheels have a steel or spacsaver spare to keep cost down and so as not to use much boot space.

That said, the handling of the car will be altered when wheels of a different dimension are fitted, and this is a TEMPORARY solution to get you to a garage.

The tyre size - 185/65/14 - you would be safer keeping the same if you're going to the trouble of finding a rim the same. That way you can leave the spare on and not bother changing it back if you wish.

185 is the width in mm
65 is the height of the sidewall as a percentage of the width - ie 65% of 185 = 120.55mm.

Both will affect rolling radius. Easier and safer just to keep it all the same.

No hijacking here at all, all helpful.

My tyres have shrunk in size from 185/85/15 to 185/65/14. When I first looked, it was dark ... honest!!! Always thought I had 15" as well, never mind.

For the time being, I had a new tyre for my original flat puncture, and a puncture repair done on another tyre that it was discovered had a nail in it (repair done professionally). The 13" spare has gone back underneath, but will look out for a 14" at a scrappy in the near future to replace it.

Thanks for the help everyone, I think it would be worthwhile to have a tyre sticky on this thread as there are often lots of questions. What you all reckon?

A point also you may want to look into is the offset of the wheel i.e. how the wheel sits against the hub. Different makes of cars have different offsets so make sure any replacement wheels you get have the same offset or it will seriously affect the handling of your car.

[tomstickland]

If it's just an "emergency" spare then I wouldn't worry about the offset etc - treat it like a run flat.

The holes will have to be right though - pitch circle and number of holes. This is why it's best to go to a scrappy and get a spare from the same model or manufacturer.

A tip for those with space saver wheels. Should you get a front wheel puncture - do not put the space save on the front. Take one of the rear wheels off and use the spacesaver here - replacing the punctured wheel with the good wheel. Then dont drive above 50mph.
