but then dont forget its illegal to have thinner tyres on the back of the car,

just change them all , youll be ok temp.as for putting it on back what if you had a car with wider wheels on back (ie porsche 911) if you had a puncture on front you have to use space saver , you would not get back wheel on front, too wide.

you really want the fronts and the rears the same, for a handling and safety point of view. I imagin if you were to emergancy stop at the moment you could easily spin.

Dont worry about the diff, but if you are, stick the 15 on the back where there isn't one. This would also be safer from a braking point of view.

Personally I'd just stick all the 15's back on.

yeah ur right, sorry, i probably didnt read the post correctly :rolleyes:

if i do that though i may as well put 15's on all round :(

id put 15's on front n put 18's on rear for time being

its not a puncture its 2 suspicious/malicious holes in my 215/35/18 brand new pirelli tyre wall :( my mate at tyre place says its irrepairable and i cant afford a tyre at min kus of xmas ect

i don't really know a lot about it to be honest Kerry but I have heard it's not good to have to sdifferent size rims on the front and if you are going to do it then do it on the rear, how much is a puncture repair anyhow about £4, get yerself to the garage and get it fixed and there will be no worries for you, Regards Paul...

i was thinkin that actually but then the tyre on the 15 is actually better than my rear 18's if u get me

would it not be best to swap the 15 with one of the rears ?

driving with 3 18's and a 15 alloy??

18 and 15 on front but same rolling radius, drives fine but someone mentioned my diff :boggle:

oh and i know its illegal my alloy is in the boot i just changed it ;)
