Tyre and wheels sizes

[grabenson]

Hi all,

have just a got a audi a4, my first audi and loveing it so far, the car has some very nice bbs alloys on with 225/40/18 on lok very smart, but the spare wheel is an origanl alloy with a 205/55/16, what i need to no is do they match ok if i have a flat tyre and put the spare on !

It will fit but there will be a diameter difference of 4.24 which equates to a rim + tyre difference of 28mm.

Thanks for that chris will that cause me a problem if i use it than !

maybe it will be better if i look round for an other alloy to gom with the other four, why do people buy only 4 alloys,

PS or what wheel or tyre would i be able to use to make it safe !

no it wont matter if used for a spare while getting main wheel fixed. i have 19" rims with et 35, but spare is a 16" with et42. often drive with spare on as wont let a garage jack my car up, as have a votex bodykit and they nearly ripped it off. so when have puncture etc will remove tyre myself before going garage, but i have no issues when spare on.

i posted a part about tyrs sizes on here, i bought a new set of wheels and just after i put them on i had a humming noise, a so called mate insisted it was bad tyres on my car, what an *** he was, it wasnt at all, it was what i suspected all along, a faulty wheel bearing, waste of money on new tyres
