alloy effects

[sickrabbit]

peeps i,m a new driver ( proud mk 2 first car ) wanting to upgrade my 13,s to 15,s which i won on ebay. they are nova specific so i,ll have no sizing problems - but - mates have told me to change up a sizing in wheels will result in false speed readings..is this true ??
i really wanna do this cos me motors in great nick and these Fox rims i,ve won will set the scene.

cheers - happy new years.

the speedos are miles out any way mate just wack em on

they should affect the speedo, if you stick to 195/45/15 or 195/50/15

my 15's with 195/45's have a smaller rolling radius than the 13's that came off it :S

what size tyres are on standard nova steelies?

[sickrabbit]

at the mo the size : 145 / 45 ...the car has no modifications to its suspension..( worried the 15s may rub... :o

[smithy87]

With standard suspension, especially on a MK2, you should have no trouble with rubbing/scrubbing mate 8)

[sickrabbit]

there was a slight rubbing , that has now been sorted by the angle grinder ....
i cannot get over the affect these rims n tyres have had on my pride n joy...slower on take off , but quicker on top end..also the steerings almost like power steering , and the car feels like its on rails - stable..
many thanks for the advice :lol:

forget every thing about the speedo reading when putting new wheels on as long as the off sets ok there should be no problems at all, then lower it lol
