will bigger wheels change my speedo

[Boonz]

ask the copper lol he rekons its 7% but hey i could of seen wrong....... say if your rims were 18's and your tyres were 18/235/35 then your speedo would be ok because you ahvent changed the original outside diameter of the tyre

Im not sure it they're 35s or 40s. . . . one of the two.

They're 235s but I need 245s, the edges r rolled in too much.
Does the copper even answer ne I ne more?
Seemed people just bagged him. . . .

my mate with a vr has 18's and 40 profile tyres and his speedo is actually out by 4 km's when he was on the dyno so id say that 35 profile will make it correct

Depends what width tyre he used.

2 ears 1 mouth

i'm in the market for a set of 18's to put on my vx, and a mate of mine (who knows ****all about cars but is a real know it all) says to me

"if ur whells become bigger wont that make ur speedo in-accurate"

will bigger wheels and tyers make my speedo read slower that the car is accually going?

Does my speedo need to be recalibrated?

Help soon (cause to treed on my back tyers is really bad and i need new tyres soon)

seems your mate knows more than you oh wise 1.. An old friend of mine who has passed once said to me " do you know why you have 2 ears and 1 mouth?" i said "why" he said " because you should talk less and listen more"

I reckon he's figured it out 10 years later.
