Hey . I have larger wheels than standard on my Mk3 Polo 15"

Will the Speedo be out as i dont believe that it could of gotten to 115Mph on the way home form Edition .. I was pushing it on the way home down the M1 yes but its only a tuned 1.0l

How much will the speedo be out iff anything for future reference ??

what tyres you running? if you have 165/50s then it will be hardly out at all

they're usually about 5mph out anyway, thats on the standard 13s.

I'm not too sure what it would be on 15s though

what tyres you running? if you have 165/50s then it will be hardly out at all

195/45's

It'll be out. I was running 195/45's onm 14's and that was out.. Do a search in google for miata tyre size calculator.

That says that my speed will be reading 12% faster on the clock .. crazy ..

92Mph .. Hmmmm

meh... when I'm doing 70 it actually says I'm doing around 85

I'm on 195/40/14's :(

i fucked up my needle position when i put my white dials in so wen it says i'm doing 30 i'm actually doing 50 lol

Mines still accurate, If anything its got more accurate, The speedo says 70 the gps says 69/70..

I'm on 155/70-13 on the front axle atm, and my speedo reads literally 1 mph under all the way to 110-ish.

Sounds like my speedo wont be as far off as i believed ..

iff your 1.0l tboyk gets to 110Mph then I'm sure mine will get there all good as I'm sure i have done more to mine than yours ..

Not that top speed maters i hardly ever drive fast .. wanted to get home rapid on sunday tho had things to do ..

It was downhill

It was downhill

Haha fair does man fair does ... Downhill is a bit of a poor indication ... betxha dash was bouncing up and down and everything ... lol .. The engines so dont like going that fast do they ...

Mine can keep that speed on flat and a ton uphill .. dont know what it will get to downhill always hold off when the dash starts to wobble and the revs go crazy ..

your 1ltr is freakishley quick tho mate!! you was keeping up well with us on the way down!! and managed to blitz the barry corsa haha!!

For all your tyre calculating needs Stevie. Tyre difference calculator is about a third of the way down but site full of useful info.

Par example: Standard Mk3 GT tyres: 165/65/13 - My New Tyres: 165/50/15

When i'm doing 70mph my actually speed is 70.17mph which is by the by.

Hope that helps.
