Need wheel help! Bought some 15's...

[sammyboi]

Right, i bough some 15 inch alloys off the bestest place in the world....ebay! But im unsure to what tyres i will need so i dont throw my speedo off too much! I think ive got it right here but need confirmation:

Current wheels:

13" x 5J
155/70/R13


New wheels:

15" x 6.5J
195/50/R15

Is that alright? or would i need 195/45/R15?

Any help anyone can give here would be much appreciated!

Cheers,
Sam.

How do you know your speedo is correct with the 13's on? On my road Angel it tells me that im near perfect...if not 1 mph out and im rollin on 17's?

with the stock tyres, mine was 2mph out but with wider tyres at the same profile according to gps it's bob on correct

I'd ignore the speedo and concentrate on the handling! Get the best tyres you can afford. You could always buy a GPS speedo if you want an accurate reading.
