16" Classic wrx alloys
 

Hi all,

I know it sounds bizarre, but what size tyres can I mount an a classic 16" alloy which would match up with the newage 17" 215/45/17's..? I'm looking at ALL widths and profiles. :wonder:

Obviously I don't want to cause any diff issues, so would any small fluctuation in rolling diameter cause me future diff problems..? :(

And finally, an explanation... the 16's are for use as winter wheels and tyres. :p

Thanks in advance for your help..!!

Shouldn't make any difference to the diff - the important thing is that all 4 tyres have the same rolling circumference (plus the spare tyre).

I suspected that Tim, but needed confirmation to be happy in my mind.
Thansk for your reply, I'm all "confirmed up" now..lol!! :thumb:

This is a good site for checking the difference http://www.miata.net/garage/tirecalc.html

Paul,

Thank you kindly.
Exactly what I was looking for.

Now all I need to know is what is the narrowest tyre I can safely put on a 16" classic 5 spoke alloy.

Should be 205/55/16's I reckon, these came with my dad's leggy before fitting 17's which are 215/45/17.
Same size as the newage cars:thumb:

Classic 16's are 205/50/16
