I'm starting to get my head round it now.lol

I found this web site...... Very useful.

http://www.etyres.co.uk/tyre-size-calculator.htm

It calculates the difference in rolling diameter between your old and new tyres.

This one's better - does stretch too :-) and offsets :-) :-)

Think i'm going to go for 165/50/15

tut tut tut, what is it with all the unnecessary stretch going on these days? Where have peoples balls gone? If for some reason you feel the need to have stretch, get some propper wheels!

Not havin a go at you mate, just puzzled, there have been loads of threads recently about stretch on 6j wheels...

The reason i went with this size is because they have the nearest rolling diametre to the standard. Thats why i've chosen these.

Naa mate 195/45/15 IS standard!

ok thanks. the local garage has just told me the same.

Picked the alloys up yesterday.... looking good.

I now have some vw polo mk4 steel rims with good tyres on that i need rid of....... the tyres were only put on a month ago.

Only want £20 a tyre/ rim.
