17x9 tyre sizing
 

Looking at buying a set of rotas from ebay. They are 17x9 but the tyres are 215/45/17. Surely these must be quite stretched, what I want to know is if its alright to run these tyres and will it affect performance at all.
Not sure whether the et is 35 or 50, will I still be able to lower it on say tein springs?
any help appreciated.

Yes you will want different tyres. I'm getting 245's for my 9" wheels

Okay thanks mate I did think it sounds a bit silly! Will look for different wheels

I had 235/40/17 on a 9" had a slight stretch
