I'm not sure what to do!!
 

I've won a bid on ebay for some Buddy Club alloys wheels for £255.

They were advertised as 17's, now the buyer is saying they are actually 18's!

I really dont want to slow my car down, will it?

And will it raise the car up and look stupid? :confused:

Plenty of people run 18's, work the sizes out using this site..
TYRESAVE: Tyre Size Calculator
and see what the gearing works out like....

Generally going up a size in rims means going down a size in aspect ratio. Eg 225/45/17 becomes 225/40/18. This keeps the outer rolling diameter as close as is possible to the original As said previous use the link to the tyre calculator.

Big alloys/tyres (heavier) will slow accelleration in theory, but you'll never notice it. As described above, you keep the wheel diameter same as standard by lowering the profile (expesnive!). This will make the ride harder and beware potholes!

But what width are these wheels, and what off-set (ET)? Get either of these dimesnion more than a few mm out and you'll either hit the calipers at the front or rub the arches at the rear.

The upside of bigger wheels is the tyre contact patch is bigger so more grip (except in standing water and snow)
