    Just wondering what aspect ratio tyres you guys are running on the rears of your Zeds?

    I've just switched from 245 45 R17 to 255 40 R17 and they are quite a bit smaller in diameter.

    Anyone running a 35 or 30?

    I think going off the 25th AE placards that 40 would be the starndard profile for a 17" wheel.

    I dont recomend 35 profile on anything other than a flat smooth hwy, and we dont have much of that here in vic country areas. I still have a set of stock wheels, with the centre caps, I'm thinking of having them polished up and re tyred.

    you can use the following calculator to compare different size tyres and find the correct equivalent when changing width:
