Wheel Size Illegal?

[rbrbrb]

hi, I bought some wheels and tyres of ebay for my 2005 ba XL ute (stock 215/60/16). The wheels/tyres I bought are F 225/40R/18 88W Dunlop Le Mans, R 245/40R/18 93W Dunlop Le Mans. Would someone be able to tell me if these would be illegal(also for insurance purposes) in NSW? if so could I and how much does it cost to get an engineered cert.?

thanks

open your door and look at the wheel tyre spec sticker, you can go 2' diameter bigger than biggest rim.

but the ba model came out factory with 18' rims so you should be able to go 20' max
