how big can i go !!!!!

[James_Mould]

19's would look good but are a bit impractical for every day use. Would make a good show car though.

looks like i will be sticking with 17"s then cheers for the help guys

19s on a calibra, defo, 18s look nice without a kit and lowers, but calibras with 17s and kit look too small TBH.

19's with 35 profile are tyres are the same radious as standard 16's give or take a mm or 2. Like others tho, I woudln't recommend them for daily driving, I went through tyres more than petrol

Do you want performance or looks?
17x7.5 or possibly 8 for the former, 19s on rolled arches for the latter.
( or 15s if 1/4 miling is your thing ).
