Tyres, brand and sizes: MA-Z1 drift, 452, VUS

[Mctwist]

I've been quite keen on the maxis ma-z1 drift tyres for a while now but they don't come in stock sizes. Reason is based on my driving style

So I'm thinking about 245/45/18 on front and 265/35/18 or 275s on rear.

Am i looking at a huge combined rolling error with this setup?

Will it muck up the handling?? (something I'm more concerned about)

 

Or would people recommend keeping stock sizes and going for the ultracs or 452s?

 

Many thanks!
