You should have either 4.1's or 4.3's as standard..... have a look on the compliance plate on the RH side of the firewall... it will say on there H233B then either 4100 or 4300.

Either way you shoould be OK as play tyres, but you will notice slower accelleration and braking and increased fuel consumption

You dont NEED to, you may WANT to.

I have a GQ TB42 manual with 4.1's and 35's. I think it goes fine.

I would say since the grenade can be a pig to get going, you would wanna..

but as said, it depends on what you do most of. if its fine with 33 and you tour on 33's leave it.
