Tyre advice

[Futureman]

I'm currently running 18' wheels (8.5 front, 9.5 rear) (225 40 front, 255 35 rear) and I'm just wondering what's the maximum tyre size I can get away with to cope with the current state of British roads (plus I prefer a meatier look).

I'm looking at 235 45 front and 265 40 rear? Would this be ok, or will I run into issues? (Running B4 struts and OEM springs)

Any advice would be greatly appreciated.

I think it depends on your wheel offsets too but 265/40 sounds very chunky. Tyres are fine for those wheel widths though…

Would they rub do you know? (Not sure of the offsets, I'll have to check tomorrow.)

Sorry no idea for sure but probably.
Big dimension changes, raising the car and putting the Speedo out. Try this site.
