Would love some advice from experience pls chaps:

Going for some new boots on my 19'' Vogue wheels - was thinking General Grabber AT typres as have had them before on a car with 20'' wheels.

Would you go 255/55/19 or 255/50/19 and or are there any other tyre choices I'm overlooking?

Cheers

255/55/19 AT3, assuming you are doing anything off tarmac. It's the right size, and any reduction in profile will inflate your speedo to the extent it will say 80mph when you're doing 70. Unless you are running with 11 points on your licence, it's pointless IMO. The older I get, the more I realise that people confuse wrinkles for wisdom

I have GG AT3 255/60R19 for their higher load rating and slightly taller sidewalls for outback touring but your spare should be the same size too.

I fitted 255/55/19 AT3 this morning and the difference is spectacular - thoroughly recommend to anyone with the same dilemma.
