Help with wheels and tyres

[viola2572]

Hi I want to know what off road tyres and wheels you guys are running, I have a
BMW N54 engine Twin-turbocharged, 3.0-liter, straight-six petrol engine 300 horsepower and 300 lb-ft of torque in its factory state, going to put a Hp845 gearbox on it not going to tune it.
but how have you guys managed to stock ecu or stand alone?

I'm running an older BMW engine - M20 stroker 2.8 (M52 crankshaft) on stock Motoronic ECU with a 2.8 tune chip. It's probably around 200 ish at guess maybe a bit less.

I've recently changed my wheels and tyres from 15's (with 205/60/R15) to a set of staggered 16's Maxilite BBS RZ RS Style - with Michelin Pilot Sport 4's - 205/55 R16 on the front and 225/50 R16 on the rear. Significant improvement over the old tyres. I like Michelins have been running the PS4S on my daily for years now.
