[m5dream]

Hello just purchase my first bmw. My dream car 2016 M5.
It’s lowered on KW HAS. Previous owner said he lowered it and our new tires on 15k miles ago. The front tires are shoot on the inside. Rear are ok he just did alot do but ours looks like.
Is this kind of wear normal for 15k. How can this be resolved ?
What are the original rear tire sizes ? Currently I have 295/30 I was thinking of going 285/35

What kinda coolant do these cars take ?
What kind of power steering fluid ?

When I start the car the ac turns on alway how to I change that setting ?

And any advice u guys can give me I will take it.

With the lowered suspension the neg camber has become too aggressive or was made like that, so needs full geometry check and adjust to dial it out.
Standard tyre sizes are 265.35.20 front and 295.30.20 rear, fitting 285's at the back will reduce grip and affect handling, some owners have fitted 305.30's on the rears to increase grip.
Recommend 50/50 mix with BMW a/freeze and distilled water for topping up.
P/steering fluid is Pentosin CHF 11S or Titan.

Sounds good I purchased a new set of factory sizes from Costco basically 2K so I will get them installed and then do a alignment

Yeah they're not cheap, the Michelin Pilot Sport 4S are the ones some bp members tend to go for but it's your choice.
