Looking for tread depth advice.
Last night I enjoyed the warm, caring embrace of a blowout on my 4.8is. There's nothing quite as charming as changing the tire on the side of a busy freeway at night, kids in the car, 24 degrees out, without the benefit of a proper jack or even gloves. It was magical.
I've spent a good part of the morning chasing a replacement tire and need some guidance. I'm running
275/40/20 Michilen Lattitudes. They're the only tires I've had on it so I don't have a lot of basis for comparison. They seem fine. Bit noisy, not ideal in snow but such is a summer tire.
Only one shop in the area can get a replacement for me, and only new. My other tires are at a ~6/10th tread depth, so about ~50% worn. If I replace just the one am I going to run into any risk of harming the AWD system, or is this a tolerable variance?
