Range for both front sides is from -0.8° to 0.2°, the halfway point would be -0.3° according to your printout. They’re both within spec, but ideally you want both sides to be equal.

do you have smooth roads? we have strong rutting this contributes to wear

Thanks! I'm considering having the shop adjust the right side to match the left.

Mostly smooth. SoCal doesnt get a lot of inclement weather to cause potholes, but we did get a exceptionally rainy season back in 2019. We've repaved a lot of those roads in 2020 due to the lack of vehicles on the them.

The key oddity about these alignment sheets is that on stock cars like yours it is only possible to adjust for toe. Caster and camber are static which is why I wondered about your pothole incident.

Like I said, nothing gravely extreme by any means, but that slight uneven wear will persist.

I was doing some research and was surprised there was no camber adjustment at the front, despite the numbers changing with each alignment. I guess the toe tweaks helped.

Looking back at my records, the first signs of problems was early 2019 when we had some serious rainfall and potholes. I do remember hitting one fairly nasty pothole that season.

Hi there, i haven't changed my tire from the first time i bought the F30 (buying from new in 2013). It's Bridgestone Potenza RFT.
My question is should i change these tires?
My mileage is only 24.000+ KM and i rarely use the vehicle for long trip, and also i don't like to speeding too.

Your tires are 8-9 years old. I would change them.
Google dry rot.

[F30PETROL2013]

Actually i have plan to change these tires to non-RFT tires. Is it true that it's more comfortable than those RFT tires?

[chowser51]

I always get rid of my runflats as soon as I can.

Definitely improves the ride comfort.

Most folks will say RFTs have a harsher ride and they ditch them when they can. Now I have had good experiences with RFTs over the years and continue using them. I just put on a pair of Michelin 4ZPs RFTs on my 340. So far they have been excellent and in my subjective opinion quieter than other RFTs. I have a variety of vehicles some with RFTs and others without and for me I dont hear a difference. That is crummy bumpy roads are loud on all vehicles and smooth highways and roads are quiet on all vehicles.

Now with that stated, I have not compared tires on the same vehicle back to back and obviously these are just my opinions. I also, as many of us do, change tires when they are nearing the end of their life. I don't know if this happens with all tires, but mine get louder and louder as they get worn, then when you change to new tires everything is great and they seem quiet and to provide a better ride.

Cheers,

I put about 1K miles on my AS4s. Coming from the Pirelli RFTs they are a night/day difference. Road noise is nearly non-existent, imperfections in the road are subtly muted, and handling is much improved. Road noise is no longer clashing with the radio and I find myself tuning the volume lower and in a much quieter cabin. Rattles and other NVH have all but gone away. In high-speed on ramps you can tell the car is much more planted and no longer teetering on the edge of grip.

Bought a slime kit from Griot's Garage that is OEM approved and stashed it in the underfloor compartment of my trunk. Although I'm considering building a full-size spare kit for use on long road trips.

To be fair, I also adjusted my seating position around the same time to be as low to the floor as possible, fully upright, and closer to the steering wheel. So this may have factor in how I perceive improved handling.

Well, tbh comfort isn't the main reason for me to change to non-RFT. Here in my country RFT tires cost four times more than non-RFT tires lol. That's why i think i'm going to go with cheaper and more comfortable one.
