My car is finally ready for new tires so I need some advice on what to get installed.

I'm running what I believe are the 18" stock OEMs Style 189. I have RFT on them right now but will be losing them. The weather here is warm during summer, and no snow in winter.

1) Pilot Super Sports or A/S3s?
2) What are the largest tires I can fit on the stock wheels without any rub? Stock is 225/40/18 and 255/35/18/

Currently, my wheels are evenly worn in the back. The front are at about 4-5/32 on the outside and center but at the wear bars on the inside. Do BMW tires normally wear like this or is my alignment really off? I heard that BMWs are supposed to wear on the outside in the front.

1. both the PSS and PS A/S are great choices. It comes down to preference. I use the A/S 3 tires and they are great all around but if you want a pure performance tire go with a PSS.

2. You can run a 235/40 and 265/35

You need to start considering the condition of the roads you are traveling on. If there are a lot of pot holes and the like, I would not be running 30 or 35 profile tires. 45 is a much safer profile tire for pot hole type roads.

Sounds like you have the m-sport option on your car. That is a nice set up. The tires wear inward because BMW's are cambered inward, which helps the corner better.

What size tires are you looking to get front and rear?

I am guessing 245/45/18 front

255/45/18 rear

Goodyear F1 Asymmetrical All-Season

I like the Goodyear's because they are better in light snow than Micheline A/S 3

Therefore, you don't get caught with your pants down in 2" of snow during November right before you put your winter tires on, or right after you just took them off in March.

The 45 Profile will ensure you don't blow out your tires by hitting a pothole etc. 40 and below (especially 35 and 30 just begs to destroy an expensive set of tires and rims)

If you live in an area where snow is not an issue, then by all means consider the Michelin Pilot Sport A/S 3's. They are without question the very best tires for this car.

I live in Michigan. The roads are horrible (Riddled with potholes) and the winters are COLD. I have a 45 profile on my tire; I do not use a run flat. I have never blown out a tire (nock on wood) in the 5 years I have owned my 335i.

You know that the second number is just a percentage of the first right? You can't make a broad statement about a 30 series tire without knowing the tire width. 235/45 = 235*0.45mm tall.

Pss is more of a dedicated performance tire, where as the a/a is probably a better all around choice.

With regards to tire wear in the front, bmw doesn't add enough negative camber to our cars and so as you corner you tend to have the outside tread of the tire doing the majority of the work. This can be fixed with camber plates or coil overs that come with camber plates.

I do not feel the width has anything to do with a tire's % of blowing out or not. Plain and simple, if you run a 235/30/18 or a 235/35/18 vs a 235/45/18. The 235/45/18 is less likely to blow out due to a pot hole. No question.
