I saw a couple posts were you guys run spacers too? Why? Any cons?
Spacers give you a wider stance and is mainly for aesthetics. In most cases handling can be adversely affected because of the increases scrub radius and reduced spring rate effectiveness at the wheel which more than likely cancels out any traction benefits from being 20-30mm wider. I found that I did not like how spacers affected my F80 handling characteristics. They look great and make a big difference in the aesthetics and enjoyment of the car in that department but ideally, they should be run on the street and removed for high performance driving on a track. They are also restricted on some track days which should tell you something.

Thank you!

I have a 320 sport line... I don't track or race and I am not looking for performance. Will it affect the handling at a point where I don't like to drive my car and feel it doesn't turn right or something?

I had it on my F80 for canyon runs and did 77 laps at Willow Springs... while it wasn't as sharp with it, it was still very fun and driveable. Granted, I had aftermarket suspension which was slightly stiffer.

I have these tires and they are "ok". They have a little bit of a squishy feeling to them. I got used to them now after a year or so so I'm not noticing it as much. The ride IS smooth, the grip is decent (but not better than more expensive products).

I've had them for a couple years now on my supercharged 350Z, they're decent, especially for the price. Pretty progressive and audible on breakaway. They're basically the next generation of the Bridgestone RE760, which was a pretty good tire in itself. For the price, they're a pretty good consumable for track days. Not as sticky as the more expensive rubber, but they'll take a beating and last a while if you're not racing a clock.

I don't know if that's their policy or just a very anal manager.
The reason I did not do this is because IF I need an alignment, Firestone will do it when they mount tires, the America's Tires around me do not do alignment if needed.

They were 580$ shipped compared to 1200 for the PS4S lol.
I'm putting 500's on next week. If you compare Tire Rack with a Firestone store and assume the additional fees at the store (mounting, balancing, etc) is added to the tire rack price, the store comes out some $20 cheaper. So, why spend all the time & energy mounting yourself if you can get someone else to do it for less (or about the same)? The price from Tire Rack is $558, then add sales tax and installation (using the same charges for these costs as at Firestone) and the total is $725, the "out the door" price from Firestone is $707, and the Firestone store around here has NO issues with putting these tires on my 2017 440i convertible.

I think that's a bunch of bull. Why would you "have to" have a tire that allegedly says you can go up to 186?

You don't "have to" but as you will see if you read these tire threads, some shops/managers/etc will follow certain policies such as not deviating from OEM specification with respect to speed rating, load rating (e.g., XL vs. non-XL), non RFT vs. RFT, etc. One can only assume they are trying to limit their liability.

When i got my PS4S installed at Costco a couple of weeks ago, they called me right after they pulled the car in and asked me if i knew i was installing non RFTs in place of RFT. Of course i said yes (that's the point, lol) and they acted like i was crazy saying that i don't have a spare and would have to get the car towed if i got a flat, but they still proceeded with the install without a hassle.

This is my biggest fear when my run-flats wear out and I move on to some better go-flat tires. Many of the chain tire stores and Costco in this area are really strict on load rating, speed rating, and size matching EXACTLY the OEM specs of the car...regardless if you are moving up to a more capable tire.

I'm hoping a couple local independent shops won't have any issues. If nothing else I'm pretty sure the speed shop which sponsors our local SCCA autocross events will do any tire work I need, but they are an hour drive away.

You can read about the exact tires i selected in my thread here: https://f30.bimmerpost.com/forums/sh...9#post25761679

There were numerous options for different load rating, speed rating, etc, even within the same exact tire size. FWIW, i went from runflat to non-runflat and i also went to a non-OEM size (changed fronts from 225/40/19 to 245/35/19) and Costco installed them without issue. I think i went to a higher speed rating and load rating.

My shop just mentioned it as like a warning, like you are going from this to that, fyi (probably a cya lol.) I was like yeah, no problem I dont think the car can get above 168 any ways. I've never really an issue as i usually just drop the wheels/tires off and just tell them no rush, they arent installing them on the car and seem to not care as much. The benefit of having two sets.


Now back to the tires, I have them on two of my cars. They are more than fine for my GT. Ride quality and handling are both fine for what i do with the car. The price is real nice. On my other car, i will be getting something a bit more sticky as i break traction 1-3 with them. not worried about 1-2, thats going to happen but I want something that hangs on a bit more in 3rd.

Remember to ask about the friends and family discount. It's been worth 15% a few times for me.

And that's great to know that the folks at Costco notice a difference and contact you for confirmation. That's all I was trying to say, it's your car and you should be able to do what you want to/with it.

I'd like to update my response to this. The adverse effects of spacers are minimal with reasonable widths. What will affect handling is changing the ratio of track width front to rear. You can change grip rotational characteristics this way. This is mostly for those who track their car and are going for PB lap times.
