Tires (Summer/Winter/All-Season)

Is DIY solution - find out a weight of that green crub balancing accessory and using epoxy glue a LEAD strip from regular balancing balance and glue a crub from behind a rim permanently on 4 rims and forget about it .You can balance wheels any time you desire! Just cut accordingly to achieve a desire weight and show a finger to BMW .Thanks God I own 8 regular rims like cars using for more than century.

 

I just weighed my Power Spoke balancing accessory: 75 grams. Contact @Rexsio for blueprints of DIY solution.

 

When I look at a picture of that rim I’m seeing about 6 “ of lead and opposite side about 2” this is very unhealthy rim .I’m not provide blueprint for that that’s why we call DIY only for skillful owners is idea I can’t shame BMW for such poor design .

 

Well, the balancing weight can't be mounted permanently because then the wheel would be unbalanced when the wheel cover was re-attached. The skillful owners who don't want to spend less than $30 for the accessory will have to make a 75-gram weight that snaps into the same hole the BMW balancing accessory snaps into (see photo above).

 

You obviously balance a rim with green 75 g . Weight than on pic. You provide on opposite side when a tool was removed you can see so big weight of LED to counter balance that 75g.How do you feel if that rim is balanced good when you see such big weight there?

 

Fortunately, my Power Spoke wheels came balanced. Because I run with Loop Spoke wheels 364 days of the year, I won't have to worry about testing my Power Spoke balancing accessory. But I have one if I (or the next owner of my SE) ever need it.

If you look at the bottom-right photo in my above photos of the accessory you can see the considerable number of weights required to balance this designer's-dream wheel. I'm sure the engineers laughed before someone told them they had to create a balancing accessory to make it work.

 

Are there any recommendations out there to rotate tires more frequently than tire manufacture guidance on a Cooper SE? Mine are Goodyear Eagle F1 tires and just hit 3,000 miles.

 

I rotate every 5k. Easy to keep track of that way, but I'm also running nearly 30k miles a year. I notice quite a bit of additional wear on the fronts, most likely due to the torquey nature and my heavy foot. The outer shoulders on the front also wear pretty quick, but that could also be due to attempts at driving on 2 wheels lol.

 

Although the load may be fairly evenly distributed and the traction control prevents you from really roasting your tires, regenerative braking relies on only the front tires.

 

Hey I'm considering the Firehawks too. Somehow my Prime3s wore out in 5k miles. How many miles do you have on the Firehawks now and how's the performance?

 

I also have the Firehawks. My Ventus Primes didn’t last either. I have not had the new tires on long enough to determine wear. However the car handles much better in my opinion. They are pretty darn good in that regard. I did see a noticeable decrease in range, maybe 3-5% if I had to guess. I guess that’s a trade off for a grippier tire. Overall I’m pretty happy. I have a longer range EV for out of town trips so I’m less concerned with range these days.

 

Awesome, thanks for the info.

 

I think I got about 15k out of my hankooks, which means I have about 10k on my Firehawks. They're definitely grippier. It seems like I've taken a hit on my range, but I had them over winter, also. I like them, especially for the price I paid.

 

I put Yokohama AD09s on and am really happy with the performance. They are a road legal semi slick, with very hard sidewalls. The handling is awesome, but I think they would be a summer only tyre in the northern hemisphere. I don't know how they would compare against the firehawks. Awesome tyre.

 

I went through several pairs* of the now-discontinued progenitor of the Advan AD09, the S.drive, on my heavily modified smart fortwo 450 cabrio. In a 195/40-16 size, combined with a 22-45 mm drop on the Bilstein B14 suspension, the ponderous, comically-under-powered smart cabrio became a go-kart, a tactical weapon on twisty roads. I have yet to drive a stickier street tire. I could see myself getting the AD09 at some point, but probably after the warranty period ends, when I might get the KW cool-over setup.

*I mounted these to a set of identical-width Michalak/Brabus wheels with significant offset stagger, so the rears wore twice as quickly as the fronts. The DSC on the smart wasn't in love with the setup, and needed a hair less diameter on the rears, so the fronts became rears after two summers (~16,000 km) and the fresh pair went on the front axle.

 

Do you know if 205/55/R16 have any fit issues on the stock 16" rims? I'm mostly curious if the added width would rub against the suspension or the like.

Thanks!

 

Sorry I wouldn't know the answer to that.

 

thanks anyways though

 

The S.drive was a 300TW tyre. It was replaced by the Advan Fleva V701. I have V701s on my R53 and really like them. They are European C rated for rolling resistance. Pretty good for so much stickiness.
If I change from the stock 'kooks, they'd be very high on the maybe list.
The AD09s are 200TW and even stickier than s.drives or V701s. The AD08s are decent tyres for track and reasonable for autocross. I wish I was as quick as the guy in a 90s Camaro on AD08s... The AD09 is their successor. The ultimate yoko autocross tyre is the A052.
