Hey guys,

I'm just looking for some input on what setup would be most effective for my needs:

• No Rubbing
• speedometer still accurate, or at least very close

My car is a 2010 335d, base model with stock suspension. I know there's pros and cons to square vs staggered but I'm looking at a square solution right now.

I've done some searching here and I arrived at this setup:
245/40/18 all around with PSS

Is that a solid setup for a stock vehicle, with no rubbing/issues?

I've also seen these recommended for square setups:
245/35/18 all around
255/35/18 all around

Finally, when it comes to wheels, I really like the VMR 710s - what's a reasonable price to expect to pay for these? I sent an email to their CS on their site but it's odd they don't have prices listed. Anywhere else to buy them? Anything to look out for?

oh and for OEM wheels from BMW, where do people normally acquire those? Private sales or auctions (eBay etc)?

Check out this link! It's an excellent source when trying to figure out the speedo variation vs. your stock tire size

Rule of thumb in the wheel/tire industry is to keep the variation below 3.0%

It's better to be over by a little bit. The stock speedometer is off by 3mph. I would go with 255/40/18 or 245/40/18 all around.

It's a decent setup. Pros is you can rotate. Cons is looks and handling. You'll have higher profile tires. Good for potholes, bad for handling. If I was in a snow area I'd use stock rims for snow tires for the winter, and 19" aftermarket Staggard for summer. I've got 235/35/19 front and 275/30-19 rear on 19x8.5 and 19x9.5 wheels. Pretty standard setup. I've had 245 front and 265 rear too over the years. I'd go to tirerack, plug in your car, and look at the different size options. I'm on tire set number 9 now. As for the wheels, look at the vendors for decent prices. As for oem wheels, a replacement I'd get from a yard. If it was repairable I'd do that first. I'd never get a set of BMW wheels new from them. They're about 300% higher priced than what they're worth.

Thanks for the suggestions, you wouldn't happen to have pics of either would you? Is that what you're running with now?

thanks for the tips man, much appreciated. I like the look of 18s a little more than 19s but I see what you're saying. When you say cons are the looks, do you mean because they're not staggered or is it something else?

With my setup on my body car I car get an even 4 wheel drift so I know the amount of tread is balanced front to bsck. Less rear rubber with stock size I would get oversteer. To put it a way I can explain it, and I'm sure some tire guru will jump in and correct me somehow, 19s eliminate some of the sidewalls which gives less body rolls in the turns. However, 19s still soak up most of the bumps fine for everyday driving. They were an optional size from bmw so they aren't pushing the limit. Some guys go 20s but then you have to be carefully as you have very little sidewalls. Bending a rim and harsh ride show their faces really quickly. Stock I could chirp 3rd but with 275 and a juicebox the added traction makes 2nd chirps rare. Most guys go to 19s and most guys pics on here are 19s.
so the benefits of 19s over 18s is less body roll, better traction, visual appeal. The benefits of staggering is more balanced traction minimizing oversteer and visual appeal. The benefits of 18s is less expensive, more resistance to damage from potholes. The benefits of all bring the same size is you can rotate your tires and get a little more mileage out of them. Gotta weigh the pros and cons of both to you. If possible I'd look at 19s on one in person and drive a staggard setup to feel the differed. For me it was a no brainer. I prefer the performance over other benefits.

As for the cons of looks, smaller sidewalks and more beautiful rims filling the wheel well has been the trend since the 60s. Most muscle cars came with 14s. Performance cars in the 80s had 15s. By the. 90s 16s were taking over. My corvette, 1992, had 17s. Now 18s are a standard performance size with 19s being the hot setup. 19s will standout vs 18s aesthetically. A car with 18s next to one with 19s will look less powerful and luxurious. On our cars, going to 20s in my opinion get to that point where it stops looking integrated with the rest of the car and shouts look at my rims. Proportionally, I they're too big starting to take on the "donk" look which to me looks silly. 20s do however work on a 5 or 7 series. Finally Staggard look also imparts a performance and balanced look to the car. The fronts of our cars are smaller than the rears. Tires larger in the rears work well for the styling balance wise. They also impart a feeling of added performance. You need big rear tires and wheels to get traction with this beast is the feeling it shouts. Reality is this is true to some extent. This is why you'll find Staggard setups on most performance cars today, Ferrari, Lamborghini, corvette, viper, etc.

wow, thanks again for the detailed info. This car would be my daily, but only during spring/summer, I have an old beater I'd drive during the winter so maybe the staggered setup would be ideal.

So you would still recommend a staggered setup on a bone stock 335d?
Something like:

235/35/19 and 265/30/19 ?


and that setup on a stock car won't cause rubbing or any issues? speedometer still works? Those are my biggest concerns.

nice

thanks

That setup looks great but again I have a different body so check with other e90 owners to get correct offset etc.

thanks dude, I appreciate the help.

Tire sizes are virtually useless when confirming wheel fitment. Wheels are the #1 driver in terms of whether you will rub or not based on their size, width and offset. Find wheels first and then focus on tire size.
