xDrive 245/45r19 tires
Hi all!
New X3 owner of an used 2011 model, xDrive35i and first BMW vehicle ever. I was reading through threads trying to research but couldn't find an exact answer, was hoping for everyone's opinion. Like a lot of owners, I will be moving away from the run flats but I was also hoping to go from the stock 245/45r19 to a 245/50r19 tire. Would that detrimentally affect the sensors? It will be a change the diameter +3.2% Thanks for all your input! |

First off, I'm happy you've decided to get rid of the run flats. It will be a completely different vehicle after you do that. Ride smoother, better acceleration, shorter stopping distance, and better fuel mileage. That's a rare and expensive tire size though, and yes it will throw the speedometer off (it's -3mph from the factory so it might actually read correctly haha).
Why would you want a larger sidewall? It would make the car handle worse. Trying to get the car to have a smoother ride? Getting rid of the run flats fixes that, no need for a larger sidewall. If you drive A LOT of miles AND in mild snow during the winter the go-to tire is the General AS-05. If you live in a part of the world like I do, Florida, and zero snow ever, don't care if your tires are bald in 25k miles cause $600 for a new set is pocket lint and want maximum dry and wet traction with outstanding cornering making the X3 feel like a proper BMW? The Firestone Indy 500 is the best tire you can put on an X3. Both in 245/45-19 size. Oh, and being a 2011 35i? Get ready to fork out $1600 to replace the water pump any day now.

Agreed to the Firestone being a good tire for the money (I have them on my 135i), also to the general lack of reason to go to a 50% profile over 45 (is there a huge price drop or something?).

Looks like that would drop the total price about $100, I guess that's a decent amount. It's not a huge difference in sidewall height and I can't think of any particular reason the car itself would notice. You guys would have to keep in mind your speedometer will read a touch low in regards to getting a ticket for speeding but even that's somewhat unlikely.
That Continental should be a decent tire, and isn't directional (I don't think it is but you should verify), meaning it'll be easy to rotate the corners around from time to time, which is a bonus. |

For family hauling I'd def get the General AS-05. After all, it's BMW not a Grand Caravan. I would have got the 28i it would be more reliable.
