Sizes of wheels
Just got my X3 2.5i, it came with the alloy rims:
Style 148, 235/55R17
If I were to changed to the:
Style 114, 235/50R18 (front) and 255/45R18 (rear)
Will I get a significant drop in pickup / acceleration performance?
A handy lil'link below to do some arith on wheel size, etc.
With the diff front/rear, you can't calc Exact, but the "rear to rear" diff
you are wondering about is minimal. Doubt test equip could record
a diff 0-60 speed, etc. Would look "cool" but not impact much, imo.
235/55-17 5.1" 13.6" 27.2" 85.4" 742/mi 60MPH 10000mi N/A
255/45-18 4.5" 13.5" 27.0" 84.9" 746/mi 60MPH 10052mi -0.5%
Thank you very much for the reply.
Do you have any recommendation for tires?
Where I live is summer all year (dry mostly), with a bit of short rain showers. Quieter tires will be good!
You are welcome, Simon.
No clue on tire brands, but if you don't get some ideas/opins in this thread,
repost your tire brand question in new thread.
I loved Singapore the few times I was there!
One of the problems about Singapore is the cars are hugely expensive, and there are very few car specialists / dealers who really know the stuff, including the BMW dealers themselves. The sales person didn't even know if my car had Cruise Control (not that it is important in Singapore)!
I just bought a 19" rim with Pirelli PZero Rosso Asimmetrico 245/45/19, pretty good. Quiet and comfort
