BMW Tires -?

Question

I am looking to put on winter tires on my BMW 525i. The current size is 225/55 R16. Will 230/60 R16 fit ok?

I just looked at the tires again and realised that it is instead 235/60 R16 and not the 230/60 R16 i stated earlier! Again, I would like to know if it is advisable to install these in place of the 225/55 R16 tires I have on?
Thanks

Answer 1

It might fit - you would have to mount one to a wheel and test fit it first - but why on earth would you want to degrade the performance of your car like this? There is simply no logic whatsoever in your tire size selection.

The 225/55R16 size offers a much greater selection of winter tires, there is no concern about it fitting your car, performance in snow with the narrower tire will be better, and it won't throw off your odometer or speedometer readings like the bigger tire will. There are simply no advantages to using 235/60R16.

Answer 2

That is a matter of how much clearance is around the tire. The first number 225 is the width of the tire, 225 mm. the 55 means the tire is 55% as tall as the tire is wide. 55% of 225mm, from rim to ground. The r 16 is the rim size. The 230 /60 will be wider and taller and you will need to turn your wheels all the way to the right or left and physically look for space between wheel and suspension or other parts. Also remember that when you hit a bump the wheel will travel up and down.

Answer 3

They come close, but due to the strut design on most modern cars, the fender is no longer the deciding factor if a tire fits. The first number in the tire size is actually the tread width measured in milimeters. in your case your original tire is 225 mm wide. The second number is the ratio of the first number determining the height of the sidewall of the tire. So again 55% of 225 = 123.75 mm from the mounting edge of the wheel outward. So the difference in the two tires in overall height would be 28.5 mm or just under three centimeters. If my conversion is correct, just over an inch.
