225-55-16 ?'s

[jmcboost]

I found a great deal on some 225-55-16's for the sawblades I have on right now. What is the physical difference between those and the 225-50-16's I have on it now.

your car will be higher off the ground and your tires will look bigger cause they will be taller

Ok, but will I still have the same width? (that's what she said):naughty:

 

[Clip]

the second number is the ratio to the first number (tire width). so the new tires will be 55% of the width, whereas the stock tires are 50% width. did i do that right, or was i misinformed?

i believe its 55 milimeter sidewall... first number is width in mm, second is sidewall height in mm... last is rim size...

So they should be the same width. Someone needs to come up with a better tires sizeing system.

second number is aspect ratio of tire width to sidewall height, so 225/50/16 is 225mm wide tread and 112.5mm sidewall

225 is the width
50/55 is the ratio of the width that is the height.
Your speedo will be off (traveling 62.1mph when your speedo reads 60)
You will gain 1/2" in height

Alright, thanks for the help and the prompt responses.

 

[westonboege]

ah... the ratio of the width..

And it is 225 mm at the sidewall mounted and inflated but no load.

Who is running a 245/45 on the stock sawblade or 5 star? Pic?

While this is up can I change direction just a bit and ask if anyone has mounted 15" rims on a MA70? Will they clear the brakes?

I only ask cuz I have an almost brand new set of 255/50ZR15 Bfg Comp T/As that have just been sittin. It may look funny but they should stick in some corners too.
