It would help us if you put a meaningful Location in your details! O-vl means nothing so where are you located? If in Europe use your local website search engines for manufacturer tyre websites. They should include the correct rim width for every tyre size.

I have swapped a stock 3" wide rear wheel for a 4.5" wheel, to go from a 150/80 to a 160/70. That is the difference in rim width required for correct fitment of each size.

 

i recently mounted a 140 70 18 on the front of my 04. could have gotten a 150 in there but would have required me running a rear tire in the front. used a Pirelli tire and it fills the fender..

a 160 will fit but as grbrown says, you need a wider rim.
