Id suggest going to a used tire place, find way better prices... I have all used tires on my car, 2 identical pairs of 245/45/17...2 different kuhmo's. I paid $35 for each tire.

Used can be hit and miss. No warrenty and you have no clue how they were treated or how old they are (dry rot). You might scoop up some cheap. You might have a blow out at 70 MPH and total your car.
Not something I'd personally risk.

you dont have to have different wheel sizes to get different tire sizes.

Unless you're speaking of width

You can go different width front and rear on a set of 4 similar wheels.

I have 20x8.5JJ mega rims and would like advice on tire size. The 225/35/20 rubbed in the front when full turn was made. I have bought 1/3" spacers as well but have not yet tested the fit. I am not sure of the offset and the wheels are universal rims sold by Mega. Can someone please help me. I saw a site that said 245/30/20 was the best size but i cant confirm ANYWHERE. If you have 20's what size tires fit??????

well of course different widths. i had chrome cobra R wheels before the fr500s and had 245s and 275 all wheels were 17x9 and it looked mean just not as mean as my 275 and 315s now
