I cant seem to find the answer but.. Im going to buy new rims and tires, but I am a little confused on offsets .
- Im getting 20's
- non-staggered 245/35/20 all the way around
I was wondering what size rims can fit on these tires and what offset i should get that would fit on my car...Thanks in advance

 

245's will fit on rim widths of 8 to 9.5" I'm running 19" by 8" rims with 245 series tires and they fit perfect. I don't know how wide you can go with 20's, that's a function of your offset and width. As for off set, I run a +30 on mine and I get a nice flush look. I can't get a finger between the tire and fender in the back. With 20's, you may want to run +35 or roll the fenders in the back.

How about some of you other seday guys chime in?

 

I run 4 rears coupe 19" 8.5 wide which have +33 off set and they run very nicely flush to the body. I also run 245 but with profile of 40. Try the following chart, it will give you a better perspective:

 

Not too sure about that chart, I'm running +30 and 8" rims in the back and it's just inside the fender line.



According to that chart, they shouldn't fit.

 

That's about right. Look at where it says "8.0 +33 - OEM 17" 350Z/G35 Coupe Wheel (R)" The wheel should be inside the outside fender line.

 

so what offset range should i be looking at for a perfect flush look for 20" by 9" and 20" by 9.5? cuz when i buy my next set of rims they're gonna be either 9 or 9.5 in the rear with 245/35/20 i wanna know what range of offset is the best for the tire to be even with the fender and the rim pokin out
