Ok, I need some basic help here. Trying to understand how the
sizing for wheels go. I currently have the 17x8's on my 4. I'm trying to upgrade, but the TiresPlus I went to said that I couldn't upgrade to 18x9's. So, I'm trying to learn more about my options for upgrading tires/wheels in size. The difference between 17x8's
and 18x9 is what, 1 inch taller, 1 inch wider? What are some things to keep in mind as far as:
offset size?
bolt?
wheel size?
width of rim/tire?

I guess I want a little more of a "deep dish" look. Let me know. Thanks.

If you need to understand tire size.. and rim size.. I suggest the first place to look for is www.tirerack.com

They will show you the proper size upgrade.. as far as the best size for 18" is 8.5 in width on all for. or you can stagger..

Which couple good moderator can help you if you post in wheel form.

Thanks for the direction. I'm learning.....

So, even though the TiresPlus guy says that I can't get 18x9's, there really isn't a can't? I see people in here with 9.5's, so I don't see why I couldn't do a 9.

I don't know anyone with 9.5's up front. You can do it in the back though, or 10s. Up front people generally go with 8.5s up front but I've heard 9s fit. I personally wouldn't want even more rubber or rim weight up front.

here you go:


18x8.5 f+r...if you do not want staggering
18x8+9...bit undersized, but ok
18x8.5+9.5...almost the best fit...
18x9+10...more aggressive, be careful with offset and tyre selection..

offsets +38 to +45 would work, depends on wheel width..
