Yes I'm a noob but believe me, I read many hours since this weekend about that since I shop for new rims. I just sold a 2007 Corvette (and still have my 2004 SRT-4 for sale) and I bought a used 2008 WRX Sedan. It has winter tires on the stock rims so I plan to buy new rims and tires for the summer.
I was suprised by all the offset question and discovered that our choices are greatly limited.
Yes, I read the Wheel / Tire FAQ and many other thread before posting this.
I learned that the stock offset is 55 and since I want to go with 7.5 width, I assume that the new "target" offset is close to 50 +/-3, So I need and offset between 47 and 53.
I want to buy those FD-05 on Home - Discount Tire Direct
but when I enter my car, the wheels it recommends me are 18x7.5 with a 45 offset. The FD-05 also come with a 53 offset, which seems ideal to me.
So, who is right? The giant web site that sells a few millions of tires a year or the newbie that didn't really know what was the offset a week ago.
Here's the 2 choice I'm talking : 18X7.5 5-100 53MTB (what I thinf is good) or 18X7.5 5-100 45GMM (website automated recommendation).
I would propably put 225 wide tire on them. I don't plan to lower my suspension for now (even if the gab is really too big for my taste.
If necessary, they also offer 17X7 5-100 50GBM for that model (plan B).
Plan C are Enkei ZR1 17x 7.5 with SBC finish, which look very good but with their particular design, they look more like 15" and 17"
Thanks a lot
