maybe shopping for new rims, what offset to get?

my car is lowered about an inch front and rear, what offset do i choose on the new wheels? since it's my daily driver, i would like it to be 100% rub proof against the inner fender.

If you want to not rub but able to have a nice aggressive look. Get the size 18X9.
18X9.5 would work as well, but you'll want to run a bit smaller tire and it also depends on your offset.
Offset from +22-30 will work no problem on a 18X9 or 9.5 rim. If you want to get a big size tire, from 265 and up, you'll want to roll your rear fenders, as well on the front, but the fronts you won't have to. If you don't roll the rear fenders and you run big tires, you'll just scrap everywhere you go and eat the crap out of your tires, haa.

Well good luck on your search.

The offset you need will depend on the spoke type, whether it's concave, straight spoke, etc....

I went 18x9.5+28 for that reason. 265's are more-or-less flush. You could go 9 to tuck them in farther.

apologize for my newbieness, but does that mean +22 to +30 or +20 to -30? the larger the number the closer to the fender, correct?

The opposite--the larger the number the closer it is to your shock. Most guys are buying 18x9.5+22 and putting 265's on them. This requires rolling your rear fenders in most cases. The rpf1's that are so popular are +15 and always require fender rolling with 265's. If you go 9.5 at +28 then you're just about flush with 265's. A 9 in the vicinity of +28 would be in the wheel well but you might want to stick with 255's or a tire that runs narrow in 265.

The stock rim is 18x8.5+38. The rim is measured in inches but the tire & rim offset is in mm. For the rim & tire width half of the added width will go inward and half will go outward...it's not too hard if you think about it the right way.

thanks for clarify that for me. i think i'm gonna go with 18x9 +25 and running 255 tires. is the difference between the +25 and the stock +38 that visible?

Just picture a flat spoke type wheel.... a "0" (zero) offset will have the spokes in the middle of the entire wheel.

+20 will push the spokes 20mm towards the fender inside the wheel barrel.

-20 will push the spokes 20mm towards the strut which will push the wheel (barrel) out towards the fender.

Generally the lower the positive (+) number is and also the bigger the (-) negative number is.... will have a bigger lip and or more concaveness.....

Very noticeable difference between +25 and +38.

I would recommend getting 265 tires since it has a closer diameter to stock
