53 offset

[fullout83]

i am looking at a set of rims that have a 53 offset. now this is .5 bigger than our stock rims. would they fit? or what can i do to make them work?

1mm more offset isn't .5 bigger. .5 of what?

I've been wondering the same thing as you. I'm going to be buying a set of 18x8 wheels and i'm trying to get as much rubber on them as possible. My goal is a 245/40/18 so i'm also wondering would an 18x8 with a 53mm offset allow a stock MS3 to run 245/40/18 tires?

Yes.

No.


Fullout, wheel offset refers to how far inboard/outboard the tire ends up relative to the wheel hub. Stock offset is 52.5mm, so your 53mm wheel will place the tire 0.5mm farther inboard (closer to the strut). This will not make any noticable difference.

Squabbin, some people have run 245's with luck, but on an 18" wheel, 245 is a stretch. You'll have more luck on a 17" wheel. At the very least you'll have to roll your rear fenders (I plan to roll mine when I install 235/40/18s). Again, 0.5mm in offset is so slight that it will not make a difference in packaging larger tires.

Both of you guys might benefit from the following site: Wheel/Tire Size Calculator. Note that 52.5mm offset isn't even an option -- 53 is the closest available choice.

dont forget you can always have rubbing issue in the inside of the fender with a wider rim and more rubber

^^right, I think that's why squabbin is wondering if et+53 will decrease that risk, since higher offsets move the wheels inboard.

Technically, a 53mm offset wheel will increase the distance between the tire and the inside of the fender, but only by half a millimeter, which is negligible. It will not compensate for a 30mm increase in tire width (215 to 245)

Ahh gotcha. For some reason I was under the impression that the stock rims were a 50mm offset so I thought that the extra 3mm of offset would help out enough to not rub (at least i was hoping that). Since they're 52.5mm offset i see what you mean especially since I plan on putting on the cobb stage 2 suspension later down the road. My thoughts are this now: I'll do an 18x8 with minimum 50mm offset, 235/40/18 tires and roll the rear fenders in preparation for the cobb stage 2 suspension which lowers the car 0.9" in the rear and 1" up front. Sound good??? I actually really like the 18x8" stock RX-8 wheels, they are 50mm offset however i havent yet been able to find how much they weigh which will aid me in my final decision.

when i said .5 bigger i ment it as our stock rim is 52.5 so a rim at 53 is .5 bigger that 52.5
