They haven’t been on long enough to be noticeable yet but yes there will definitely be more rock chips. You’ll notice I also removed the mud flaps front and rear (for looks) so that’ll make it worse.

I was worried the +18 might have too much poke, but I'm happy with it. The 8.0" wheel (vs. 8x5 for most RRW) helped a little.
