Anyone out there with 18" BBS wheels on an allroad? Iv'e seen them in photos but was curious about the offset and need for spacers. Is caliper clearence the issue or the adj. hiegth? And how about the Tire Press. Monitor system fitting into the wheels? Tire rack said not all wheels will accept the TPMS. I've seen BBS RX and CH wheels on Allroads and those are the ones I'm interested in. I can't seem to find the tire I want(new Goodyear Eagle F1 all season) in a 245-50-17 to fit on the stock double spokes. Only 235-50 or 235-55, and that leaves me either + or - 1/2" in diameter from the stock size. Am I better off going up or down in size? I desperately need out of the 225-55 Goodyear Assurance, THEY SUCK!
