I'm planning on getting a Passport Touring soon and have been doing some research on all-terrain tire and wheel combos. I wanted to post what I've found so far for everyone's reference and to also get some feedback from the group (first time looking into this stuff and not an expert by any means, so all comments welcome). I appreciate what everyone has shared so far.
My understanding is that a 30" diameter tire is the largest size that will fit without rubbing in a stock configuration.
Stock tire for touring and elite: Continental crosscontact (265/45R20 104H) revs/mile: 707 dia: 29.4"
Largest AT tires in 29 to 30 inch range for 18 inch wheels:
Nitto Terra Grappler (255/60r18) dia 30
Nitto Ridge Grappler (255/55r18) dia 29
Continental TerrainContact A/T (255/55/r18) revs 716 dia 29
Continental TerrainContact A/T (245/60/r18) revs 702 dia 29.6
Yokohama Geolander A/T (255/55/r18) revs 715 dia 29.1
BF Goodrich KO2 (255/55/r18) revs 717 dia 29
General Grabber AT2 (255/60R18) revs 692 dia 30
hankook dynapro atm (255/60R18) revs 692 dia 30
I've been looking for 18" all-black wheels that will fit and this is what I've found so far:
KMC km708 bully
KMC km716 nomad
Black Rhino York
Black Rhino Overland
I'm currently leaning toward the Terra Grapplers on KMC bullys. Anyone have experience with how much road noise to expect from the Terra Grapplers? From what I've read online they are on the low end of noise for an all terrain tire. I currently run Goodyear Duratracs on my land rover for reference.
