Yep, that rear looking like a doughnut compared with the front is what triggered all this and it's been eating at me for almost a year now! You are seeing correct. The specs are: F: 255/35 18x8.5 +25; R: 285/30 18x10 +37. No fender rolling and no rubbing at this time. The fronts currently have Conti's SportContact-2 and the rears G'Year Eagle F1-GS-D3. I found both tire types on e-bay, new for a decent price. Love the G'Years but may have to go with the Contis to keep F/R same tire type - not that it matters at all!
