I just purchased a 2008 LR3 SE V8. I need new tires. The manufacture recommends 255/60R18 Tires. I have a great opportunity to purchase brand new 255/55R19 with Land Rover rims. I am not familiar with tires. Will the R19's fit on my car? The lug nut pattern looks identical to my rims. I am assuming the difference between the R18 which I have and the R19 is that the rims are larger on the R19.
