The biggest down side to 19" tires is limited availability of 245/55R19 tires because it is not a common size, and a higher replacement cost than for the 245/45R17 tires. -- Ray O (correct punctuation to reply)

From where I sit there are no downsides to 19s. As a general rule of thumb, larger rims are more desirable than small rims. There may or may not be a slight difference in the "unsprung" weight, but I doubt that you would care unless you went to the track, which is not likely with a Highlander. The unsprung weight is the weight of the suspension that is not carried by the springs -- this would include tires and rims, brake components, and axles. Since all of these would be the same except for the tires and rims, they don't really matter very much. The difference in the unsprung weight is the reduced weight of the rubber offset by the increased weight of the material they use to make the rims. It's possible that the rim material can change and larger rims could (in theory) be lighter than the smaller rims -- as a practical matter, I doubt this is the case with the Highlander. I suspect the unsprung weight of a 17 and a 19 are going to work out to be so close as to be inconsequential. The tire cost can vary. You can go to www.tires.com and plug in some representitive sizes and see what the price points work out to be. I have a BMW that takes a 225/55x15 or a 225/45x17, and the 17s actually work out to be significantly less expensive. The savings in the cost of the tires paid for the rims after the second set of tires, including the full size spare. I don't know the cost of tires for the Highlander, but it is not difficult to find this out. I think that one of the other replies told you what the tires for that car are supposed to be. As a rule of thumb, for every inch INCREASE in the rim size, the aspect ratio DECREASES 5%. In a 225/55, the 55 is the aspect ratio. I increased the rim by 2 inches, so I decreased the aspect ratio by 10% (5 x 2 = 10). I'll make up a tire for the Highlander to illustrate the point; if the standard fitment is for a 245/75x17, then you would use a 245/65x19 -- two inches in the rim equal 10% in the aspect ratio. The resulting tire is so close to the same overall diameter that there are no fitment issues with the fenders or speed problems with the speedometer. Since Toyota offers the 19 as an option, then you could score a set of 17s and use them for snow tires if you live where this is a consideration.

The option ought to be 245/55x17 and 245/45x19, not the other way around.

And probably a bit harsher. I have 16s on the Supra with a 55% AR, and 17s on the Scion with a 45% AR. The Supra is a lot more comfortable. But not as comfortable as the Mazda with 65% AR... |
