Hi, I know this is an old thread but, it was very useful finding it to help me decide on upgrading my wheels and wanted to contibute if anyone else is considering doing the same. I just bought a 2006 Toyota Highlander Hybrid 4WD in excellent condition. I found the stock 17 inch wheels boring and wanted to update the car. I was able to find a set of 19 inch 5 spoke machined wheels for the 2008-2013 Highlander. The stock tire size for those 19" wheels is 245 55 19 but, I bought some Pirelli scorpion Verdes 235 55 19. They look great and really update the look of the first gen highlander. The have low rolling resistance so they didn't affect my gas mileage. This tire size converter was helpful to choose the tire size https://tiresize.com/converter/. The ride with the 19 inch wheels is just a little firmer but, also more stable on cornering and ride smooth. Great looking wheels, I'm happy I got them on. I'll try to post pictures when I figure out how to do it in this forum.
