Wheel & Tire woes for 2018 Ecoboost
My new 2018 Ecoboost came with 18" wheels and Goodyear Eagles. The handling is great but it rides like an industrial fork lift and the road noise is deafening. Can I change to wheels and tires that have more tire and less wheel? Owners manual and the shop manual both say NO, but no explanation offered as to why not. I would like to use either smaller wheels and tires with more sidewall like 17" wheels with 235/55/R17 tires (same net diameter) or keep the 18" wheels but go with 235/55/R18 tires instead of the stock 235/50/R/18 tires (1" more net diameter) and re-calibrate the speedometer. Thoughts? Has anyone experienced the same thing? Thanks!
