Toyota Repair Problems? Ask a Mechanic for Answers ASAP
What was the overall tire size was on a 19 inch wheels on the Venza that you drove? Was that also a 2015?
What do you have the tire pressures set at when it's cold?
First of all I don't have a clue what tire was on the 19 inch wheel there are multiple tire suppliers and wheel options for any one particular Toyota model. I don't have a crystal ball. At this point I don't think were communicating very well I will opt out you can work with another expert. I Apologize if I made the assumption that if you noticed a drastic difference you would've taken note to the tire size tire brand and style of rim that was on the vehicle that you are satisfied with the ride on.
Unfortunately the salesman was not truthful with you. No offense but he probably got a better commission on the upgrade on the tires and overall package :-(. Anytime you go with a larger rim and you only have so much wheel well space to work with you have to reduce the size somewhere and typically that's done on the sidewall of the tire or the profile of the tire. The smaller profile on the sidewall of the tire will always cause a stiffer ride. These are more of a sporty tire for race car type driving so to speak. I think it is incumbent upon the dealership to make this right for you either switching out the tire and rims or providing another vehicle and swapping you over to the option that you like better on the 19 inch wheels. I am providing a link on this website you can manipulate the numbers so that when you get the tire sizes and rims you can see the difference in the sidewall profile and can make a determination on what to do with the tires. It is very difficult to change the tire on the 20 in rim without affecting the overall size because if you affect the overall size it will affect the ABS system and the speed information to the computers.
You are welcome. Play with the calculator and it will make sense.
