OT 2016 Toyota Avalon Rough Ride
I love my 2016 Toyota Avalon Limited....except for the rough ride. You
can feel most every bump, expansion joint, pavement crack and manhole cover on the road. Even shallow potholes slam and are a teeth-jarring experience! The tires are inflated to the door sticker pressure and there's nothing wrong with the suspension. I know Toyota gave this trim model a "sportier" suspension with 225/18/45 skinny tires on 18 inch wheels to improve handling- rather than go with the fatter 215/17/55 on 17 inch wheels on the lower trim models. It's getting to be tire time and I wonder if it might be worth buying a tire/wheel package in the smaller size. Would the taller 55 sidewalls absorb road bumps better? Any problems with transmission shift points, speedo readings, any of the electronics/gauge stuff, etc.? -- Teacher: Why are you late? Student: Class started before I got here... |

I made the dealership switch the wheels with another vehicle to the 18" wheels. I knew 19" tires are expensive and I wanted more air in them for a softer ride. Does your Avalon come with suspension settings you can change? My 2004 Avalon was a very comfortable ride and we loved it. An Avalon is basically a Lexus ES and it should be a softer ride. More air down there (volume in tire) the softer the ride. |

Nope, no changeable suspension settings- though the transmission has the three shift point setting buttons. I had looked at the Lexus ES 350 and best I could tell, the main difference between it and the Avalon Limited was its auto swing-away steering wheel at engine shut off, Things like that are OK if you buy it new or only a couple years old with warranty and only intend to keep the car during the warranty period or maybe a few years after. Outside that, those added complexities just become expensive things to fix when they break, unless you're DIY. Even then it can get pricey. Some are OK I guess because you don't necessarily need to use that part anymore if it goes kaput. |

Any problems with transmission shift points, speedo readings, The speedometer depends only on the circumference of the tire, which would be the same iiuc. The shift points also, I think. There are online calculators available where you can put in the std tire size and whatever you want to compare it against and it will do the math and give you the speedometer difference. Generally you want to stay within a few percent and IMO having it read out on the high side is better to help avoid tickets. |

I had looked at the Lexus ES 350 and best I could tell, the main difference between it and the Avalon Limited was its auto swing-away steering wheel at engine shut off, somewhat plusher interior and better audio system, an extra year of bumper-to-bumper warranty, fancier dealership decor and way better looking and really hot sales babes. I was ready to pop for the Lexus- but was offered a really good price on "last year's" 2016 Avalon Limited after the 2017s had already been in the showroom a month or two. I usually keep a car a long time so the "lost year" in resale value really wasn't an issue for me. I counter-offered a few thousand less and ended driving out for what was pretty close to what I felt was a "gimme" price. Looks like this may be a common issue: https://www.toyotanation.com/threads...-help.1602602/ |

I'm curious why the slightly wider tire is a "skinny" tire while the slightly narrower tire is a "fatter" tire, but I'll put that aside. Doing the math, the 225/45-18 is approximately 659.7mm (25.9") tall when new, while the 215/55-17 is approximately 668.3mm (26.3") tall when new, with a difference of about 1.3% between the two. Sidewall heights are 101.25mm vs 118.25mm, respectively, but I don't think the harsh ride is due entirely to tire size. Tire construction could still play a role, with some tire models having a stiffer sidewall than others. You say there's nothing wrong with the suspension, but if I needed to tame a harsh ride that's where I'd start, especially with the shocks. Spring rates could also be a contributor. |

I would defintely be checking to see if a 16 inch rim will clear the brake calipers and if so go to a 215/ 65 16 or possibly even a 215/70) which will change the speedo calibration by a small amount but not cause any other issues)or 21 |

I really liked the stiffer suspension on the Chrysler 300M with the sport package option until moved back to KS on the dirt roads...then it was a tooth-rattling experience for sure. Plus, it had so little road clearance for mud sold it after a couple years. Anyways, back to the main thread, fnDrim(17,215,55)/fnDrim(18,225,45) ans = 1.0130 Is only 1% difference overall diameter/same for circumference for calibration error... fnDrim(17,225,55)/fnDrim(18,225,45) ans = 1.0297 if go back with 225. Surprisingly, even the 16" w/ 65 ratio is about the same... fnDrim(16,215,65)/fnDrim(18,225,45) ans = 1.0397 The section height portion change with the SW ratio compensates even more than the rim diameter change... -- |
