    The bigger the wheel diameter vs the tire sidewall there will be an improvement in FE. Less CSA for roadbed contact/friction, less tire flex, lower heat buildup in the tire, improved FE.

    The "poor" traction CSA issue can be addressed somewhat by going with a WIDER wheel thereby allowing a wider tire tread.

    With alloy wheels the "net", overall, weight of a 20" wheel/tire combination could be less than a 19" (or even 17") wheel/tire combination. A "pound" of rubber may weigh more than a "pound" of aluminum allow wheel.

    "...Does the tire/wheel combo look good...No!.."

    69, going on 70, I'm of the opinion it looks good.

    "...Does it improve fuel economy..No!.."

    Yes, YES...!!

    Lower CSA for roadbed contact = lower roadbed friction/rolling resistance.
    Lower sidewall = less sidewall flex = lower heat buildup in the tire.

    FE improved overall...YES.!

    "...Does it improve handling or unsprung weight..No!..."

    Improved handling, YES, without doubt.

    lower unsprung weight, maybe. See separate post.

    "...Is this an example of Toyota losing focus..Yes!..."

    No, not in my opinion.

    All that being said I would change out to 17" right away.

    But then I won't even consider buying a Venza until I see the 4 cylinder with DFI.

    "...Toyota should offer..."

    The CAFE rules/regulations do not "allow" that.

    With 17" wheels the EPA estimates would undoubtedly differ.

    Like asking for a 5 speed now that the 6 speed is available.

    One of the reasons you now see the very same 6 speed transaxle on both 4 and 6 cyclinder engines. In the old days the 4 cylinder would probably have been coupled with a less expensive 4 speed, lower manufacturing cost trumping FE.

    No more...Good-O.
  • I think it's nice to know the transmission on the 4-cylinder is capable of handling the higher power output of the 6-cylinder engine and thus understressed.

    It seems you could go to Tire Rack and get a nice tire/wheel combination that would exceed the quality of the factory provided tires and wheels, but in a higher profile but smaller diameter.
    Depends how fussy you want to get.

    "I think it's nice to know the transmission on the 4-cylinder is capable of handling the higher power output of the 6-cylinder engine and thus understressed'.

    It is quite common anymore to have smaller and larger engines connected to the same transmission. It certainly has to be cheaper for the manufacturer. All they need to do is calibrate shift points, etc.
  • My 4cyl. (19") Venza drifts to the right; not all of the time but almost always on surface streets and the interstate. It's been particularly noticeable since I put the Blizzak snow/ice tires on. The Bridgestone dealer has checked all 4 tires and remounted them twice and advises that the tires are fine. He even gave me a free front end alignment which helped some (it needed alignment at 4500miles??) but it still drifts to the right. The Toyota svc. mgr. says that this is normal behavior because cars are designed to pull right as a safety feature (I never heard that one before). Both of my Subarus always tracked straight as an arrow. This is a very annoying problem. Any thoughts???
  • I recently had my 5000 mile service including rotating tires. My car drifts slightly to the LEFT when the steering wheel position is straight. They checked alignment, tire pressure and everything checks out. I'll wait until the next tire rotation and see what happens.

    Here's something for thought: On most surface streets, the streets are slightly inclined to the right, particularly in the right lane near the curb. This allows the rain to drain into the gutter. Maybe this accounts for your car to drift to the right, but it doesn't explain why my car drifts to the left.
  • Thanks. A leftward drift is interesting. My car can drift from both the crown of the road and from the left lane which usually has a gradual slope to the left...never goes left, just to the right. This will happen on both surface streets and the interstate but not all the time. It's an intermittent problem, that's the problem. My theory is that there is a steering issue with these cars and it may be partly due to the huge tires that Toyota chose to go with.

    Since it only happens intermittently I have to think it's the road your driving on.
    The toe and camber of the front wheels are aligned to drift to the right if you take your hands off the steering wheel as stated by your dealer.
    So I can't believe it has anything to do with the size of the tires or the steering on the Venza.
  • Dave - I just bought a new 2009 Venza and am having the same issue. I have determined the cause, in my case. Next time your out, pick a flat/straight road and try this test: 1) lightly release your grip while coasting (foot off the gas pedal). 2) Go back to the same point you released your grip, do it again, but this time give it some gas.

    I found that the drift right, and the degree of the drift, is directly related to the amount of juice I'm giving it. No gas, no drift. Light gas, light drift, etc. If I'm maintaining a speed, using cruise for example, once the Venza is at speed it does fine. Once I go to pass/change speed up, it veers right.

    Let me know.
  • CC- thanks! I'll give it a try.
  • wwestwwest Posts: 10,706
    Sounds as if you're describing torque stear resulting from have a longer halfshaft on the right side vs the left.
  • Is that considered "normal" or can it be corrected (under warranty?). It's very annoying.
  • wwestwwest Posts: 10,706
    SOP....pretty much normal for FWD and F/awd vehicles. After a while you should not really notice it except in an accelerating right turn.

    Have tried your suggestion and it works about 95% of the time however the car will sometimes drift during coast on flat road. I think the aggressive snow/ice tires are a factor. Will be removing the snows soon and will try again.
    Thanks for the suggestion.

    I got my Venza in November and put winter wheels on it right away. The winter wheels were 18" right off of my former Mazda CX-7... the bolt patterns and centerbore were a perfect fit. Dunlop WT M2 235/60R18. This was their 4th summer and they are too worn now for another winter.

    From the day I put those winter wheels on, I noticed the car pulling to the right. I was convincing myself that maybe it was the crown of the road or something... Or maybe I needed an alignment. But today I switched back to the OEM 19" wheels. The pulling-to-the-right is totally gone.

    The offset on those wheels was off by about 10mm from the OEM wheels, and the tires were a lot skinnier than the OEM's. So the wheels looked like they were set in from the fenders a little bit too much.

    I don't know why the snows pulled to the right... but it was definitely the snows.

    I also wonder whether they may have been ineffective because of that pulling... or wearing out faster.

    I just came across this thread because I was thinking maybe next year it would be better to get 245/55-19 snow tires and mount on OEM 19 rims. But there are no snow tires in OEM size! I know some dealers have put packages together, but what does Toyota expect us to do?

    :mad: My problem is since I leased my 2009 Venza on January 2010 I feel and all passengers feel all road imperfections and sharp bumps, low manholes and small potholes. This is a 4 cyl. with Bridgestone Dueler x/L 400 tires P 245/55R 19. PSI at 32 as recommended by Toyota. Previously I had a 2002 and later 2005 Highlander with Michelin tires and 17" wheel and I had always softer ride. What can I do since I am stuck for 38 month lease and a bumpy ride?

    Unfortunately that's one of the trade-offs when go to bigger wheels because you've got less rubber. Is there an upgraded Michelin or Goodyear tire in that size? I got rid of my Duelers on a Honda and upgraded to Michelin - BIG improvement in ride, noise and I haven't had a flat from a small metal staple either!
