#441 of 450 New Snows and TPMS by bob259 Nov 17, 2009 (8:21 am)
Got my new snows mounted on the spare set of wheels I purchased today and just had regular valve stems installed on them and no TPMS pucks installed. I found out the following. I have a Hybrid Limited and went into the small screen set up mode (hold dsp button) and reset the tire presure monitor to off. I have no warning lights or error messages... this is great news for those worried about the light staying on.
#442 of 450 Spinning tires during wet acceleration by kevinkjm Nov 19, 2009 (7:09 pm)
Does this happen to anyone? We have a 2005 FWD 6cyl highlander which spins out with the slightest touch of the accelerator from a stop or accelerating during a slow turn when the roads are wet. I've been driving FWD cars for 25 years and am quite familiar with torque steer and all sorts of other FWD symptoms if one is aggressive, but the Highlander spins out under the most conservative of driving conditions.   I thought it was the OEM tires, so I swapped them out with a set of Yokahama Geolanders HTS and didn't really see any difference other than the increased road nosie.   So now I'm puzzled... is it the tires? the vehicle's torque?   Does anyone else experience this with their Highlander?   Thanks   -Kevin Replies to this message: tidester (Nov 19, 2009 9:33 pm) worthflorida (Nov 20, 2009 12:46 am)

Replying to: kevinkjm (Nov 19, 2009 7:09 pm) I suspect that you're accelerating and turning a little faster than you think. In a turn, you're reducing the load on the inside tires and the frictional force on the tires is proportional to that load. Wet pavement provides a significantly reduced coefficient of friction. Also, the Highlander has a higher center of gravity than a sedan which tends to amplify the effect of reduced load on the inside tires in a turn. All of those factors result in slippage when you're accelerating too fast while turning.   tidester, host SUVs and Smart Shopper

Replying to: kevinkjm (Nov 19, 2009 7:09 pm) I have a 2003 Highlander V6 3.0L. I think your model is a 3.5L with more hp & torque. I live in S. Florida and it is the rain capital of the US. 56 inches a year and the only time the front wheels slip is hard acceleration on damp roads where the oil comes up to the surface. Other then all of the typical roads conditions, asphalt aggregate and climate can affect the road friction; have you every have the dealer check out your vehicle. You do have drive by wire and it could be a throttle position sensor or another one and the computer thinks that the engine is not up to the correct RPM/Speed for the accelerator pedal position. Since it is only happening on wet roads it could be just on the edge where the tires will break and not on dry payment.    On dry payment if the vehicle accelerates silky smooth which these engines are well know for it might just be the driver. The best thing is to get someone else to drive it and see if they have the problem. You just might have just a heavy foot and not realizing it
#445 of 450 bought new tires and wheels by gopcs Nov 24, 2009 (12:11 pm)
2010 Highlander Sport V6 AWD   Put off buying the Highlander for 3 months because of the unusual tires size and lack of tire choice. Finally, made decision and bought it knowing that new tires and wheels were coming.   Purchased new wheels and tires at Discount Tire. Liquid Metal F5 wheels, 8x18, 35 offset. Michelin LTX M/S tires 245/60R18   Had to return to store for rebalance. We are going on a 200 mile trip this weekend. We'll see how it goes.   One observation. Using GPS receiver that indicates MPH and distance traveled, the speedometer registers about 3.5 MPH faster than GPS (this is at 60MPH on GPS). This would be expected if the tire is smaller than OEM. But, the odometer shows distance traveled to be lower than the GPS registers. I might put the OEM tires back on temporarily and run some more tests. Does anyone know if the speeometer and odometer are driven from different mechanisms? If the speedometer is electronic, is it adjustable with appropriate software?

Replying to: gopcs (Nov 24, 2009 12:11 pm) I would not put to much in the GPS reading. Since it is not military grade and the the very short distance that it compares for speed travel there is not enough decimal places to get a real reading.   Get your tape ruler out and measure the circumference of the original tire, then with the vehicle up in the air measure the Michelins and compare the two for size.   Another easy way is to get on the interstate and click off on millage markers. If you have a another car and a friend that has nothing else to do, follow each other in the interstate and compare each others speed with the cruise set.

Replying to: worthflorida (Nov 24, 2009 2:00 pm) Or, just go here   http://www.discounttire.com/dtcs/infoTireMath.dos   and make it easy on yourself.   You'll find that the difference in tire sizes is less than .08 MPH 65 MPH !   Yes, that is point-zero-eight; less than one tenth of a MPH !!!

Replying to: gopcs (Nov 24, 2009 12:11 pm) Yes, the odometer is computer controlled. Without posting a LONG explaination, it is all tied to the transmission and computer with vehicle. Your odometer will register incorrectly as you explained and your gas mileage will be worse as well. In addition, don't understand why you would want to VOID the warranty on NEW vehicle by going with non-OEM wheels and tires on NEW vehicle. You, my friend are taking LARGE risk on NEW vehicle in my opinion. Just discuss this with reputable Toyota mechanic or service manager. I understand . .. it may be a long shot that your NEW vehicle would experience any issues. However, in the event you experience transmission problems or front-end problems, Toyota and dealership will look to YOU as being the issue with non-OEM parts impacting the problems. Just be forwarned . . . Today (11/25/09) big recall with Tundra pick up trucks . .. 2002-2003 with defective paint and premature RUSTING... I wonder how many potential lawsuits resulted in this BIG recall of Toyota pick up trucks...   Be careful and I got this advice first hand from experienced dealership mechanics and service manager... lower gas mileage + miles being incorrect. Now, if you have a significant warranty issue, they go by the miles on vehicle as well. They will see the non-OEM wheels and tires and hold YOU accountable and could void warranty using that as a GOOD excuse as well.... Good luck !
