One tire punctured, have to replace all?
I have no idea what I hit when driving past a road construction site last weekend, now the passenger-side rear tire has a huge gash on the side-wall, basically irreparable. :cry:
My dealer still has the original Continental ContiTrac Ecoplus for replacement, but I was shocked to be told I would have to replace ALL FOUR tires even though only one is gone. When asked why, my dealer and a couple of stores all told me the ABS wouldn't work properly. :confused: After doing some research, it seems the problem is especially serious for AWD vehicles like my 2006 FEH, something to do with some kind of "differential"? Please excuse my ignorance :P I'm wondering if other owners have faced this surprise or issue or having to replace all tires just simply because one blew up? :angry: Now that I may have no choice but to get new tires, I'm wondering if the Michelin Latitude Tour is a better buy since it's only about $20 more than the original Continental Ecoplus? Should I go for the Michelin Latitude Tour over the OEM Continental Ecoplus? The Michelins are supposed to be quieter and better? :money: |

Yes, unless the tires are pretty close to new, you should replace all 4 on this type of AWD vehicle. I've had to do this with my Subarus as well.

I don't think that you need to replace all four but just in pairs or both rear tires.

For FWD it doesn't matter, so long as left and right are replaced together. |

If the rear wheels are spinning at enough of a different speed than the front tires, the AWD may be invoked - all the time.

The OP can change all four if they wish and I'd guess that a tire dealer would say this. To my understanding this only applies to AWD which has a center differential which the Escape doesn't. If it did the Ford Workshop Shop Manual wouldn't have a pinpoint test for proper operation which is to command 100% rear wheel torque and if the vehicle resists turning, it's working properly.

I don't know about the shop manuals, but the question is how does the AWD get invoked? Is it when the front wheels spin, or when the front and rear wheels are moving at different speeds? If the former, it is no problem to have different front and rear, if the latter, it could cause problems.

Page 173 of the 2005 FEH owners manual briefly mentions dissimilar tires could lead to impairment of the all wheel drive system.
The usage of a dissimilar spare tire/wheel can lead to impairment of the following: • Handling, stability and braking performance • Comfort and noise • Ground clearance and parking at curbs • Winter weather driving capability • Wet weather driving capability • All-Wheel driving capability (if applicable) There is nothing about needing all 4 tires with the same wear. I would guess tires on the same axle need to be about the same. |
