Tires

[Doug Wyman]

My specs for my Sport Trac say 255 /70 R16. My mechanic put on new tires for me and put on 225 / 70 R 16

I told him about it and he insisted my specs said 255. I checked three times and it is 255. Will this be a problem?

WARNING!



When changing tire sizes, we recommend staying within 3% of the diameter of the original tire. Any more than this and you face the risk of brake failure.

5.5% diameter difference. Did HE check your door sticker? :banghead:

Stay on top of it. He is trying not to eat the cost of his mistake.

Also time for a new mechanic..........

I believe the 255 is only for the Adren 20" rim and the 225 is for the Smaller sizes.



Not 100%..... what motor and year is your sport trac.

Ambulance chaser BS. I've had 265 series BFG's on my '07, which came from the factory with 235's, since the day I bought it new. As a matter of fact I had the selling Ford dealer install a set of 265/65/18's on the factory Limited wheels before I took delivery of the truck. I have only changed brake pads at all four corners one time in over 131k miles and I have been known to tow some pretty heavy stuff. The only reason I did that was because they were starting to rattle, the rears because of a lack of anti-rattle clips on the original pads. Not sure why the fronts rattled but all four sets of pads still had more than half of the pad remaining when I replaced them with new Motorcraft pads. They just got noisy. I swapped the front rotors for slotted EBC's about 20k ago only because the originals were starting to warp and cause a pedal pulsation. Still running the original rear rotors and they have never been touched.

1st Gen with 4.10 gears got 255-70-16. With 3.73 gears, 235-70-16 was stock.

My 2001 ST takes P255/70R16.

Look at the tire placard on the door frame of the driver's door. It will tell you what size tires your truck is supposed to have and the inflation pressure.



Undersized tires are very dangerous because they do not have the required load capacity as the stock tires.



I would make the mechanic change these out.
