Front tires were taller than rears

[jorton]

First I tried to tell the full story but there are too many details. So, to make a long story short: When I rotated tires on both cars today, all four fronts were taller than the rears and both cars have matching sets of four.

Is there a simple explanation for this?

Your vehicle is from Thunderbirds?

mori, I was going to post twin axle Atkinson...but refrained.

I should have remembered Lady Penelope.

LOL! It looks like he's talking about two vehicles, hence the "four fronts".


jorton,

You made the story a little too short. What cars are those? What exact tire sizes on each axle?

 

[jorton]

99 Mercury Tracer: Dunlop P185-65R14, both axles.

05 Focus: Federal P195-60R15, both axles.

Yes, there is a simple explanation .....

You have to be sober when you do your tire rotations.

Shocks and an optical illusion.

OK, so how exactly did you establish that the fronts are taller?

 

[jorton]

I did one side at a time using 2 scissors jacks and I had to raise the rear jack some more to get the wheel from the front on the back.

And when you post.

1. Jack both ends of car to the same height with both wheels off the ground.

2. Measure the distance from the center of the front and rear hubs to the ground.

3. Think about what you just observed.

I di'dnt drunk drive to discont tires and the weels didnt fal off the cars today whats da prablum'

On cars where I have to jack the body rather than the axle, I usually have to give the jack a few more pumps to fit the tyres back on the rear.

The fronts usually have limited travel downwards, through droop bump stops...they are pushed against the stops and don't move.

The rears don't...so when jacking up the rears, the wheels come off when an elastic (bushing) limit is reached. leave a few minutes, and the hubs drop even more.

(Or what the Mod said)

Believe I'd a found a more accurate measuring system before posting that here.

Actually it is ENTIRELY possible due to several factors.

1. Wear
2. Deferent spec versions of same tire. (For instance the BFG tire on a Ford Explorer is available in both T and S speed ratings and the tires are more than 3 inches off in circumference which messes up the ABS and Traction control BADLY)
3 Different brands of tires
4. Different types of tires touring or performance oriented

makes a difference.

Glad someone finally brought that to my attention!

After selling used tires for the past 30+ years I'd never have figured it out on my own. I expected the op to know that his tires are the same, as that's what he originally posted.

Bob, we'll make yet a cynic out of you!

You should,,, It's your signature!


It's better to be "thought" a fool than to post on BITOG and remove all doubt ..
