Help please... different size tires on an svx?
 

two newer than the other two. Maybe a lot newer. I assume the newer ones are on the front, don't really know. what does that do to the transmission if it has been driven several thousand miles? Any way to ck if transmission is damaged from that and if so, what does it hurt?
Would it hurt to drive with the FWD fuse in for a couple of hundred more miles?

Thanks,
Keith:cool:

Hi Keith

I bought a SVX in Idaho and the car had the same problem. I put the FWD fuse in and drove it home. I got the tires replaced as soon as I could and the car was ok. You would be better off driving it in FWD than AWD with the different age tires. Long term, it is not good for the car though. There have been some members who have driven their SVX for about a year that way, and they didn't have any problems that they know of. :)

Keith, when tyres are different rolling diameters this poses a constant strain on the clutches.

Which clutches are having to work all the time will depend where the difference may be. In my opinion [and I'm totally open to correction or criticism on this :p] the worst case scenario will be where the front pair and the rear pair are different rolling diameters.

In that case the rear axle will be turning at a different rate than the front [faster or slower, depending which pair is newer or larger] and this will put pressure on the clutch controlled by the C solenoid, the rear drive clutch pack.

Now if you had two taller wheels on one side of the car it will behave to the differentials like as if the car is cornering all the time. The differentials are designed to cope with a certain speed difference when cornering and may cope better than a front/rear difference.

The caveat to this is when you accelerate the car with taller wheels on one side it might affect the handling with the wheels on one side trying to cover more ground than the wheels on the other side.

Two wrongs don't make a right. But three lefts do make a right, eh Keith?

Joe :rolleyes: :D

[I concur with Earl. Unplug the fuse for a few months and then get a set all the same make and size]
