I own a 1994 Dodge Caravan with tires size 195/70/R14 on it. I wanted to know if I would be able to put 195/60/R14 on the van without having any issues with incorrect tires?

I want to put the 195/60/R14 tires on the front and leave the 195/70/R14 on the rear.

Not a good idea to have different sized tires on a vehicle. I once had a Dodge B200 van that I put larger tires on the rear - just like you want to do. Oh, it looked good and all, but I did notice that my highway speed was off and that stopping with the larger tires on the rear caused problems. It's up to you what you do, but I've already been there and done that and now know better not to do this type of thing again to my vehicle due to the safety factor.

To answer your question any good tire shop will have a chart that lists the alternative tire sizes for any vehicle that drives up. Ask them.

Having smaller tires on the front isn't going to hurt anything, as long as you keep the same size tire on both sides of one axle.

Not a good idea <quote> Agreed! Most, if not all tire shops nowadays will NOT mount a different size tire other than what's labeled on the drivers door.
Think safety first!

It is never a good idea to put two or more different size tires on the same vehicle, especially if the vehicle is equipped with Anitlock Braking System (ABS) because the "rolling" size will confuse the ABS control module with a slip/spin.
It's also not a good idea to move to a smaller tire because the smaller tire doesn't have the same carrying capacity plus your actual gas mileage will be affected.

Everyone that says it's a bad idea is RIGHT! In addition to what they've told you, consider the effect of putting the smaller diameter tires on the front. You've now changed the ride height of the vehicle and that changes all your suspension angles. The front end will ride lower to the ground. If you're set on doing this, you'd be better off keeping the original sized tires on the front--of course, smaller tires on the rear will also screw up your alignment.

Here's an article on tire placement: Replacing Two out of Four Tires

You should always have the tires with the most tread on the REAR wheels in a front wheel drive vehicle. The extra tread prevents spin out in turns.

You are not going to have a problem as far as driving but it affects your fuel milage and control the tirs on the frot will sit a tad bit shorter than the back but you'll be o k as far as getting back and forth just don do any real traveling the vechicle is designed for a certain tire size
