I have 235/60/16 tires on my Freestar. My question here is, can I put a smaller sized tire on this 16inch rim? If so, what size tire can I use? I am looking to save money. Thank you.

Yes as long as u change the rims also not just the tires these numbers 195/60/15 195 is tire width 60 is tire height and 15 is rim size, most all Hondas will fit up to 215/35/18 with no rubbing issues on factory suspension ..... Every time the rim size changes u have change the height of the tire so it will fit some go as far as " stretching " the tire to allow larger rims or extreme offsets

The closest you can do is to hold them side by side and compare them. You might take one of your wheels to a tire store, and have them show you 16" tires. Try to match them with those that are exactly the same HEIGHT. The width and the rims size don't matter, what you are shooting for is diameter. Don't be at all surprised if the tire store dude argues with my statement here.
Be blessed.

yes you can but you need to find a tire that will have the same diameter or no more than 5% greater or smaller. check this site: http://www.miata.net/garage/tirecalc.html

you have to be careful to make sure the smaller rim don't touch the caliper.

If you want more tire and can not go with bigger height, either you should put on a lift kit to give you more clearance or get smaller rims.

This depends a lot upon what size rims you have, and what your driving conditions will be. Generally, the type of tire that is already in use on the car should be fine (the tire type and size are printed on the side of the tire ... usually something like "P175 65R14" or something like that -- it's in big lettering on the sidewall). The "P" in my example is for "Passenger" cars ... the first number (175 in the example) is the width of the tire tread in Millimeters ... the second number (65 in the example) measures the depth of the tire -- the distance from the rim to the tread ... "R14" gives you the radius of your rim.
The width of the tire affects the handling of your car (wider tires give you better handling) but can also contribute to road noise -- the wider the tire the noisier it is. If you've heard the noise from a Jeep with mudders (extra wide tires for driving in muddy conditions), then you understand the noise. With a Corolla you will probably not be facing too many off-road situations, so between 145 and 185 should be fine for a first number.
With a corolla, I would always recommend a passenger tire ... other ratings are for trucks and load-bearing vehicles.
The depth of the tire can also affect handling and road noise. The second number (65 from the example) gives you the depth. If you are looking for low-profile tires, this would be a smaller number. Although this does affect the handling and noise, it is mostly about the look of the tire. If you desire to have a family-car look, go far something in the range of 65 ... A little more or less will not have much effect that you will notice, but a larger number will make the car jolt less whan you hit a pothole or a bump in the road.
"R14" from the example is the most important number, and the only one that cannot change without changing the rims. This is the radius of the rim, and MUST match or the tire will not fit, or will pop off the rim while driving. Read the sidewall of the tires you have now, and use the same R number. Generally, anyone mounting tires will make sure that you have the right size before they will put the rubber on the rim for you -- it is as dangerous to mount a wrong-size tire as it is to drive on one.
If you have more questions about your tires, I would recommend visiting a tire retailer and speaking with someone directly -- they are generally well trained about tire specifications, and can give you more detail about the effect that each aspect of a tire will have on your driving experience. Having driven a few Corollas, I always used P175/65R14 on mine (I think it is pretty standard) but please be sure to check your tire to make sure you have the same size rims.

The tire circumference must be the same as the factory tire circumference otherwise your speedo will be out. If you increase your mag size then your tire wall must get smaller to maintain that same circumference. If a tire shop has sold/changed the tires for you it is their responsibility to ensure the car leaves their shop in a safe and legal condition.

both tires will fit on the 15 inch rim
But be advised make sure you have same size tires on the drive wheels being as your car is front wheel drive u want both the front tires to be the same size
if this is not done u will burn up your transmission
if you have to put a odd ball tire on put it on the rear

exact opposite is true for rear wheel drive car on a rear wheel drive car u want both rear tires to be the same size



Dimension Tire A: 195/65 R 15
(25 x 7.68 x 15) Tire B: 215/60 R 15
(25 x 8.46 x 15) Difference Width Sidewall height Overall height Circumference 7.68" (195.00mm) 4.99" (126.75mm) 24.98" (634.50mm) 78.48" (1993.34mm) 8.46" (215.00mm) 5.08" (129.00mm) 25.16" (639.00mm) 79.03" (2007.48mm) +0.79" (+20.00mm) +0.09" (+2.25mm) +0.18" (+4.50mm) +0.56" (+14.14mm)

the stock rims should be 16" making the tire size 205/55/16. let me know if you have a different rim size. you can look at the tire size on the tire sidewall and the last number is going to be your rim size. if it's a 15' rim the tires are 195/65/15 and finally for 14" rims the tire size is 195/70/14. hope this helps.

yes you can, basically you can just about put any size tire on as long as it fit however 215 is the height of the tires, by putting smaller or taller tires than recommended by the manufacture will effect you speed odometer. 70 is the width of the tires, the wider the better traction and 15 is the size of the tires that will fit the rims. Here is example...

Specification Sidewall Radius Diameter Circumference Revs/Mile Difference 215/75-15 6.3in 13.8in 27.7in 87.0in 728 0.0% 225/75-15 6.6in 14.1in 28.3in 88.9in 713 2.1%

If you change from the manufactures original tire size, not only will you have steering and handling problems but you will have problems with the performance of the van. The pcm makes thousands of calculations every second to keep the engine running at it's peak performance. These are based on everything remaining original (Tire Size). If you change the tire size it will alter everything the computer does. Including making your speedometer and odometer give you false readings. Your best bet is to stay with the original tires.
