Default Tire Size will it fit

One of my co workers had new tires put on his van at work (we work at a car dealership) and after driving adout 30-40 miles the engine went Boon a pully shattered and did some other damage the van is not worth the repairs and he is want ing to sell the New tires to me for cheep.

The size is 205 and mine are 215s now every thing is the same I was wondering if they will since i think that that is the width

Thanks in advance.

Not only the width, what other information about the tire do you know?

if it is the same exact profile as the other tire, you should be fine. but be warned that a big car on slightly skinnier tires may chew up the sides of the tire some. but i do agree, more information is needed before a final descision.

If you have 215 and he has 205 and all other numbers are the same, for instance:
215/60R16 -vs- 205/60R16, then here'* what you're looking at:

The 60 above, describes the wheel-to-tread tire height as a percentage (the aspect ratio) of the previous number (which is the tread width in milimeters). So for the numbers above, your wheel to tread distance would be 60% of 215mm, = 129mm, whereas his would be 60% of 205mm, = 123mm. The difference, is 6mm in the radius of your tire/wheel system, or 12mm of diameter, which is about a half an inch.

That isn't so much, so you could probably get away with it, but I would personally never go smaller than the factory tires. It'* acceptable to get bigger diameter rims and a lower aspect ratio to compensate and give you little to no change in total wheel+tire system diameter, and you gain handling in doing so. Consequently you lose handling going the other direction. So to go from 215 to 205 would generally have a decrease in handling, although it may be small in your case, and your total diameter will be slightly smaller. For more radical changes it will also throw off your speedometer.
