245/40/18

One of my good friends offered me a set oof 18" wheels and tires, for very cheap ($450). Will they fit my laser or are they too big? The tires are HR2's.

245/40/18 is a tall tire for a DSM, it CAN fit but they're so many varibles you are not considering.

1. What is the offset of the wheels?
2. What is the width of the wheels?
3. What are you suspenion mods?
4. Is the centerbore the same, smaller, bigger?

I have KYB AGX adjustable's

It says 245/40/18 then 93H. The centerbor is about the same size. Idk much about tires

Tires:
245 is the metric distance from the inside of the contact point to the rim to the inside of the farthest point of the tire wall.
40 is the percentage of the radius to the 245
18 is the diameter
The depth of the rim is calculated into each of these to figure out the total width.

The 93H is the speed rating. I don't remember what this is equivalent to, but it refers to what the top speed those tires are rated for... above that and their resistance to blowing is significantly reduced.
There should also be a traction/wear rating related, although you'll need to look up the manufacturer and model of the tire to find out.

Here's a great comparison site: http://www.miata.net/garage/tirecalc.html

Rim:
The offset is how far the center of the hub is from place where it bolts on.
The width of the rim changes the total radius of tire and hub by either squeezing the sides more (making the total taller) or less (flattening the tire).

This might help:

Grab a tape measure and find out what the total height of the combo is if you don't have a rim depth. You probably won't be able to measure the offset very easily. Check the total height against your
Just bolt one on and try it out on the front. Rotate the wheel all the way left, then right, and see if there is any rubbing by spinning the tire (out of gear).

Good luck!

Thanks for all the tips . I threw them on and they're about .5" from the strut..I drove around the block, hit a few bumps going about 40 and It was no problem. The rims look awesome. I'll post pics later, thanks for the help guys.
