Search by linked attributes

[poldec]

Hi
Im developing a website for a tyres shop.
I would need to have a advanced search able to find an item via its attributes.

for example:
each tyre has 3 sizes (width / height / size) (185 / 40 / 18)
each of these option has about 20 possibiliies = 20x20x20 = 8000 poss.

To do this I would use the attributes in 3 dropdowns but the problem is that the price depends of the combination of the 3 sizes.

I have a few knowledge in PHP and MYSQL and I know that I could use a new table for this.

If you know how to do this with the basic ZenCart or if you know an other solution already developped please help me!

Thank you in advance!

I would also be interested in this sort of mod as relating to weight.
