To start with you may want to browse at http://www.tirerack.com and do a search for tires for your Intrepid. When you select the vehicle it should give you a tire size of 225/60/16. You can then narrow the search by selecting boxes below. I'd suggest selecting Touring, Grand Touring, All Season & Performance All Season. You can then view a whole selection. Also when you are looking at specific tires clicking on specs will give you a table showing specifications. The 1st 3 numbers under the heading UTQG have to do with relative tire wear or how many miles they would normally last. A higher number is better meaning they will last longer.
There are a number of tires in or slightly above your price range for example the Bridgstone Potenza RE910 at $67 looks decent. Anyway once you decide on a tire or two that look good and meet your budget needs write down the manufacturer, model and size and call some local tire places to get their best price. It should be fairly close.
Hope this is of some help.
